Suggested January 2024 Cosmic Cartographers Release A More Accurate Map Of The Universe’s Matter
When the universe first began about 13 billion years ago, all of the matter that eventually formed the galaxies, stars, and planets of today was flung around like paint splattering from a paintbrush.
Now, an international group of over 150 scientists and researchers have released some of the most precise measurements ever made of how all of this matter is distributed across the universe. With a map of that matter in the present, scientists can try to understand the forces that shaped the evolution of the universe.
[Related: A key part of the Big Bang remains troublingly elusive.]
The team combined data from the Dark Energy Survey (DES) and the South Pole Telescope, which conducted two major telescope surveys of the present universe. The analysis was published in the journal Physical Review D as three articles on January 31.
In the analysis, the team found that matter isn’t as “clumpy” as previously believed, adding to a body of evidence that something might be missing from the existing standard model of the universe.
By tracing the path of this matter to see where everything ended up, scientists can try to recreate what happened during the Big Bang and what forces were needed for such a massive explosion.
To create this map, an enormous amount of data was analyzed from the DES and South Pole Telescope. The DES surveyed the night sky for six years from atop a mountain in Chile, while the South Pole Telescope scoured the universe for faint traces of traveling radiation that date back to the first moments of our universe.
Scientists were able to infer where all of the universe’s matter ended up and are offering a more accurate matter map by rigorously analyzing both data sets. “It is more precise than previous measurements—that is, it narrows down the possibilities for where this matter wound up—compared to previous analyses,” the authors said.
Combining two different skygazing methods reduced the chance of a measurement error throwing off the results. “It functions like a cross-check, so it becomes a much more robust measurement than if you just used one or the other,” said co-author Chihway Chang, an astrophysicist from the University of Chicago, in a statement.
The analyses looked at gravitational lensing, which occurs when some of the light traveling across the universe can be slightly bent when it passes objects like galaxies that contain a lot of gravity.
Regular matter and dark matter can be caught by this method. Dark matter is an invisible form of matter that makes up most of the universe’s mass, but it is so mysterious that scientists know more about what it isn’t than what it is. It doesn’t emit light, so it can’t be a planet of stars, but it also isn’t a bunch of black holes.
[Related: A key part of the Big Bang remains troublingly elusive.]
While most of the results fit perfectly with the currently accepted best theory of the universe, there are some signs of a crack in the theory.
“It seems like there are slightly less fluctuations in the current universe, than we would predict assuming our standard cosmological model anchored to the early universe,” said analysis coauthor and University of Hawaii astrophysicist Eric Baxter, in a statement.
Even if something is missing from today’s matter models, the team believes that using information from two different telescope surveys is a promising strategy for the future of astrophysics.
“I think this exercise showed both the challenges and benefits of doing these kinds of analyses,” Chang said. “There’s a lot of new things you can do when you combine these different angles of looking at the universe.”

Overview Of The Salesforce Release Management For A Business
One must note that under Salesforce, the process for release management is not an isolated one. It is linked with the business’s other processes, like change management, the objective of the business, governance, and additional aspects of the company associated with the business.
The release management process can be managed jointly by the steering committee of the company or the Center of Excellence, often referred to as COE, to ensure direction and success.
The objective of every business for the release management processThrough an organized process for release management, companies attempt to get a reputable, reliable and process that is independent of resources for boosting business value.

Components of release managementGiven below are the components of release management-
Release cycles
The change management process
Alignment with the release on Salesforce
Team structures that are planned and managed
Technological control
Businesses should note that change or release management does not comprise one process. There are several departments involved in this process. There have been several instances where it has been seen that every department of the organization has a unique process for release management that is different from the others.
Consistency and visibilityExperts recommend all the processes linked to release management in an organization should be standardized and streamlined for every user. This is because they are deploying the same resource, foundation, and platform for incorporating their business processes. If they are not streamlined, it is difficult for the company to maintain governance.
For boosting good governance, the processes about release management for every department in the company should be consistent and visible. This means every action of the whole team should be streamlined and supportive in the above endeavor.
The cycles for release managementThe varied sets of customer needs are looked after by several systems. There should be one centralized system for managing them. If they are managed in one place, then the other team members will have access to improved visibility and can track changes easily.
All of the requests for these changes should be prioritized. Moreover, the need of a steering committee is needed to assess the requirements frequently, with which changes in the above system can be prioritized.
Experts from the esteemed name in SalesforceDevOps, Flosum, suggest that if you talk about the implementation phase, then the whole IT and business teams should remain in touch with one another and have proper communication.

Understanding the process of change managementDevelopers can change the sandbox, and they can show any other changes in it too. When the features are completed, they can later be shifted to the QA environment too.
The QA tests the features as per the necessary documentation, after which it can be shifted to the department for unit testing. In this manner, the process for change management commences. On top of this, the components for change management are reviewed.
They include the test cases, the documents for requirements, the production code, and others for the process to be completed successfully.
Alignment with Salesforce ReleaseSalesforce regularly upgrades its code, and so at the time, it can be challenging for businesses to release their code aligned with Salesforce. This is why they need to answer the following questions-
How should these changes be tested?
The release of these changes before and after the release
Business values of these changes when compared to Salesforce’s new features
What features should be planned for taking up?
The number of users that have been affected by the internal release
The number of sandboxes that are available for testing internal changes

The structures of the teams should be planned and managed wellThe release should be divided into many categories during planning like enhancements, fixes, trust, projects, and more. Separate teams should be formed for these categories.
The production team will control the fixes while the enhancements are looked after by the team for production support or project teams. The above also depends on the changes that are needed for the code lines.
If you examine a project team, it is generally broken down into the following-
Business team- This team is primarily responsible for making changes in light configurations that include ways to create and manage users, the territories, the data, and the page layouts by assigning layouts to different users. Moreover, the management of the above relies on the permission handed out to every member of the team and business customers.
Team for sales and service- This team has users accountable for managing the early cycle, quality of the software team, change management process, and more.
Teams for project enhancement – These teams are responsible for managing changes in small projects. For example, they make changes to visual pages, triggers, or small changes to the present integration.
In conclusion, it can be said that project teams are generally responsible for big and complex changes. They have multiple independencies across the other eco-systems of the business, like the ERP systems or any system that depends on it managed by the above teams.

Check Out The Most Extensive Map Of Black Holes Ever
At first glance, this glittering array of white dots against a black background looks like any other night sky. In reality, this image captures something much cooler— those starry white spots are actually thousands of supermassive black holes captured via radio signals. It’s the most detailed map of black holes—over 25,000 of them—ever produced to date.
Each of these black holes is swallowing dust and gas at the center of their own galaxy, millions of light-years away. These intense, hungry spirals create enough radiation, on multiple wavelengths, to reach us here on Earth. If these black holes weren’t actively devouring space particles, they would be nearly impossible to pinpoint because dormant black holes don’t give off any detectable radiation, rendering them more or less invisible.
Even in the midst of a cosmic meal capturing an active black hole, let alone thousands of them, is no easy task. The black hole’s ultra-low radio wavelengths were detected by the Low Frequency Array (LOFAR), a network of 20,000 radio antennas scattered across 52 locations in Europe.
LOFAR is currently the only radio telescope network with the capability to produce high-resolution images at frequencies below 100 megahertz. As a radio wave travels across space, its frequency decreases, and so does its energy. Since signals become harder to detect at lower energies, and the energy of a wave decreases as it travels millions of light-years across space, highly-sensitive arrays like LOFAR are key to detecting the energy signatures of black holes and other phenomena across space.
Once the signals are picked up by the network of antennas, the data can be compiled into images like the one above. In this particular case, researchers compiled the radio wave data collected from each antenna to estimate the location of each black hole. “This is the result of many years of work on incredibly difficult data,” explains astronomer Francesco de Gasperin of the University of Hamburg in Germany. “We had to invent new methods to convert the radio signals into images of the sky.”

LOFAR faces a significant obstacle avoided by space-based telescopes: the ionosphere. This outermost layer of the atmosphere forms a shell of electrons and charged particles around the Earth. Stretching from an altitude of 50 kilometers above the surface to an altitude of 1,000 kilometers, it’s where the atmosphere meets the vacuum of space.
Ultra-low frequency radio waves, below 5 megahertz, are reflected back into space when they hit this atmospheric layer en route to LOFAR’s antennas on the Earth’s surface. To correct for ionospheric interference, the team of astronomers developed algorithms run by supercomputers to filter out interference every four seconds while collecting radio emissions.
“After many years of software development, it is so wonderful to see that this has now really worked out,” says astronomer Huub Röttgering of Leiden Observatory in the Netherlands.
This first image, which covers four percent of the Northern sky, combines a decade of development and analysis, and nearly 11 days worth of radio emissions absorbed by LOFAR. Researchers plan to image the entire Northern sky via ultra-low frequencies as part of the LOFAR LBA Sky Survey.
The full results of this experiment are due to be published in the journal Astronomy and Astrophysics.
Xiaomi Mi 7: Release Date, Specs, And More
The next flagship Mi smartphone from Xiaomi, the Mi 7, is not much far away now. If you weren’t impressed with the Mi 6 from last year, then you probably might get what you want with the upcoming Xiaomi Mi 7.
The Chinese manufacturer has been making some really good phones ever since it came into existence. They make premium quality phones with the latest hardware and price them really affordable. The Xiaomi Mi 7 will be a flagship smartphone that will compete with the likes of Samsung Galaxy S9, LG G7, OnePlus 6, Sony Xperia XZ Pro, HTC U12, and more.
Xiaomi has made a very good name in countries such as China and India. In fact, these are the company’s main markets and due to the demand for low-priced devices in these markets, especially, India, its presence keeps on growing day and night. The Mi 6 was a beast and now rumors suggest the Mi 7 will also be nothing less, if not way better.
Xiaomi Mi 7 rumors
There have been a handful of rumors about the Xiaomi Mi 7 already and things are looking good for prospective buyers. Let’s get right into it!
Display and Design
6-inch LCD/AMOLED display
No in-display fingerprint sensor
As per most of the rumors and reports that we’ve come across, the Mi 7 will very likely follow the 2023 trend of slimmer bezels and a taller display than usual. Xiaomi was, in fact, the first major name in the smartphone industry to try a design outside the traditional 16:9, coming in with the OG Mi MIX that had an aspect ratio of 17:9.
The tech giant has further refined this design and recently launched the Mi MIX 2, Redmi 5 and Redmi 5 Plus with the much better 18:9 aspect ratio, meaning an even much taller screen than the Mi MIX. The fact that this design is already being used on Xiaomi’s budget phones means that it could be the new trend for the company, further asserting the rumor that the Xiaomi Mi 7 will also sport this trending design.
According to a recent report, the Mi 7 will get two variants: a standard model and a Plus model. Where the former will rock a 5.65-inch screen, the latter will come in with an even bigger 6-inch Samsung-made OLED display with a QHD resolution.
Even better, an XDA report points to an Always-On-Display screen, where users will be able to see things like time, date, up to 3 notification badges and battery level.
The previous Mi 6 sported a glass/ceramic body which gave the device a premium look. As per an alleged Xiaomi Mi 7 image that leaked out a while back, the company seems to be continuing with a glass back panel, but we still don’t know if a ceramic model will also accompany the standard model.
Hardware
Snapdragon 845 chipset
6/8GB RAM with 64/128GB internal storage
Some of the hardware specifications of the Xiaomi Mi 7 have been officially confirmed. For example, we know that the phone will feature the Snapdragon 845 SoC, as it was confirmed by the CEO of the company.
In yet another leak, a screenshot that claims to contain specs of the Mi 7 has just surfaced online, all but adding more weight to previous rumors. In the screenshot, we can see things like Qualcomm Snapdragon 845, 8GB RAM, 128GB storage and a massive 4480mAh battery, which honestly sounds too good to be true.
Unlike previous cases where a flagship Mi device was always the first to rock the best and greatest processor available, it appears that this year will see some tweaks to this trend. Apparently, reports surfacing from China suggest that there’s a Xiaomi Mi MIX 2S in the works and this could be the first handset to rock the new Qualcomm Snapdragon 845 SoC. As it is, this MIX 2S will be unveiled before the MWC 2023, thus beating Samsung to becoming the first to rock the SD845 chipset.
Other touted Xiaomi Mi 7 features include Dirac audio technology, aptX and aptX HD Bluetooth audio codecs, dual-SIM support, non-expandable storage, and NFC.
Camera
The Xiaomi Mi 6 included a dual camera setup which was pretty good in outdoor performance. Expect a similar setup on the Mi 7 as well, but with improved lenses, especially for low-light photography. The cameras are said to have a resolution of 16MP, including the one on the front.
There will definitely be improvements to the camera and the software, so expect the phone to take great pictures straight out of the box. Furthermore, the Mi 7 will include things like real-time Bokeh effect and electronic image stabilization.
Battery
Now, this is one thing that most users are always interested in. The previous model came with a decent battery with a capacity of 3350mAh. With the Mi 7 and Mi 7 Plus, we believe the battery capacities will be slightly more., especially since the phones’ footprints will be bigger and thus able to accommodate bigger batteries.
Despite the too-good-to-be-true rumor that points to a massive 4400mAh unit, a recent discovery made by XDA points to a 3170mAh battery unit. As for the Mi 7 Plus, we could be talking a slightly bigger 3500mAh unit, but don’t be surprised if things get a little bigger. Also, as mentioned earlier, the devices will most likely support wireless charging as well as the typical wired fast charging technology via a USB port, which will also double as a headphone port. Whether Xiaomi will jump to the newest Quick Charge 4.0 is still unknown, but hopefully, it does so.
Software
In terms of software, the Mi 7 will ship with the latest Android Oreo. Since current phones are either running MIUI 9 or will be getting the update soon, the Mi 7 will definitely come with MIUI 9 that’s based on Oreo (as of this writing, MIUI 9 is based on Android Nougat). This will include several new features and a much cleaner interface than before, but more importantly, Project Treble will be baked in the device out of the box.
Xiaomi Android Oreo update release date
June 2023 release rumored
Yes, the question that is on everyone’s minds. When will Xiaomi announce the Mi 7? Well, we have had mixed reports regarding the launch of the Xiaomi Mi 7. Where some had pegged the date to MWC 2023, newer reports claim otherwise.
According to latest reports, we should expect the Mi 7 to hit stores sometime in June 2023, in China whereas release for India and Europe could take Q3 2023.
Xiaomi Mi 7 price
Another important question. How much will the Xiaomi Mi 7 cost? Since Xiaomi is known not to charge a lot of money for their flagship smartphones, you can expect the Mi 7 to be priced favorably. Rumors suggest that the standard variant may start at 3,000 Yuan, which is about $475, effectively making the Mi 7 the most expensive in the series.
Why Does Cleaning A Computer Matter?
Before starting this article, let me tell you something that you might not be aware of; that is February 13th every year is known to be “Nation Clean Out Your Computer Day”.
By cleaning, we do not mean cleaning off the dust from your hardware devices like your CPU, cleaning your desktop screen, or arranging your PC table, which most Indian mothers typically do once a week while dusting the house. Here, cleaning your computer means removing the unwanted files and software from the system, keeping your hard drives free from unwanted storage, and keeping all the required programs up to date.
Why is it Important to Clean a Computer?The obvious question which comes to mind is, why one should bother cleaning a computer?
The primary reason behind it is that it keeps your data protected. Also,updating all the software, specifically anti-virus and anti-malware programs, up to date minimizes the chances of any loopholes in the program’s security, ensuring that viruses, malware, and remote “hackers” stay out of your system.
Not only this, a regular backup of all the required files might help you when you accidentally delete some of your files. Also, defragmenting your hard drives properly might save them from getting corrupted, and deleting unused programs will increase the system’s efficiency.
Hence, cleaning your computer is essential.
How to Clean Up the Software?Now we all know how to remove the fingerprints from the screen or dust near the PC, but let us see how to clean up the software −
(It’s essential to clean the “mind” as much as you clean the “body”)
Keep a backup of all your data for obvious reasons like they come in handy if any data gets misplaced or even when you want to transfer your device. Now you can back up all your data either in some physical location like hard drives or even store them online in “clouds,” which makes sure your data is secure. Also, don’t forget to back up every week and not just once since more the new files you add, faster back up you need to create for those files.
Always keep your anti-virus and anti-malware programs up-todate so that there are no chances of any loopholes in the program’s security, ensuring that viruses, malware, and remote “hackers” stay out of your system.
Whenever you update your software, check that you only keep that software in devices you regularly use so that no space is getting used by some unwanted app or software. This will also improve the RAM efficiency of your system.
Also, always make sure that your PC workspace is clean, and only that software is present there, which you need daily, and all shortcuts are deleted.
Inside your main hard drive, make sure you don’t just pile up files in one folder, it’s essential to keep your files organized in different folders as that makes it easy to search the file you require, and you can easily remove unwanted files in this way from your device.
Also, along with cleaning the fingerprints on the screen, it’s imperative that you also clean your digital footprints. That is, whenever you sign in to some new site, make sure you log out before leaving or remove your search history if you did any search for some sensitive data into your browser and never allow any sites to save your info like name, passwords, social security number or bank information. This will keep you away from a lot of trouble happening online.
And, the last step would be to wipe out all the devices which are not helpful to you, for example, any pen drive or hard disk which you might no longer use. You can give them away to someone who needs them or sell them to some store but before giving your system, make sure that you factory reset and remove all the backup from that device. Otherwise, it may lead to some identity theft or stealing of your data, or hacking your device.
This Entourage Of Weirdos Hangs Out In Earth’s Cosmic Neighborhood
Earth is a planet of habit. It rigorously adheres to a whirlwind of a daily schedule, spinning through its tasks (mostly: spinning.) In terms of long-term plans, it has those down too. It orbits the Sun every 365 days 5 hours 48 minutes 46 seconds, thank-you-very-much.
That’s not to say it doesn’t change things up periodically. It goes through phases, sometimes tilting its northern hemisphere towards the Sun, and sometimes the southern hemisphere. It’s good to mix things up.
During its orbit, Earth sticks to a well-worn path around the Sun, minding its own sweep of the solar system just like it has for 4.6 billion years. It doesn’t get out beyond that, but Earth isn’t lonely. It has plenty of visitors. One group is stopping by this weekend to party with the planet.
Like many of the other meteor shower crews, the Orionids stop by once a year, dropping in like clockwork with a big, enthusiastic show. These are the friend groups that Earth catches up with every time they’re in the same place, delivering consumable hostess gifts of dust and debris into the atmosphere, decorating the night sky with a light show in the process.
Of course, it’s not like meteor showers spring out of the sky fully formed. Just like Earth, they’ve got a history. In this case, a family history. Earth knows their parents too, though the comets don’t drop by nearly as often. The last time Earth saw the Orionid’s mom Halley was in 1986, and it’s not going to see her again until 2061. It takes a long time to travel into the bustling metropolis of the central solar system from where she lives, way out in outer reaches of the system.
It’s cool though; Halley’s other kids, the Eta Aquariids, will stop by in May. Halley’s trips to the inner solar system always give the Aquariids and Orionids more material to work with, even if that material does come from Halley herself, melted away by the heat of the Sun. Comets are like that. Halley stops by more often than the other comets, but it’s clear that the visits really wear her out.
Earth has plenty of other nearby neighbors. But luckily, they keep to themselves. These Near Earth Objects have a passing acquaintance with the planet—fellow commuters that know the other one is there, but who don’t end up making so much as eye contact. At least, that’s the hope. Researchers have identified about 16,885 NEO’s so far, and would really prefer that they each stayed in their own lanes.
Earth is still finding the remains from the last time a really big NEO got too close. Dinosaur bones are so hard to get out of a nice sediment. Since then, Earth’s mostly avoided NEOs at parties, though some dustups between these frenemys do occur every once in a while.
And Earth does have to deal with copycats every once in a while. For about 100 years, the little asteroid 2023 HO3 has been following Earth, dancing around the planet while it goes around the Sun—but not actually orbiting, even though it’s circling around our planet at a constant rate. This week, scientists confirmed that HO3 really is just an asteroid orbiting the Sun who happens to circle the Earth in a moon-like fashion, and not space junk.
Speaking of space junk, the Earth has that in abundance. Earth’s humans keep promising to clean it up, but don’t hold your breath. Earth keeps pulling some of that space junk down into the atmosphere, but then, instead of being grateful, they’re all worried that a space station will smash into them. Kids, amiright?
Oh, and how could we forget the Moon. This giant, solid hunk of rock hasn’t left the Earth’s side since they bumped into each other around 4.5 billion years ago. Since then, they’ve been through everything together. The Moon takes care of watering the Earth’s coasts twice a day, moving around the Earth’s oceans, and Earth’s gravity keeps them together, though it does seem like they’ve been growing apart lately.
As for other relatives, Earth keeps in touch with a few on a more long-distance basis. Look, just because they all formed at the same time, that doesn’t mean that Earth is that close to Mars or Venus. They’ve all chosen to go different ways, ok? Mercury is busy sucking up to the Sun, Venus is hot-tempered all the time, and Mars and Earth…well, they used to be way more alike than they are now. And don’t even start on Jupiter, Saturn, Uranus and Neptune. They’ve all gotten so full of themselves out there, it’s like they’re too big for Earth anymore.
But that’s fine by Earth. It’s going to keep on doing its thing around the Sun, enjoying its visitors and hoping none of them outstay their welcome.
