NASA shows 12 years of changes in the universe in 2 minutes (video)

NASA’s NEOWISE (Near-Earth Object Wide Field Infrared Survey Explorer) spacecraft orbits the Sun every six months. On his journey, he receives images of the universe in all directions. Together, these images form a map of the entire sky.

The most incredible thing about these images is that the spacecraft is capable of capturing the location and brightness of hundreds of millions of objects. There is a fantastic video that we will show you.

NASA Film Shows Changes in the Universe... Million-Year-Old Glows

Operating Systems scientists used 18 maps of the entire sky compiled by the space mission (the 19th and 20th will be released in March 2023) and created what is essentially a film about the sky, revealing changes spanning a decade.

Each map is a huge resource for astronomers, but when viewed sequentially, it serves as an even more important resource for trying to better understand the universe. Map comparisons can reveal distant objects that have changed position or brightness over time, known as time-domain astronomy.

If you go outside and look at the night sky, it may seem that nothing is changing, but it is not. Stars flare and explode. Asteroids pass us and shimmer. Black holes tear stars apart. The universe is a really busy and active place.

This is Amy Mainzer chief investigator for NEOVIZ at the University of Arizona in Tucson, USA.

NEOWISE was originally a data processing project to obtain data on detected asteroids and their characteristics from WISE, an observatory launched in 2009 that was tasked with analyzing the entire sky to search for and study objects outside our solar system.

The spacecraft used cryogenically cooled detectors, making them sensitive to infrared light.

Mission WISE, dying, refuses to die

Infrared light, invisible to the human eye, is emitted by many objects in space, including cool nearby stars and some of the brightest galaxies in the universe.

Mission WISE ended in 2011 after running out of onboard coolant needed for some infrared observations., but the spacecraft and some of its infrared detectors were still operational. Therefore, in 2013, NASA redirected it to track asteroids and other near-Earth objects. Both the mission and the spacecraft were given a new name: NEOWISE.

Despite the changes, the infrared telescope continues to scan the sky every six months, and astronomers continue to use the data to study objects outside our solar system.

For example, in 2020, scientists released the second iteration of a project called CatWISE: an object catalog of 12 all-sky maps from NEOWISE. Researchers use the catalog to study brown dwarfs, a collection of objects found across the galaxy that lurk in the darkness near our sun. Although they form like stars, brown dwarfs do not accumulate enough mass to initiate nuclear fusion, the process that makes stars shine.

Because of their proximity to Earth, nearby brown dwarfs move faster across the sky than more distant stars, which move at the same speed. So one way to identify brown dwarfs among the billions of objects in the catalog is to look for moving objects. A CatWISE spin-off project called Backyard Worlds: Planet 9 invites citizen scientists to examine the NEOWISE data for moving objects that may have been missed by computer searches.

NASA WISE "discovered" 200 brown dwarfs

With two original WISE full sky maps, Scientists have found about 200 brown dwarfs within 65 light-years of our Sun.. Additional maps revealed 60 more and doubled the number of known Y dwarfs, the coldest type of brown dwarf. Compared to warmer brown dwarfs, Y dwarfs may have a weirder history in terms of how they formed and when they formed.

These discoveries help illuminate the collection of objects in our solar region. And a more complete count of brown dwarfs near the Sun tells scientists how efficient star formation is in our Galaxy and how early it started.

Watching the sky change over more than a decade has also contributed to the study of how stars form. NEOWISE can peer into the dusty mantles surrounding protostars, or into balls of hot gas en route to becoming stars. Over the years, protostars twinkle and flare, accumulating mass from the dust clouds that surround them. Scientists are monitoring nearly 1,000 protostars long-term with NEOWISE to gain insight into the early stages of star formation.

The NEOWISE data also improved our understanding of black holes. pushing The original WISE discovered millions of supermassive black holes at the center of distant galaxies. In a recent study, scientists used NEOWISE data and a technique called echo mapping to measure the size of disks of hot, glowing gas surrounding distant black holes that are too small and far away for telescopes to see.

Most crypto companies will 'fail' after years of industrial Ponzi schemes: Palantir co-founder

More crypto companies will fall Bankruptcy Ponzi SchemeBut cryptocurrency will remain an important tool for the global exchange of funds, one venture capitalist told Fox News.

“In general, I think most things are doomed to failure,” said Joe Lonsdale, investor and co-founder of software company Palantir. The various lenders of cryptocurrencies, crypto tokens, and other parts of the ecosystem were “a Ponzi scheme and made absolutely no sense.”

“This is what you expect in any situation where something goes wrong,” he added.

In recent years, according to Lonsdale, “crypto projects have been valued not on the basis of cash flow, not on the basis of value creation in the economy, but on the basis of what people are going to pay for it.”

According to Lonsdale, some of the companies that filed for bankruptcy “were heavily corrupt”, though he named only FTX. “There is a good chunk of crypto in the long run, but most of what we have seen in crypto over the past three, four, five years has been a speculative bubble driven by cheap money and a lot of these Ponzi schemes.”

Despite recent upheavals cryptocurrency marketsCryptography-based technologies will continue to expand their capabilities, Lonsdale said. Lonsdale said Blockchain technology used in cryptocurrencies allows money to be transferred online without the need for traditional government or banking infrastructure, opening up an important new way to move money around the world.

“It makes sense to have more decentralized power and have something like bitcoin,” he said. “He helped people survive money from RussiaFrom Venezuela, from China.

“It gives more freedom to the financial system than really bad governments,” Lonsdale continued.

Adobe Fresco is now available in the Microsoft Store

Adobe Fresco is now officially available for download from the Microsoft Store, giving users a new way to access the Adobe digital painting app. Previously, the app was only available through the Adobe website. The store version is still provided and managed by Adobe, which means it is not actually hosted on the Microsoft platform. Either way, it was an easier way to access it.

Adobe Fresco is now available in the Microsoft Store

Fresco is one of Adobe’s most advanced creative tools, a digital drawing and painting application designed primarily for touch devices. It’s actually available on iPad and iPhone, but not on macOS. So it’s really designed for touch screens, even on Windows 11.

According to Adobe, Fresco has the largest and “most advanced selection of brushes” in the world, thousands of which are available in the Adobe Library. The purpose of this app is to mimic real life as much as possible. So when you use watercolor for example, you will see the colors blend in real time. You can also paint in oils and use many other tools to create your desired piece of art. Fresco supports layers, layer masks and other features you would expect from a graphic design tool. Because it’s part of the Adobe Creative Cloud, it’s also linked to assets from Photoshop or Illustrator.

Meanwhile, in addition to being able to share finished work, Fresco has built-in real-time streaming capabilities to make it easier for you to share your knowledge with others. Plus, you can export a time-lapse of your drawing and painting process when you’re done.

However, this version of Fresco lacks support for ARM-based devices such as the Surface Pro 9 with 5G or the Surface Pro X. This is what Adobe originally promised back in 2019 when Surface Pro X arrived. Three years later, he still hasn’t done it. Recently at the Snapdragon Summit, the company confirmed its intention to release an ARM version in 2023, so let’s hope it won’t be long.

xrOS: óculos de realidade aumentada da Apple terão novo sistema operacional

fans Apple waiting for the launch of the headset augmented reality (RA) companies at the beginning of 2023 – in January, to be more precise; however, the change was revealed in an interesting detail. The tech giant announced that the hardware operating system will be called “realityOS‘, however the name will be xroOS, according to the latest reports. The effort invested by the pros has increased in recent months, indicating that the launch of the device is close.

According to recent announcements, Apple’s operating system for the augmented reality headset will be called xrOS.

One suggested reason for the name change is that the “xrOS” designation for international consumers will make it easier to identify the type of content that will be projected with the AR headset. Letters”XR” is an abbreviation for “andXcourted Rreality”, indicating the availability of resources possible with augmented reality, in free translation and interpretation.

Apple’s augmented reality glasses still don’t have a set release date

That is: based on the assumption that the equipment will play mixed content such as RA, as well as virtual reality resources (van), the consumer will be informed about what can be found easily. On the one hand, part of the intended experience is to combine real-time graphical information with the use of the environment and, at the same time, immerse the person in a differentiated experience with aspects of virtual reality, with a headset display.

The equipment will be able to play mixed content, such as AR itself, as well as virtual reality (VR) resources.

Because these approaches require powerful resources to run, despite being portable and lightweight, the hardware must also be powerful. Users will have access to new applications designed to provide unique experiences using product features. A wide range of options is expected, such as cards, messengers adapted for the mentioned technologies and much more.

Unfortunately, while the news was positive for those concerned, sources weren’t able to pinpoint the launch window. Therefore, many expect the presentation to take place in early 2023. Expectations are recommended to be controlled, because this is Apple’s first attempt in the segment, and unforeseen events may occur.
