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.
This illustration shows the NASA spacecraft Wise (WISE) in Earth orbit. The WISE mission was completed in 2011, but in 2013 the spacecraft was reequipped to search for and study asteroids and other near-Earth objects (NEOs). The mission and spacecraft have been renamed NEOWISE. | Credits: NASA/JPL-Caltech
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.

Being very close companies, OPPO and OnePlus have decided to create a new partnership, with the latter being a pioneer in the market. It has become the representative of the best smartphones in the group, and this will be seen very soon.
Proving this, OnePlus has announced that it will have news soon. The following brand assets will be announced on February 7, 2023. We are talking about OnePlus 11 5G and Buds Pro 2.
In recent years, OnePlus has been showcasing new hardware in an attempt to find a new place in the market. The brand has not always seen its full potential, betting on mid-range or entry-level smartphones.
The situation is changing, and the novelty will go on sale in early 2023, February 7. It is on this day that the new OnePlus 11 5G will be presented with all the expected news. We definitely have the new Qualcomm Snapdragon 8 Gen 2 SoC here. There's still 16GB of storage left and 256GB of onboard storage.
It is expected that he will receive a 6.7-inch OLED display with a resolution of 1440p and a frequency of 120 Hz. In the field of photography, we will have an important change: a 50 MP main camera, a 48 MP ultra wide-angle camera and a 32 MP telephoto lens with 2x zoom. For selfies and video calls, you'll have a 16-megapixel camera.
The photography partnership with Hasselblad will continue with OnePlus for fine-tuning and some additions. This alliance has brought important results for the best smartphones of the brand, guaranteeing the best photos in any situation.
In addition to the new OnePlus 11 5G, another brand new feature is also expected to arrive at the event. We're talking about the Buds Pro 2, which are solidifying an audio commitment that's becoming more of a reality. The brand promises "rich stereo quality sound with crystal clear clarity".
Stays like this marked by the beginning of February, another important novelty will enter the market. OnePlus wants to reclaim its place, and that will be the brand's bet for years to come. OnePlus 11 5G and Buds Pro 2 take the first step in this direction.
