NASA releases impressive sky-mapping data

How many times have you found yourself lying in bed at night, gazing up at the stunning beauty of the night sky, filled with all its wonder and mystery, and suddenly thought: “Where’s my roof gone?” Hopefully never, as it would indicate that you have some serious issues with the structural integrity of your house.

Stand outside though, in a field far from the light pollution of towns and cities, and on a clear night you’ll be made to feel very small as you survey the awesome endlessness of the universe above you.

If you’re the kind of person inspired by such a sight, you’ll probably be interested to know that NASA has just released a veritable treasure trove of space-related information thanks to its Wide-field Infrared Survey Explorer mission – otherwise known as WISE.

A statement released on Thursday by NASA said: “Astronomers across the globe can now sift through hundreds of millions of galaxies, stars and asteroids collected in the first bundle of data from NASA’s Wide-field Infrared Survey Explorer (WISE) mission.”

The aim of the mission, which launched in December 2009, was to map the night sky in infrared light, hopefully revealing many space objects that can’t be seen in visible light. Many of the 2.7 million images are available for viewing online, and the plan is to have a complete map of the night sky on the Web by the spring of next year.

The images include those of distant galaxies and not-so-distant (though hopefully nothing to worry about) asteroids. While many parts of the night sky are already known to astronomers, the WISE mission has also revealed plenty of exciting new bits and bobs. These include 20 comets and more than 33,000 asteroids, which all happen to be floating about between Mars and Jupiter. Astronomers will continue to closely examine the incoming data in a bid to look for more new objects or any hitherto unknown oddities.

This exciting survey of the sky will have astronomers beside themselves with intergalactic glee, and with the data available online to all, the universe may be about to get a whole new audience.

NASA has selected two proposals to demonstrate technologies to improve science observations in deep space. The proposals could help NASA develop better models to predict space weather events that can affect astronauts and spacecraft, such as coronal mass ejections (CMEs). In this image, taken by the Solar and Heliospheric Observatory on Feb. 27, 2000, a CME is seen erupting from the Sun, which is hidden by the disk in the middle, so the fainter material around it can be seen.

Small satellites can be used for anything from collecting images and videos of Earth to exploring the Solar System, and as the technology improves, more and more uses will become possible. NASA has been searching for ideas to push ahead the capabilities of the hardware, and the agency has just announced two new projects to demonstrate the potential of small satellites.

NASA’s TESS satellite discovered three new planets right next-door
tess satelitte new planets nasa

NASA’s Transiting Exoplanet Survey Satellite, affectionately called TESS, discovered three new worlds during its latest exploration.
The exoplanets are the smallest, nearest known to date and orbit a star that’s just 73 light-years away, which is pretty much just around the corner in cosmic terms, NASA and MIT announced Monday.
The star furthermost away also looks like it potentially supports some forms of life. Researchers say that the top of the planet’s atmosphere is within a temperature range that could potentially host some kind of lifeform; however, the planet’s atmosphere might make that feat impossible. Researchers say that the atmosphere is likely quite dense, which creates a “heat trap” on the planet’s surface, That ultimately might make it too hot to host water or life, at least the type of living organisms we know about.
Scientists are calling the new planetary system TOI-270 (catchy, right?). All three planets in the system appear to be relatively close in size, unlike the planets in our solar system. One is being described as a rocky super-Earth of sorts, while the other two planets more closely resemble Neptune in our solar system, although they’re half its size.
Astronomers think that they’ll be able to learn more about planetary formation from the planets, specifically whether our planet and more rocky planets like Neptune (which is similar to the planets found), follow the same formation path.
TESS has been able to discover more than 20 different planets during its first year of observations, including a number of planets that are unlike the ones found here in our solar system.
Developed by MIT, TESS satellite began operations in July 2018 and has focused on the southern skies for its first year of work. It's expected to observe the Northern Hemisphere over the next year 0r so.
"The pace and productivity of TESS in its first year of operations has far exceeded our most optimistic hopes for the mission," said George Ricker of MIT, TESS's principal investigator. "In addition to finding a diverse set of exoplanets, TESS has discovered a treasure trove of astrophysical phenomena, including thousands of violently variable stellar objects."
Findings from the satellite's first year in operation were published Monday in the journal Nature Astronomy.

4000 Exoplanets

Thanks to major advances in technology, we’ve now managed to log the existence of more than 4,000 planets outside our solar system. That’s pretty darn impressive, especially when you consider that pre-1992 we couldn't identify any.
