Testing Heat Shields for Different Atmospheres
Testing is one of the unsung steps in the engineering process. Talk to any product development engineer, and they will tell you how big of a milestone passing “V&V” – or verification and validation – testing is. Testing is even more critical when you work on equipment meant for the harsh space environment. It is also more challenging to mimic those harsh environments on Earth. Luckily for some of NASA’s more critical upcoming missions, another government agency has a unique test lab to help V&V with some of its most critical components – their heat shields.
This Early Impact Devastated Life then Gave it a Boost
Most of us know about the impact that wiped out the dinosaurs about 66 million years ago. It’s a scientific fact that’s entered mainstream knowledge, maybe because so many of us shared a fascination with dinosaurs as children. However, it’s not the only catastrophic impact that shaped life on Earth.
See the 'comet of the century' light up the night sky in breathtaking photos
Comet A3 Tsuchinshan-ATLAS proved to be photogenic as it lit up the early autumn skies of the Northern Hemisphere this month.
Supergiant star Betelgeuse may have a 'Betelbuddy'
The supergiant star Betelgeuse may have a companion star that pushes light-blocking dust out of the way, causing the irregular changes observed in the star's brightness.
Scientists have dated the moon's oldest, and largest, impact site
The moon has been bombarded by asteroids and comets for more than 4.32 billion years.
China’s ‘Thousand Sails’ Joins Starlink as the Latest Mega-Satellite Constellation in Orbit
With ‘Thousand Sails,’ China joins the race to fill up Low Earth Orbit with mega-satellite constellations.
How does the Cosmic Web connect Taylor Swift and the last line of your 'celestial address?'
A map of gravity wells or "basins of attraction" in the local universe may resemble a Taylor Swift outfit, but they define the largest structure in the universe, the last line of your cosmic address.

Life on Earth Needed “Unmelted Asteroids”
The word “volatile” is commonly used in the space exploration community, but it has a different meaning than when used otherwise. In space exploration, volatiles are defined as the six most common elements in living organisms, plus water. Earth had enough volatiles for life to start here, but it might not have been that way. Researchers from the University of Cambridge and Imperial College London now think they have a reason why Earth received as many volatiles as it did – and thereby allowed it to develop life in the first place.
Comet Tsuchinshan-ATLAS is a Halloween visitor from the spooky Oort Cloud − the invisible bubble that's home to countless space objects
The cloud is basically a gigantic reservoir that may hold billions of icy celestial bodies. Two of those bodies will pass by Earth in the days leading up to Halloween.
Prime Video series 'Secret Level' unveils stellar vocal cast: Kevin Hart, Keanu Reeves and more
The jaw-dropping voice cast for "Secret Level," Prime Video's new anthology series, was announced at New York Comic Con on Oct. 19.
NASA peers into the blistering hot plasma swirling around 12 black holes
Stellar-mass and supermassive black hole coronas have some similarities, and this is great news for black hole physicists.
The Pluto problem: Is it time to rethink our definition of a planet?
In 2006, the International Astronomical Union (IAU) famously demoted Pluto to a dwarf planet. Things have been a bit of a mess since then — so is it time to redefine the planet?
'NASA at a crossroads:' Budget woes, aging infrastructure and hard choices ahead
The next few years are likely to be pivotal ones for NASA, according to a hard-hitting report by the U.S. National Academies of Sciences, Engineering and Medicine.
What happens when black holes merge?
Black hole mergers are beautiful — and some of the most violent events in the cosmos. Here's how the process unfolds.
Dark Matter Has a Firm Grip on These Galaxies
The elliptical galaxy NGC 1270 lies about 240 million light-years away. But it’s not alone. It’s part of the Perseus Cluster (Abell 426), the brightest X-ray object in the sky and one of the most massive objects in the Universe.

NASA Achieves Impressive Bandwidth with its New Laser Communications System
Ships passing in the night used Morse code sent with lanterns and shutters to communicate. That same basic principle has allowed NASA to communicate with Psyche, its mission to a metal-rich asteroid in the main belt. However, the “light” was a version of heat, and instead of being able to see each other, Psyche is 240 million miles away from Earth. Oh, and the upload rate of the data it sent is still better than old dial-up internet connections that were prevalent not so long ago.
Most of Earth's meteorites may have come from the same 3 spots
