NASA's Artemis II mission plans to fly around the moon and back this April. Four astronauts will board the mammoth Space Launch System (SLS) rocket for the test flight, spending 10 days off-Earth. They won't be touching down—this ...
If we're to find extraterrestrial life in the universe, astronomers have pinpointed the best places to look for it. They have identified just under 50 rocky worlds most likely to be habitable out of the more than 6,000 exoplanets ...
The Earth is under assault. Space rocks are constantly hurtling toward us, slamming into the atmosphere and often exploding into fireballs that both delight and alarm.
Even 200 years after asteroid 16 Psyche was discovered, astronomers continue to puzzle over its formation. Psyche is the 10th-most massive asteroid in the main belt between Mars and Jupiter, and the largest known metallic ...
Here is a problem that has been quietly gnawing at astronomers for decades. The standard approach to detecting life on other worlds involves scanning exoplanet atmospheres for oxygen, methane, and ozone, whose presence is ...
A thick layer of haze around the ultra-low-density planet Kepler-51d likely obscures not only the strange planet's composition, but also its origin, according to a new study. A team led by Penn State researchers used NASA's ...
Heat shields are designed to protect the surface and cargo of a spacecraft as it enters an atmosphere. Aerospace engineers in The Grainger College of Engineering at the University of Illinois Urbana-Champaign recently observed ...
"Follow the water" has been a guiding mantra of astrobiology, and even space exploration more generally, for decades. If you want to find life, it makes sense to look for the universal solvent that almost all types of life ...
Finding Earth-like planets orbiting sun-like stars and identifying signs of life such as oxygen or water is a major goal in astronomy and a key interest for the public. Addressing this challenge speaks directly to one of ...
Six planets are linking up in the sky at the end of February, and most will be visible to the naked eye.
