Astronauts' muscles atrophy in space, but we can identify the genes involved.

The microscopic creatures can withstand the harsh environment of outer space, making them ideal candidates to study new ways to protect astronauts.

"The fact that terrestrial microbes are the Earth's best colonizers means we can never completely discount terrestrial contamination."

Astronomers have discovered an exoplanet with a tail, like a gigantic comet. The planet, known as WASP-69b, is slowly evaporating in the radiation of its host star.

Scientists have come a step closer to understanding how collisionless shock waves – found throughout the universe – are able to accelerate particles to extreme speeds.

Only 10.2% of astrobiologists disagree with the claim that intelligent aliens likely exist.

"This has far-reaching implications."

Scientists find sterile ISS environment could explain rashes and cold sores and suggest adding microbes to stations

We're not alone.

NASA has thrown cold water on Harvard astrophysicist Avi Loeb's theory that interstellar visitor 3I/ATLAS was sent to us by an extraterrestrial civilization, a sobering, albeit unsurprising conclusion that could put the captivating hypothesis to rest once…

Nature Astronomy - This study uses observations from the DKI Solar Telescope to reveal that the Sun’s corona hosts small-scale torsional Alfvén waves. These twisting motions likely carry...

Some of the earliest images ever taken in the wake of massive star’s death give astronomers important clues about what triggers a supernova.

The moss was attached to the International Space Station, fully exposed to the harsh environment of the cosmos. Not only did the spores endure, but they could still reproduce after returning to Earth.

In the current issue of the journal Science, researchers determine the possible composition of Theia. The impactor’s composition allows conclusions about its place of origin. It is located in the inner Solar System, likely closer to the Sun than Earth. Lunar…

An essential amino acid that is mistakenly believed to cause drowsiness after eating turkey has been found in an asteroid for the first time, giving scientists clues to the origin of life on Earth.

We knew from prior analyses that a distant asteroid sampled in 2020 carried all but one of the molecules needed to kick-start life, and researchers have just found the missing ingredient: sugar

The scorching cloud of gas threaded between clusters of galaxies is five times hotter than current models predict, highlighting gaps in our models of galaxy cluster formation.

XRISM satellite allows UChicago scientists to directly detect turbulence driven by Perseus, M87 black holes
