Data from 2023 soured hopes that a nearby exoplanet had a habitable atmosphere. That disappointment might have been premature.
We focus on planets as habitats for life but what if other environments, even ones maintained by organisms themselves, can also provide these necessities?
A few years ago, a radio telescope operating out of the desert of Western Australia observed something very weird.
In case dark matter didn't seem mysterious enough, a new study proposes that it could have arisen before the Big Bang.
A new analysis of the eruption rates of 56,400 Sun-like stars has estimated that the Sun's superflare rate is at the low end of that scale – once every 100 years.
Astronomers made a photo of a colossal belch – a gamma-ray eruption from one of the powerful jets of plasma launched from the black hole's poles as it feeds.
The review takes a close look the final flight of the agency’s Ingenuity Mars Helicopter, which was the first aircraft to fly on another world.
Using NASA’s Chandra X-ray Observatory, astronomers have found an unusual mark from a giant black hole’s powerful jet striking an unidentified object in its path.
For the first time, NASA's James Webb Space Telescope has detected and "weighed" a galaxy that not only existed around 600 million years after the big bang, but is also similar to what our Milky Way.
An object up to dozens of times the mass of Jupiter flying through our solar system may have disrupted planetary orbits.
Scientists know the Universe is expanding because they can track other galaxies as they move away from ours. They define expansion using the rate that other galaxies move away from us.
Dark comets are objects that looks like asteroids but acts like comets. Now, new research has doubled the number of known dark comets and grouped them into two distinct populations.
Their orbit periodically takes them through a cloud of gas, triggering flares.
Astrophysicists find the birth sites of gigantic elliptical galaxies which they say gives new clues about how they were formed. The galaxies look like bulging footballs and how they were created remains a mystery to scientists -- until now.
Contradicting the results of several recent studies, the new findings reopen the case that Jupiter-family comets like 67P/Churyumov-Gerasimenko could have helped deliver water to Earth.
