New research may have identified a culprit molecule that caused Venus, often described as Earth's twin, to lose its water and become an inhospitable hellscape.

Thanks to XMM-Newton, astronomers may know the powerful event that gave rise to the Cloverleaf odd radio circle.

Scientists think they've uncovered a cosmic "glitch" in gravity that could require a revision in Einstein's theory of general relativity.

Reports of life signs detected in the atmosphere of the potential ocean world K2-18 b may have been premature.

Citizen scientists have spotted a truly remarkable planet in a binary system's habitable zone. They gave a Harry Potter-inspired nickname.

It may have fewer pixels than the screen of a 1989 Game Boy, but the Resolve device on the XRISM space telescope will broaden our view of the cosmos.

Both the Hubble Telescope and TESS exoplanet hunter went into safe mode on April 23. Hubble is back on, but TESS remains off.

WASP-12b is a planet on a date with a fiery destiny, doomed to plunge into its sun-like star. Scientists may finally know why some hot Jupiters eventually death spiral into their stars.

The JWST has performed a weather report for a distant hot Jupiter exoplanet, finding winds three times as fast as a jet fighter, clouds made of rock and temperatures hot enough to melt lead.

Read the latest news about NASA's James Webb Space Telescope.

An erupting star system in Orion has finally provided an answer to the mystery of how stars fed for over 100 years, something that has puzzled astronomers for almost as long.

Samples of asteroid Ryugu, collected by the Hayabusa2 spacecraft, have revealed the impact solar winds and tiny space rocks have had on the asteroid itself.

NASA's exoplanet hunter TESS may have detected its first free-floating planet with a little help from Einstein.

Gamma-ray bursts are the universe's most powerful explosions, generating more energy in seconds than the sun will in billions of years — and scientists are slowly learning more about these eruptions.

The James Webb Telescope has zoomed in on the Horsehead Nebula, capturing slices of this stunning star-forming region close to Earth in an entirely new light.

A new model of Enceladus "tiger stripe" fractures and their connection with the moon of Saturn's ice geysers and subsurface oceans could have implications for its ability to support life.

Astronomers finally know why giant binary stars born from the same collapsing cloud of gas and dust can be "non-identical twins" with different characteristics and planetary systems.

The Hubble Space Telescope entered safe mode and stopped conducting science on April 23 when one of its three remaining gyroscopes sent faulty readings back to Earth.

Supermassive black holes may create conditions akin to "cosmic intersections with failed traffic lights" that make collisions between smaller stellar-mass black holes inevitable.

Superradiant atoms could help us measure time more precisely than ever before, a theory developed with the aid of the great-grandson of the "father of the atom," Niels Bohr.

"This means we will have to adjust our views on early galaxy evolution."

When it arrives at Jupiter and the planet's moons in 2031, the JUICE spacecraft will use ice-penetrating radar to see beneath determine habitability.

NASA's Fermi Space Telescope has failed to see gamma rays from a nearby supernova that should be created when it generates the high-energy cosmic rays that bombard Earth in their trillions.

Some stars erupt with 'superflares' 10,000 times as powerful as solar flares from the sun. A team of "stellar detectives" are on the case and may now know why some stars are so violent.

Neutron stars could act as gravitational traps for dark matter, forcing these mysterious particles to collide, annihilate and warm up otherwise cold dead stars.
