Pluto's 'almost twin' dwarf planet Eris has a rocky core blanketed by an icy shell, which appears to be flexing slowly.

NASA will train two Indian astronauts, one of whom will fly to the ISS late next year, a space agency official announced this week.

NASA's endeavor to return humans to the moon during the Artemis 3 mission will likely be delayed because it is jeopardized by "multiple challenges" and an ambitious schedule.

A newfound, and impressively well-maintained, planetary system full of sub-Neptunes could reveal why our solar system lacks such a world.

NOIRLab says it's on track to halve its planet-warming emissions by the end of 2027.

A fresh analysis of moon rocks brought home during the Apollo missions suggests the presence of hydrogen, implying future astronauts could access water available right in lunar regolith.

A new supercomputer simulation reveals why spiral galaxies like our Milky Way are strikingly scarce in our pocket of the universe.

The first black hole ever imaged by humanity, M87*, appears to be losing energy like a spinning top decelerating over time.

India plans to bring moon samples back to Earth later in the 2020s with its Chandrayaan-4 mission.

Over 100 women scientists, including a handful of astronomers, have set sail to Antarctica.

Data from NASA's Kepler telescope shows why puffy sub-Neptunes are shrinking to rocky super-Earths.

The most energetic particles in the universe appear to emerge from sources within the Milky Way, our own home.

A laser gyroscope at an underground lab in Germany has detected the minute variations in Earth's rotation, an advance that may help scientists build better climate models.

Science data from a damaged balloon-borne telescope was salvaged, thanks to old-fashioned SD drives.

A new AI method can rapidly spot and map large icebergs in satellite images, helping scientists track changes to icebergs and their meltwater.

"If they're out there, this analysis lets us figure out where they could be living."

The rare dwarf galaxies were likely victims of galactic cannibalism.

Astronomers have found the most distant Milky Way look-alike we've seen the universe, challenging theoretical predictions of galaxy evolution.
