NASA is ‘all eyes’ on the ice giants … and you can help!

NASA's New Horizons spacecraft and Hubble Space Telescope will turn their eyes to the ice giants - Uranus and Neptune - in September. And NASA wants your help!

Are the TRAPPIST-1 exoplanets habitable, or not?

In a new study, astronomers say that at least some of the 7 Earth-sized TRAPPIST-1 exoplanets could be habitable now, even if they didn't start out that way.

Surf’s up! Waves on heartbeat star are as tall as 3 suns

Giant waves on heartbeat star MACHO 80.7443.1718 are as tall as 3 suns, astronomers say. They give a new meaning to the phrase "surf's up!"

Ancient ‘honeycomb’ mud on Mars boosts chances for life

NASA's Curiosity rover has discovered ancient honeycomb-patterned mud on Mars. The now bone-dry mud is evidence of cyclic wet-dry periods in Mars' past.

The centuries-long effects of Saturn storms

A team of researchers has found that huge Saturn storms - megastorms much larger than hurricanes on Earth - can last for hundreds of years at a time.

Powerful winds from cool stars can threaten exoplanets

A new study from researchers in Germany shows that stellar winds from cool stars with strong magnetic fields can be more powerful than ones from hotter stars.

Webb telescope provides unique view of 2 Jupiter moons

NASA's Webb telescope has captured spectroscopic and infrared views of 2 of Jupiter's moons, Ganymede and Io, providing new insights into these distant worlds.

Was Mars’ Olympus Mons volcano once an island?

Scientists in France have found new evidence that the largest volcano on Mars, Olympus Mons, was once a volcanic island surrounded by an ancient northern ocean.

Rogue planets by the trillions in our Milky Way?

A new study predicts that NASA's upcoming Roman space telescope will find 400 Earth-mass rogue planets. These worlds drift freely in space, unbound to any star.

Volcanism on Venus fueled by powerful ancient impacts

A new study says that high-speed impacts fueled early volcanism on Venus, explaining why Venus' surface is geologically young despite a lack of plate tectonics.
