2 new studies suggest the subsurface ocean on Jupiter's moon Europa may not be as habitable as previously thought, due to a geologically inactive seafloor.
A study from an international team of scientists shows it might be possible to detect microscopic life in ice grains in plumes of ocean moons like Enceladus.
NASA's Hubble Space Telescope has sent back new images of Jupiter's stormy weather. Hubble monitors the atmospheres of all the giant planets every year.
NASA's Webb Space Telescope has discovered a possible hycean world, with a deep hydrogen atmosphere and a global water ocean. Or is this world too hot?
The Voyager 1 spacecraft started sending gibberish back to Earth in November. Now engineers have sent it a "poke" and received a message they can decipher.
Activity on the sun affects Earth's magnetic field. It can cause geomagnetic storms and can create beautiful auroras. Are these solar storms dangerous?
A newly found giant volcano on Mars erupted in "modern times" and could erupt again. It's the site of glacier ice, with implications for life and exploration.
Researchers at Cornell University say that scientists can determine the water temperature of ocean moons by measuring the thickness of their ice shells.
