Exploring Titan's icy hydrocarbon cycle

Though wildly different in so many ways, Earth and Saturn's moon Titan have something important in common. Among all the objects in the solar system, they're the only two with liquids on their surfaces. There are parallels ...

Students design a mission to Venus on the cheap

Sometimes, the best way to learn how to do something is just to do it. That is especially true if you're learning to do something using a specific methodology. And in some cases, the outcome of your efforts is something that's ...

Studying Uranian moons using passive radar sounding

How can Uranus be used to indirectly study its moons and identify if they possess subsurface oceans? This is what a recent study presented at the 56th Lunar and Planetary Science Conference hopes to address as a team of scientists ...

How space law aims to regulate 'space junk' and protect Earth

While life on Earth has been dramatic enough lately, there's also been an unusual amount of news from space in the early months of 2025. So far, debris from SpaceX and Blue Origin rockets has landed in locations including ...

New distant warm Jupiter discovered with TESS

Using the Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected a new warm Jupiter exoplanet located more than 1,000 light years away. The newfound alien world, designated TOI-2005 ...

Sampling the plumes of Jupiter's volcano moon, Io

What can a sample return mission from Jupiter's volcanic moon, Io, teach scientists about planetary and satellite (moon) formation and evolution? This is what a recent study presented at the 56th Lunar and Planetary Science ...

How can we find cryovolcanoes on Europa?

In the 1970s, NASA's Voyager probes passed through Jupiter's system and snapped pictures of its largest moons, also known as the Galilean moons. These pictures and the data they gathered offered the first hints that a global ...

Fixing cracks in space bricks with bacteria

Researchers at the Indian Institute of Science (IISc) have developed a bacteria-based technique to repair bricks that can be used to build lunar habitats if they get damaged in the moon's harsh environment.

Video: Is space debris a crisis?

The European Space Agency's short documentary film "Space Debris: Is it a Crisis?" on the state of space debris premiered at the 9th European Conference on Space Debris on 1 April 2025.

Hubble's 20-year study of Uranus yields new atmospheric insights

The ice-giant planet Uranus, which travels around the sun tipped on its side, is a weird and mysterious world. Now, in an unprecedented study spanning two decades, researchers using NASA's Hubble Space Telescope have uncovered ...

NASA's dust shield successfully repels lunar regolith on moon

NASA's Electrodynamic Dust Shield (EDS) successfully demonstrated its ability to remove regolith, or lunar dust and dirt, from its various surfaces on the moon during Firefly Aerospace's Blue Ghost Mission 1, which concluded ...

Why we think Theia existed

The giant-impact hypothesis posits that billions of years ago a Mars-sized body named Theia collided with the early Earth.

A new theory explains how water first arrived on Earth

When Earth first formed, it was too hot to retain ice. This means all the water on our planet must have originated from extraterrestrial sources. Studies of ancient terrestrial rocks suggest liquid water existed on Earth ...
