JAXA is leading an international mission to reach Mars’ Phobos moon and bring soil back to Earth. If successful, it could unlock new clues about the history of the solar system.

Though scaled back from initial plans of landing, the voyage will serve as a dress rehearsal for when humans return to the moon’s surface.

The new image isn’t just stunning—it may also provide clues about how this star survived its own explosion.

The data drop includes photographs, audio, video, and astronauts’ notes that will be used to study the moon and prepare for future human missions.

“Detecting a neutrino is like looking for a needle in a haystack,” says Juan Carlos Díaz Vélez, who breaks down why researchers are looking for the cosmic particles under the Antarctic ice.

Under 1 million years old, “Elias 2-24b” is now the youngest exoplanet ever observed, and it may force researchers to reevaluate theories about how planets are formed.

Startup Star Catcher is launching a system that, if successful, would be the first time energy has been beamed between two separate spacecraft.

A competition between the gravity of the inner core and other forces in the mantle is altering the Earth’s rotation.

One of the great mysteries in astronomy has been why Venus has no moon. Now a new theory provides a simple answer: It might have been eaten.

No, it’s not aliens, but a phenomenon caused by magnetic activity that astronomers have never before been able to pin on a specific planet.
