Siddharth Patel has been watching the sky since the age of five. Fresh off two possible asteroid discoveries, he's taking a big step toward his astronaut dream.

While interstellar comet 3I/ATLAS will not come near our planet, future ones may. A new campaign seeks to improve orbit predictions.

A new space debris removal project, ALBATOR, plans to tackle the growing debris problem in orbit.

Comet 3I/ATLAS is warming up as it approaches the sun, causing a jet to emerge. The jet is visible in a dramatic new image.

A scientist spotted an asteroid hiding in the sun's glare that orbits the sun in just 128 days, making it the second fastest known asteroid in the solar system.

PLATO powered up and extended its solar panels as the exoplanet-hunting spacecraft readies for launch as soon as December.

A small asteroid, called 2025 TP5, safely flew by our planet on Oct. 15 at about a quarter of the distance to the moon.

NASA launched an exoplanet-hunting experiment Oct. 1 despite the government shutdown. After the mission's end on Oct. 2, news reports got a little confused.

Four proposed sun-gazing spacecraft, working together, could help speed up space weather warnings by 40%, a new study suggests.

The names of human ancestors are now on an asteroid map.

Ben Bailey has 2,000 hours of flight time, including with high-profile military helicopters. The NASA astronaut candidate may be able to leverage that experience for moon landings.

A new study suggests that a group of cells, key for the health of blood and the immune system, are vulnerable to aging-like processes after spending time on the ISS.

NASA is working on finding landing sites for future moon astronauts. Part of the work includes thinking about how to prepare for eventual Mars missions with astronauts.

If we slam an impactor into an asteroid in exactly the wrong spot, the space rock may pass through a "gravitational keyhole" that brings it to Earth.

As part of the Artemis 2 astronaut moon mission launching no earlier than 2026, NASA is asking volunteers to test alternative forms of deep-space tracking.

Conducting a flyby mission to an interstellar object visiting our solar system is "feasible and affordable," a new study finds. But orbiting such an interloper is a different story.
