Nature Astronomy, Published online: 10 July 2026; doi:10.1038/s41550-026-02913-7Subtle orbital shifts prompted deep imaging of near-Earth object 1998 SH2, which uncovered a weak tail and confirmed cometary activity. The result indicates that more near-Earth objects currently classified as asteroids may also exhibit hidden low-level activity.

ESA and JAXA have finalized an agreement to collaborate on a mission to study the asteroid Apophis during its close flyby of Earth in 2029.

As the first asteroid deflection test, NASA's successfully hit asteroid Dimorphos (secondary of the binary asteroid 65803 Didymos) with the DART kinetic impactor on September 26, 2022. To fully charac...

Interstellar objects provide the only directly observable samples of icy planetesimals formed around other stars, and can therefore provide insight into the diversity of physical and chemical conditio...

NASA’s DART mission changed the orbit of the Didymos system, revealing insights into the physical traits of its two asteroids.

Only three interstellar objects have ever been spotted. Here’s what we know about them and why they’re so cool.

A delay in one European Space Agency mission is creating an opportunity for an earlier, and more capable, launch for another ESA spacecraft.

The largest contributions in the history of the European Space Agency, €22.1 bn, have been approved at its Council meeting at Ministerial level in Bremen, ...
