When an interstellar visitor slices through the solar system, astronomers usually have to make do with a fleeting, side-on ...

Interstellar object 3I/ATLAS is confirmed as a natural comet from beyond our solar system, posing no threat to Earth despite ...

The intricate whorls and striations of dust that drift between the stars have just been revealed in stupefying detail. In new images from JWST, we're finally seeing exquisite details of the flow and ...

Dust measurements of the interstellar object 3I/ATLAS provide constraints on its nucleus size, indicating a minimum radius of 1 km for a natural comet, as reported by Avi Loeb.

NASA’s Europa Clipper spacecraft has recorded important new observations of the interstellar comet 3I/ATLAS using its Southwest Research Institute-led Ultraviolet Spectrograph (UVS). In July, 3I/ATLAS ...

Astrophysicists are mapping a vast, hidden structure in space that appears to guide matter and radiation along a kind of ...

NASA’s Cassini spacecraft has detected the faint but distinct signature of dust coming from beyond our solar system. The research, led by a team of Cassini scientists primarily from Europe, is ...

I/ATLAS, the interstellar object discovered in 2025, reveals the estimated population, composition, and distribution of ...

From the outside, the little pebble looks like an ordinary rock — yellowish-brown, a little lumpy, and only aboutthree3 grams in mass. But beneath that brownish veneer, it’s studded with microscopic ...

Of the many different kinds of stars, asymptotic giant branch (AGB) stars, usually slightly larger and older than our own sun, are known producers of interstellar dust. Dusty AGBs are particularly ...

Understanding how dust grains form in interstellar gas could offer significant insights to astronomers and help materials scientists develop useful nanoparticles. Understanding how dust grains form in ...
