Astronomers using ALMA have found large quantities of methanol in comet 3I/ATLAS, making it one of the most alcohol-rich ...

Interstellar objects move too fast and arrive too rarely for astronomy to rely on a single instrument or a single kind of light. When comet 3I/ATLAS was first reported on July 1, 2025, observatories ...

Astronomers studying the Kuiper Belt have detected a strange distortion that could point to an unknown planet lurking far beyond Neptune.

What can a piece of debris from another star tell astronomers about planets they may never see directly? The answer has changed dramatically since the first confirmed object from another star crossed ...

A visitor from another star system is creating excitement in the astronomy community. The comet 3I/ATLAS which was first spotted in July 2025 contains chemical clues that scientists can use to ...

Lead researcher Nathan Roth said the image shows the comet is “bursting with methanol in a way we just don’t usually see.” ...

Asteroids are some of the oldest objects in the solar system: leftovers from the chaotic time when planets were assembling ...

Debris flying immediately after DART collided with Dimorphos. (NASA DART team and LICIACube) In 2022, NASA made history, deliberately smashing a spacecraft into an asteroid to see if it could alter ...

The Rubin Observatory issues rapid alerts for changing celestial objects, enabling global scientists to detect supernovae, asteroids, and variable stars within minutes of observation.

Learn how ALMA observations revealed unusually high levels of methanol in interstellar comet 3I/ATLAS and what the molecule’s chemistry may reveal about how icy bodies form around other stars.

War Machine imagines a machine arriving from space. Real astronomy has detected interstellar visitors like ʻOumuamua, 2I/Borisov and 3I/ATLAS.

Earth has been around for 4.543 billion years. At numerous times during that long history, our planet has shared itself with the rest of the Solar System, particularly with our immediate neighbors. Sc ...
