Researchers rarely get a glimpse of an interstellar object up close like 3I-ATLAS, so they have jumped on the opportunity to learn about its composition, which can reveal how planet systems are made.

The comet could be older than our solar system. The comet is also distinct because nickel vapor was detected in the gas ...

About 4.6 billion years ago, the Solar System formed from a cloud of dust and gas collapsing in on itself due to gravity. The Sun, planets, and eventually Earth formed out of the cloud. But when did ...

On October 29, Comet 3I/ATLAS reached its closest point to the Sun. This point, known as perihelion, was around 210 million ...

A new planetary system is forming around the young star HOPS-315. Scientists observed the earliest stages of planet formation around another star. The process involves the cooling and solidifying of ...

The comet, officially detected on July 1, 2025, by the ATLAS (Asteroid Terrestrial-impact Last Alert System)telescope in Chile, has been confirmed to be travelling on a hyperbolic trajectory, meaning ...

Astronomers found an interstellar "tunnel" - a cosmic channel that connects our solar system to distant stars, according to a ...

Interstellar comets like 3I/ATLAS could serve as seeds for giant planet formation, potentially explaining how massive planets form around distant stars, according to BBC and Pfalzner’s research.

Discovery of oxygen raises new questions about how solar system formed. In this undated photo, Rosetta finds oxygen on comet 67P. ESA/Rosetta/NavCam – CC BY-SA IGO 3.0 — -- The European Space ...

Astronomers have identified 3I/ATLAS, an ancient, ice-rich interstellar comet potentially older than our solar system.

A rare interstellar visitor, comet 3I/ATLAS, is currently traversing our solar system, offering scientists a unique chance to ...
