Modern astronomy is giving us unprecedented views of the asteroids, comets, and other small bodies that litter our cosmic ...

The comet 3I/ATLAS, discovered on July 1, 2025, by the Asteroid Terrestrial-impact Last Alert System (ATLAS) in Hawaii, marks the third recorded interstellar object, following the discoveries of ...

Stargazers using telescopes should be able to see the object in the predawn sky beginning Nov. 11, according to EarthSky.

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.

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

New research from Rice University shows that Jupiter, the largest planet in our solar system, played a major role in shaping ...

What: Astronomers using JWST and ALMA have captured the earliest known stage of planet formation around the protostar ...

Astronomers say 3I/Atlas will be visible in parts of the US sky for a short time, giving viewers a unique look at a comet from beyond our solar system.

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.

When evaluating possible planets out of the thousands out there, explained Prof. Bean, scientists look for liquid water as a main guiding principle. “All life on Earth needs liquid water, no matter ...
