An interstellar comet that originated outside our solar system has just made its closest pass to the sun, brightening dramatically and rapidly as it did so. The reason for the sudden extreme activity is currently puzzling scientists.

Astronomers are hustling to use interplanetary spacecraft to study the interstellar comet dubbed 3I/ATLAS while the sun is hiding it from Earth

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

This review contains spoilers for the Oct. 30 episode of “9-1-1.” Houston, we have no more problems. On Thursday’s episode of “9-1-1,” Athena (Angela Bassett) and Hen (Aisha Hinds) finally made it back to Earth after a four-episode arc that had them journeying to and from space.

DeGrasse Tyson, the world-renowned astrophysicist, spoke in front of 4,000 people at a summit in Erie in Oct. 29.

A scientist has recently posited that a mysterious interstellar object, potentially of extraterrestrial origin, appears to be dramatically decelerating, as if applying brakes. This intriguing hypothesis challenges previous assumptions about its trajectory through our solar system and sparks renewed debate among astronomers about its nature and implications for interstellar visitors.

Space watchers are questioning if NASA’s Juno spacecraft could have observed 3I/Atlas, but the agency’s silence leaves the mystery unsolved.

Does a video clip show a timelapse of interstellar comet 3I/ATLAS, captured by the Gemini North telescope in Hawaii, released on July 15, 2025, by NSF's NOIRLab and the University of Hawaii? No, that's not true: The authentic image
