Scientists believe 3I/ATLAS contains significant amounts of carbon dioxide, similar to comets formed in cold, distant star systems.

A Harvard astrophysicist who believes the Manhattan-sized comet hurtling towards Earth could possibly be fueled by alien technology has invited Kim Kardashian to join his research team — after she got a quick response from the federal government.

What: Comet 3I/ATLAS reached perihelion on October 30, 2025. This special SETI Live explored what scientists have learned about its origin, chemistry, and trajectory as it passes through our Solar System.

An astronomer has snapped comet 3I/ATLAS using the Lowell Observatory's powerful Discovery Telescope, as well as his own small telescope. The new photos are believed to be the first optical observations of the interstellar visitor since it disappeared behind the sun.

I/ATLAS was recorded by several objects as it made its close pass by the sun this week which resulted in the jarring measurements.

NASA is facing pressure from lawmakers and scientists to release data on 3I/ATLAS after the agency publicly reassured Kim Kardashian.

The interstellar comet 3I/ATLAS has a thick irradiated crust that no longer resembles its home star system, simulations and James Webb Space Telescope observations have found.

Besides the media from the HiRISE cam, the Republican has also requested all the available content on the comet from other instruments, including “the Parker Solar Probe or other active observatories under NASA's purview, aside from the Hubble and James Webb Space Telescopes.”
