The mystery surrounding 3I/ATLAS has captured the imagination of many, from leading astronomers to pop culture A-listers like Kim Kardashian and tech mogul Elon Musk.

Elon Musk unveils his 'secret' theory that the interstellar object 3I/ATLAS could be 'aliens.' Discover the anomalies, why NASA is silent, and the debate over its 'artificial origin.'

Astrophysicist Dr. Avi Loeb called on NASA to share the other information it has on 3I/ATLAS with the scientific community.

Interstellar object 3I/ATLAS reaches its perihelion, prompting Harvard's Avi Loeb to suggest it's an 'alien mothership.' Learn about his 'acid test' theory and his warning that 3I/ATLAS could release 'mini-probes' toward Earth as 'Christmas gifts' on 19 December 2025.

ESA's ExoMars Trace Gas Orbiter was able to collect high-resolution imaging and spectroscopic data of the 3I/ATLAS comet.

Astronomers detect unexplained acceleration in interstellar object 3I/ATLAS as Avi Loeb suggests an artificial 'engine' can't yet be ruled out.

Physicist Brian Cox has confirmed that Comet 3I/ATLAS — an interstellar traveller predating our Sun — is a natural object composed of ice, dust, and carbon dioxide, and not of extraterrestrial design.

Interstellar comet 3I/ATLAS is briefly out of view as it travels around the sun this week, but researchers and amateur astronomers used spacecraft data to track its progress right up until perihelion.
