The Latest Breaking News from NASA

Harvard's Avi Loeb challenges NASA's silence on 3I/ATLAS and the Local Interstellar Cloud. We reveal how increased cosmic ray penetration risks millions of air travellers.

New MeerKAT radio observations confirm that interstellar visitor 3I/ATLAS is not sending alien signals, and astronomers have identified the detected frequencies as natural cometary activity.

The Perseverance rover from NASA captured a strange boulder that does not seem to come from the planet.

Viral claims say interstellar comet 3I/ATLAS is sending alien signals. Scientists confirm: the 'signals' are just natural water chemistry.

"Space bank fraud" or a messy breakup?

ISRO's Mount Abu telescope captured an unprecedented, detailed view of 3I/ATLAS, only the third confirmed interstellar object.

The European Space Agency's (ESA) two satellites and several NASA spacecraft at and near Mars zoomed in on the comet as it passed the red planet just 29 million kilometres away last month.

The unique system features two rare Wolf-Rayet stars, and a supergiant companion that is interrupting the flow of the dust shells that the two Wolf-Rayet stars cast off.

Interstellar comet 3I/ATLAS, third visitor to our system, is pure ice—no technosignatures, says NASA on 19 November 2025. From July discovery to October Mars flyby, images reveal natural quirks

NASA released close-up images of interstellar comet 3I/Atlas, only the third known visitor from another star, after it passed near Mars. The closest the comet will come to Earth is 269 million kilometres in mid-December. Then it will hightail it back into interstellar space, never to return.

NASA has released stunning new images of interstellar comet 3I/ATLAS, revealing fresh details about its structure, its approach near Mars, and when it will pass closest to Earth. Here is everything we know from NASA's latest observations.
