Harvard scientist Avi Loeb suggests comet 3I/ATLAS may be an alien vessel seeding life, after NASA's SPHEREx spacecraft detected unexplained methane and organic chemicals on board.

NASA is looking for new providers to supply low-gravity parabolic flights for spaceflight training and scientific research.

NASA's SPHEREx spacecraft has detected organic molecules on comet 3I/ATLAS, leading scientists to speculate it could be seeding life across the universe.

NASA and SpaceX have postponed the Crew-12 mission to the ISS from February 11 to no earlier than February 12 due to poor weather. The four-member international crew remains in quarantine as teams ...

A NASA spacecraft has discovered organic chemicals on 3I/ATLAS, which Harvard scientist Avi Loeb claims raises the possibility that the comet is an “interstellar gardener” seeding the universe with ...

It did not subside after the nearest approach of Comet 3I/ATLAS to the Sun; it became bright once more. The delay of that burst is significant, as it transforms a rapidly traveling alien interstellar ...

Why then should a comet increase, since it was already past the Sun and began its long departure? A NASA space telescope called SPHEREx observed interstellar comet 3I/ATLAS doing just that in December ...
