NASA’s SPHEREx space telescope has observed interstellar comet 3I/ATLAS flaring dramatically months after its closest pass by ...

INSIDE THIS REPORT The discovery did not arrive with spectacle. It arrived in spectral lines—quiet, technical, and unmistakable. NASA’s SPHEREx telescope has now detected organic molecules streaming ...

NASA's new SPHEREx observatory has released its first all-sky cosmic map. This map uses 102 infrared wavelengths to reveal the universe in unprecedented detail. Scientists can now study cosmic ...

An interstellar comet racing through our solar system released methanol, methane and cyanide, NASA says. Could these life linked molecules hint at how worlds across the cosmos are seeded?

Comets usually fade quietly once they swing past the Sun. Interstellar comet 3I/ATLAS did not follow the same path. Instead, ...

NASA's SPHEREx space telescope detected organic molecules coming off comet 3I/ATLAS as the interstellar visitor made its closest approach to Earth in December.

Comet 3I/ATLAS was full-on erupting into space in December 2025, after its close flyby of the sun, causing it to ...

NASA’s SPHEREx space telescope mission viewed 3I/ATLAS in December 2025, when researchers believed the brightening occurred due to a phenomenon associated with comets as they vent water, carbon ...

SPHEREx detected a mix of molecules streaming off the comet, including water ice, carbon dioxide, and rocky material.

NASA's Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx) was built for ...

NASA's SPHEREx telescope captured a significant outburst from interstellar comet 3I/ATLAS, revealing unique chemical insights into extraterrestrial material.
