Interstellar Comet 3i Atlas Nasa

Dec 4, 2025nasa's hubble space telescope captured this image of interstellar comet 3i/atlas on july 21, 2025, when the comet was 277 million miles from earth. 1 day agointerstellar comet 3i/atlas (circled) is a bright dot with a tail passing through a field of stars in this video from nasa’s tess (transiting exoplanet survey satellite). The prefix "3i" designates it as the third confirmed interstellar object passing through the solar system, after 1i/ʻoumuamua and 2i/borisov.

[21] 3i/atlas is an active comet consisting of a solid icy nucleus. Nov 19, 2025nasa is in the midst of an unprecedented solar system-wide observation campaign, turning its spacecraft and space telescopes to follow comet 3i/atlas, the third known interstellar. Dec 8, 2025new 3i/atlas images from nasa and the european space agency suggest the interstellar comet is active as it approaches earth in december.

Nov 20, 2025nasa's highly anticipated comet 3i/atlas images have been released, with a space agency official shooting down alien rumors and stressing that the interstellar visitor is a comet.. Nov 30, 2025nasa reveals these new 4 things about 3i/atlas through the largest coordinated study of an interstellar comet, confirming its natural origin, ancient chemistry, and non-threatening trajectory. 1 day agothe discovery of interstellar comet 3i/atlas was one of the top astronomy stories of 2025.

Though the comet is now heading back to interstellar space, research into its properties and origins. 21 hours agointerstellar comet 3i/atlas has been seen moving across the night sky by one of nasa's top exoplanet-hunting missions. Tess (transiting exoplanet survey satellite) spotted comet.

Nov 19, 2025this image shows the halo of gas and dust, or coma, surrounding comet 3i/atlas, the third interstellar object ever detected by astronomers as it passes through our solar system.
