Astronomers on Wednesday confirmed the discovery of an interstellar object racing through our Solar System - only the third ever spotted, though scientists suspect many more may slip past unnoticed. The visitor from the stars, designated 3I/Atlas, is likely the largest yet detected, and has been classified as a comet, or cosmic snowball. "It looks kind of fuzzy," Peter Veres, an astrono

Why is Mars barren and uninhabitable, while life has always thrived here on our relatively similar planet Earth? A discovery made by a NASA rover has offered a clue for this mystery, new research said Wednesday, suggesting that while rivers once sporadically flowed on Mars, it was doomed to mostly be a desert planet. Mars is thought to currently have all the necessary ingredients for li

Using data from ESA’s SMOS satellite, scientists have revealed a surprising shift in the Southern Ocean – surface waters around Antarctica are growing saltier, even as sea ice is diminishing rapidly. This finding defies the norm because melting ice typically freshens ocean surface water.

The implications are far-reaching as changes in this remote region can disrupt global ocean currents, affect climate patterns, and alter ecosystems far beyond the Antarctic.

Astronomers have confirmed the discovery of a rare celestial visitor: a comet from beyond our Solar System.

Officially named 3I/ATLAS, this newly identified interstellar object is only the third of its kind ever observed, following the famous 1I/ʻOumuamua in 2017 and 2I/Borisov in 2019.
