First Radio Signal from 3I/ATLAS: OH Absorption Reveals Hydroxyl Molecules
Overview: A Possible Milestone in Interstellar Chemistry In a development that could reshape our understanding of interstellar chemistry, MeerKAT, the 64-dish radio telescope array operated by the South African Radio Astronomy Observatory, announced observations suggesting absorption lines from hydroxyl (OH) radicals in the light from the interstellar object 3I/ATLAS. While preliminary and awaiting independent verification,…

Ultraviolet fingerprint of water detected in interstellar comet 3I/ATLAS
Interstellar visitors and a long-awaited water signal For millions of years, a fragment of ice and dust drifted between the stars, a sealed bottle released into the cosmic ocean. This summer, that bottle washed ashore in our solar system as 3I/ATLAS, only the third known interstellar comet. In a landmark observation, Auburn University scientists used…
