Strange interstellar comet speculated to be alien spacecraft is older than Solar System
Interstellar comet 3I/ATLAS may be the oldest object ever seen in our solar system, dating back up to 12 billion years.
📍 Aftermath
The story of interstellar comet 3I/ATLAS, speculated to be an alien spacecraft, quieted with scientists suggesting it may be the oldest object ever seen in our solar system, estimated to be up to 12 billion years old. Researchers studied the comet's composition, with some detecting methane signatures and others finding no evidence of alien technology. The comet's origin and nature remain a topic of study, with NASA's Webb finding clues to its ancient, distant origin.

The brief
Interstellar comet 3I/ATLAS has captured scientific attention after observations suggest it formed up to 12 billion years ago, making it older than the Solar System. NASA's Webb telescope and the European Space Agency have identified clues regarding its ancient and distant origin.
The object is described as the coldest object ever seen in the solar system with a chemical composition unlike anything previously observed. Coverage from The Guardian, The Conversation, and Sci.News emphasizes the comet's extreme age.
While Yahoo reports on speculations that the object could be an alien spacecraft and Avi Loeb has questioned if methane signatures indicate life, Phys.org reports that radio scans found no evidence of alien technology. Future attention remains on the unique chemistry of 3I/ATLAS and the analysis of its composition to further understand its origins.
