NASA has suddenly decided to direct all its telescopes toward 3I/ATLAS.

3I/ATLAS has been classified as an interstellar comet, designated C/2025 N1. Its unbound path suggests that it is not gravitationally bound to our Solar System, making its visit a rare occurrence. The object has stirred speculation about the possibility of extraterrestrial life and has even been linked to various cultural prophecies regarding alien contact in…

The “Wow! Signal” was detected on August 15, 1977 as a strong narrowband radio signal by Ohio State University’s Big Ear radio telescope. Its origin was inferred to be extraterrestrial. The latest natural explanation (accessible here) hypothesized that the “Wow! Signal” was caused by a sudden brightening of the hydrogen line emitted from an interstellar…

the interstellar object 3I/ATLAS is anomalously massive and large! In a new paper (accessible here) shows the data on the motion of 3I/ATLAS — as compiled by the Minor Planet Center between May 15 and September 23, 2025, to set an upper limit on the deviation of 3I/ATLAS from a trajectory sculpted by gravity alone.

A new report from the UVES spectrograph of the European Very Large Telescope in Chile provides data on the anomalous abundance of nickel and iron in the plume of gas surrounding the interstellar object 3I/ATLAS. To read the full article >>

As it turns out, a recent coronal mass ejection (CME) is heading directly toward the interstellar comet ATLAS! And amateur astronomers are now asking: how often does something like this happen? Almost never — which makes it well worth watching. According to NASA’s forecast model, the CME that erupted on September 19 is expected to…
