A new comet approaching from sunward could make a fine dusk appearance in October. There was chatter on the boards this past Friday September 12th, about a comet seen in the Solar Wind Anisotropies (SWAN) images near the Sun. Tentatively named SWAN25B and now formally designated as C/2025 R2 SWAN, this comet could put on a brief show in late September into October if it holds up.

It’s rather strange to think about catching a planet in the act of being born given that the process takes millions of years but for the first time, astronomers have done just that! The evidence reveals a planet actively forming and feeding from its surrounding disk of gas and dust. The discovery of hydrogen emission from the protoplanet offers a new glimpse into the violent stages of planetary formation, revealing processes that shaped our own Solar System billions of years ago.

ISOs like Comet 3I/ATLAS are fascinating yet fleeting visitors from distant solar systems. New research suggests that when captured by a young solar system that's still forming planets, these objects could act as planetary seeds for the formation of planets.

Can a planet that lacks plate tectonics and has very little carbon dioxide support life? Maybe. Can it support life long enough for a technological civilization to arise? New research says no.

According to every experiment, the constants of nature appear to be constant.

A bizarre new type of object could solve one of astronomy's most puzzling mysteries. The James Webb Space Telescope spotted some “little red dots” and until now, it’s been thought they were galaxies. Now, a team of astronomers have come up with an alternative theory, supermassive black holes wrapped up in a thick envelope of gas and they are calling them ‘black hole stars!’
