An astronomer in Italy caught a fortuitous image of the bright comet Lemmon seemingly entwined with the glowing trail of a "shooting star."

Comet Lemmon is moving quickly west of the Big Dipper, near bright Arcturus, while Comet SWAN lies beneath the three stars that form the Summer Triangle. About 90 minutes after sunset is when to look for both.

Comet C/2025 A6 (Lemmon) will pass through the neck of the great celestial serpent represented by the constellation Serpens Caput on the nights of Oct. 26-27.

The interstellar object 3I/ATLAS has gathered significant scientific attention, and soon it will reach its closest point to the sun.

Lemmon, which is a rare green comet, can be seen with the naked eye on Oct. 21, according to the Royal Astronomical Society, with peak visibility near Halloween. SWAN may be visible using binoculars or a telescope, according to Starwalk, a real-time astronomical app for stargazing.

Brooks, which visits the Earth roughly every 71 years, was spotted releasing intriguing radio signals last year.

But if you're out and about this final week of October, you can still spot these green gaseous globes and their streaming tails.You'll be able to see Lemmon without any equipment, but SWAN will be pretty faint,

Harvard Professor Avi Loeb discusses the mystery surrounding the 31/ATLAS comet and explains his argument that it has a 40% chance of being alien technology.
