The comet can be seen in the western sky about 30 to 45 minutes after sunset through about Oct. 31. The comet C/2023 A3 Tsuchinshan–ATLAS is seen near the western horizon over the Millers ...
Glenn Sparks, a driver headed east on Interstate 40 in Tennessee, documented the moment on Facebook, writing that he had just witnessed the "most amazing meteor of my life" at around 1 a.m. on Friday.
Comet Tsuchinshan-ATLAS is expected to come within approximately 44 million miles of Earth on Saturday. Comet visible with naked eye in sky this weekend comes around only every 80,000 years Skip ...
C/2015 V2 (Johnson) is a hyperbolic comet discovered on 3 November 2015 by Jess Johnson (Catalina Sky Survey) at an apparent magnitude of 17.1 using a 0.68-meter (27 in) Schmidt–Cassegrain telescope.
The nucleus of the comet was found to rotate every 8.5 [8] to 8.7 hours. [9] In the spectrum of the comet in the wavelength range between 5000 and 7000 Å many emission lines of NH 2, C 2, and [OI] are detected. [36] [37] The spectrum of the comet was obtained on 10 March 2023 and lines associated with CN, diatomic and triatomic carbon and ...
A bright comet has made a rare appearance in the sky, and skywatchers will have several opportunities to see it before it retreats into the icy depths of space. Comet C/2023 A3, also known as ...
