《FatherShit Ent》A newly discovered comet — C/2025 R2 (SWAN25B) — is heading toward Earth’s inner solar system and is expected to become visible to the naked eye in late October, sparking global excitement among skywatchers and astronomy fans.
What Is SWAN25B?
First detected by the Solar Wind ANisotropies (SWAN) team in September 2025, this long-period comet originates from the distant Oort Cloud. As it approaches the Sun, it’s becoming brighter and developing a visible greenish coma and tail.
Astronomers predict that from October 20 to 27, SWAN25B could reach brightness levels sufficient for naked-eye visibility, especially in dark-sky locations.
Best Time and Tips to Watch the Comet:
Best Viewing Period: October 20–27, between 10 PM and 2 AM
Direction: East to northeast, depending on your location
Tools: Binoculars, DSLR camera, or telescope (optional)
Conditions: Dark skies, minimal light pollution, clear weather
Apps like SkySafari, Star Walk 2, or Stellarium can help locate the comet in real-time.
Why Does It Glow Green?
The eerie green glow comes from gases in the comet’s coma — mainly cyanogen (CN) and diatomic carbon (C₂) — which emit green light when excited by solar ultraviolet radiation.
