Two suns were seen setting in the China sky. Videos of the sight have baffled scientists after an earlier report was ridiculed warning of a nearby star explosion that would appear to be another sun. Could there really be another sun-like star or is it just an optical illusion? Via Mother Nature Network:
Weeks after a story shot across the Web claiming that the imminent explosion of a nearby star would result in the appearance of a second sun in the sky – a story that was later debunked – two suns were caught on camera yesterday in China. The suns – one fuzzy and orange, the other a crisp yellow orb – appeared side-by-side, one slightly higher than the other.
What’s going on? Life’s Little Mysteries, a sister site to Space.com, asked Jim Kaler, the University of Illinois astronomer who squelched the excitement over the aforementioned exploding Betelgeuse and who has written books on the day and night sky. The double sun image is an effect of optical refraction, Kaler said, but it’s a “pretty darn rare” one, and one not fully explained by science.“I doubt it’s been computer modeled,” he said. “There must have been some blob of atmosphere somewhere that caused this truly spectacular phenomenon, which in a sense is a mirage.” [Amazing Sun Photos From Space]
