|China had two suns recently and there seems to be no valid explanation for the odd phenomenon. The appearance of the two suns comes just weeks after a rumor sent the web into a frenzy by saying that a star would soon blow up causing two suns to appear in the sky. Was this the star showing up or is there some other explanation for the odd event?
If nearby star Betelgeuse goes supernova we could end up with two suns in the sky.
Dr. Brad Carter of the University of Southern Queensland detailed a scenario in which if Betelgeuse went supernova it would create what would appear to be a second sun in the sky for several weeks, despite it being 1300 light years away.
Earth could be getting a second sun, at least temporarily. Dr. Brad Carter, Senior Lecturer of Physics at the University of Southern Queensland, outlined the scenario to news. com. au. Betelgeuse, one of the night sky‘s brightest stars, is losing mass, indicating it is collapsing. It could run out of fuel and go super-nova at any time.
The Four Suns of HD 98800
How would it look to have four suns in the sky? Planets of the HD 98800 system, if they exist, would experience such a view.
HD 98800 is a multiple star system about 150 light years from Earth — right in our section of the Milky Way Galaxy. For years it has been known that HD 98800 consists of two pairs of double stars, with one pair surrounded by a disk of dust. Recent data from the Earth-trailing Spitzer Space Telescope in infrared light indicate that the dust disk has gaps that appear consistent with being cleared by planets orbiting in the disk. If so, one planet appears to be orbiting at a distance similar to Mars of our own Solar System. Pictured above is an artist’s drawing of how the HD 98800 system might appear to a nearby observer.
