Is it true that on an average day on Earth, thousands of supernovas happen some place in the universe?
Nice thought isn't it? I would guess that's right, but I don't have figures.Is it true that on an average day on Earth, thousands of supernovas happen some place in the universe?
http://www.lbl.gov/Science-Articles/Archive/supernova-search.htmlIn an experiment involving an automated telescope and a sensitive electronic detection system, members of LBL's Automated Supernova Search team have found 20 supernovas, most of them in the last three years. Analysis of the data suggests that supernovas occur at least once every 30 years in galaxies like our own, and maybe even more often. In the past, supernovas were thought to occur in Milky Way-type galaxies no more than once in 100 to 300 years.
