CBNNews.com - REHOVOT, Israel - Researchers at Israel's Weizmann Institute of Science and their U.S. counterparts at San Diego University watched the largest ever star observed to date explode.
Israeli and American scientists guessed the supernova (exploding star) was between 50 to 100 times as large as the earth's sun.
Dr. Avishai Gal-Yam of the Weizzman Institute and Prof. Douglas Leonard of San Diego University, who identified the supernova, said that most of its mass imploded inward to its collapsing core, leaving a black hole -- an area too dense for light to escape, making it virtually invisible.
Generally, a supernova's explosion can be seen hundreds of light years away, even in daylight, but this one was so big that even its light waves could not escape, making it invisible, for all intents and purposes.
