Seeking to detect mysterious, ultra-high-energy neutrinos from distant regions of space, a team of astronomers used the Moon as part of an innovative telescope system for the search. Their work gave new insight on the possible origin of the elusive …
Amsterdam, November 17th, 2010¬ — Black holes, or the remnants of hyper-or supernova explosions, have intrigued scientists since the concept was first introduced in 1967. Astronomers have only ever been able to observe gamma-ray bursts, considered…
