In what sounds like a cosmic episode of “CSI,” sleuthing astronomers have figured out what touched off a stellar explosion 545 million light-years away, based on evidence left behind at… Read More
Big data just might give astronomers a better grip on the answer to one of the biggest questions in physics: Exactly what’s behind the mysterious acceleration in the expansion rate… Read More
Calling all citizen scientists: The Australian National University wants you to join the search for supernovae. Brad Tucker from the ANU Research School of Astronomy and Astrophysics says it’s not… Read More
Researchers say they’ve found evidence of supernova explosions that spewed radioactive fallout over Earth during the age when humanity’s ancestors were evolving into upright-walking, big-brained creatures. One of two studies published in the… Read More
Astronomers traced one of the weirder twists in relativity to determine when they’d see an “instant replay” of a distant supernova, and now the Hubble Space Telescope has shown that their prediction was… Read More
