U.S. scientists say they've discovered a radio supernova -- an exploding star seen only at radio wavelengths and undetectable by optical or X-ray telescopes. This supernova is the nearest supernova in five years, yet it is completely obscured in optical, ultraviolet and X-rays due to the dense medium of the galaxy, said University of California-Berkeley Assistant Professor Geoffrey Bower. This just popped out. In the future, we want to go from discovery of radio supernovas by accident to...

New radio surveys could turn up many supernovas hidden within gas and dust The chance discovery last month of a rare radio supernova - an exploding star seen only at radio wavelengths and undetected by optical or X-ray telescopes - underscores the promise of new, more sensitive radio surveys to find supernovas hidden by gas and dust. "This supernova is the nearest supernova in five years, yet is completely obscured in optical, ultraviolet and X-rays due to the dense medium of the galaxy,"...
