With the help of an automated supernova-hunting pipeline and a galaxy sitting 2 bil-lion light years away from Earth that's acting as a "magnifying glass,'' astronomers have captured multiple images of a Type Ia supernova—the ...

(PhysOrg.com) -- Several ways have been proposed to examine dark energy, in hopes of finding out just what it is. One of them, "supernovae" for short, certainly works: it's how dark energy was discovered in the first place. ...
