History

Historical Context

Astronomers recently observed Type Ia supernova SN 2022abvt, located 400 million light-years away, using the Hubble Space Telescope. This discovery builds on the 1998 finding that such supernovae can serve as standard candles for measuring cosmic distances, a breakthrough that led to the 2011 Nobel Prize in Physics. These observations continue to support the Lambda-CDM model of an accelerating universe.
