- Recently, the National Aeronautics and Space Administration’s (NASA) Hubble Space Telescope has confirmed that the huge Bernardinelli-Bernstein comet is indeed the largest icy comet nucleus ever seen by astronomers.
- The nucleus is called the C/2014 UN271 which has an estimated diameter of almost 129 kilometers.
- The nucleus is around 50 times larger than that of most known comets, and its mass is estimated to be around 500 trillion tonnes.
- The comet was discovered by astronomers Pedro Bernardinelli and Gary Bernstein in archival images from the Dark Energy Survey at an astronomical observatory in Chile.
- It was discovered in November 2010 and has been intensively studied since.
