noun

nova

NOH-vuh/ˈnəʊvə/

A star that suddenly becomes much brighter and then fades.

The second telescope view shows the nova shining much brighter.

Two matched telescope views show the same star field moments apart: a small, faint star in the first becomes intensely bright in the second, while surrounding stars remain unchanged.
Etymology

Latin novus supplied the description “new” in “new star.” A star’s sudden brightening made it appear newly present or previously unknown, giving this astronomical event its name.
