A New Nova Just Appeared in the Night Sky – You Can See It with the Naked Eye

10 months ago

Astronomers are anticipating the explosion of T Coronae Borealis, a recurring nova, but a new unexpected nova named V462 Lupi has appeared.
A nova is a stellar object that suddenly brightens, visible from Earth with small telescopes or the naked eye, distinct from a supernova.
V462 Lupi, detected on June 12, is a classical nova involving a white dwarf stealing material from a companion star, leading to a bright explosion.
The white dwarf accumulates material from a companion star (often a red giant), and the pressure buildup causes a detonation, resulting in the nova's brightness.
The term 'nova' comes from Latin 'stella nova' meaning 'new star,' as novae appear suddenly in the sky, challenging historical views of an immutable universe.
V462 Lupi is located in the Lupus constellation, visible in the Southern Hemisphere and up to 35 degrees latitude in the Northern Hemisphere.
Discovered at magnitude 8.7, V462 Lupi has brightened to magnitude 6.1, making it 11 times brighter and nearly visible to the naked eye in dark skies.
The nova has made the system over 3 million times brighter than its original magnitude of 22.3.
