Two Stars Suddenly Start Exploding Out of Nowhere?

Two stars have quietly gone supernova:

The first nova, dubbed V462 Lupi, was initially spotted June 12 shining in the Lupus constellation, after its progenitor star suddenly became more than 3 million times brighter than normal. Then, on June 25, multiple astronomers detected another nova, dubbed V572 Velorum, within the Vela constellation, according to EarthSky.org. Astronomers normally expect to see a classical nova once a year at most, and more than one of these explosions shining simultaneously is almost unheard of.
