Just days after a #nova appeared in the night sky, another joined it. V572 Velorum, in the constellation Vela, joins V462 Lupi in Lupus. Both are now visible to the naked eye to observers in the Southern Hemisphere and are currently shining millions of times brighter than usual. The remarkable coincidence — judged to be extremely rare by astronomers — has occurred as astronomers await the explosion of T Coronae Borealis (T CrB) in Corona Borealis, which is known to explode and shine brightly every 80 years or so.
