Nova explosion will be visible to naked eye in rare stargazing event

A rare cosmic eruption is expected to occur in the Milky Way in the coming months — an outburst so bright that a “new” star will seemingly appear for a short time in the night sky. The event, known as a nova, will be a once-in-a-lifetime skywatching opportunity for those in the Northern Hemisphere, according to NASA, because the types of star systems in which such explosions occur are not common in our galaxy.

Astronomers around the world are monitoring activity in the T Coronae Borealis system. Once an eruption is detected, Schaefer said, the best and brightest views will likely come within 24 hours, when it reaches roughly the same brightness as the North Star. The outburst may remain visible to the naked eye for a couple of days before it begins to fade. Even after it dims, skywatchers will likely still be able to spot the eruption for around a week using binoculars, according to NASA.
