The nova (literally “new star”) Sagittarius 2015 No. 2 has brightened to magnitude 4.3 — enough for naked-eye visibility, which is not unheard of, but not very common either. If your skies are favorable tonight (mine aren’t — we’re in a winter storm advisory here, with thick clouds overhead) and if you can see Sagittarius from your location, go outside and take a peak at this new star!
Astronomers watching the event say that that its consistent with a white dwarf star undergoing a hydrogen fusion explosion on its surface. It may start dimming soon, so if you have the chance, go out and take a peak! Watch the spot over the next few weeks as it dims and eventually disappears from view.
