The Moon, just one day past full, will occult Leo’s brightest star, Regulus, tonight (2/2). From West Michigan, Leo’s blazing heart suddenly disappears at about 8:45pm EST, only to dramatically reappear at 9:43pm. Make sure to observe the occultation with binoculars or a telescope for a better view.

It's really cold out there today, but hopefully this fact will help. One of the coldest places in the solar system is on Neptune's largest moon (by far), Triton. Its average surface temperature is -235° C (-391° F). Feel better? 🥶
