If you were alive and interested in astronomy then, you'll remember Supernova 1987A, the 1st supernova visible in Earth's skies since 1604. The new timelapse shows its aftermath over a 25-year period, 1992 to 2017.

A study released this past week reports that oceans absorbed 60 percent more heat than previously thought. The study estimates that for each of the past 25 years, oceans have absorbed an amount of heat energy that is 150 times the energy humans produce as electricity annually.

One half of the W of Cassiopeia is more deeply notched than the other half. This deeper V is your "arrow" in the sky, pointing to the Andromeda galaxy.
