In this issue: Earth’s “second moon,” an angry hot pink Sun, a hamburger and other unusual nebulae, updated trans-Neptune objects, and a black-hole-less galactic core.
Also: mark you calendars for a “Super Moon” on May 5 (~8:30) It’s the combination of a Full Moon, at perigee, on the horizon. It’ll be brighter, 12% larger and super-sized by the optical illusion created at the horizon when other objects (building, trees) are in frame. This video is a 2 minute history of the moon, pretty cool.
