Astronomy Pix of the Fortnight XLVII

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.

This interactive flash animation is a modern version of the classic video Powers of Ten.  By moving the scroll bar across the bottom you can explore a diversity of sizes – from the infinitesimal to the infinite.  Click on different items to bring up descriptive information.

Per usual, see below the jump for descriptions…
