A Comet’s Missing Light
On 28 November 2013, comet ISON passed within two solar radii of the Sun’s surface. But instead of shining in extreme ultraviolet light as predicted, ISON was never detected.

An Active Black Hole in a Compact Dwarf
There’s a new addition to the galaxy zoo: a small, compact, and old elliptical galaxy that shows signs of a monster black hole actively accreting material in its center.
Record-Breaking Eclipsing Binary
The new record holder for longest-period eclipsing binary is TYC-2505-672-1, an unusual system in which the companion star may be shrouded by a circumstellar disk.
