Jane Poynter and Taber MacCallum are planning a trip to Mars. They’ve been hashing out the details for 20 years now, and alternate between being extremely excited and utterly terrified by the prospect, refusing to discuss it after 5 p.m. to avoid nightmares.

Two exoplanets, once considered excellent candidates in the search for life elsewhere in the Universe, do not exist, according to a new study in the journal Science. Both non-planets, Gliese 581d and 581g, were thought to be part of the Gliese 581 star system, located only 20 light-years away.

What came first, the black hole at the center of a spiral galaxy (drawing material to itself), or the galaxy first then the black hole?
