“Only a few short years ago, when the APOD editors were in graduate school, the pervasive, cosmic Dark Energy was not even seriously discussed. Of course, it now appears that this strange energy dominates the cosmos (as well as lectures on cosmology) and provides a repulsive force accelerating the large scale expansion of the Universe. In fact, recent brightness measurements of distant and therefore ancient, stellar explosions or supernovae indicate that the universal expansion began to speed up in earnest four to six billion years ago, when the Dark Energy’s repulse force began to overcome the attractive force of gravity over cosmic distances. The Hubble Space telescope images above show a sample of the distant supernova explosions, billions of light-years away, in before (top) and after (bottom) images of their faint host galaxies. Hubble measured supernovae also hint that the Dark Energy’s repulsive force is constant over cosmic time and so could be consistent with Einstein’s original theory of gravitation. If the force actually changes with time, the Universe could still end in a Big Crunch or a Big Rip … but not for an estimated 30 billion years.” —APOD

“Justices of the Massachusetts Supreme Judicial Court ruled 5-2 Monday in favor of full, equal, and mandatory gay marriages for all citizens. The order nullifies all pre-existing heterosexual marriages and lays the groundwork for the 2.4 million compulsory same-sex marriages that will take place in the state by May 15.

‘As we are all aware, it’s simply not possible for gay marriage and heterosexual marriage to co-exist,’ Massachusetts Chief Justice Margaret H. Marshall said. ‘Our ruling in November was just the first step toward creating an all-gay Massachusetts.'” —The Onion
