I like interpreting astronomy in terms of relationship advice. For instance this one means:

Two people together can sometimes be much more destructive than they are alone. Especially if they are middle-aged burn-outs!

Two small but dense burned-out stars appear to have spiraled into each other and exploded, according to a new study.

The blast offers some of the strongest evidence yet for a theoretical model for supernovas created by white dwarfs—the hot cores left behind when stars similar to our sun die.

The finding could also have implications for studies of dark energy, a mysterious force thought to make up more than 70 percent of the universe.

Most white dwarf supernovas are believed to occur when the tiny dead stars siphon so much material from a larger, nearby star that they trigger a massive fusion reaction and explode.

The same explosion could also occur, however, if two white dwarfs merged, said Malcolm Hicken, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts.

Current models classify supernovas as either Type I or Type II, the major difference being that only Type II blasts show evidence of hydrogen.
