Astronomers have tracked down a gigantic, previously unknown assembly of galaxies located almost seven billion light-years away from us. The discovery, made possible by combining two of the most powerful ground-based telescopes in the world, is the first observation of such a prominent galaxy structure in the distant Universe, providing further insight into the cosmic [...]

An unusual supernova rediscovered in seven-year-old data may be the first example of a new type of exploding star, possibly from a binary star system where helium flows from one white dwarf onto another and detonates in a thermonuclear explosion.
In a paper first published online Nov. 5 in the journal Science Express, University of California, [...]

Breaking up may actually not be hard to do, say scientists who`ve found a population of tropical butterflies that may be on its way to a split into two distinct species.
The cause of this particular break-up? A shift in wing color and mate preference.
In a paper published this week in the journal Science, the researchers [...]
