For decades, scientists have been searching for ghostly
neutrino particles from outer space, and now they have finally found

On April 27, a powerful flash of radiation erupted from deep
space -- the gamma-ray burst was the brightest on record, challenging
some of the leading theories on how the most powerful explosions in the
known Universe occur.
Scientists have found a huge, diffuse ring of dust near the
orbit of Venus, marking the second time such a structure has been
discovered in our solar system.
Using data from NASA's Wide-field Infrared Survey Explorer
(WISE), astronomers have detected two ancient "failed stars" that are
likely 10 billion years old
