Stars in early galaxies zoom, zoom, zoom
“We do find stars with comparable speeds in mature galaxies in today’s nearby universe, but those galaxies are typically many tens of thousands of light years across,” says lead researcher Pieter van Dokkum. “Here we have a very small galaxy in the young universe whose stars behave as if they were in a giant galaxy.” (Credit: NASA, ESA, and A.

Don’t blame comets for Earth’s extinctions
This Hubble picture, taken on July 23, by the new Wide Field Camera 3, is the sharpest visible-light picture taken of the atmospheric debris from a comet or asteroid that collided with Jupiter on July 19. This is Hubble’s first science observation following its repair and upgrade in May. The size of the impactor is estimated to be as large as several football fields. (Credit: NASA, ESA, and H.
