The first images from Curiosity's color Mast Camera, or Mastcam, have been received by scientists at NASA's Jet Propulsion Laboratory in Pasadena, Calif. The 130 low-resolution thumbnails, which were received Thursday morning, provide scientists and engineers of NASA's newest Mars rover their first color, horizon-to-horizon glimpse of Gale Crater.

An international team of researchers used a state-of-the-art simulation of the Milky Way to test their mass-measuring method before applying it to real data. This threw up a number of surprises: they noticed that standard techniques used over the past twenty years were biased, always tending to underestimate the amount of dark matter.

The aircraft, designed by The Boeing Co. and built by Cranfield Aerospace Limited of the United Kingdom, is flying again in partnership with NASA. The new X-48C model, which was formerly the X-48B Blended Wing Body aircraft, was modified to evaluate the low-speed stability and control of a low-noise version of a notional, future Hybrid Wing Body aircraft design.

In 2010 scientists discovered four 'monster' sized stars, with the heaviest more than 300 times as massive as our Sun. Scientists have now found an explanation: the ultramassive stars were created from the merger of lighter stars in tight binary systems.

Are we alone? Or was there life on another planet? NASA's $2.5 billion dream machine, the Mars Science Laboratory, aims to take the first steps toward finding out when it nears Mars' surface on Monday. NASA said it will find out if its Mars Science Laboratory and rover, Curiosity - designed to hunt for soil-based signatures of life and send back data to prepare for a future human mission - landed safely at 1:31 am Eastern time on Monday.

This information may help lead to better methods to protect astronauts from the harmful effects of radiation in space, as well as help cancer researchers on Earth better understand the effects of radiation treatment on the human body.
