Plenty of dark matter near the Sun

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.

Transformed X-48c flies successfully

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.

Astronomers crack mystery of the 'monster' stars

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? NASA's Mars rover aims to find out

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.

NASA investigates proton radiation effects on cells

A team of researchers at NASA's Johnson Space Center in Houston and Lawrence Berkeley National Laboratory in Berkeley, Calif., has found radiation from protons could further enhance a process that occurs during tumor progression. 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.

Thin current sheets in space: where the action is

Around Earth, the processes accelerating electrons which hit the atmosphere and cause beautiful auroras are often initiated in thin current sheets. Similar processes, auroras and thin current sheets are found around other planets such as Jupiter and Saturn.

Taking the heat: Aeroshell to protect NASA's Mars Science Laboratory on descent through Martian atmosphere

After a journey of 245 days across 352 million miles, the moment of truth for the Mars Science Laboratory begins late in the evening of August 5 when the spacecraft roars into the Martian atmosphere, traveling at 13,200 miles an hour. The final seven minutes will determine the fate of the mission, and a perfect performance of the Lockheed Martin Space Systems aeroshell is absolutely vital to getting the Mars Curiosity Rover safely down on the sands of Mars.
