Gravity remains the dominant force on large astronomical scales, but when it comes to stars in young star clusters the dynamics in these crowded environments cannot be simply explained by the pull of gravity.
Scientists believe that their light source is a very bright gaseous disk surrounding a supermassive black hole at the center of the galaxy. Gas streams called "outflows" move outward from the disk and have a substantial influence on surrounding interstellar/intergalactic regions. However, because quasars at large distances look like mere stars, their internal structures are not easy to investigate.
The fledgling Beidou satellite navigation system will soon benefit hundreds of millions of users, and provide a cheaper and in some cases better alternative than the Global Positioning System, industry specialists said.
Australian researchers have developed a substance that looks and behaves like soil from the moon's surface and can be mixed with polymers to create 'lunar concrete', a finding that may help advance plans to construct safe landing pads and mines on the moon.
SpaceWorks Enterprises, Inc. (SEI) today released an update to its nanosatellite and microsatellite market analysis study. The study presents the latest observations, trends, and projections for the nano/microsatellite market.
University faculty and students interested in learning how to build scientific experiments for spaceflight are invited to join RockOn 2013 from June 15-20 at NASA's Wallops Flight Facility in Virginia.
NASA, universities and private groups in the US are working on asteroid warning systems that can detect objects from space like the one that struck Russia last week with a blinding flash and mighty boom.
Performing sensitive biological experiments is always a delicate affair. Few researchers, however, contend with the challenges faced by Cheryl Nickerson, whose working laboratory aboard the International Space Station (ISS) is located hundreds of miles above the Earth, traveling at some 17,000 miles per hour.
