We live in a hierarchical Universe where small structures join into larger ones. Earth is a planet in our Solar System, the Solar System resides in the Milky Way Galaxy, and galaxies combine into groups and clusters. Clusters are the largest structures in the Universe, but sadly our knowledge of them is not proportional to their size. Researchers have long known that the gas in the centers of some galaxy clusters is rapidly cooling and condensing, but were puzzled why this condensed gas did not form into stars. Until recently, no model existed that successfully explained how this was possible. http://www.physorg.com/news166793207.html Space & Earth Tue, 14 Jul 2009 12:27:35 EST news166793207 US ambitions of returning to the moon by 2020 and then heading to Mars risk being grounded because of "unrealistic" funds allocated to NASA, said Senator Bill Nelson, a former space shuttle astronaut. http://www.physorg.com/news164510544.html Space & Earth Thu, 18 Jun 2009 05:00:01 EST news164510544 (PhysOrg.com) -- First motion is almost always a big event in the world of space exploration. Whether the first motion is of a wheel beginning to rotate or a rocket lifting off the pad, first motion means things are definitely changing. On day four of the upcoming shuttle servicing mission of the Hubble Space Telescope, there will be another such significant first motion. It will begin when a bolt that has been frozen in place for a decade and a half completes its 20th counterclockwise rotation. http://www.physorg.com/news161276505.html Space & Earth Mon, 11 May 2009 16:02:16 EST news161276505 An imaging coronal spectrograph called SPICE (Spectral Imaging of the Coronal Environment), designed by scientists and engineers at Southwest Research Institute in Boulder has been selected by ESA and NASA for the European Space Agency's Solar Orbiter mission to explore the innermost regions of the solar system from the closest distances to the Sun ever attempted. Solar Orbiter will be positioned at a unique vantage point, about one-fourth the distance of the Earth from the Sun. http://www.physorg.com/news156956348.html Space & Earth Sun, 22 Mar 2009 15:59:54 EST news156956348 (PhysOrg.com) -- The first robot that can jump like a grasshopper and roll like a ball could play a key role in future space exploration. http://www.physorg.com/news147617121.html Electronics Thu, 04 Dec 2008 12:45:21 EST news147617121
