Although at first these emissions seem too faint to detect, recent observations have shown that they may be stronger than previously thought. In a new study, scientists have developed a model that predicts that gamma rays from hundreds of dark matter clumps should be detectable by the Fermi satellite that was launched in June 2008. http://www.physorg.com/news169121408.html Physics Mon, 10 Aug 2009 11:10:36 EST news169121408 (PhysOrg.com) -- A study published this week in the journal Nature offers an explanation for the origin of dwarf spheroidal galaxies.

The riddle has obsessed astronomers and physicists since the 1930s, when Caltech professor Fritz Zwicky first predicted its existence. Because dark matter neither emits nor reflects light and cannot be directly observed, no one has ever proven that it exists; yet theories show it makes up as much as a quarter of the universe. Columbia physics professor Elena Aprile, with collaborators from universities around the world, including Rice University and UCLA, is leading the race to find and identify dark matter for the first time. http://www.physorg.com/news167927738.html Physics Mon, 27 Jul 2009 15:36:47 EST news167927738 Ten years ago, on July 23, 1999, NASA's Chandra X-ray Observatory was launched aboard the space shuttle Columbia and deployed into orbit.

That is the percentage of the known Universe that is missing. As in it is not there. Or at least if it is there, we can't see it. We call this unseen stuff "dark matter". That has been well known for sometime. What is trickier in answering is why? Why is it that 95% of the universe is made up of this so-named "dark matter?" An even trickier question is where? As in where is this dark matter? It is those two questions that have plagued physicists for decades. Dark matter, by its own definition cannot be seen, hence its name. So how do we "see" it, how do we know "where" to look? http://www.physorg.com/news167555163.html Physics Thu, 23 Jul 2009 09:00:02 EST news167555163 (PhysOrg.com) -- A team of researchers working with data from ESA`s Integral gamma-ray observatory has disproved theories that some form of dark matter explains mysterious radiation in the Milky Way. http://www.physorg.com/news167493073.html Space & Earth Wed, 22 Jul 2009 15:40:01 EST news167493073 (PhysOrg.com) -- The earliest stars in the universe formed not only as individuals, but sometimes also as twins, according to a paper published today in Science Express.
