http://www.cfa.harvard.edu//press/ CfA Press Releases en-us http://www.cfa.harvard.edu/press/2008/pr200813.html June 03, 2008: We live in the Milky Way galaxy - a disk-shaped collection of about 400 billion stars including the Sun. Many of those stars and much of the dense gas between the stars concentrate into large arms that spiral outward from the galactic center. http://www.cfa.harvard.edu/press/2008/pr200812.html June 03, 2008: On Earth, making a map is as easy as taking aerial photographs or surveying a patch of land on foot. In contrast, mapping the Milky Way galaxy is a tremendous challenge. http://www.cfa.harvard.edu/press/2008/pr200811.html May 30, 2008: While walking home on November 11, 1572, astronomer Tycho Brahe idly glanced at the sky. He was surprised to see a bright star in the constellation Cassiopeia that hadn't been there before. http://www.cfa.harvard.edu/press/2008/pr200810.html May 27, 2008: On April 9, the Sun erupted and blasted a bubble of hot, ionized gas into the solar system. http://www.cfa.harvard.edu/press/2008/pr200809.html May 16, 2008: What do military detections of jet aircraft, space-based Earth observations, and studies of distant, extrasolar planets have in common? http://www.cfa.harvard.edu/press/2008/pr200808.html April 07, 2008: The leading method of finding planets orbiting distant stars spots mostly Jupiter-sized worlds. Technology limitations make it difficult to detect smaller planets. http://www.cfa.harvard.edu/press/2008/pr200807.html March 11, 2008: A team of scientists and engineers has been selected by NASA to study design concepts for a radio telescope destined for the far side of the Moon. http://www.cfa.harvard.edu/press/2008/pr200806.html March 11, 2008: Four proposals for next-generation astronomy missions, which were developed by researchers at the Harvard-Smithsonian Center for Astrophysics (CfA), have received NASA funding for yearlong studies. http://www.cfa.harvard.edu/press/2008/pr200805.html February 18, 2008: Astronomers have discovered that rocky, terrestrial planets might orbit many, if not most, of the nearby sun-like stars in the disk of our galaxy. http://www.cfa.harvard.edu/press/2008/pr200804.html February 11, 2008: Newborn stars peek out from beneath their natal blanket of dust in this dynamic image of the Rho Ophiuchi star-forming region from NASA's Spitzer Space Telescope. http://www.cfa.harvard.edu/press/2008/pr200803.html January 11, 2008: Having the sharpest pictures always is a big advantage, and a sophisticated radio-astronomy technique using continent-wide and even intercontinental arrays of telescopes is yielding extremely valuable scientific results in a wide range of specialties. http://www.cfa.harvard.edu/press/2008/pr200802.html January 09, 2008: Our planet is changing before our eyes, and as a result, many species are living on the edge. Yet Earth has been on the edge of habitability from the beginning. http://www.cfa.harvard.edu/press/2008/pr200801.html January 09, 2008: Astronomers announced today that a mystery object orbiting a star 170 light-years from Earth might have formed from the collision and merger of two protoplanets. http://www.cfa.harvard.edu/press/2007/pr200734.html December 26, 2007: Astronomers have found the best evidence yet of matter spiraling outward from a young, still-forming star in fountain-like jets. http://www.cfa.harvard.edu/press/2007/pr200733.html December 18, 2007: A furious rate of star formation discovered in a distant galaxy shows that galaxies in the early universe developed either much faster or in a different way from what astronomers have thought.
