The diversity of colours, shapes, and sizes of planetary nebulae make them fascinating objects. In this photo release Calar Alto presents a rather unique view combining both optical and near-infrared data of the Ring Nebula (M57). http://www.physorg.com/news176374973.html Space & Earth Mon, 02 Nov 2009 09:20:01 EST news176374973 (PhysOrg.com) -- A team of scientists in Australia and the United States, led by Associate Professor Miroslav Filipović from the University of Western Sydney, have discovered a new class of object which they call `Super Planetary Nebulae.` They report their work in the journal Monthly Notices of the Royal Astronomical Society. http://www.physorg.com/news169477900.html Space & Earth Fri, 14 Aug 2009 14:13:22 EST news169477900 (PhysOrg.com) -- NASA's Spitzer Space Telescope has taken its first shots of the cosmos since warming up and starting its second career. The infrared telescope ran out of coolant on May 15, 2009, more than five-and-half-years after launch, and has since warmed to a still-frosty 30 Kelvin (about minus 406 Fahrenheit). http://www.physorg.com/news168698098.html Space & Earth Wed, 05 Aug 2009 14:20:01 EST news168698098 The new observations reveal that Messier 87's halo of stars has been cut short, with a diameter of about a million light-years, significantly smaller than expected, despite being about three times the extent of the halo surrounding our Milky Way [1]. Beyond this zone only few intergalactic stars are seen. http://www.physorg.com/news162041045.html Space & Earth Wed, 20 May 2009 12:24:44 EST news162041045 (PhysOrg.com) -- The Hubble community bids farewell to the soon-to-be decommissioned Wide Field and Planetary Camera 2 onboard NASA's Hubble Space Telescope. In tribute to Hubble's longest-running optical camera, which was developed and built by NASA's Jet Propulsion Laboratory, Pasadena, Calif., a planetary nebula has been imaged as the camera's final "pretty picture." http://www.physorg.com/news161276661.html Space & Earth Mon, 11 May 2009 16:04:51 EST news161276661 The explosion of a binary star inside a planetary nebula has been captured by a team led by UCL (University College London) researchers - an event that has not been witnessed for more than 100 years. The study, published in Astrophysical Journal Letters, predicts that the combined mass of the two stars in the system may be high enough for the stars to eventually spiral into each other, triggering a much bigger supernova explosion. http://www.physorg.com/news146314696.html Space & Earth Wed, 19 Nov 2008 10:58:16 EST news146314696
