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 Twenty-four unusual stars, 18 of them newly discovered, have been observed in new Hubble telescope images. The stars are white dwarfs, a common type of dead star, but they are odd because they are made of helium rather than the usual carbon and oxygen. This is the first extensive sequence of helium-core white dwarfs to be observed in a globular cluster, a dense swarm of some of the oldest stars in our galaxy. http://www.physorg.com/news159700039.html Space & Earth Thu, 23 Apr 2009 10:07:52 EST news159700039 (PhysOrg.com) -- When cities turn off their lights for Earth Hour their occupants will get more than a warm and fuzzy green feeling, they will also see stars hundreds of trillions kilometres away lighting up a moonless night sky in all its glory. http://www.physorg.com/news156627581.html Space & Earth Wed, 18 Mar 2009 20:41:41 EST news156627581 A new project, the Apache Point Observatory Galactic Evolution Experiment, or APOGEE, will survey more than 100,000 Milky Way red giant stars -- bright, bloated stars in a late stage of their evolution. APOGEE will provide enormous new insight to the processes that make stars and that drive the formation and evolution of galaxies. http://www.physorg.com/news148573532.html Space & Earth Mon, 15 Dec 2008 14:25:32 EST news148573532 (PhysOrg.com) -- Astronomers have long puzzled over why a small, nearby, isolated galaxy is pumping out new stars faster than any galaxy in our local neighborhood. http://www.physorg.com/news146410412.html Space & Earth Thu, 20 Nov 2008 13:33:32 EST news146410412
