(PhysOrg.com) -- A collection of 30 never-before-released images of embryonic planetary systems in the Orion Nebula are the highlight of the longest single Hubble Space Telescope project ever dedicated to the topic of star and planet formation. Also known as proplyds, or protoplanetary discs, these modest blobs surrounding baby stars are shedding light on the mechanism behind planet formation. Only the NASA/ESA Hubble Space Telescope, with its high resolution and sensitivity, can take such detailed pictures of circumstellar discs at optical wavelengths. http://www.physorg.com/news180018260.html Space & Earth Mon, 14 Dec 2009 13:05:25 EST news180018260 Understanding the evolution of galaxies is one of the biggest questions confronting astronomers today. Looking at distant astronomical objects gives scientists important clues to the origins of the Milky Way Galaxy and other galaxies in the local universe. http://www.physorg.com/news179512073.html Space & Earth Tue, 08 Dec 2009 16:28:26 EST news179512073 (PhysOrg.com) -- In the early part of the 20th Century, Carnegie astronomer Edwin Hubble discovered that the universe is expanding. The rate of expansion is known as the Hubble constant. Its precise value has been hotly debated for all of the 80 intervening years. The value of the Hubble constant is a key ingredient in determining the age and size of the universe. http://www.physorg.com/news150383835.html Physics Mon, 05 Jan 2009 13:17:15 EST news150383835
