Astronomers Observe Fast Growing Primitive Black HolesWednesday, March 17, 2010 @ 7:20PMby Staff Writers Copenhagen, Denmark (SPX) Mar 18, 2010 Quasars are active and very powerful black holes at the centre of distant galaxies.

Planck Sees Tapestry Of Cold DustWednesday, March 17, 2010 @ 7:20PMby Staff Writers Paris, France (ESA) Mar 18, 2010 Giant filaments of cold dust stretching through our Galaxy are revealed in a new image from ESA's Planck satellite. Analysing these structures could help to determine the forces that shape our Galaxy and trigger star formation.

Planck images the galaxy's cold dustWednesday, March 17, 2010 @ 3:48PMPASADENA, Calif., March 17 (UPI) -- The Planck spacecraft -- part of a European Space Agency-led mission -- has nearly completed the first of at least four separate scans of the entire sky.

Fast growing primitive black holes discoveredWednesday, March 17, 2010 @ 3:14PMThe most distant quasars found in the early universe, a mere 800 million years after the Big Bang, have been observed by astronomers.

Fast Growing Primitive Black Holes ObservedWednesday, March 17, 2010 @ 1:57PMEnormous black holes"Quasars are a very early stage of galaxies, a sort of baby galaxies", explains Marianne Vestergaard, astrophysicist at the Dark Cosmology Center at the Niels Bohr Institute at the University of Copenhagen. "Most galaxies have a massive black hole with a mass of over a million solar masses, but quasars are different. Their black holes are active and growing. The gravity of ...

Planck Images Tapestry Of Cold DustWednesday, March 17, 2010 @ 10:57AMImage 1: The image spans about 50 degrees of the sky. It is a three-color combination constructed from Planck’s two highest frequency channels (557 and 857 GHz, corresponding to wavelengths of 540 and 350 micrometers), and an image at the shorter wavelength of 100 micrometers made by the IRAS satellite. This combination visualizes dust temperature very effectively: red corresponds to ...

Cosmic tapestry: Giant filaments of cold dust stretch through Milky WayWednesday, March 17, 2010 @ 10:30AMGiant filaments of cold dust stretching through the Milky Way are revealed in a new image from the European Space Agency's Planck satellite. Analyzing these structures could help to determine the forces that shape our galaxy and trigger star formation.

Planck Reveals Giant Dust Structures in our Local NeighborhoodWednesday, March 17, 2010 @ 9:18AMDust has never looked so beautiful! This new image from the Planck spacecraft shows giant filaments of cold dust stretching through our galaxy. The image spans about 50 degrees of the sky, showing our local neighborhood within approximately 500 light-years of the Sun. “What makes these structures have these particular shapes [...]
