This image shows a cross-sectional view of one-half of a solar-mass target cloud being struck by a supernova shock front that is traveling downward. The colors represent the target cloud, with redder colors representing denser regions. The solid black contours delineate material that ...
The astronomers used the world’s largest fully steerable radio telescope, which stands 485 feet tall -- taller than the Statue of Liberty. (Credit: NRAO/AUI) Astronomers believe the magnetic fields within our own Milky Way and other nearby galaxies—which control the rate of star formation ...
"H-alpha emissions only occur in the vicinity of very heavy stars," explains Jan Pflamm-Altenburg of the Argelander Institute of Astronomy at Bonn University. It has long been accepted that heavy and light stars are always born in a certain ratio to each other. One "H-alpha baby" is thought to be ...
NASA’s MESSENGER spacecraft carrying an $8.7 million University of Colorado at Boulder instrument will make its second flyby of Mercury Oct. 6. The desk-sized spacecraft will settle into Mercury orbit in 2011 after having made 15 loops around the sun since its 2004 ...

3D view of a few scallops. The ridges are asymmetrical with a steeper, shorter, scarp-facing-slope and form steps on the scallop floor (HiRISE image PSP_001938_2265 overlaid on a HiRISE DEM). (Credit: NASA/JPL/University of Arizona) Professor Alfred McEwen, HiRISE’s Principal Investigator, highlighted some of the ...
A student in the Student Space Systems Fabrication Laboratory works on a CubeSat. The Radio Aurora Explorer satellite will be made of three CubeSats.
