The formation process involved two stages, said Mitchell Begelman, a professor and the chair of CU-Boulder's astrophysical and planetary sciences department. The predecessors to black hole format...
Physics and Astronomy |A protein known to stimulate blood vessel growth has now been found to be responsible for the cell overgrowth in the development of polyps that characterize one of the most severe forms of sinusitis, ...
Health and Medicine |NASA's QuikScat satellite uses microwave technology to peer through a tropical cyclone's clouds, and actually read the speed of the rotating surface winds. In an overpass from space at 7:58 ...
Earth Sciences |The only October in the past 31 that was warmer in the tropics than last month was October 1987, when the average temperature in the tropics was 0.53 C (about 0.95 degrees Fahrenheit) warmer than seas...
Earth Sciences |Purdue University and NASA examined more than a dozen chemicals, most of which are generated by humans, and have developed a blueprint for the underlying molecular machinery of global warming. The res...
Life Sciences |The oceans play a key role in regulating climate, absorbing more than a quarter of the carbon dioxide that humans put into the air. Now, the first year-by-year accounting of this mechanism during the ...
Earth Sciences |At 1500 UTC (10 a.m. ET) on November 17, Anja's maximum sustained winds were sustained at 75 knots (86 mph). Anja's center was located 715 miles east-northeast of La Reunion Island, near 18....
Earth Sciences |This discovery could pave the way for the relatively rapid development of a vaccine against Chlamydia."Now that we know how the body defends itself against the Chlamydia bacteria, we can ...
Health and Medicine |Since 1990, scientists and mission controllers at ESA and NASA have noticed that their spacecraft sometimes experience a strange variation in the amount of orbital energy they exchange with Earth duri...
Physics and Astronomy |The ELCs will provide scientists with a platform and infrastructure to deploy experiments in the vacuum of space without requiring a separate dedicated Earth-orbiting satellite, and will also serve as...
Physics and Astronomy |The SUNRISE balloon-borne telescope, a collaborative project between the Max Planck Institute for Solar System Research in Katlenburg-Lindau and partners in Germany, Spain and the USA, has now deliver...
Physics and Astronomy |In celebration of this International Year of Astronomy, NASA is releasing images of the galactic center region as seen by its Great Observatories to more than 150 planetariums, museums, nature centers...
Physics and Astronomy |People love to get the big picture of hurricane alleys, and thanks to the GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Md., they can now get real-time satellite animations of ...
Earth Sciences |On November 6, 2009 at 1147 UTC (7:47 a.m. ET) TRMM revealed Ida had weakened to a tropical depression after coming ashore in eastern Nicaragua on November 5. TRMM identified the location of Ida'...
Earth Sciences |The findings show that "stellar nurseries" within the first galaxies gave birth to stars at a much more rapid rate than previously expected, the researchers from Durham's Institute for ...
