Robert F. Cahalan was recently elected a Fellow of the American Meteorological Society.
Two 'starburst' galaxies, plus a satellite of our own Milky Way galaxy, represent a new category of gamma-ray-emitting objects detected both by Fermi and ground-based observatories.
Certain gases that cause warming are so closely linked with aerosol production that the emissions of one type of pollutant can affect the quantity of the other.
Using the most distant objects in the Universe to find your way home
In one year of operation, NASA's Fermi Telescope has seen more than 1,000 sources of gamma-rays, but it still can't unseat Einstein's theory of relativity.
10.26.09 - Three of the satellite instruments that will fly on an upcoming satellite mission called "FASTSAT" have been created at one NASA center and have arrived at another for more tests to ensure they are flight ready for launch.
10.26.09 - NASA's Goddard Space Flight Center in Greenbelt, Md., has selected ABSL Space Products in Longmont, Colo. to provide the GPM Lithium-Ion Battery.
10.23.09 - Once approximately every 15 years, light from the sun hits the ring particles at very low angles, giving us a three-dimensional view of the rings.
10.22.09 - To help foster diversity and collaboration in the space sciences, NASA is sponsoring the "Women in Astronomy and Space Science 2009: Meeting the Challenges of an Increasingly Diverse Workforce" conference.
10.22.09 - Every year, scientists learn something new about the inner workings of lightning.
10.20.09 - NASA technology will now be available to the medical community to help in the diagnosis and prediction of syndromes that affect the brain, such as stroke, dementia, and traumatic brain injury.
10.14.09 - After a rocky start and then a stellar 26-year performance, NASA's TDRS-1 is scheduled for decommissioning on Oct. 28, 2009.
10.09.09 - NASA is releasing six short videos and NASA scientists are participating in a live, educational webcast to coincide with Earth Science Week 2009.
10.08.09 - On October 9, LCROSS, a two-ton rocket body, will slam into a crater near the moon's south pole. Goddard's scientific visualization team helped determine how the resulting debris plume will look from Earth.
10.07.09 - For more than 19 years, NASA’s Hubble Space Telescope—one of the celebrated scientific instruments of our time—has revolutionized our understanding of the universe and how it works.
