Tornadoes are expected to accompany severe storms in the springtime in the U.S., but this time of year they also usually happen. When a line of severe thunderstorms associated with a cold front swept through the U.S. southeast on Nov. 16, TRMM collected rainfall data on the dangerous storms from space.

Its late in the Atlantic and eastern Pacific hurricane seasons, but the calendar isn't stopping the tropics. The GOES-13 satellite is keeping forecasters informed about developing lows like System 90E in the eastern Pacific and another low pressure area in the Atlantic.
System 90E and the Atlantic low pressure area were both captured in one image from the NOAA's GOES-13 satellite today, November 18, 2011 at 1145 UTC (7:45 a.m. EST). The image was created by the NASA GOES Project (in partnership with NOAA) at NASA's Goddard Space Flight Center in Greenbelt, Maryland.
GREENBELT, Md. -- The cleanroom at NASA's Goddard Space Flight Center in Greenbelt, Md. has received a giant structural steel frame that will be used to assemble the mirrors and instruments of the James Webb Space Telescope.
"This milestone is important as it marks the transition to the integration and testing phase for the Webb telescope's optical telescope element," said Lee Feinberg, Optical Telescope Element Manager for the Webb telescope at Goddard.
New observations by NASA's Hubble Space Telescope are expanding astronomers' understanding of the ways in which galaxies continuously recycle immense volumes of hydrogen gas and heavy elements. This process allows galaxies to build successive generations of stars stretching over billions of years.
This ongoing recycling keeps some galaxies from emptying their "fuel tanks" and stretches their star-forming epoch to over 10 billion years.
AMHERST, Mass. – New, high-precision equipment orbiting Earth aboard the Hubble Space Telescope is now sending such rich data back to astronomers, some feel they are crossing the final frontier toward understanding galaxy evolution, says Todd Tripp, leader of the team at the University of Massachusetts Amherst.
New details about the birth of a famous black hole that took place millions of years ago have been uncovered, thanks to a team of scientists who used data from NASA's Chandra X-ray Observatory as well as from radio, optical and other X-ray telescopes.
For the first time, astronomers have produced a complete description of a black hole, a concentration of mass so dense that not even light can escape its powerful gravitational pull. Their precise measurements have allowed them to reconstruct the history of the object from its birth some six million years ago.
[San Francisco, CA] – A new study, led by PRBO Conservation Science (PRBO), projects a bleak future for San Francisco Bay's tidal marshes under high-end sea-level rise scenarios that are increasingly likely. PRBO and colleagues found that in the worst case scenario 93% of San Francisco Bay's tidal marsh could be lost in the next 50-100 years [with 5.4 feet or 1.65 meters of sea-level rise, low sediment availability and no significant restoration].
Speaking at the URSULA (Urban River Corridors and Sustainable Living Agendas) Conference, in Sheffield, Dr Abigail Hathway, of the University of Sheffield, will demonstrate how rivers can cool their local environment. Urban areas suffer increased temperatures as a result of traffic, air-conditioning systems and modern building materials which can absorb and re-radiate heat from the sun.
CHICAGO --- A new study that takes a complete snapshot of adolescent cardiovascular health in the United States reveals a dismal picture of teens who are likely to die of heart disease at a younger age than adults do today, reports Northwestern Medicine research.
MADISON – A new report published by an independent global commission of eminent scientists states that the world's food system needs an immediate transformation to meet current and future threats to food security and environmental sustainability.
The Commission on Sustainable Agriculture and Climate Change today released a Summary for Policy Makers that recommends crucial policy responses to the global challenge of feeding the world in the face of climate change, population growth, poverty, food price spikes and degraded ecosystems.
Using the LABOCA camera on the Atacama Pathfinder Experiment (APEX) telescope on the plateau of Chajnantor in the Chilean Andes, a team of astronomers led by Thomas Preibisch (Universitats-Sternwarte Munchen, Ludwig-Maximilians-Universitat, Germany), in close cooperation with Karl Menten and Frederic Schuller (Max-Planck-Institut fur Radioastronomie, Bonn, Germany), imaged the region in submillimetre light. At this wavelength, most of the light seen is the weak heat glow from cosmic dust grains.
University of Houston Green Building Components (UHGBC), a program in the Gerald D. Hines College of Architecture, announces its third annual UHGBC Expo. This event showcases the work of faculty-led research teams that design, develop and commercialize green building components and sustainable technologies for the built environment.
The exhibition runs 5 - 8 p.m., Nov. 17 in the College of Architecture's atrium. The event is free and open to the public. For more information, visit www.UHGBC.org.
ARLINGTON, Va.—In partnership with the Office of Naval Research (ONR), Marines at Camp Smith, Hawaii, are testing a high-tech trash disposal system that can reduce a standard 50-gallon bag of waste to a half-pint jar of harmless ash.
Called the Micro Auto Gasification System (MAGS), the unit is currently undergoing evaluation by U.S. Marine Corps Forces, Pacific (MARFORPAC) as a possible solution to help Marines win their daily battle against the increasing trash at remote forward operating bases (FOB).
Some of the oldest stars in the Milky Way – a kind of stellar fossils in the outer reaches of our galaxy, contain abnormally large amounts of heavy elements like gold, platinum and uranium. Where these large amounts came from has been a mystery for researchers, since they are usually seen in much later generations of stars.
