3 NASA satellites capture Typhoon Megi strengthening again
GOES-13 sees system 99L organizing tropically
The GOES-13 satellite keeps a continuous eye over the eastern U.S., the Caribbean Sea, Gulf of Mexico and Atlantic Ocean, and noticed that System 99L is much better organized today, October 20, hinting that it could become a tropical depression la…
GOES-13 on top of new seventeenth Atlantic (sub) tropical depression
The GOES-13 satellite keeps a vigilant eye on the Atlantic Ocean and eastern U.S. and this morning at 5 a.m. EDT it saw System 97L organize into the seventeenth tropical depression of the Atlantic Ocean season. The only catch is that it is actua…
GOES-13 sees another potential tropical depression in Caribbean Sea
The GOES-13 satellite passed over a low pressure area designated as “System 97L” earlier today and captured a visible image of the low in the eastern Caribbean Sea. System 97L appears in a good place for development into a tropical depression …
NASA’S Mars atmosphere mission given the green light to proceed to development
GREENBELT, Md. — NASA’s mission to investigate the mystery of how Mars lost much of its atmosphere passed a critical milestone on October 4, 2010. NASA has given approval for the development and 2013 launch of the Mars Atmosphere and Volatil…
TRMM satellite sees tropical moisture bring heavy rain, flooding to US East Coast
A deep, stationary trough of low pressure parked over the Ohio and Tennessee valleys west of the Appalachians drew a steady stream of tropical moisture, including the remnants of Tropical Storm Nicole, up the East Coast. The results were heavy…
Cluster helps disentangle turbulence in the solar wind
From Earth, the Sun looks like a calm, placid body that does little more than shine brightly while marching across the sky. Images from a bit closer, of course, show it’s an unruly ball of hot gas that can expel long plumes out into space — …
Goddard team obtains the ‘unobtainium’ for NASA’s next space observatory
Imagine building a car chassis without a blueprint or even a list of recommended construction materials. In a sense, that’s precisely what a team of engineers at the NASA Goddard Space Flight Center in Greenbelt, [...]
GOES-13 sees a weaker Hurricane Julia in the ‘tropical trio’
GOES-13 satellite imagery this morning showed the “tropical trio”: Tropical Storm Karl over the Gulf of Mexico, Hurricane Igor in the central Atlantic, and a waning Hurricane Julia in the eastern Atlantic Ocean. Hurricane Julia has now lost her …
NASA’s 3-D look into Hurricane Igor’s heavy rainfall
NASA’s Tropical Rainfall Measuring Mission (TRMM) satellite has provided a 3-D look at the power “under the hood” (of clouds) in powerful Category 4 Hurricane Igor as it heads toward Bermuda. In the meantime, Igor is creating dangerous surf in t…
GOES-13 sees system 92L looking more like a tropical depression
GOES-13 captured a look at System 92L this morning as it continues moving through the central Caribbean, and it’s looking more and more like a tropical depression.
As the Geostationary Operational Environmental Satellite called GOES-13 satelli…
NASA satellite data aid United Nations’ ability to detect global fire hotspots
In the midst of a difficult fire season in many parts of the world, the United Nations’ (UN) Food and Agriculture Organization has launched a new online fire detection system that will help firefighters and natural hazards managers improve response …
Bermuda in warnings as the GOES-13 Satellite catches Fiona approaching
Bermuda has warnings up as Tropical Storm Fiona approaches, and GOES-13 satellite imagery from today shows that Fiona, although packing a punch, is a much smaller system that her brother, the Category 4 Hurricane Earl.
A tropical storm warni…
NASA and NOAA’s newest GOES satellite ready for action
GREENBELT, Md. — NASA and NOAA’s latest Geostationary Operational Environmental Satellite, GOES-15, has successfully completed five months of on-orbit testing and has been accepted into service. The satellite has demonstrated operational read…
GOES-13 catches 3 tropical cyclones thrashing through the Atlantic
Powerful Hurricane Earl, growing Tropical Storm Fiona and fading Danielle were all captured in today’s visible image from the GOES-13 satellite. The Geostationary Operational Environmental Satellite called GOES-13 captured an image of the busy…
NASA’s LRO reveals ‘incredible shrinking moon’
GREENBELT, Md. — Newly discovered cliffs in the lunar crust indicate the moon shrank globally in the geologically recent past and might still be shrinking today, according to a team analyzing new images from NASA’s Lunar Reconnaissance Orbiter …
NASA satellites see TD5′s remnants still soaking Louisiana and Mississippi
Tropical Depression Five’s remnants continue to linger over Louisiana and Mississippi, and NASA satellite data continues to capture its cloud temperatures and extent. The slow moving remnants and an associated tropical air mass are expected to c…
NASA study finds increasing solar trend that can change climate
Since the late 1970s, the amount of solar radiation the sun emits, during times of quiet sunspot activity, has increased by nearly .05 percent per decade, according to a new NASA funded study. “This trend is important because, if sustained over many decades, it could cause significant climate change,” said Richard Willson, a researcher affiliated with NASA’s Goddard Institute for Space Studies and Columbia University’s Earth Institute, New York. He is the lead author of the study recently published in Geophysical Research Letters. “Historical records of solar activity indicate that solar radiation has been increasing since the late 19th century. If a trend, comparable to the one found in this study, persisted throughout the 20th century, it would have provided a significant component of the global warming the Intergovernmental Panel on Climate Change reports to have occurred over the past 100 years,” he said.
Climate changes may increase extreme rain/snow events in California
Increasing carbon dioxide levels in the atmosphere may lead to a rise in the number of annual extreme precipitation events in the Sierra Nevada Mountains, which in turn could increase the frequency of flooding in California, a NASA-funded study finds.
NASA-funded research looking at El Ni?o events to forecast western US snowfall
A NASA-funded study uses a computer model to understand an observed link between winter and spring snowfall in the Western U.S. and El Ni?o Southern Oscillation. Almost 75 to 85 percent of water resources in the Western U.S come from snow that accumulates in the winter and early spring and melts as runoff in spring and summer. Understanding this connection and using it to predict future snowfall rates would greatly help both citizens and policy makers.
The Oldest Light in the Universe
NASA today released the best “baby picture” of the Universe ever taken; the image contains such stunning detail that it may be one of the most important scientific results of recent years. Scientists used NASA’s Wilkinson Microwave Anisotropy Probe (WMAP) to capture the new cosmic portrait, which reveals the afterglow of the big bang, a.k.a. the cosmic microwave background.
NASA satellite helps scientists see effects of earthquakes in remote areas
The unique capabilities of a NASA earth-observing satellite have allowed researchers to view the effects of a major earthquake that occurred in 2001 in Northern India near the border of Pakistan. Lead author Bernard Pinty of the Institute for Environment and Sustainability in the Joint Research Centre of the European Commission, Ispra, Italy, and colleagues from the U.S., France and Germany, used the Multi-angle Imaging SpectroRadiometer (MISR) instrument on NASA’s Terra satellite to observe the effects of a massive earthquake in the Gujarat province of India.
NASA Research Offers Explanation for Earth’s Bulging Waistline
A team of researchers from NASA’s Jet Propulsion Laboratory, Pasadena, Calif., and the Royal Observatory of Belgium has apparently solved a recently observed mystery regarding changes to the physical shape of Earth and its gravity field. The answer, they found, appears to lie in the melting of sub-polar glaciers and mass shifts in the Southern, Pacific and Indian Oceans associated with global-scale climate changes.
