The latest tropical storm in the western Pacific formed on Sunday, and is poised to make landfall in mainland China on Tuesday, near typhoon strength (74 mph). Two NASA satellites captured different views of its clouds.
NASA's Aqua satellite flew over the remnants of Fred, September 13 and captured an infrared and visible image of the storm's clouds from the Atmospheric Infrared Sounder (AIRS) instrument. Both AIRS images showed Fred's clouds stretched from northeast to southwest and resembled a tilted exclamation mark.
Cambridge, Mass. -- September 10, 2009 -- A team of environmental scientists from Harvard and Tsinghua University demonstrated the enormous potential for wind-generated electricity in China.
Linda managed to power up to hurricane status at 11 p.m. EDT last night (September 9), and she's running into cooler waters and wind shear, so she's not expected to hold that strength through tomorrow. Microwave imagery from NASA's Aqua satellite revealed a 10 percent opening in her eyewall and that's a clue that the storm can weaken.
"This is one more important step in the confirmation of this wonderful mission. We Europeans are proud to be part of this and heartily congratulate the engineers, astronauts and scientists who got us to this point," said ESA's Director of Science and Robotic Exploration, David Southwood.
Scientists at the Naval Research Laboratory (NRL) Space Science Division and a team of international researchers have positively identified cosmic sources of gamma-ray emissions through the discovery of 16 pulsating neutron stars.
University of Hawaii astronomer Dr. Tomotsugu Goto and colleagues have discovered a giant galaxy surrounding the most distant black hole ever found. The galaxy, which is 12.8 billion light-years from Earth, is as large as the Milky Way galaxy and harbors a supermassive black hole that contains at least a billion times as much matter as does our sun.
This summer, a group of scientists and students -- as well as a Canadian senator, a writer, and a filmmaker -- set out from Resolute Bay, Canada, on the icebreaker Louis S. St-Laurent. They were headed through the Northwest Passage, but instead of opening shipping lanes in the ice, they had gathered to open up new lines of thinking on Arctic science.
Lakes in Antarctica, concealed under miles of ice, require scientists to come up with creative ways to identify and analyze these hidden features. Now, researchers using space-based lasers on a NASA satellite have created the most comprehensive inventory of lakes that actively drain or fill under Antarctica's ice.
It's unusual to see towering clouds that are created from smoke and fires, but that's what showed up in the latest satellite imagery from NASA, when also capturing powerful Hurricane Jimena and Tropical Depression Kevin in the Eastern Pacific Ocean. Jimena's outer rainbands were already spreading over southern Baja California at 11 a.m. EDT.
Scientists using a continent-wide array of radio telescopes have made an extremely precise measurement of the curvature of space caused by the Sun's gravity, and their technique promises a major contribution to a frontier area of basic physics.
Hurricane Warnings are up for the southern Baja California, as powerful Category Four Hurricane Jimena threatens. Jimena developed over the weekend, and the infrared instrument on NASA's Aqua satellite captured that explosive development.
GREENBELT, Md. --The dust-filled disks where new planets may be forming around other stars occasionally take on some difficult-to-understand shapes. Now, a team led by John Debes at NASA's Goddard Space Flight Center in Greenbelt, Md., finds that a star's motion through interstellar gas can account for many of them.
NASA's GOES Project has been busy with animating satellite imagery of Tropical Storm Danny, and has created a movie of him from August 25-27.
NASA satellite imagery and aircraft data revealed Tropical Storm Danny's center reformed a little farther north than it was yesterday. The center of his circulation is "broad and elongated" so it's been somewhat challenging to pinpoint his center. The National Hurricane Center used NASA QuikScat data to confirm winds early this morning.
