(NASA/Goddard Space Flight Center) Data from NASA's AIM spacecraft shows the sky over Antarctica is glowing electric blue due to the start (an early one) of noctilucent, or night-shining, cloud season in the Southern Hemisphere.
(NASA/Goddard Space Flight Center) The sun may seem static from Earth's vantage point, 93 million miles away, but our star is constantly changing. Complex magnetic interactions force material throughout the solar atmosphere that can burst forth in massive eruptions. NASA's recently extended IRIS mission watches the interface region, the lower levels of the sun's atmosphere.
(NASA/Goddard Space Flight Center) NASA's Aqua satellite flew over Tropical Cyclone Nada in the Northern Indian Ocean and infrared imagery showed that Nada had 'nada' in terms of strong thunderstorms.
(NASA/Goddard Space Flight Center) The Global Precipitation Measurement mission or GPM core satellite gathered rainfall data on the severe storms that impacted the southeastern US over two days. From Tuesday evening, Nov. 29 through Wednesday morning, Nov. Show More Summary
(NASA/Goddard Space Flight Center) NASA-NOAA's Suomi NPP satellite revealed that wind shear was affecting Tropical Cyclone Nada in the Northern Indian Ocean.
(NASA/Goddard Space Flight Center) Tropical Cyclone Tokage fell apart after crossing the Philippines and moving into the South China Sea where wind shear battered the storm. NASA's Aqua satellite took a visible picture of the storm as it was being torn apart on Nov. 28.
(NASA/Goddard Space Flight Center) Operation IceBridge, NASA's airborne survey of changes in polar ice, is closing in on the end of its eighth consecutive Antarctic deployment, and will likely tie its 2012 campaign record for the most research flights carried out during a single Antarctic season.
(NASA/Goddard Space Flight Center) Slow moving frontal systems draped over Hispaniola and a tropical wave recently caused heavy rainfall that led to wide spread flooding over the northern Dominican Republic. NASA analyzed that heavy rainfall using data from satellites.
(NASA/Goddard Space Flight Center) After Hurricane Sandy rocked the U.S. East Coast in 2012, the New York City government set out to repair the city -- and asked for NASA's help. The mayor's office didn't want NASA scientists out there with hammers or hard hats. Show More Summary
(NASA/Goddard Space Flight Center) Tropical Storm Tina was short-lived. NOAA's GOES-West satellite captured the remnants of the storm that formed, reached tropical storm status and fizzled in one day.
(NASA/Goddard Space Flight Center) High above Earth's surface, our magnetic field constantly deflects incoming ultra-fast particles from the sun. New THEMIS mission results show the acceleration of these particles can occur farther from Earth than previously thought, prompting more questions about what causes the speed-up.
(NASA/Goddard Space Flight Center) A late-season tropical storm named Tina formed offshore of the southwestern coast of Mexico on Sunday, Nov. 13 at 11 p.m. EST. It developed quickly from a tropical low pressure area previously designated as System 92E. A NASA animation of imagery from NOAA's GOES-West satellite shows Tina's development and weakening to depression status.
(NASA/Goddard Space Flight Center) Tropical Depression Ma-on formed on Nov. 10, 2016, northeast of Guam. Ma-on had maximum sustained winds estimated at 30 knots (34.5 mph) when the Global Precipitation Measurement mission or GPM core observatory satellite flew over.
(NASA/Goddard Space Flight Center) Dr. Colleen Hartman and Dr. Holly Gilbert of NASA's Goddard Space Flight Center in Greenbelt, Md., recently received awards for their contributions to the aerospace community.
(NASA/Goddard Space Flight Center) NASA's Magnetospheric Multiscale mission, or MMS, is breaking records. MMS now holds the Guinness World Record for highest altitude fix of a GPS signal.
(NASA/Goddard Space Flight Center) NGC 299 is an open star cluster located within the Small Magellanic Cloud just under 200,000 light-years away.
(NASA/Goddard Space Flight Center) Tropical Storm Meari is currently located 331 miles north of Ulithi which is an atoll in the Caroline Islands of the western Pacific Ocean. The storm has tracked northeastward at 7 knots per hour over the past six hours.
The optical and science segment of the largest space telescope ever now stands complete in the largest clean room on the planet, at NASA's Goddard Space Flight Center. Now poised to undergo rigorous pre-flight testing ahead of its 2018...Show More Summary
(NASA/Goddard Space Flight Center) Tropical Storm Meari began as a tropical depression numbered 26W north-northwest of Yap in the early morning hours of Nov. 3, 2016. Later that day it intensified into Tropical Storm Meari.
(NASA/Goddard Space Flight Center) Engineers and technicians working on the James Webb Space Telescope successfully completed the first important optical measurement of Webb's fully assembled primary mirror, called a Center of Curvature test.
