(NASA/Goddard Space Flight Center) The area of tropical low pressure designated System 91P appears to be organizing in NASA satellite imagery on March 24. Visible imagery from NASA-NOAA's Suomi NPP satellite revealed that the tropical low is consolidating and strengthening in the Coral Sea, South Pacific Ocean.
(NASA/Goddard Space Flight Center) Tropical cyclone Caleb formed on March 23 in the South Indian Ocean southwest of the Indonesian Island of Sumatra. The GPM core observatory satellite had a fairly good view of the newly formed tropical cyclone when it flew overhead and analyzed its rainfall and found the heaviest precipitation was affected by westerly winds.
(NASA/Goddard Space Flight Center) OSIRIS-REx did not discover any Earth-Trojan asteroids during a two-week search, but the spacecraft's cameras operated flawlessly and demonstrated they can image objects two magnitudes dimmer than originally expected.
(NASA/Goddard Space Flight Center) The Global Precipitation Measurement mission or GPM constellation of satellites provide data on precipitation rates and totals. Recently the GPM core observatory measured the heavy rainfall that caused extensive flooding and loss of life in Peru.
(NASA/Goddard Space Flight Center) Shortly after Tropical Cyclone Caleb formed east of Cocos Island, NASA-NOAA's Suomi NPP satellite and NASA's Aqua satellite passed overhead gathering visible and infrared data on the twelfth tropical cyclone of the Southern Indian Ocean season.
(NASA/Goddard Space Flight Center) NOAA's GOES-16 satellite is ready to embark on another major milestone-- The GOES-16 Field Campaign. During a three month long event, a combination of NOAA and NASA planes, sensors and satellites will fine-tune GOES-16's brand new instruments.
(NASA/Goddard Space Flight Center) Astronomers have uncovered a supermassive black hole that has been propelled out of the center of a distant galaxy by what could be the awesome power of gravitational waves.
(NASA/Goddard Space Flight Center) The Arctic sea ice maximum extent and Antarctic minimum extent are both record lows this year. Combined, sea ice numbers are at their lowest point since satellites began to continuously measure sea ice in 1979.
On March 7, 2017, the sea ice reached its wintertime extent and is officially the “lowest ever recorded by satellites at the end of summer in the Southern Hemisphere,” according to NASA’s Goddard Space Flight Center.
(NASA/Goddard Space Flight Center) NASA is developing a trailblazing, long-term technology demonstration of what could become the high-speed internet of the sky. Laser communication offers data rates that are 10 to 100 times better than current radio-frequency systems.
(NASA/Goddard Space Flight Center) A hybrid computing system developed at NASA's Goddard Space Flight Center in Greenbelt, Maryland, is the enabling technology behind an ambitious experiment testing a relative navigation and autonomous docking capability known as Raven.
(NASA/Goddard Space Flight Center) Arsia Mons produced one new lava flow at its summit every 1 to 3 million years during the final peak of activity, about 50 million years ago.
(NASA/Goddard Space Flight Center) Astronomers measured the light produced when a sun-like star wandered too close to a 3-million-solar-mass black hole similar to the one at the center of our own galaxy.
(NASA/Goddard Space Flight Center) Hubble caught a cross-section of NGC 1448, a spiral galaxy located about 50 million light-years from Earth.
(NASA/Goddard Space Flight Center) A gravitational tussle, ended with a multi-star system breaking apart and at least three stars being ejected in different directions.
(NASA/Goddard Space Flight Center) Ex-tropical cyclone 11S was still generating some heavy rainfall, despite losing its tropical status and becoming a sub-tropical storm when the GPM core satellite passed overhead. The Global Precipitation Measurement mission or GPM core satellite passed over the remnant low pressure area and analyzed the rain the system was generating.
(NASA/Goddard Space Flight Center) Earth's radiation belts, two doughnut-shaped regions of charged particles encircling our planet, were discovered more than 50 years ago, but their behavior is still not completely understood. Now, new...Show More Summary
(NASA/Goddard Space Flight Center) Once a tropical storm, now a sub-tropical storm, the remnants of the tropical low pressure area formerly known as 11S was spotted by NASA's Aqua satellite, still spinning in the Southern Indian Oce...
(NASA/Goddard Space Flight Center) The technicians who are inspecting the telescope and its expansive golden mirrors look like ghostly wraiths in this image as they conduct a 'lights out inspection' in the Spacecraft Systems Development and Integration Facility (SSDIF) at NASA's Goddard Space Flight Center in Greenbelt, Md.
(NASA/Goddard Space Flight Center) NASA and NOAA satellites are providing various views of the major winter storm marching toward the US East coast on March 13. The storm is forecast to merge with another system and is expected to bring large snowfall totals from the Mid-Atlantic to New England.
