(NASA/Goddard Space Flight Center) Three decades ago, astronomers spotted one of the brightest exploding stars in more than 400 years. Since that first sighting, SN 1987A has continued to fascinate astronomers with its spectacular light show. To commemorate the supernova's 30th anniversary, new observations and a 3-D model are being released.
(NASA/Goddard Space Flight Center) Inside NASA's Goddard Space Flight Center in Greenbelt, Maryland the James Webb Space Telescope team completed the environmental portion of vibration testing and prepared for the acoustic test on the telescope.
(NASA/Goddard Space Flight Center) NASA has estimated rainfall from the Pineapple Express over the coastal regions southwestern Oregon and northern California from the series of storms in February, 2017.
(NASA/Goddard Space Flight Center) In just two years' time, a team of NASA engineers accomplished what some thought impossible: the group created a smaller, more capable 'brain' for smaller spacecraft.
(NASA/Goddard Space Flight Center) After a 12-day flight spent examining solar flares while tethered from an enormous balloon, the GRIPS telescope endured a one-year layover alone on the Antarctic snowscape before scientists could retrieve their hardware.
(NASA/Goddard Space Flight Center) NASA's Aqua satellite spotted Tropical Cyclone 08P as it was developing in the South Pacific Ocean. Tropical Cyclone 08P, or 08P formed east of Extra-tropical cyclone Bart.
(NASA/Goddard Space Flight Center) NASA's Aqua satellite spotted Tropical Cyclone Bart as it was transitioning into an extra-tropical cyclone in the South Pacific Ocean.
(NASA/Goddard Space Flight Center) NASA's Fermi Gamma-ray Space Telescope has found a signal at the center of the neighboring Andromeda galaxy that could indicate the presence of the mysterious stuff known as dark matter. The gamma-ray signal is similar to one seen by Fermi at the center of our own Milky Way galaxy.
(NASA/Goddard Space Flight Center) Tropical Cyclone Bart has developed in the Southern Pacific Ocean, and NASA's Aqua satellite captured an image of the storm early on Feb. 21.
(NASA/Goddard Space Flight Center) NASA-NOAA's Suomi NPP satellite captured a visible image of the Southern Pacific Ocean's newly formed tropical cyclone in the Gulf of Carpentaria. By the next day Alfred made landfall and weakened to a remnant low pressure area.
(NASA/Goddard Space Flight Center) A NASA-led team will kick off an ambitious airborne campaign to determine which combination of sensors would work best at collecting global snow-water measurements from space -- critical for understanding and managing the world's freshwater resources.

(NASA/Goddard Space Flight Center) NASA examined the heavy rainfall generated by Tropical Cyclone Dineo as it made landfall in Mozambique and NASA's Terra satellite spotted the storm's remnants over four countries.
(NASA/Goddard Space Flight Center) Satellite imagery captured the beginning of a chain of Eastern Pacific Ocean storms forecast to affect the US West Coast. A close-up satellite view show from Feb. 17 shows a large storm system affecting southern California, while a wider satellite view revealed a second storm system in the Central Pacific Ocean headed toward the east.
(NASA/Goddard Space Flight Center) Technically, this picture is merely a sidekick of the actual object of interest -- but space is bursting with activity, and this field of bright celestial bodies offers plenty of interest on its ow...
(NASA/Goddard Space Flight Center) Researchers have completed the first flights of a NASA-led field campaign that is targeting one of the biggest gaps in scientists' understanding of Earth's water resources: snow.
(NASA/Goddard Space Flight Center) Two new Earth science instruments are scheduled to make their way to the station Feb. 18 on the SpaceX Dragon capsule.
(NASA/Goddard Space Flight Center) NASA-NOAA's Suomi NPP satellite got a night-time view of former Tropical Cyclone Dineo over the southeastern coast of Mozambique. Warnings have already been posted in the northeastern region of South Africa as Dineo continues to track inland.
(NASA/Goddard Space Flight Center) You can help astronomers search for new worlds lurking in the outer reaches of our solar system and in neighboring interstellar space. NASA is inviting the public on the hunt through a new website, Backyard Worlds: Planet 9.
(NASA/Goddard Space Flight Center) When NASA's Aqua satellite passed over Tropical Cyclone Dineo in the Mozambique Channel on Feb. 15, the storm was centered just off the coast of Mozambique and moving toward landfall.
(NASA/Goddard Space Flight Center) Cracks in the Greenland Ice Sheet let one of its aquifers drain to the ocean, new NASA research finds. The aquifers, discovered only recently, are unusual in that they trap large amounts of liquid water within the ice sheet. Show More Summary
