(NASA/Goddard Space Flight Center) Now in 2017, inspired by the event in Boulder, NASA scientists will explore the moon's eclipse of the sun to learn more about Earth's energy system.
(NASA/Goddard Space Flight Center) Hubble captured the tiny moon Phobos during its orbital trek around Mars: so small, it appears star-like in the Hubble pictures.
(NASA/Goddard Space Flight Center) As of 5 a.m. July 20 (0900 UTC), Fernanda had weakened to tropical storm status. There are no coastal watches or warnings in effect.
(NASA/Goddard Space Flight Center) Hurricane Fernanda appears to be weakening on infrared satellite imagery. NOAA's GOES-West satellite imagery on July 19 showed a more disorganized hurricane nearing the Central Pacific Ocean.
(NASA/Goddard Space Flight Center) Tropical Storm Don didn't live long before it weakened to a remnant low pressure area in the North Atlantic Ocean.
(NASA/Goddard Space Flight Center) The Neutron star Interior Composition Explorer, or NICER, payload completed commissioning and calibration and all systems are working as expected.
(NASA/Goddard Space Flight Center) NASA's Van Allen Probes have observed a new population of space sound waves, called plasmaspheric hiss, which are important in removing high-energy particles from around Earth that can damage satellites.
(NASA/Goddard Space Flight Center) One night three months ago, Rosa Castro finished her dinner, opened her laptop, and uncovered a novel object that was neither planet nor star. Therapist by day and amateur astronomer by night, Castro...Show More Summary
(NASA/Goddard Space Flight Center) Heavy rain resulted in significant flooding in the U.S. Midwest over the week of July 7 to 14, 2017. Using satellite data, NASA estimated the amount of rain that fell over those areas and used satellite data to create 3-D imagery of severe storms.
(NASA/Goddard Space Flight Center) Discovered by British astronomer William Herschel over 200 years ago, NGC 2500 lies about 30 million light-years away in the northern constellation of Lynx. As this NASA/ESA Hubble Space Telescope image shows, NGC 2500 is a particular kind of spiral galaxy known as a barred spiral, its wispy arms swirling out from a bright, elongated core.
(NASA/Goddard Space Flight Center) Hurricane Fernanda is moving through the deep tropics and there's nothing in its way to prevent it from becoming a major hurricane. NASA's Terra satellite took a closer look at the strengthening st...
(NASA/Goddard Space Flight Center) Tropical Storm Fernanda continues to strengthen as it moves west through the Eastern Pacific Ocean. NOAA's GOES-West satellite provided an infrared image of the storm on July 13 as it was nearing hurricane strength.
(NASA/Goddard Space Flight Center) The sixth tropical depression of the Eastern Pacific Ocean hurricane season formed near southwestern Mexico and quickly strengthened into Tropical Storm Fernanda. NASA's Aqua satellite provided infrared imagery of the strengthening storm.
(NASA/Goddard Space Flight Center) Tropical Storm Eugene has been moving over cooler sea surface temperatures that have been sapping its strength. The Global Precipitation Measurement mission, or GPM, core satellite passed over Eugene and measured its decreasing rainfall rates.
(NASA/Goddard Space Flight Center) An iceberg about the size of the state of Delaware split off from Antarctica's Larsen C ice shelf sometime between July 10 and July 12, 2017.
NASA is developing a new instrument to expand the boundaries of astronomy research. A team of scientists and technologists at NASA's Goddard Space Flight Center (GSFC) is developing the High-Resolution Mid-Infrared Spectrometer (HIRMES)—an...Show More Summary
(NASA/Goddard Space Flight Center) A new sunspot group has rotated into view and seems to be growing rather quickly in this video captured by NASA's Solar Dynamics Observatory between July 5-11, 2017.
(NASA/Goddard Space Flight Center) Arctic winter warming events -- winter days where temperatures peak above 14 degrees Fahrenheit (minus 10 degrees Celsius) -- are a normal part of the climate over the ice-covered Arctic Ocean. ButShow More Summary
(NASA/Goddard Space Flight Center) NASA satellites gave the Eastern Pacific Ocean's Hurricane Eugene an 'eye exam' as it studied the storm in infrared and visible light. NASA satellite imagery taken at different times showed Eugene's eye open and closed.
(NASA/Goddard Space Flight Center) NASA satellite imagery revealed that Tropical Depression 4 appears to be losing its punch, and the National Hurricane Center expects the storm to weaken.
