(NASA/Goddard Space Flight Center) The fourth tropical cyclone of the Eastern Pacific Ocean season formed on June 25 and by June 26 it was already a hurricane. NASA-NOAA's Suomi NPP satellite passed over Dora on June 25 when it was a tropical storm and the next day it became the first hurricane of the season.
(NASA/Goddard Space Flight Center) For the first time, a computer simulation -- so detailed it took a full year to run -- shows how spicules form, helping scientists understand how spicules can break free of the sun's surface and surge upward so quickly.
(NASA/Goddard Space Flight Center) Tropical storm Cindy was downgraded to a tropical depression after moving onshore near the Texas and Louisiana Border on Thursday June 22, 2017 and bringing a lot of rain with it. That rainfall was measured by NASA using satellite data.
(NASA/Goddard Space Flight Center) The NASA-funded CHESS mission will check out the interstellar medium, peering into floating clouds of atoms and molecules that over millions of years may evolve into new stars.
(NASA/Goddard Space Flight Center) NASA's James Webb Space Telescope was placed in Johnson Space Center's historic Chamber A on June 20, 2017, to prepare for its final three months of testing in a cryogenic vacuum that mimics temperatures in space.
(NASA/Goddard Space Flight Center) By combining the power of a 'natural lens' in space with the capability of NASA's Hubble Space Telescope, astronomers made a surprising discovery -- the first example of a compact yet massive, fast-spinning, disk-shaped galaxy that stopped making stars only a few billion years after the big bang.
(NASA/Goddard Space Flight Center) NASA's Aqua satellite captured an image of Tropical Storm Cindy after it formed and was already affecting the US Gulf Coast states. Cindy continues to crawl toward land and Tropical Storm warnings are in effect for June 21.
(NASA/Goddard Space Flight Center) Tropical Storm Bret was weakening with NASA-NOAA's Suomi NPP satellite passed overhead on June 20, and within three hours of the overpass, Bret degenerated into a tropical wave.
(NASA/Goddard Space Flight Center) NASA's Global Precipitation Measurement mission or GPM core satellite passed over a developing low pressure area in the Gulf of Mexico and gathered two days of rainfall and storm height information. The disturbance could become Tropical or Sub-tropical Storm Cindy in the next couple days.
(NASA/Goddard Space Flight Center) NASA provided rainfall data and cloud height information to the forecasters monitoring the developing Tropical Cyclone 2 in the western Atlantic Ocean. The Global Precipitation Measurement mission or GPM core satellite passed over the organizing storm on June 19. Show More Summary
(NASA/Goddard Space Flight Center) At least 156 people in Bangladesh were killed during the past week by landslides and floods caused by heavy rainfall. NASA calculated the amount of rain that has fallen using data from satellites.
(NASA/Goddard Space Flight Center) Since its launch in November 2013 and its orbit insertion in September 2014, MAVEN has been exploring the upper atmosphere of Mars. MAVEN is bringing insight to how the sun stripped Mars of most of its atmosphere, turning a planet once possibly habitable to microbial life into a barren desert world.
(NASA/Goddard Space Flight Center) Tropical Depression 3E briefly strengthened into a tropical storm and was renamed Calvin before it made landfall in southwestern Mexico. NASA's Aqua satellite captured a look at the depression just prior to its classification as a tropical storm.
(NASA/Goddard Space Flight Center) Tropical Storm Merbok formed in the South China Sea early on June 11 and NASA-NOAA's Suomi NPP satellite passed overhead as the storm moved toward China on June 12.
(NASA/Goddard Space Flight Center) The third tropical cyclone of the Eastern Pacific Ocean hurricane season formed on Sunday, June 11 at 5 a.m. EDT about 120 miles (190 km) south of Salina Cruz, Mexico. Tropical Depression 3E moved north and turned to the northwest, slowly tracking toward land. Satellite imagery from NASA and NOAA show that the system appears elongated.
(NASA/Goddard Space Flight Center) This seemingly unspectacular series of dots with varying distances between them actually shows the slow waltz of two brown dwarfs. The image is a stack of 12 images made over the course of three years with the NASA/ESA Hubble Space Telescope. Show More Summary
(NASA/Goddard Space Flight Center) Astronomers have used the sharp vision of NASA's Hubble Space Telescope to repeat a century-old test of Einstein's general theory of relativity. The Hubble team measured the mass of a white dwarf, the burned-out remnant of a normal star, by seeing how much it deflects the light from a background star.
(NASA/Goddard Space Flight Center) Extremely heavy rain has recently fallen over Florida and the Global Precipitation Measurement or GPM mission core satellite looked at that some of that rainfall on June 7. Rainfall records were broken on that date as the GPM satellite passed overhead from space.
(NASA/Goddard Space Flight Center) Scientists make precise measurements of water clarity from satellite data, but the calculations can be hard to explain to the public. Now NASA is adopting a new way -- involving white sneakers -- to communicate water clarity.
(NASA/Goddard Space Flight Center) Is it a case of nature versus nurture when it comes to two 'cousin' exoplanets? In a unique experiment, scientists used NASA's Hubble Space Telescope to study two 'hot Jupiter' exoplanets. Because these...Show More Summary
