By comparing infrared and X-ray background signals across the same stretch of sky, an international team of astronomers has discovered evidence of a significant number of black holes that accompanied the first stars in the universe.
Using data from NASA's Chandra X-ray Observatory and NASA's Spitzer Space Telescope, which observes in the infrared, researchers have concluded one of every five sources contributing to the infrared signal is a black hole.
Astronomers at NASA and Pennsylvania State University have used NASA's Swift satellite to create the most detailed ultraviolet light surveys ever of the Large and Small Magellanic Clouds, the two closest major galaxies.
The images include light ranging from 1,600 to 3,300 angstroms, which is a range of UV wavelengths largely blocked by Earth's atmosphere.
The NASA Lunar Atmosphere and Dust Environment Explorer (LADEE) arrived on June 4, 2013 at NASA’s Wallops Flight Facility to begin final processing for its trip to the moon later this year.
LADEE is a robotic mission that will orbit the moon to gather detailed information about the lunar atmosphere, conditions near the surface and environmental influences on lunar dust.
The Boeing Company of Houston, a NASA Commercial Crew Program (CCP) partner, recently performed wind tunnel testing of its CST-100 spacecraft and integrated launch vehicle, the United Launch Alliance (ULA) Atlas V rocket. The testing is part of NASA's Commercial Crew Integrated Capability (CCiCap) initiative, intended to make commercial human spaceflight services available for government and commercial customers.
Measurements taken by the Mars Science Laboratory mission, as it delivered Curiosity to Mars, are providing NASA with information needed to design systems to protect human explorers from radiation exposure.
The Radiation Assessment Detector (RAD) is the first instrument to measure the radiation environment during a Mars cruise mission from inside a spacecraft similar to potential human exploration spacecraft.
The closest approach of the asteroid occurred today at 4:59 p.m. EDT, when the asteroid was no closer than about 3.6 million miles (5.8 million kilometers), or about 15 times the distance between Earth and the moon.
Its next pass, on July 12, 2028 will be at a very safe 45 million miles (73 mil km).
NASA's Gravity Recovery and Interior Laboratory (GRAIL) mission has uncovered the origin of massive invisible regions that make the moon's gravity uneven, a phenomenon that affects the operations of lunar-orbiting spacecraft.
Because of GRAIL's findings, spacecraft on missions to other celestial bodies can navigate with greater precision in the future.
Through detailed analysis, researchers have confirmed their initial interpretation of pebble-containing slabs investigated by NASA's Mars rover Curiosity: They are part of an ancient streambed.
The rocks are the first ever found on Mars that contain streambed gravels. The sizes and shapes of the gravels embedded in these conglomerate rocks enabled researchers to calculate the depth and speed of the water that once flowed at this location.
Jaden Smith, star of Columbia Pictures' movie "After Earth," is featured in a new NASA public service announcement that describes the contributions of the agency's Earth science program to environmental awareness and exploration of our home planet.
The public service announcement features imagery from "After Earth" as well as animations of Earth data from 17 orbiting NASA satellites.
NASA astronaut Karen Nyberg, Russian Federal Space Agency cosmonaut Fyodor Yurchikhin and European Space Agency astronaut Luca Parmitano joined their Expedition 36 crewmates when the hatches between the Soyuz TMA-09M spacecraft and the International Space Station officially opened at 12:14 a.m. EDT.
