NASA Missions Catch First Light from a Gravitational-Wave Event
For the first time, NASA scientists have detected light tied to a gravitational-wave event, thanks to two merging neutron stars in the galaxy NGC 4993, located about 130 million light-years from Earth in the constellation Hydra.
Media Invited to View NASA Spacecraft That Will Touch Our Sun
NASA’s Parker Solar Probe will be humanity’s first-ever mission to explore the Sun’s outer atmosphere. Media are invited to see the spacecraft and learn about the mission from noon to 2 p.m. EDT Monday, Sept. 25, at Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Maryland, where the probe is being built.
NASA’s Cassini Spacecraft Ends Its Historic Exploration of Saturn
A thrilling epoch in the exploration of our solar system came to a close today, as NASA's Cassini spacecraft made a fateful plunge into the atmosphere of Saturn, ending its 13-year tour of the ringed planet.
NASA Announces Cassini End-of-Mission Media Activities
On Sept. 15, NASA's Cassini spacecraft will complete its remarkable story of exploration with an intentional plunge into Saturn's atmosphere, ending its mission after nearly 20 years in space.
NASA Selects Proposals to Study Galaxies, Stars, Planets
NASA has selected six astrophysics Explorers Program proposals for concept studies. The proposed missions would study gamma-ray and X-ray emissions from clusters of galaxies and neutron star systems, as well as infrared emissions from galaxies in the early universe and atmospheres of exoplanets, which are planets outside of our solar system.
Cassini to Begin Final Five Orbits Around Saturn
NASA's Cassini spacecraft will enter new territory in its final mission phase, the Grand Finale, as it prepares to embark on a set of ultra-close passes through Saturn’s upper atmosphere with its final five orbits around the planet.
NASA Recommends Safety Tips to View the August Solar Eclipse
More than 300 million people in the United States potentially could directly view the Aug. 21 total solar eclipse, and NASA wants everyone who will witness this celestial phenomenon to do so safely.
NASA’s Voyager Spacecraft Still Reaching for the Stars After 40 Years
Humanity’s farthest and longest-lived spacecraft, Voyager 1 and 2, achieve 40 years of operation and exploration this August and September. Despite their vast distance, they continue to communicate with NASA daily, still probing the final frontier.
NASA Selects Proposals to Study Sun, Space Environment
NASA has selected nine proposals under its Explorers Program that will return transformational science about the Sun and space environment and fill science gaps between the agency’s larger missions; eight for focused scientific investigations and one for technological development of instrumentation.
