What is a black hole? How do we study them when we can???t see them? Astrophysicist Jeremy Schnittman from NASA???s Goddard Space Flight Center joins NASA Chief Scientist Jim Green for a fascinating conversation about the latest black hole research.
Dr. Stephanie Schollaert Uz of NASA's Goddard Space Flight Center in Greenbelt, Maryland, has been awarded the Arthur S. Flemming Award for Applied Science.
A pair of orbiting black holes millions of times the Sun???s mass perform a hypnotic dance in a new NASA visualization. The movie traces how the black holes distort and redirect light emanating from the maelstrom of hot gas ??? called an accretion disk ??? that surrounds each one.
The Nancy Grace Roman Space Telescope's microlensing survey also provide the best opportunity yet to definitively detect solitary stellar-mass black holes for the first time.
Data from NASA???s NICER telescope on the International Space Station have revealed X-ray surges accompanying radio bursts from the pulsar in the Crab Nebula. The finding shows that these bursts, called giant radio pulses, release far more energy than previously suspected.
Engineers working on NASA???s James Webb Space Telescope have successfully folded and packed its sunshield for its upcoming million-mile (roughly 1.5 million kilometer) journey, which begins later this year.
Early this morning, April 7, 2021, NASA's OSIRIS-REx mission completed its last flyover of near-Earth asteroid Bennu. OSIRIS-REx, with its pristine and precious asteroid sample cargo, will remain in the vicinity of Bennu until May 10, when it will fire its thrusters and begin its two-year cruise home.
NASA's Hubble Space Telescope is "seeing double." Peering back 10 billion years into the universe's past, Hubble astronomers found a pair of quasars that are so close to each other they look like a single object in ground-based telescopic photos, but not in Hubble???s crisp view.
NASA???s Lucy spacecraft has successfully completed thermal vacuum testing of both solar panels, the final step in checking out these critical spacecraft components in preparation for launch this fall. Once the Lucy spacecraft???s solar panels attached and fully extended, they could cover a five-story building.
With data from a 2016 expedition, scientists supported by NASA are shedding more light into the complex processes under the Greenland Ice Sheet that control how fast its glaciers slide toward the ocean and contribute to sea level rise.
The team of scientists and engineers behind NASA's Curiosity rover named a hill along the rover's path on Mars in honor of a recently deceased mission scientist.
Evaporation plays an important role in the global water and energy cycles and therefore in climate change. AIRS data were used in a study to help quantify evaporation over the Southern Ocean, where the Antarctic sea ice coverage has a large annual cycle.
On Apr. 7, the OSIRIS-REx spacecraft will get one last close encounter with Bennu as it performs a final flyover to capture images of the asteroid's surface.
Scientists predict that the data collected for Roman's microlensing survey will provide an additional bounty of roughly 100,000 transiting planets, worlds that periodically dim the light of their stars as they cross in front of them.
Sea ice in the Arctic appears to have hit its annual maximum extent after growing through the fall and winter. This year's maximum extent peaked at 5.70 million square miles, making it the seventh-smallest on record and tied with 2007.
