At the center of our galaxy, where an enormous black hole blasts out energy as it chows down on interstellar detritus while neighboring stars burst to life and explode. astronomers have discovered two exhaust channels -- dubbed the 'galactic center chimneys' -- that appear to funnel matter and energy away from the cosmic fireworks.
Tropical Cyclone Trevor appeared to have a cloud-filled eye in visible imagery from NASA-NOAA's Suomi NPP satellite.
NASA's Aqua satellite provided a view of Tropical Cyclone Veronica after it developed off the northern coast of Western Australia.
Scientists provide a possible cost-saving approach to temporarily mitigate data gap problems if anything goes wrong in space or during the launch.
A team of Arizona State University scientists has been using the latest space technology, combined with ground measurements, to assess the health of one of the nation's most important sources of underground water, a large aquifer system located in California's San Joaquin Valley.
A NASA spacecraft that will return a sample of a near-Earth asteroid named Bennu to Earth in 2023 made the first-ever close-up observations of particle plumes erupting from an asteroid's surface. Bennu also revealed itself to be more rugged than expected, challenging the mission team to alter its flight and sample collection plans, due to the rough terrain.
Research led by the University of Colorado Boulder is revealing the Alice in Wonderland-like physics that govern gravity near the surface of the asteroid Bennu.
VLA image shows the trail of a speeding pulsar pointing directly back at the center of the debris shell from the supernova that created it.
Astronomers have found a runaway pulsar hurtling through space at nearly 2.5 million miles an hour -- so fast it could travel the distance between Earth and the Moon in just 6 minutes.
A Southwest Research Institute-led team has discovered that the surface geology on asteroid Bennu is older than expected. Early observations of the near-Earth asteroid by NASA's OSIRIS-REx mission indicate a surface that is between 100 million and 1 billion years old.
