Pulsars have a number of unusual qualities. Like zombies, they shine even though they’re technically dead, and they rotate rapidly, emitting powerful and regular beams of radiation that are seen as flashes of light, blinking on and off at intervals from seconds to milliseconds. A NASA team has built a first-of-a-kind testbed that simulates these distinctive pulsations.
A team of scientists recently launched 20 balloons during a campaign in Antarctica to study a space weather phenomenon, during which electrons stream down toward the poles from two gigantic donuts of radiation, the Van Allen Belts, which surround Earth.
When did the first stars and galaxies form in the universe? How brightly did they burn their nuclear fuel? Scientists will seek to gain answers to these questions with the launch of the Cosmic Infrared Background ExpeRIment (CIBER) on a Black Brant XII suborbital sounding rocket between 11 and 11:59 p.m. EDT, June 4 from the Wallops Flight Facility in Virginia.
NASA's Mars rover Curiosity has used the drill on its robotic arm to collect a powdered sample from the interior of a rock called "Cumberland."
A new study of glaciers worldwide using observations from two NASA satellites has helped resolve differences in estimates of how fast glaciers are disappearing and contributing to sea level rise.
How many rings do you see in this new image of the galaxy Messier 94 (below), also known as NGC 4736? While at first glance one might see a number of them, astronomers believe there is just one. This particular image was captured in infrared light by NASA's Spitzer Space Telescope.
NASA's first mission to sample an asteroid is moving ahead into development and testing in preparation for its launch in 2016.
NASA and the U.S. Air Force Research Laboratory in Albuquerque, N.M., are requesting research and development proposals to define the type of spacecraft computing needed for future missions.
The director, a writer and some actors in the film "Star Trek Into Darkness" will join NASA as it hosts a Google+ Hangout from noon to 12:45 p.m. EDT, May 16, about how work aboard the International Space Station is turning science fiction into reality.
Gone are the days of being able to count the number of known planets on your fingers. Today, there are more than 800 confirmed exoplanets - planets that orbit stars beyond our sun - and more than 2,700 other candidates.
NASA's Hubble Space Telescope has found the building blocks for Earth-sized planets in an unlikely place - the atmospheres of a pair of burned-out stars called white dwarfs.
The roar of a 5,000 pound rocket engine has returned to the Johnson Space Center. The Morpheus team has completed the build-up of our “Bravo” vehicle, conducted numerous integrated tests, and has now stepped into our flight test program.
Completely surrounded by a massive 20-foot-high structure called the crew module static load test fixture, the Orion crew module is being put through a series of tests that simulate the massive loads the spacecraft would experience during its mission.
Our Milky Way galaxy is teeming with a wild variety of planets. In addition to our solar system's eight near-and-dear planets, there are more than 800 so-called exoplanets known to circle stars beyond our sun.
A NASA-led modeling study provides new evidence that global warming may increase the risk for extreme rainfall and drought.
A Chinese man who was suspected of spying on NASA was pulled off a plane with a stolen laptop. But instead of the expected state secrets, the laptop was packed full of porn.
NASA's Origins-Spectral Interpretation-Resource Identification-Security-Regolith Explorer (OSIRIS-REx) spacecraft will visit the asteroid now called Bennu, named after an important ancient Egyptian avian deity.
Earth’s atmosphere is critically important to all of us. In addition to providing us with air to breathe, it protects us from temperature extremes, harmful space radiation, and vast numbers of incoming meteoroids.
NASA's Cassini spacecraft has offered scientists the first close-up, visible-light views of a behemoth hurricane swirling around Saturn's north pole.
NASA's Cassini spacecraft recently managed to provide the first direct evidence of small meteoroids breaking into streams of rubble and crashing into Saturn's rings.
