Most of what scientists know of Jupiter's moon Europa they have gleaned from a dozen or so close flybys from NASA's Voyager 2 spacecraft in 1979 and NASA's Galileo spacecraft in the mid-to-late 1990s.
Dr. Rinehart is hoping to change the way scientists study the stars. To do this he needs a group of interns…and one very large balloon.
Something big is about to happen on the sun. According to measurements from NASA-supported observatories, the sun's vast magnetic field is about to flip.
Drop whatever you're doing and watch this. NASA has released videos shot from onboard the Space Shuttle's Solid Rocket Boosters in the past, but you've never seen one prepared as masterfully as this. For one thing, the footage was shot in high definition, so the image is exceptionally clear.
The intensity of the jets of water ice and organic particles that shoot out from Saturn's moon Enceladus depends on the moon's proximity to the ringed planet, according to data obtained by NASA's Cassini spacecraft.
News: a 3D printer approved by NASA will be flown to the International Space Station next year so astronauts can print components, tools and equipment on-demand in space. Manufactured by Made in Space in collaboration with NASA’s Marshall Space Flight Center, the machine is the first 3D printer ...
For the first time since exoplanets, or planets around stars other than the sun, were discovered almost 20 years ago, X-ray observations have detected an exoplanet passing in front of its parent star.
NASA has selected 3D printing of biomaterials, such as arrays of cells, as one of the 12 proposals for study under Phase I of the NASA Innovative Advanced Concepts (NIAC) Program, which aims to turn science fiction into reality.
Scientists have discovered a massive particle accelerator in the heart of one of the harshest regions of near-Earth space, a region of super-energetic, charged particles surrounding the globe called the Van Allen radiation belts.
NASA scientists and an international team of researchers have found tropical ecosystems can generate significant carbon dioxide when temperatures rise, unlike ecosystems in other parts of the world.
The moment when a telescope first opens its doors represents the culmination of years of work and planning - while simultaneously laying the groundwork for a wealth of research and answers yet to come. It is a moment of excitement and perhaps even a little uncertainty.
NASA scientists have established a new way to use satellites to measure what's occurring inside plants at a cellular level.
Astronomers using NASA's Spitzer Space Telescope have observed what most likely are strong carbon dioxide emissions from Comet ISON ahead of its anticipated pass through the inner solar system later this year.
Astronomers using NASA's Hubble Space Telescope have determined the orbital motion of two distinct populations of stars in an ancient globular star cluster, offering proof they formed at different times and providing a rare look back into the Milky Way galaxy's early days.
Two NASA spacecraft, one studying the Saturn system, the other observing Mercury, are maneuvering into place to take pictures of Earth on July 19 and 20.
The latest drive by NASA's Curiosity Mars rover brought the total distance that the rover has driven on Mars to more than 1 kilometer. One kilometer is about 0.62 miles.
NASA's Hubble Space Telescope has discovered a new moon orbiting the distant blue-green planet Neptune, the 14th known to be circling the giant planet.
Two NASA spacecraft have provided the most comprehensive movie ever of a mysterious process at the heart of all explosions on the sun: magnetic reconnection. Magnetic reconnection happens when magnetic field lines come together, break apart and then exchange partners, snapping into new positions and releasing a jolt of magnetic energy.
