NASA's team that will conduct the first U.S. mission to collect samples from an asteroid has been given the go-ahead to begin building the spacecraft, flight instruments and ground system, and launch support facilities.
Until now, rings of material in a disc have only been observed around giant planets like Jupiter, Uranus, Neptune and especially Saturn, which is known for its spectacular rings.
A collage of radar images of near-Earth asteroid 2006 DP14 was generated by NASA scientists using the 230-foot (70-meter) Deep Space Network antenna at Goldstone, Calif., on the night of Feb. 11, 2014.
Scientists using CSIRO's Parkes telescope and another telescope in South Africa have found evidence that a tiny star called PSR J0738-4042 is being pounded by asteroids -- large lumps of rock from space.
One year ago the world was witness to the dangers presented by near-Earth Objects (NEOs) when a relatively small asteroid entered Earth's atmosphere, exploding over Chelyabinsk, Russia, and releasing more energy than a large atomic bomb.
ESO's New Technology Telescope (NTT) has been used to find the first evidence that asteroids can have a highly varied internal structure.
What's the best way get a sample of an asteroid? Play tag with it! That's the plan for OSIRIS-REx, a NASA spacecraft that will approach the asteroid Bennu in 2018. The collection will be done with an instrument on board called the Touch-And-Go Sample Acquisition Mechanism, or, TAGSAM. Learn how it works in this video.
Our solar system seems like a neat and orderly place, with small, rocky worlds near the Sun and big, gaseous worlds farther out, all eight planets following orbital paths unchanged since they formed.
Scientists using the Herschel space observatory have made the first definitive detection of water vapor on the largest and roundest object in the asteroid belt, Ceres.
