NASA's asteroid sample return spacecraft successfully used Earth's gravity on Friday to slingshot itself on a path toward the asteroid Bennu, for a rendezvous next August.
NASA's Hubble Space Telescope helped an international team of astronomers find that an unusual object in the asteroid belt is, in fact, two asteroids orbiting each other that have comet-like features. These include a bright halo of material, called a coma, and a long tail of dust.
With the help of the NASA/ESA Hubble Space Telescope, a German-led group of astronomers have observed the intriguing characteristics of an unusual type of object in the asteroid belt between Mars and Jupiter: two asteroids orbiting each other and exhibiting comet-like features, including a bright coma and a long tail. This is the first known binary asteroid also classified as a comet. The research is presented in a paper published in the journal Nature today.
A Brown University study identifies three large surface ice deposits near Mercury's north pole, and suggests there could be many additional small-scale deposits that would dramatically increase the planet's surface ice inventory.
River deposits exist across the surface of Mars and record a surface environment from over 3.5 billion years ago that was able to support liquid water at the surface. A region of Mars named Aeolis Dorsa contains some of the most spectacular and densely packed river deposits seen on Mars.
The Cassini-Huygens mission to Saturn, a collaboration between NASA and the European Space Agency, is set to end on Sept. 15. The mission has told us a great deal about the unique and unexpected chemistry of Saturn's moon Titan, and it has changed the way we think about our own planet and the entire solar system.

Three scientists at Niels Bohr Institute (NBI), University of Copenhagen, have carried out extensive computer simulations related to star formation. They conclude that the present idealized models are lacking when it comes to describing details in the star formation process. 'Hopefully our results can also help shed more light on planet formation', says Michael Küffmeier, astrophysicist and head of the research team.
Astronomers have discovered that the well-studied exoplanet WASP-12b reflects almost no light, making it appear essentially pitch black. This discovery sheds new light on the atmospheric composition of the planet and also refutes previous hypotheses about WASP-12b's atmosphere. The results are also in stark contrast to observations of another similarly sized exoplanet.
NASA's Hubble Space Telescope has observed a planet outside our solar system that looks as black as fresh asphalt.
Researchers at the University of York have shown that molecules brought to earth in meteorite strikes could potentially be converted into the building blocks of DNA.
