| NASA identifying candidate asteroids for redirect mission Posted: 11 Sep 2014 03:53 PM PDT NASA is on the hunt to add potential candidate target asteroids for the agency's Asteroid Redirect Mission (ARM). The robotic mission will identify, capture and redirect a near-Earth asteroid to a stable orbit around the moon. In the 2020s, astronauts will explore the asteroid and return to Earth with samples. This will test and advance new technologies and spaceflight experience needed to take humans to Mars in the 2030s. |
| Posted: 11 Sep 2014 03:27 PM PDT Scientists have found that the surface of comet 67P/Churyumov-Gerasimenko -- the target of study for the European Space Agency's Rosetta mission -- can be divided into several regions, each characterized by different classes of features. High-resolution images of the comet reveal a unique, multifaceted world. |
| Unraveling mysteries of the Venusian atmosphere Posted: 11 Sep 2014 03:07 PM PDT Underscoring the vast differences between Earth and its neighbor Venus, new research shows a glimpse of giant holes in the electrically charged layer of the Venusian atmosphere, called the ionosphere. The observations point to a more complicated magnetic environment than previously thought -- which in turn helps us better understand this neighboring, rocky planet. |
| Alien life search: Spotting atmospheric chemistry of alien worlds devoid of life Posted: 11 Sep 2014 03:07 PM PDT Astronomers searching the atmospheres of alien worlds for gases that might be produced by life can't rely on the detection of just one type, such as oxygen, ozone, or methane, because in some cases these gases can be produced non-biologically, according to extensive simulations. Researchers have carefully simulated the atmospheric chemistry of alien worlds devoid of life thousands of times over a period of more than four years, varying the atmospheric compositions and star types. |
| 'Hot Jupiters' provoke their own host suns to wobble Posted: 11 Sep 2014 10:54 AM PDT Blame the 'hot Jupiters.' These large, gaseous exoplanets can make their suns wobble when they wend their way through their own solar systems to snuggle up against their suns, according to new research. |
| Lurking bright blue star caught: The last piece of a supernova puzzle Posted: 11 Sep 2014 06:47 AM PDT Astronomers have found evidence of a hot binary companion star to a yellow supergiant star, which had become a bright supernova. Its existence had been predicted by the team. This finding provides the last link in a chain of observations that have so far supported the team's theoretical picture for this supernova. |
