| Hubble to begin search beyond Pluto for a New Horizons mission target Posted: 16 Jun 2014 10:03 AM PDT NASA's Hubble Space Telescope will be used to search for a suitable Kuiper Belt object that NASA's New Horizons space probe could visit. It would be our first and perhaps last look at such a remote relic from the distant past. The search is very challenging even for Hubble's sharp vision. It has to find something the size of Manhattan Island, as black as charcoal, and embedded against a snowstorm of background stars. |
| Giant telescopes pair up to image near-Earth asteroid Posted: 16 Jun 2014 07:07 AM PDT NASA scientists using Earth-based radar have produced sharp views of a recently discovered asteroid as it slid silently past our planet. Captured on June 8, 2014, the new views of the object designated "2014 HQ124" are some of the most detailed radar images of a near-Earth asteroid ever obtained. |
| Herschel sees budding stars and a giant, strange ring Posted: 16 Jun 2014 06:57 AM PDT The Herschel Space Observatory has uncovered a weird ring of dusty material while obtaining one of the sharpest scans to date of a huge cloud of gas and dust, called NGC 7538. The observations have revealed numerous clumps of material, a baker's dozen of which may evolve into the most powerful kinds of stars in the universe. Herschel is a European Space Agency mission with important NASA contributions. |
| High-mass stars are rarely solitary: Binary stars are more common than thought Posted: 16 Jun 2014 05:21 AM PDT High-mass stars are rarely solitary, according to new research. For several years, astronomers observed 800 celestial objects that are up to one hundred times heavier than our sun. More than 90 per cent have turned out to be multiple systems. These data support the theory that heavy stars are already formed as twins. |
