| Astronomers take sharpest photos ever of the night sky Posted: 21 Aug 2013 12:21 PM PDT Thanks to new technology, astronomers can now view objects in the sky at unprecedented sharpness in visible light. Using a telescope mirror that vibrates a thousand times each second to counteract atmospheric flickering, the team has achieved image resolution capabilities that could see a baseball diamond on the moon. |
| A brighter method for measuring the surface gravity of distant stars Posted: 21 Aug 2013 10:23 AM PDT Astronomers have found a clever new way to slice and dice the flickering light from a distant star in a way that reveals its surface gravity, one of the key properties that astronomers use to calculate a star's physical properties and assess its evolutionary state. |
| 'Zombie vortices' may be key step in star formation Posted: 20 Aug 2013 03:58 PM PDT Scientists have proposed a new model that elucidates a key step in star formation. They point to "zombie vortices" as a destabilizing force needed to help protostars accumulate the mass needed to grow into stars. |
