There are so many incredible astronomical photographs released every year that picking ten as the most beautiful is a substantial task. But it becomes easier when you consider the science behind the image as well. Does this image tell us more than that one? Was the scientific result drawn from an image surprising, or did it firm up a previously considered hypothesis?

The Japan Aerospace Exploration Agency (JAXA) and NHK (Japan Broadcasting Corporation) have successfully performed the world's first high-definition image taking of an Earth-rise* by the lunar explorer "KAGUYA" (SELENE,) which was injected into a lunar orbit at an altitude of about 100 km on October 18, 2007 (Japan Standard Time.

Parallel universes really do exist, according to a mathematical discovery by Oxford scientists described by one expert as "one of the most important developments in the history of science".
The parallel universe theory, first proposed in 1950 by the US physicist Hugh Everett, helps explain mysteries of quantum mechanics that have baffled scientists for decades, it is claimed.
In Everett's "many worlds" universe, every time a new physical possibility is explored, the universe splits. Given a number of possible alternative outcomes, each one is played out - in its own universe.
A motorist who has a near miss, for instance, might feel relieved at his lucky escape. But in a parallel universe, another version of the same driver will have been killed. Yet another universe will see the motorist recover after treatment in hospital. The number of alternative scenarios is endless.
It is a bizarre idea which has been dismissed as fanciful by many experts. But the new research from Oxford shows that it offers a mathematical answer to quantum conundrums that cannot be dismissed lightly - and suggests that Dr Everett, who was a Phd student at Princeton University when he came up with the theory, was on the right track."
Combining LandSat 7 imagery with Shuttle Radar Topography Mission (SRTM) Data, World Wind can display a dramatic view of the Earth at eye level. Users will literally be able to fly across the world in any direction.
Goddard Space Flight Center (GSFC) has produced a set of visually intense animations that demonstrate a variety of subjects such as hurricane dynamics and seasonal changes across the globe.
World Wind can take these animations and play them directly on the world. Anyone can immediately grasp where the event is taking place as World Wind rotates automatically into view.
Moderate Resolution Imaging Spectroradiometer or MODIS produces a set of time relevant data that's updated every day. MODIS catalogs fires, floods, dust, smoke, storms and even volcanic activity.
GLOBE sample - maximum temperature demonstrated GLOBE
World Wind is capable of browsing through and displaying GLOBE data based on any time the user wants. For example, a user can download today's (or any previous day's) temperature across the world.
In Google Earth, a Service for Scanning the Heavens - New York Times

Google is unveiling within Google Earth today a new service called Sky that will allow users to view the skies as seen from Earth. Like Google Earth, Sky will let users fly around and zoom in, exposing increasingly detailed imagery of some 100 million stars and 200 million galaxies.
