Astronomers have long known that the Universe is expanding, but everything they could see indicated that gravity should be slowing this spread. Instead, it appears that the Universe is accelerating its expansion and that something stronger than gravity --dark energy -- is at work. In Einstein's Telescope Evalyn Gates, a University of Chicago astrophysicist, transports us to the edge of contemporary science to explore the revolutionary tool that unlocks the secrets of these little-understood cosmic constituents. Based on Einstein's theory of general relativity, gravitational lensing, or "Einstein's Telescope," is enabling new discoveries that are taking us toward the next revolution in scientific thinking -- one that may change forever our notions of where the Universe came from and where it is going.$19.95
As you look up into the sky at night you can see many stars.
The Wongutha people of the Eastern Goldfields area of Western Australia tell stories about the stars, explaining how the stars came to be where they are. Some stars are grouped together and have special names.
One of these groups of stars is called the Seven Sisters. The Sisters were beautiful women who used to visit the earth and wander the land. This is the story of why they appear in their position in the night sky.
