| Einstein's Cosmological Constant Predicts Dark Energy |
| Nov 22, 2005 - Researchers are finding that the mysterious dark energy found to be accelerating the expansion of the Universe is remarkably well predicted by Einstein's cosmological constant. Einstein originally added this constant to balance out the gravitation of the Universe, but threw it out after seeing evidence of the Big Bang. An international team of researchers has performed the Supernova Legacy Survey, and found that it calculates dark energy to be within 10% of Einstein's prediction. (Full Story) |

You're above much of the Earth's atmosphere, and should be able to see a clearer view of the night sky than from the ground. (Full Story) |

| Wispy Terrain on Dione |
| Nov 22, 2005 - In this Cassini image of Saturn's moon Dione, you can see the wispy features that run across its surface. It's also possible to see the craters Dido and Antenor near the moon's terminator at lower left. Cassini took this image on October 9, 2005 from a distance of 1.8 million kilometers (1.1 million miles). (Full Story) |
