Cassiopeia -- New Photo Reveals ‘Ghostly’ Green Nebula in Deep Space An amazing new photo from a telescope in Chile has captured the most detailed view yet of a green glowing blob 3,300 light-years away from Earth.

A Cosmic Exclamation Point VV 340 contains a pair of interacting galaxies that are destined to merge. The Chandra data shows that the northern galaxy contains an obscured and rapidly growing supermassive black hole. Data from other observatories shows that the two galaxies are evolving at different rates. VV 340, also known as Arp 302, provides a textbook example of colliding galaxies seen in the early stages of their interaction.
Einstein’s General Theory of Relativity has recently been challenged under the most extreme conditions so far, and emerged victorious. A pulsar and a white-dwarf were recently discovered orbiting each other, providing a unique arena to test gravitational theories. Though some of the scientists expected the theory to fail, the findings were consistent with what Einstein had laid out in 1915.

Galaxy Cluster Abell 1689 Abell 1689 is one of the most massive galaxy clusters known. The gravity of its trillion stars, plus dark matter, acts like a 2-million-light-year-wide "lens" in space. The gravitational lens bends and magnifies the light of galaxies far behind it.
