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. More info: Photo credit: Antoniadis, et…

The Horsehead Nebula 1500 light years away, it is a dark cloud that is visible only because of the lighter nebula behind it.

A Spooky Nebula SH2-136 is a an illuminated dark nebula, about 1200 light-years away, towards the constellation Cepheus.

♥ Great picture of the moon. BUT the website takes you to a fashion line url! Its pinned for the great moon pic!

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.
