Milky Way Ransacks Nearby Dwarf Galaxies
Washington DC (SPX) Oct 17, 2014
Astronomers using the National Science Foundation's Green Bank Telescope (GBT) in West Virginia, along with data from other large radio telescopes, have discovered that our nearest galactic neighbors, the dwarf spheroidal galaxies, are devoid of star-forming gas, and that our Milky Way Galaxy is to blame. These new radio observations, which are the highest sensitivity of their kind ever undertaken, reveal that within a well-defined boundary around our Galaxy, dwarf galaxies are completely devoid o ... read more

Tempur-Pedic Mattress Comparison & Memory Foam Mattress Review

Microbes in deep-sea rocks eat methane, lots of it Most methane is buried deep in the ground. Some of it, however, bubbles up to escape, and that's good news for methane-loving microbes living in rocks that gather along the ocean's floor near methane sea vents, munching away on the colorless, odorless assembly of hydrocarbons. ... more		Rare 'baby rattle' molecules reveal new quantum properties of H2O and H2 The experiments were carried out on endofullerenes, molecules of C60 into which smaller molecules of Hydrogen (H2) had been inserted.
