New observations of the star cluster Messier 54, shown above, reveal that it is just as strangely deficient in lithium as our own galaxy, deepening a mystery about the element’s big bang origins. (Credit: ESO)

This graph shows the distribution of about 20,000 luminous Sloan Digital Sky Survey quasars in the two-dimensional space of broad line width versus FeII strength, color-coded by the strength of the narrow [OIII] line emission. The strong horizontal trend is the main sequence of quasars driven by the efficiency of the black hole accretion, while the vertical spread of broad line width is largely due to our viewing angle to the inner region of the quasar.

To see something new, inventor, Raffi Budakian, had to get small — really small. The instrument he uses is as long as a human hair is wide and has the circumference of a virus.(Credit: The Budakian Group)

“Using a new operating principle called the “hot-electron photothermoelectric effect,” the research team created a device that is “as sensitive as any existing room temperature detector in the terahertz range and more than a million times faster,” says Michael Fuhrer, professor of physics at UMD and Monash University. The above image is a Graphene photothermoelectric detector device fabrication and principle of operation.” (Credit: Nature.com)

The Big Bang theory suggests that at some moment all matter in the universe was contained in a single point, which is considered the beginning of the universe.via timesofindia.com
Simulated view of a black hole (center) in front of the Large Magellanic Cloud. Note the gravitational lensing effect, which produces two enlarged but highly distorted views of the Cloud. Across the top, the Milky Way disk appears distorted into an arc.
