Chorus of black holes radiates X-rays

The NuSTAR mission is identifying which black holes erupt with the highest-energy X-rays, report scientists. The results will ultimately help astronomers understand how the growth patterns of supermassive black holes change over time, a key factor in the development of black holes and the galaxies that host them.

Ripples Through a Dark Sky
more »
Sunlight ripples through a dark sky on this Swedish summer midnight as noctilucent or night shining clouds seem to imitate the river below. In fact, the seasonal clouds often appear at high latitudes in corresponding summer months. Also known as polar mesospheric clouds, they form as water vapor is driven into the cold upper atmosphere. Fine dust supplied by disintegrating meteors or volcanic ash provides sites where water vapor can condense, turning to ice at the cold temperatures in the mesosphere. Poised at the edge of space some 80 kilometers above, these icy clouds really do reflect sunlight toward the ground. They are visible here even though the Sun itself was below the horizon, as seen on July 16 from Sweden's Färnebofjärdens National Park. Tomorrow's picture: sun flap

Scientists find a way of acquiring graphene-like films from salts to boost nanoelectronics
more »
Scientists have found a way to acquire 2-D graphene-like layers of various salts. Because to the unique properties of two-dimensional materials, this opens up great prospects for nanoelectronics. Using computer modeling they have found the exact parameters, under which certain salts undergo graphitization -- rearrangement of atoms in the slab with further decomposition of a crystal into 2-D layers.The received data will soon be used to acquire these layers experimentally.
