Earth Viewing Online from International Space Station

The High Definition Earth Viewing (HDEV) experiment places four commercially available HD cameras on the exterior of the space station and uses them to stream live video of Earth for viewing online. The High Definition Earth Viewing (HDEV) experiment aboard the ISS was activated April 30, 2014. The cameras are enclosed in a temperature specific housing and are exposed to the harsh radiation of space. Analysis of the effect of space on the video quality, over the time HDEV is operational, may help engineers decide which cameras are the best types to use on future missions.

Birth of the Black Holes

Black holes are celestial objects which are so dense, that not even light can escape they intense gravitational pull. Their gravity is not sufficient to overpower the atomic and nuclear forces of their interiors, which resist compression. But in more massive objects, gravity ultimately wins. This phenomenon occurs when a dying stars runs out of fuel and collapses under the weight of their own gravity. According to scientists, there might be three types of black holes : stellar, supermassive, and miniature black holes – depending on their mass. Astronomers can measure the mass of black holes by studying the material that orbits around them.

Video map of the movement of galaxies near Universe

The international team of researchers created the video map of the movement of galaxies neighbor the Universe in more detail, than before. Video map is provides dynamic three-dimensional idea of the Universe with help of turn, scrolling and scaling. The space project Streams planned visible and dark matter density round our galaxy Milky Way at distance of 300 million light years. Our galaxy Milky Way lies in a congestion of 100000 galaxies. The movement of tectonic plates shows properties of an interior of Earth. And the movement of galaxies shows information on the main components of the Universe, which is dark energy and dark matter. Dark energy is the mysterious force, which causes expansion of the Universe.

Tour of the Moon

The Moon is the only natural satellite of the Earth and the fifth largest satellite in the Solar System. It is the largest natural satellite of a planet in the Solar System relative to the size of its primary, having a quarter the diameter of Earth but only 1⁄81 its mass. The Moon is the second densest satellite after Io, a satellite of Jupiter. It is in synchronous rotation with Earth, always showing the same face with its near side marked by dark volcanic maria that fill between the bright ancient crustal highlands and the prominent impact craters. The Moon is the brightest object in the sky after the Sun, although its surface is actually very dark, with a reflectance similar to that of coal.
