The space between the stars, which is called the interstellar medium is not empty. Although the density of matter is very low (about 10,000 particles per cm3), there is a rich variety of atoms and molecules that populate it. The most abundant material, as in the rest of the universe is hydrogen (in three variants: ionized, atomic and molecular) and helium. But there are also molecules of all kinds, to over a hundred have come to find. Since the most abundant and simple, water (H2O), to large, complex organic chains as acetone or benzene.

Mission Lunar Atmosphere and Dust Environment Explorer (LADEE) scheduled for launch into space from Wallops Island on September 5 this year. LADEE will be the first mission, sent from the Wallops Island, which will go beyond low-Earth orbit. As a joint project of the Goddard Space Flight Center and NASA Ames Research Center, LADEE will learn from orbit conditions that exist on the Moon, including its tenuous exosphere.
Space Telescope NASA / European Space Agency "Hubble" recently made this beautiful picture a pair of interacting galaxies known as Arp 142. When two galaxies approach each other so closely that they begin to interact with each other, they both appear spectacular changes. In some cases, two galaxies can come together, and in the other - on the contrary, to be ripped.
Land surrounds the dynamic area, which accept the name of the magnetosphere. This area is controlled by the magnetic and electric forces coming from the sun energy and matter, as well as a variety of waves and processes that differ from those that are commonly found in terrestrial physics. Within this constantly changing magnetic "bubble" is toroidal formation of charged particles, the plane of which coincides with the plane of Earth's equator.

The astronomers, led by John Stoke by the University of Colorado at Boulder (USA), reported that the new observations spectrograph Space Telescope "Hubble" forced them to rethink the size of the halo of spiral galaxies such as our Milky Way. So - and significantly change our estimates of their mass.
This entire glowing disc, which we used to call the Milky Way, represents only the tip of the iceberg, nine-tenths of which are lost in the darkness.
On Mars, there are aliens, and they came to the Earth. Paradoxically, this argument is designed to ease the process of sterilization, which must pass each spacecraft so as not to bring the Red Planet terrestrial microbes.
These limitations have made the search for life on Mars is costly and inefficient,
Many people would like the smell of rain. This is inbuilt in human nature. Some scientists believe that a person has inherited his love for the smell of rain from the ancestors, which was equal to the rainy weather survival.
There are several flavors that are associated with precipitation and are impressed by the man, reports Rosbalt.
NASA engineers have started on rockets Pegasus XL, which took into space telescope IRIS, designed to study the sun, according to U.S. media. The launch was held in the state of California, according to the news.
The project cost $ 182 million mission of IRIS will last two years.
The observations from the telescope is expected to enable new information on solar flares and solar wind. Furthermore, IRIS makes pictures solar surface.

A Chinese space capsule carrying three astronauts returned safely to Earth Tuesday (June 25), wrapping up the longest manned space mission in the nation's history.
The Shenzhou 10 spacecraft touched down at 8:08 p.m. EDT Tuesday (0008 GMT), capping a 15-day mission to China's orbitingTiangong 1 lab module. The spacecraft landed in northern China's Inner Mongolia Autonomous Region, where the local time was 8:08 a.m. on Wednesday.
An Alaska volcano spewing ash and lava for the past six weeks erupted with new intensity early on Tuesday, belching a plume of cinders 5 miles into sky and onto a nearby town and disrupting local flights, officials said.
The eruptions from Pavlof Volcano, on the Alaska Peninsula 590 miles southwest of Anchorage, were its most powerful since its current eruptive phase began with low-level rumblings in mid-May, according to scientists at the federal-state Alaska Volcano Observatory.
