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.

As amateur astronomers can help lunar mission LADEE
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.
Hubble sees galaxies colliding in outer space
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.
NASA probes TWINS: five years of observations of ring current Earth
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.

Our galaxy has greater than before its diameter is ten times
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.
Search for life on Mars spacecraft sterilization
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,
Scientists have discovered why people like the smell of rain
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.
