Astronomers have
calculated that the birth of planets around young stars can occur even at a
later stage than previously considered. In the study of the properties of star
TW Hydra found strong evidence. This star is at a distance of 176 light-years
from Earth, refers to the spectral type K8 and attracts the surrounding gas and
dust astronomers drive. A few years ago, close to the TW Hydra was discovered
planet, which weighs slightly larger than Jupiter.

Noting the weather patterns of a brown dwarf
Hubble space telescopes
and NASA's Spitzer investigated the stormy atmosphere of a brown dwarf called
2MASSJ22282889-431 026, creating the "climate map" far closer to this
kind of cold orbs similar to stars. The forecast shows clouds planet-sized
wind-driven involving these strange worlds.
Brown dwarfs are formed
from the condensation of gas, as do the stars,but lack the necessary amount of
mass to fuse atoms and energy.
Venus, ionosphere swells in its night side like comet
The ESA’s some unique
observations of Venus through a period of low solar wind pressure, discovering
that the planet's ionosphere swells in its night side, like the tail of a
Comet.
The ionosphere is a weekly
electrically charged gaseous region far above the main body of the planet's
Atmosphere. The form and are partially controlled by the internal magnetic
field of the planet.

Taimyr bacteria were able to live on Mars
US-Russian group of
Scientists found the frozen bacteria of Taimyr bacteria, which can develop in
the temperature, pressure and oxygen attentiveness matching to the Martian
Atmosphere.
The paper was published
in the journal Proceedings of the National Academy of Sciences, and a summary
of its results in Spiegel Online.

A structure of stars
The complicated
filaments of dust and gas that make up this astrophysical nursery home to more
than 600 stars in formation. This province was first observed by the Herschel
space observatory of ESA.
The province colored
blue nebula, known as W40, or Sharpless 2-64, is located 1,000 light-years from
Earth in the direction of the constellation Aquila,

As feline parasite infects humans
Czech biologist Jaroslav
Flegrei is known for his statement that the common freeloader known as
Toxoplasma (Toxoplasma gondii) is able to "manage" the human brain.
Toxoplasma is which
usually affects cats, known with scientists through their "smart tactics."
Coming from a cat in a rodent parasite makes him fearless, directing poor
straight into the jaws of a cat. The freeloader multiplies in the cat, then the
feces is disqualified, thus again can get to the rodent.
Flegrei discovered that
people infected with the parasite, it is peculiar behavior like rats: slow
reaction, lethargy and reduced fear. But until recently, scientists did not
know the mechanism of the nervous system.
Life in thunderclouds
The storm clouds in the
Earth's atmosphere found wealth microbial life.
Scientists investigated
the chemical composition of hailstones. As a result, found several types of
bacteria that are usually found in plants, and organic compounds that are
commonly found in soil. Were bacteria, which produce pink pigment, which
protects them from UV rays?
