Astronomers explore the
scale of the universe by first calculating the distance to nearby objects,
using them as reference points (standard candles). The close observation of a
rare type of double star has allowed a team of astronomers presume a much more
accurate value for the distance to LMC: 163,000 light years.

Astronomers, first time directly observed a planet
An international Astronomers
team lead by Sascha Quanz from ETH Zurich in Switzerland examined the gas and
dust disk around the young star HD 100546, which is located at a distance of
only 335 light years in relative closeness to our solar system. The researchers
were surprised when they found evidence of a planet that - surrounded in the
disk of theme around the young star - is still in the development process. This
possible planet would be a gas giant similar to Jupiter in our solar system.

Spaceship Dragon docked to the ISS
Spaceship Dragon, built
by a private company SpaceX, safely reached the International Space Station - even
though a day later than expected.
After the launch of the
ship begin to experience serious problems: three of its four engines
orientation refused to work because of a failure in the fuel system, and the
operators had to spend several hours trying to revive them. It ended well, and
the "Dragon", though late, but made friends with the ISS was
successfully "caught" by the robot arm Canadair and docked to the
station.

A comet will pass very close to Mars
Newly exposed comet
will pass very close to Mars. It is possible and collision.
Comet C/2013 A1 - the
first of astronomers open this year. Its orbit is estimated to take place very
close to Mars in October 2014 a comet fly only 37 000 km from the Red Planet.
This in itself would be a significant astronomical event,

Cold bed in the Sun
Observations with the
infrared Herschel Space Telescope discovered the star Alpha Centauri A strange
"cold bed", exactly the same as that of our sun.
Our star is composed of
six layers: the core, where fusion reactions occur, areas of radioactive
transfer, convective zone, photosphere, chromospheres and corona.

Restoration Curiosity rovers
Last Thursday (February 28) fails, in which the rover
operators were forced to switch from the main system to a back-in and break up
research Curiosity.
On Saturday, the rover out of the "safe mode” and on
Sunday again mobilized antenna with high gain. One of the options for further
work, the operator in question Curiosity,

The Depths of ocean Europe
Found proof that the
ocean in Europe, Jupiter, and a captive under a layer of ice has an exit to the
surface.
The mission of Galileo
(1989-2003) bring a lot of scientist’s important data about Jupiter and its
moons, but the on-board infrared spectrometer probe was not able to identify
all the parts needed to refine the mineral composition of the surface of
Europe. Now, using a spectrometer OSIRIS (Keck Observatory, Hawaii), the
researchers have made an interesting discovery.
