The primary survey of stars and the finding of other 'Earths', amazing closer

The primary survey of stars close to the Sun with Earth-like planets are faster to creature a actuality thanks to the spectrometer calibration technique, a technology used to calculate the speed of a star and make measurements with precision and accuracy "unprecedented." This has been noted scientists of the Max Planck, the European Southern Observatory, who have tried this technique to trace the orbit of an exoplanet discovered and which revolve around the star HD75289 and the results published in Nature.

The ESA is evidence that an ocean covered element of Mars

The European Space Agency (ESA) declared today that its Mars Express has provided verification that an ocean enclosed element of the outside of Mars, something that was supposed but remains controversial. The study was based on data provided for over two years by the MARSIS radar, which was deployed on Mars in 2005, and has allowed the experts find that the plains of the northern hemisphere are covered low density material.

Delayed the start of MSG-3 to July 5, 2012

Arianespace announce the start of MSG-3 satellite from Europe's Spaceport in Kourou, originally programmed for June 19 has been delayed until July 5 at night. This delay was caused by additional checks perform on the EchoStar 17 telecommunications satellite to be launched along with MSG-3 aboard an Ariane5 ECA.MSG-3 has successfully passed all pre-launch tests and is ready to begin the process of loading fuel in their tanks.

how to observe the planets of our solar system

The planets of our solar system are on tomes some of the most rewarding and simplest sky watching targets to spot, if you know when and where to look. Here's a look at how to observe the planets of the solar system in 2011. Some have worlds of their own.

Astronomer’s measure distances in the sky in terms of degrees. For reference, your clenched fist held at arm's length covers about 10 degrees of the night sky.

NASA arranged to watch the transit of Venus until 2117

NASA and other EU institutions are arranged to watch the transit of Venus between 5 and 6 June, with dozens of activities to capture the best images from this moment not ensue again until 2117. The transit occurs when Venus passes directly between Earth and the Sun, which will see the planet as a tiny dot gliding slowly across the sun king, a phenomenon that was seen by astronomers as Galileo Galilei. Scientists from the sixteenth and seventeenth observed transits of Mercury and Venus, the two planets "inside", to measure the distance from Earth to the Sun in an effort to estimate the size of our solar system.

The exoplanet "closest" to the Earth

The Kepler space mission has exposed the exoplanet, closet to the Earthlike identified so far. Dub Kepler 10b, the planet is unstable (solid) smaller than those found, since the diameter is the same to just 1.4 times the Earth, while its mass is 4.6 times that of Earth.

In attendance can be no illusions, however, about the possibility of life existing in it, because although Kepler 10b orbits a star (Kepler 10) very similar to our Sun, its distance to it is twenty times less than separating the sun Mercury.

Searching from space in the bowels of the Earth

The ESA astronaut Andre Kuipers of creature approved out an research on the ISS that will shed light on conditions in the depths of our planet. In orbit about 400 km height, Geoflow help us understand how the Earth works inside. Extend to a depth of almost 3000 km; the layer is composed of semi-solid materials graceful slowly under the thin outer shell. For study, it is considered that the mantle is divided into several layers of different viscosity as a result of increased pressure and temperature with depth.
