The NASA Mars rover launch in 2020

A team of scientists and engineers shared some characteristics and the NASA rover sent to Mars in 2020 should look for signs of past life, collect samples for probable arrival to Earth, and test technology for future human exploration of the Red Planet, along with a new statement from the U.S. space agency.

Large sunspot group

In the Academy of Sciences astro photographers circle he was not previously active, even more warmly now our "Welcome". On 7 July this year, he managed the mosaic of an interesting area to a large sunspot group (AR 1785). He used a Meade Refractor (ED 152 mm with 3x Barlow lens) and as a DMK camera 21AU618.AS. At 3657 mm effective focal length (aperture 24) the frames of the video sequence were exposed to 0.2 ms. 

The Great Wall of China is not can be seen from space

Sun's 2013 Solar Activity Peak Is Weakest in 100 Years

Though the sun is currently in the peak year of its 11-year solar weather cycle, our closest star has been rather quiet over all, scientists say.

This year's solar maximum is shaping up to be the weakest in 100 years and the next one could be even more quiescent, scientists said Thursday (July 11).

SUNNY TAIL: 3D quatrefoil

In the solar system is the tail of the solar wind particles, resembling the tail of a comet. To verify the existence of this tail, and determine its structure, scientists were able, after analyzing data collected over three years, the spacecraft NASA IBEX.
