Extraterrestrial life in the atmosphere?



British scientists claim to have found alien life in the atmosphere.

Sheffield University researchers say they have found alien life forms in the atmosphere of our planet after analyzing the data obtained by a balloon sent into the stratosphere.

Milton Wainwright, Department of Molecular Biology and Biotechnology and director of the work, is convinced that the microorganisms found in the stratosphere are not of our planet. The discovery was made at the peak of the Perseids, at an altitude of 16.7 miles.

"Most people will argue that these biological particles must, of necessity, have moved into the stratosphere from Earth, but it is known that the particle size of which we have found can not rise from the ground to heights, for example, of 27 km
(16.7 miles). The only exception might be caused by a violent volcanic eruption (to push up those particles), but none of that has happened during the three years that we have been collecting samples. "

"In the absence of a mechanism to explain how these particles can be transported from here to the stratosphere, the researcher only thing we can do is conclude that these biological entities originated in space. Therefore, our findings are that life is continually reaching Earth from space, that life is not restricted only to our planet and it is virtually certain that it did not originate here. "

The extraordinary results of this research are published in the 
Journal of Cosmology.

Robotics Workstation in the International Space Station’s Cupola


At the robotics workstation in the International Space Station's Cupola, NASA astronaut Karen Nyberg, Expedition 36 flight engineer, participates in onboard training activity in preparation for the grapple and berthing of the Japanese "Kounotori" H2 Transfer Vehicle-4 (HTV-4) set for August 9, 2013. 

Nyberg and NASA astronaut Chris Cassidy will use Canadarm2, the station's Canadian Space Agency-provided robotic arm, to reach out and capture the vehicle for its installation on the Earth-facing port of the Harmony node.

What are the parts of the Soyuz Rocket? What are the stages into orbit? What is the launch sequence? Watch and find out. This video has been produced from an actual lesson delivered to the ESA astronaut class of 2009 (also known as the #Shenanigans09) during their ESA Basic Training in 2009-2010.
A very young star, RNO 91, is being born in the guts of the dark cloud LDN 43, 520 light-years from Earth in the constellation of Ophiuchus. The newborn star is hidden in this image, revealed only by light reflected onto the plumes of the dark cloud. A dusty, icy disc surrounding it may host planet embryos.
This image is based on data gathered by the NASA/ESA Hubble Space Telescope. A version of this image was entered into the
CAVES staff under a ray of light coming from the ceiling of a cave, which appears very infrequently throughout the year.
The ESA CAVES team is preparing for CAVES 2013 by doing a 'dry run' at the training site. Procedures, tasks, equipment and locations are checked in preparation for the real thing: sending six astronauts underground in September.
CAVES, an abbreviation of Cooperative Adventure for Valuing and Exercising human behaviour and performance Skills, prepares astronauts to work safely and effectively and solve problems as a multicultural team while exploring uncharted areas using space procedures.

The Envisat satellite found that the dormant Mount Longonot in Kenya rose by 9 cm from 2004 to 2006. Tectonic activity such as the movement of magma underground may have caused this deformation of the surface above.
