The Pale Blue Dot

The Pale Blue Dot is a photograph of Earth taken in 1990 by the Voyager 1 spacecraft from a distance of about 6 billion kilometers from Earth. In the photograph, Earth is shown as a tiny dot against the vastness of space. The Voyager 1 spacecraft, which had completed its primary mission and was leaving the Solar System, was commanded by NASA to turn its camera around and to take a photograph of Earth across a great expanse of space, at the request of Carl Sagan. He later used the image as the main title of his 1994 book, Pale Blue Dot: A Vision of the Human Future in Space.

Solar flare

A solar eruption that blasted an estimated billion tonnes of material into space has been captured by Nasa's Solar Dynamics Observatory.

The eruption, known as a coronal mass ejection (CME), was accompanied by a solar flare that emerged from a sunspot on Tuesday. The solar flare is expected to reach Earth later today. It could possibly affect power grids and GPS satellites.

Postcard from Mars


Today NASA Spirit Rover transmitted sharpest picture ever taken of surface of Mars. NASA said the "postcard" had three to four times the resolution of any other pictures but I don't know how they could miss the first sign of life on the top right corner of the picture!
