Polygons in this image taken by Hirise spacecraft orbiting Mars, are of great interest because they often indicate the presence of shallow ice or of desiccation such as in a mud flat. However, nature sometimes seems too clever for us. Image © NASA/JPL/University of Arizona
Imagine to place New York City on another planet in our solar system. Life of course would cease to exist at least as we know it. You will realize once more that our beautiful blue planet is very rare. The following illustrations were made with the help of Marilyn Vogel.
Photographer Phillip Calais who toke this impressive solar eclipse photo, said: It was just eight minutes after sunrise, last week, and already there were four things in front of the Sun. The largest and most notable was Earth’s Moon, obscuring a big chunk of the Sun’s lower limb as it moved across the solar disk, as viewed from Fremantle, Australia. Image © Phillip Calais.

A record-setting blast of gamma rays from a dying star in a distant galaxy has wowed astronomers around the world. The eruption, which is classified as a gamma-ray burst, or GRB, and designated GRB 130427A, produced the highest-energy light ever detected from such an event.

NASA’s Cassini spacecraft has provided scientists the first close-up of the spinning vortex of Saturn‘s north polar storm. The giant hurricane resembles a deep red rose of giant proportions surrounded by green foliage, in this false-color image. Image © NASA/JPL-Caltech/SSI
A composite of 25 separate images spanning the period of April 16, 2012, to April 15, 2013. It reveals the zones on the Sun where active regions are most common during this part of the solar cycle. Have a look at the video… Image © NASA/SDO/AIA/S. Wiessinger
Astronomers using ESO’s Very Large Telescope, along with radio telescopes around the world, they find and study a bizarre stellar pair consisting of the most massive neutron star, orbited by a white dwarf star. This strange new binary allows tests of Einstein’s theory of gravity — general relativity — in ways that were not possible up to now.
