Europa. It's covered in ice and is one of the smoothest objects in the Solar System. The small number of craters shows that the surface is young, possibly only a 100 million years old. (That's young geologically.) In this picture you can see that there are also cracks and streaks. The cracking is caused by tidal heating, but we don't know exactly what the staining is. ©Mona Evans,"Jupiter's Galilean Moons" www.bellaonline.c...

Astrobiology encompasses the search for habitable environments in our Solar System and habitable planets outside our Solar System, the search for evidence of prebiotic chemistry, laboratory and field research into the origins and early evolution of life on Earth, and studies of the potential for life to adapt to challenges on Earth and in outer space. Astrobiology addresses the question of whether life exists beyond Earth, and how humans can detect it if it does.

This "Water bear" (Tardigrade) is an animal which is built only on a few hundred cells. It lives in moss and "awakes" when the moss gets wet. It feeds on moss by sucking the cells off. If the moss fells dry, Water Bears encapsule themselfes, if necessary for years to wait for the next rain. By FEI Company

Orion's Dreamy Stars - NASA Spitzer Space Telescope

In 2004, astronomers discovered a star composed entirely of diamond, measuring 4,000 km across and 10 billion trillion trillion carats. 50 light years from Earth, the diamond star is classified as a crystallized white dwarf, the hot core that remains after a star burns out. Only recently have scientists been able to study the contents of the white dwarf, and they’ve confirmed that the crystallized carbon interior of the star is, in fact, the galaxy’s largest diamond.
