The images were pieced together from thousands of images taken over many months by the satellite's remote-sensing device Modis, of every square kilometre of the Earth's surface.

The Earth in True Colors
These spectacular images of the Earth are the most true-colour images of the entire world released to date, according to Nasa scientists.
The images were pieced together from thousands of images taken over many months by the satellite's remote-sensing device Modis, of every square kilometre of the Earth's surface.

Oh, oh, I'm an Alien
Scientists say that a meteorite that crashed into Earth 40 years ago contains millions of different carbon-containing, or organic, molecules.
The Murchison meteorite landed in a town of that name in Australia in 1969. It has been examined before by scientists looking for specific compounds but this is the first non-targeted analysis and has confirmed a huge variety of carbon-based chemicals.
It is thought the Murchison meteorite could even be older than the Sun, originated more than 4.65 billion years ago. The researchers say it probably passed through primordial clouds in the early Solar System, picking up organic chemicals.
The chances of such a meteorite crashing into the Earth billions of years ago and thus creating life in all its diversity are pretty high. Well, doesn't this make us aliens... What do you think?

If Earth had Rings
An amazing video with amazing images of what the earth would look like from different cities and latitudes accross the world if it had rings like Saturn.
