The Planet From Hell – Gliese 581 c

Gliese 581 c wants to kill you. This planet orbits a red dwarf star, many times smaller than our Sun, with a luminosity of only 1.3% of our sun. This means that the planet is far closer to its star than we are to ours. Because of this, it is stuck in a state of tidal locking, meaning that one side of the planet is always facing the star, and one side is always facing away, just like our moon’s relationship with Earth.The tidal locking of the planet alone results in some pretty odd features. Stepping out onto the star-side of the planet would immediately melt your face off, whereas standing on the opposite side of the planet, where there is no sun, would freeze you instantly. However, in between these two extremes is a small belt where life could theoretically exist.

A Message from Earth (AMFE) is a high-powered digital radio signal that was sent on 9 October 2008 towards Gliese 581c, a large terrestrial extrasolar planet orbiting the red dwarf star Gliese 581. The signal is a digital time capsule containing 501 messages that were selected through a competition on the social networking site Bebo. The message was sent using the RT-70 radar telescope of Ukraine’s State Space Agency. The signal will reach the planet Gliese 581c in early 2029. More than half a million people including celebrities and politicians participated in the AMFE project, which was the world’s first digital time capsule where the content was selected by the public.
