According to New Scientists, astronomers sent a message to another solar system that is a mere 12 light years away, hoping to hear back in about 25 years — Stephen Hawking had suggested not doing so. In the mean time, while we wait to go to Mars, you can always join Asgardia, a virtual country that hopes to be located in space, one day.

This new message – beamed from an antenna in Norway over roughly eight hours over a three-day period in October – is simpler and may be more readily understood, Vakoch says.

It begins with information about counting, arithmetic, geometry, and trigonometry, and includes a description of the radio waves that carry the message, as well as a tutorial on clocks and timekeeping, to see if any potential inhabitants of GJ 273b have an understanding of time similar to our own.
