HELLO FROM EARTH Update... As of 7 PM California time tonight (12 PM Sydney time on Friday, September 11), it has been two weeks since a radio signal containing 25,880 goodwill text messages—including one by me—was transmitted to the exoplanet Gliese 581d from a giant NASA antenna in Australia. The signal is now 225 billion miles (362 billion kilometers) from Earth.
Recently, the Hello From Earth website updated with this cool display (on the right side of the screenshot below) counting down to the day the signal arrives at Gliese 581d, as well as the signal’s current distance from that planet and certain regions in our solar system. Nice. Though it seems like COSMOS Magazine will be spending a fortune on its webhost if it actually plans to keep this site up for the next 20 years.
