Another globular cluster from earlier in the year, this time m13 - the hercules globular cluster. At 145 light years across, the stars are more than a hundred times denser than in our part of space which would make for an incredible night sky! In 1974 the Arecibo radio telescope beamed a welcome message to m13 containing information about the human race including our dna. Given the distance it should arrive in about 22,000 years.
