When amateur astronomers turn their telescopes toward Hercules, the usual target is Messier 13, one of the brightest, easiest-to-find globular clusters in the northern sky. But a stone’s throw away is another bright companion – M92 – that runs a close second, containing some 330,000 stars orbiting the Milky Way’s core at a distance of 33,000 light years. Visible to the unaided eye under dark sky conditions, M92 was discovered by Johann Elert Bode in 1777. Four years later, Charles Messier spotted it and added the cluster to his famous catalogue. Neither man could have imagined the splendour revealed by the Hubble Space Telescope as seen in this stunning view.

Hubble sees a lonely starburst galaxy
This NASA/ESA Hubble Space Telescope image shows an isolated starburst galaxy named MCG+07-33-027. The galaxy lies some 300 million light-years away from us, and is currently experiencing an extraordinarily high rate of star formation — a starburst. Normal galaxies produce only a couple of new stars per year, but starburst galaxies can produce a hundred times more than that!
