 M80, Backtracking partway to Antares from the head of Scorpius, try hunting for this 7th-magnitude globular cluster. It's very different from M4 and is tiny and concentrated, almost starlike in binoculars. It is a challenge just to identify. An 8.4-magnitude star lies just off M80's northeastern edge, then look for signs of its nonstellar fuzziness. On May 21, 1860, a supernova occurred in M80, completely changing the appearance of this globular cluster for some days. |
