The constellation Ursa Major is the site of a spiral galaxy called M109. It is classified as a barred spiral. The elongated shape of its central core can be seen even in small instruments. This galaxy is located about 55 million light-years from Earth and is believed to be receding from us at a whopping 1142 km/sec. It was the site of a supernova in 1956 that reached a magnitude of 12.8. M109 is easily visible in small instruments where its bright central region appears pear-shaped. Larger instruments will reveal more detail.
