Vulpecula /vʌlˈpɛkjʊlə/ is a faint constellation in the northern sky. Its name is Latin for little fox, although it is known simply as the fox. It was identified in the century, and is located in the middle of the Summer Triangle. There are no stars brighter than 4th magnitude in this constellation, the brightest star in Vulpecula is Alpha Vulpeculae, a magnitude 4. 44m red giant at a distance of 297 light-years. The star is a binary that can be split using binoculars. The star also carries the traditional name Anser, which refers to the goose the little fox holds in its jaws,23 Vulpeculae is the second brightest star in the constellation. In 1967, the first pulsar, PSR B1919+21, was discovered in Vulpecula by Jocelyn Bell, supervised by Antony Hewish, while they were searching for scintillation of radio signals of quasars, they observed pulses which repeated with a period of 1.3373 seconds. Terrestrial origin of the signal was ruled out because the time it took the object to reappear was a day instead of a solar day. This anomaly was finally identified as the signal of a rotating neutron star. Fifteen years after the first pulsar was discovered, the first millisecond pulsar, PSR B1937+21, was discovered in Vulpecula. Vulpecula is also home to HD189733 b, one of the closest extrasolar planet currently being studied by the Spitzer Space Telescope, on 12 July 2007 the Financial Times reported that the chemical signature of water vapour was detected in the atmosphere of this planet. The Dumbbell Nebula, is a large, bright planetary nebula which was discovered by the French astronomer Charles Messier in 1764 as the very first object of its kind. It can be seen with binoculars in a dark sky location. A telescope reveals its double-lobed shape, similar to that of an hourglass, brocchis Cluster is an asterism formerly thought to be an open cluster. It is also called the Coathanger because of its distinctive star pattern when viewed with binoculars or a low power telescope, NGC7052 is an edge-on spiral galaxy in Vulpecula at a distance of 214 million light-years from Earth. It has a dusty disk with a diameter of 3700 light-years. Astronomers surmise that the disk is the remnant of a galaxy that merged with NGC7052. Jets can be seen emanating from the galaxy, and it has very strong radio emissions and this means that it is also classified as a radio galaxy
