Description
It occupies an area of 268.2 square degrees in the sky, contains 72 stars visible to the naked eye. Observed throughout Russia , the best observation conditions in the summer .
In this constellation in 1967, radio pulsating stars ( pulsars ) were first discovered. Moreover, even more than 40 years after the first discovery, new pulsars continue to be detected in this constellation: in 2011, an article was published on the discovery of PSR J1952 + 2630 .
Points of Interest
The constellation is poor in bright stars, but you can find interesting objects for observation in it.
One such object is the red-blue planetary dumbbell nebula (M27).
Asterism is known in the constellation, easily visible through binoculars - the Hanger cluster (Cr399).
Six stars of the 6th and 7th magnitude form a straight line, and another 4 stars form a hook that completes the shape of the hanger.
In IRAS 19340 + 2016 , stars with protoplanetary disks are formed.
History
New constellation. Introduced by Jan Hevelius in 1690 under the name Vulpecula cum Ansere - Chanterelle with a Goose. In his atlas “ Uranography ” the constellation was depicted as a fox holding a goose in its mouth. Hevelius himself commented on the constellation: “The fox is a cunning, cruel, greedy and voracious animal that resembles an eagle” [1] (The fox is next to the constellation Eagle ). Later, Gus sometimes stood out in a separate constellation, but this practice did not receive recognition, and the name was reduced to "Chanterelle".
On June 20, 1670, in the constellation Lysychka, a new CK Lysychky was discovered by the Cartesian monk, which was then observed for several years by Jan Hevelius, who first depicted it on the map [2] , and then, probably, in “ Uranography ” [3] . A year later, it reached a visible magnitude of 2.6 m , but already in 1672 its brightness decreased almost to the limit of visibility with the naked eye. The remainder of this new was discovered only in 1982 [4] .
