Manatee Nebula

==Overview==
Manatee Nebula (also known as W50 or SNR G039.7-02.0) is a supernova remnant nebula situated in the equatorial constellation of Aquila and about 16.01 kilolight-years from Earth. It has a large apparent size of 0°15'01.98" as seen from the Solar System's vantage point, meaning it can span about four full Moons. Due to its looks, the nebulae is named after an endangered aquatic mammal called the Florida manatee. In its center lies an X-ray binary system called SS 433. Approximately 20,000 years ago, a massive star experienced a supernova explosion, which sent its outer gases shooting outward into a rapidly growing bubble. The growing gases of the W50 bubble were eventually penetrated by the SS 433's jets, which eventually caused bulges to appear on each side. Along with their precession, the jets also create striking corkscrew patterns on the expanding bulges. The surviving, gravitationally squashed remnant of that massive star, which is probably a black hole, sucks up material from another nearby partner star. The Westerhout Catalog, published in 1958 by Dutch astronomer Gart Westerhout, designated the Manatee Nebula as Westerhout 50, or W50 for short, for the 50th radio source, offering it a less symbolic name.https://www.nrao.edu/pr/2013/w50/
