Canes Venatici (/ ˈ k eɪ n iː z v ɪ ˈ n æ t ɪ s aɪ / KAY-neez vin-AT-iss-eye) is one of the 88 constellations designated by the International Astronomical Union (IAU). It is a small northern constellation that was created by Johannes Hevelius in the 17th century.
NGC 2359 (also known as Thor's Helmet) is an emission nebula [3] in the constellation Canis Major.The nebula is approximately 3,670 parsecs (11.96 thousand light years) away and 30 light-years in size.
The nebula was formed about 70,000 years ago by the star EZ Canis Majoris throwing off its outer hydrogen layers, revealing inner layers of heavier elements. [2] Fast stellar winds, blowing at 1,700 km/s (3.8 million mph) from this star, create the bubble-shaped nebula as they sweep up slower moving material from an earlier phase of the star's evolution.

The Heart Nebula (also known as the Running Dog Nebula, Sharpless 2-190) is an emission nebula, 7,500 light-years (2,300 pc) away from Earth and located in the Perseus Arm of the Galaxy in the constellation Cassiopeia. It was discovered by William Herschel on 3 November 1787. [1] It displays glowing ionized hydrogen gas and darker dust lanes. [2]
Located around 30' northeast of NGC 2360, [91] NGC 2359 (Thor's Helmet or the Duck Nebula) is a relatively bright emission nebula in Canis Major, with an approximate magnitude of 10, which is 10,000 light-years from Earth. The nebula is shaped by HD 56925, an unstable Wolf–Rayet star embedded within it. [92]
