Location
Messier 93 is located in the constellation Puppis, which is part of the larger Argo Navis constellation. It can be found in the same area of the sky as the bright star Sirius in the constellation Canis Major. A line connecting the stars of Orion’s Belt extended southward leads to Sirius, and then a line extending to the east and a little south for about 10 degrees leads to Messier 93, near the star Zeta Puppis. The best time of year to observe Messier 93 is during the winter.
To locate Messier 93:
- Find the star Sirius in the constellation Canis Major.
- Extend a line from Sirius through the stars Omicron 1 and Omicron 2 Canis Majoris.
- Continue for about 10 degrees to the north to find Messier 93, near the star Zeta Puppis.
Messier 93 can be easily found using star-hopping techniques and is visible with binoculars or small telescopes. Take your time to explore the beautiful constellation of Puppis and marvel at the wonders of Messier 93.
History of Observation
Messier 93, also known as NGC 2447, was first discovered by Charles Messier on March 20, 1781. However, it was independently discovered by Caroline Herschel in 1783, who mistakenly believed that Messier had not yet catalogued it. This significant finding marked the beginning of Caroline Herschel’s illustrious career in astronomy.
