The Cigar Galaxy, also known as Messier 82 or NGC 3034, is a fascinating galaxy located in the constellation Ursa Major. It is known for its unique cigar-shaped appearance and the intense star formation taking place within it. In this blog, we'll explore the history, characteristics, and fascinating features of the Cigar Galaxy.
History
The Cigar Galaxy was first discovered in 1774 by French astronomer Nicolas-Louis de Lacaille. However, it wasn't until 1781 that German astronomer Johann Elert Bode independently rediscovered it and added it to the Messier catalog as Messier 82.
Characteristics
The Cigar Galaxy is a type of galaxy known as a starburst galaxy, which means it is undergoing an intense period of star formation. It is located about 12 million light-years away from Earth and has a diameter of around 37,000 light-years. Its unique cigar-shaped appearance is due to its intense magnetic field and the fact that it is seen edge-on from our perspective.
Features
One of the most fascinating features of the Cigar Galaxy is its bright central region, which is where most of the star formation is taking place. The galaxy is also known for its beautiful spiral arms, which are filled with gas and dust that are being compressed and heated by the intense radiation from young, hot stars.
In addition, the Cigar Galaxy is also a source of intense radio emissions, which are believed to be caused by the interaction between the magnetic field and the particles in the galaxy's interstellar medium.
Conclusion
The Cigar Galaxy is a unique and fascinating object in the night sky. Its cigar-shaped appearance and intense star formation make it a popular target for astronomers and stargazers alike. As we continue to study and learn more about this galaxy, we may unlock even more mysteries of the universe.
