NASA - Messier 82 Galaxy (NIRCam Image) James Webb Telescope
Messier 82, also known as the Cigar Galaxy, is a stunning spiral galaxy located approximately 12 million light-years away in the constellation Ursa Major. When observed with the Near Infrared Camera (NIRCam) aboard the James Webb Space Telescope (JWST), its beauty and complexity are revealed in exquisite detail.
The NIRCam image of Messier 82 showcases the galaxy's intricate structure and dynamic features in the near-infrared spectrum. Unlike visible light, which can be obscured by dust and gas, near-infrared light can penetrate these obstacles, allowing astronomers to peer deep into the heart of galaxies like M82.
In the image, we see the distinctive elongated shape that gives Messier 82 its nickname, the Cigar Galaxy. The galaxy's central region appears bright and luminous, with intense star formation activity evident in the form of bright knots and filaments of gas and dust. These regions are known as starburst regions, where massive stars are born at a rapid rate, illuminating their surroundings with their intense radiation.
Streaming out from the central region are dark lanes of dust, which trace the spiral arms of the galaxy. These lanes are regions where new stars are forming, hidden from view in visible light but revealed in the near-infrared. Surrounding the central core, we see the extended spiral arms of the galaxy, dotted with countless stars and star clusters.
The NIRCam image also reveals the presence of vast clouds of molecular gas, which serve as the raw material for star formation. These clouds appear as dark, filamentary structures crisscrossing the galaxy, providing the fuel necessary for the ongoing process of stellar birth and evolution.
The NIRCam image of Messier 82 taken by the James Webb Space Telescope offers a mesmerising glimpse into the dynamic and turbulent world of star formation within this remarkable galaxy, highlighting the power of infrared astronomy to unveil the hidden secrets of the universe.
