Key Takeaways
Messier 82, also known as the Cigar Galaxy, is located 12 million light-years away in the constellation Ursa Major and has a unique bar-like shape.
New imaging data from the High Resolution Channel of Hubble's Advanced Camera for Surveys offers insights into the galaxy that were not previously available.
Messier 82 has a very high rate of star formation, producing stars at a rate 10 times greater than the Milky Way, leading to the creation of super star clusters.
The galaxy shines about five times brighter than the Milky Way due to its abundance of stars.
Hubble's latest images reveal active star formation and dark dust clouds that obscure much of the light from the stars, prompting continued research into star formation and its evolution.
The Messier 82 galaxy, also referred to as NGC 3034, is situated a mere 12 million light-years away in the constellation Ursa Major, known as The Great Bear. This galaxy is distinctive for its stretched bar-like shape, giving it a resemblance to a cigar. Thus, it is often called the Cigar Galaxy.
New Imaging Insights
Messier 82 has been observed by renowned space telescopes such as James Webb and Hubble. Nevertheless, the latest image presents data that hasn’t been showcased before. This new data comes from the High Resolution Channel of the Advanced Camera for Surveys (ACS).
The ACS is an instrument on Hubble that captures images across ultraviolet, visible, and infrared wavelengths. It comprises three sub-instruments, with the High Resolution Channel being one of them. Unfortunately, this particular channel was only operational between 2002 and 2007.
Star-Studded Galaxy
Studies of Messier 82 have consistently shown that it is brimming with stars. Researchers have determined that its high rate of star formation is the reason behind the abundance of stars. This rapid formation has led to the creation of super star clusters within the galaxy.
It is believed that Messier 82 generates stars at a rate 10 times greater than that of the Milky Way. Not surprisingly, this galactic neighbor shines about five times brighter than our own Milky Way.
Hubble's Stunning Display
The Hubble Picture of the Week showcases a bluish hue at the center of the galaxy, indicating active star formation. Additionally, the image reveals dark dust clouds that appear black in the center and red around the edges. These clouds obscure much of the light emitted by the stars.
Scientists persist in utilizing Hubble to explore areas like this in an effort to gain deeper insights into star formation and its evolution.
