This striking image of the M82 Cigar Galaxy showcases the exceptional capabilities of the Lulin One-meter Telescope (LOT) located at the Lulin Observatory in Taiwan. M82, also known as the Cigar Galaxy, is a captivating starburst galaxy located approximately 12 million light-years away in the constellation Ursa Major.

In this vivid capture, the elongated shape of M82, reminiscent of a cigar, is easily discernible, giving the galaxy its famous moniker. The vibrant colors reveal the galaxy's active star-forming regions, where intense stellar winds and supernova explosions have sculpted the intricate filaments of glowing gas and dust visible throughout the image. The reddish hue (bipolar outflow) emanating from the central region of M82 is caused by ionized hydrogen gas, driven by the stellar winds and supernova explosions occurring within the galaxy.

The high-resolution image provided by the Lulin's 1-meter telescope has allowed astronomers to study the detailed structure of M82, offering invaluable insights into the processes driving this remarkable starburst galaxy. The Cigar Galaxy's proximity to our own Milky Way makes it an ideal cosmic laboratory for researchers to investigate the complex interplay between star formation, galactic winds, and the evolution of galaxies.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
