You’re looking at a 55’ x 55’ Deep Sky Survey image of the Rosette Nebula, a large, spherical, star-forming region located about 5,200 light-years away. In a recent study led by Koraljka Mužić (University of Lisbon, Portugal), a team of scientists has used the Gemini South telescope in Chile to obtain near-infrared images from deep in the heart of the nebula.

Zooming in on a region of less than 25 square light-years (the central cyan-outlined region in the photos above and to the right), Mužić and collaborators have imaged the center of NGC 2244, a young, high-density stellar cluster forming massive stars. In their study, the authors seek to understand how low-mass stars and brown dwarfs form and evolve among their high-mass siblings in these extreme environments.
