What's the Rosebud Nebula and are there any new images of it?

The object commonly called the Rosebud Nebula is the Rosette Nebula, a vast cloud of glowing gas and dust in the constellation Monoceros, about 5,000 light-years from Earth. Its formal designations include NGC 2237–2239, while the young open star cluster at its center is NGC 2244. The nebula is an enormous star-forming region, stretching roughly 100–130 light-years across, where ultraviolet radiation and powerful stellar winds from hot, young stars have carved out the large hollow at its center. The familiar rose-like appearance comes from the surrounding hydrogen gas, dust lanes and the ring-shaped structure around the central cluster. The reddish glow seen in many photographs is primarily produced by ionized hydrogen, while other wavelengths reveal oxygen and sulfur in the surrounding gas. What makes the Rosette particularly fascinating is that it is not simply a beautiful cloud—it is an active stellar nursery where dense pockets of gas and dust can collapse to form new stars, while radiation from existing massive stars simultaneously erodes some of that material.

Are there new images?

Yes—2026 has produced several impressive new images of the Rosette Nebula. NASA featured a new Rosette image as its Astronomy Picture of the Day on February 14, 2026, showing the bright young stars and glowing gas in a striking natural-color interpretation. Amateur and professional astrophotographers have also produced significantly newer deep images. For example, one 2026 image published in January used 15 hours of RGB and SHO observations, producing a detailed Hubble-palette view with intricate gas structures and dust filaments. Another February 2026 observation accumulated more than 6 hours of imaging, while a March 2026 image combined 47 long exposures taken across multiple nights to reveal much fainter structures
