This stunning image shows a fiery object called the Rosette Nebula, located 5,000 light-years from Earth, and was captured by the Dark Energy Camera (DECam) on the 4-meter Víctor M. Blanco Telescope in Chile. The Rosette is essentially a cloud of dust and gas that acts as a busy stellar nursery, containing a prominent cluster of young stars at the nebula's center.
Unlike other telescopes, such as the James Webb Space Telescope, which observe the universe primarily in infrared wavelengths, DECam looks at optical wavelengths, so it can see colors similar to what the human eye can perceive. The colors in the image above are so vibrant and vivid. This is because the light from the massive young stars in the cluster emits large amounts of ultraviolet radiation, which ionizes nearby hydrogen gas. The ionized gas glows brightly, giving the nebula its distinctive appearance.
The billowing red clouds are H-alpha emission regions, caused by high-energy hydrogen atoms emitting a red glow. Along the walls of the central cavity, close to the massive central star, the radiation is intense enough to ionize heavier atoms like oxygen, glowing in shades of gold and yellow. Finally, along the edges of the “petals” are wispy, deep pink tendrils, the light from ionized silicon.
The Rosette Nebula is a very large nebula, measuring about 130 light years in diameter. A hollow region is easily seen in the centre of the nebula, which lacks the red or yellow colour that indicates the presence of gas. This central region has been hollowed out by the process of star formation, when dust and gas form into clumps that gradually attract more and more material through gravity until these clumps collapse into a core that forms the basis of a new star.
These stars formed a cluster called NGC 2244 about 2 million years ago. And as these stars evolved, they created stellar winds that blew away surrounding dust and gas, preventing many other nearby stars from forming.
Such winds hollow out the center of the nebula and will eventually lead to its demise. Over the next 10 million years, radiation from these stars will blow away so much dust and gas that the nebula will disappear, leaving only stars without the rosettes surrounding them.
