NGC 261 is situated within the Small Magellanic Cloud, one of the Milky Way’s nearest galactic companions. NGC 261 shines with a brilliant ruby red in this new image from NASA’s Hubble Space Telescope, set against a backdrop of countless stars. Discovered on September 5, 1826, by Scottish astronomer James Dunlop, this nebula resides in the Small Magellanic Cloud (SMC), one of the Milky Way's closest galactic neighbors. Classified as an emission nebula, NGC 261's vivid pinkish-red glow is the result of ionized gas emitted by hot, young stars within the nebula, which energizes the surrounding hydrogen gas. This inset image highlights the position of NGC 261 within the Small Magellanic Cloud. HHubble turned its attention to NGC 261 to explore the efficiency of star formation within molecular clouds—dense regions of gas and dust that are crucial for star birth. These clouds are primarily composed of molecular hydrogen, the main ingredient for star formation, but are challenging t...
