|Star Formation Region Gum 41.|
This new image from ESO’s La Silla Observatory in Chile reveals a cloud of hydrogen called Gum 41. In the middle of this little-known nebula, brilliant hot young stars are giving off energetic radiation that causes the surrounding hydrogen to glow with a characteristic red hue.
This area of the southern sky, in the constellation of Centaurus (The Centaur), is home to many bright nebulae, each associated with hot new-born stars that formed out of the clouds of hydrogen gas. The intense radiation from the stellar new-borns excites the remaining hydrogen around them, making the gas glow in the distinctive shade of red typical of star-forming regions. Another famous example of this phenomenon is the Lagoon Nebula, a vast cloud that glows in similar bright shades of scarlet.
