Wow! Our Hubble Space Telescope (@NASAHubble) looked toward the constellation of the Swordfish (Dorado) and captured this stunning celestial image.
Nestled within the Large Magellanic Cloud, this globular cluster – a tightly bound group of stars – features a ruby-red spot that is actually a carbon star. Carbon stars are almost always cool red giants, with atmospheres containing more carbon that oxygen, which is the opposite of our Sun.
Carbon monoxide forms in the outer layer of the star through a combination of these elements, until there is no more oxygen available. Carbon atoms are then free to form a variety of other carbon compounds, which scatter blue light within the star, allowing red light to pass through undisturbed.
