The Most Extreme Dangerous Stars In The Universe
What are Wolf-Rayet stars?
Wolf-Rayet stars are evolved stars that have exhausted most of their nuclear fuel and are close to the end of their lives. They have masses of at least 20 times that of the Sun and have surface temperatures that can reach up to 200,000 degrees Celsius, making them some of the hottest stars in the universe. They are also extremely luminous, with some Wolf-Rayet stars having a luminosity that is millions of times greater than that of the Sun.
Wolf-Rayet stars are characterized by their strong stellar winds, which blow off their outer layers of gas and dust at a tremendous rate. These winds can have speeds of up to 3,000 kilometers per second and can carry away up to 10^-5 solar masses of material per year. This process creates a nebula of gas and dust around the star, which can be seen as a beautiful, glowing cloud in space.
