NGC 6551 is a planetary nebula located in the constellation of Scorpius. It was discovered by the astronomer William Herschel in 1786. This nebula is notable for its bright central star, which is a remnant of a dying star that has shed its outer layers, creating a colorful shell of gas and dust. The nebula is approximately 2,000 light-years away from Earth and has a diameter of about 0.5 light-years. Its distinct shape and vibrant colors make it an interesting object for both amateur and professional astronomers. Observations of NGC 6551 contribute to our understanding of stellar evolution and the life cycle of stars.
