Gemini Observatory reveals dazzling new Butterfly Nebula image for 25th anniversary

A stunning new image of the Butterfly Nebula has been released to celebrate the 25th anniversary of the Gemini Observatory. The nebula, also known as NGC 6302, lies between 2,500 and 3,800 light-years from Earth in the constellation Scorpius. Its striking shape and vibrant colours have long fascinated astronomers. The Butterfly Nebula formed from the violent expulsion of gas by a dying star. This star was once exceptionally massive. Now, its white dwarf remnant remains, retaining about two-thirds the mass of the Sun.

The white dwarf heats the nebula’s gas streams to over 20,000 degrees Celsius, causing them to glow. Its surface temperature exceeds 250,000 degrees Celsius, making it one of the hottest known stars. High-speed gas streams collide with slower-moving material, creating the nebula’s distinctive butterfly shape.

The image was captured by the Gemini South Telescope in Chile. In the photograph, red highlights regions of energised hydrogen, while blue indicates excited oxygen. The nebula also contains elements like nitrogen, sulfur, and iron, which will one day form new stars and planets. The new image marks a milestone for the Gemini Observatory. The nebula’s unique structure and extreme temperatures provide valuable insights into the life cycles of stars. Its elements will contribute to the formation of future celestial bodies.
