![]() ![]() ![]() The telescope’s primary mirror was damaged in October while it was being moved, sustaining a chipped edge. The new image taken of the supernova’s aftermath by the Gemini North telescope in Hawaii marks the observatory’s first return to scientific observations after a seven-month hiatus. It’s the second supernova observed in the Pinwheel Galaxy in 15 years.Īstronomers are using telescopes to observe the newly discovered supernova to better understand how stars explode and track how the brightness of the explosion evolves and fades over time. ![]() Astronomers believe it is a Type II supernova, when a massive star between eight and 50 times the mass of our sun exhausts its nuclear fuel supply, collapses and explodes. The new supernova glimmers bright blue in one of the galaxy’s spiral arms in the bottom left of the image. Dark dust regions are used as one of the key ingredients for star formation. The blue points of light in the image taken by the Hawaii telescope reflect the population of young, hot stars. The galaxy’s spiral arms are full of nebulae, or regions where stars are born, showcased in pink light. The galaxy faces Earth head-on, which showcases its stunning spiral structure and nearly 1 trillion stars. The Pinwheel Galaxy is in the direction of the Ursa Major constellation, about 21 million light-years from Earth. Webb telescope captures ‘green monster’ inside a young supernova This new image uses data from Webb's Mid-Infrared Instrument (MIRI) to reveal Cas A in a new light. Cassiopeia A (Cas A) is a supernova remnant located about 11,000 light-years from Earth in the constellation Cassiopeia. ![]()
