Astronomers using the Gemini North telescope's 'Alopeke instrument have directly detected a close-in blue-white companion star orbiting Betelgeuse, explaining its six-year brightness variability and providing new insights into the life and future death of this red supergiant star.
A new supernova, SN 2023ixf, has been discovered in the Pinwheel Galaxy by Japanese astronomer Koichi Itagaki. The supernova is the closest one seen in five years and is believed to be a Type II supernova. Astronomers are using telescopes to observe the supernova to better understand how stars explode and track how the brightness of the explosion evolves and fades over time. The image of the supernova's aftermath was taken by the Gemini North telescope in Hawaii, which has resumed its search of the night sky for cosmic phenomena after a seven-month hiatus due to a damaged primary mirror.
The 8-meter Gemini North telescope, located on Mauna Kea in Hawai‘I, has returned to service after seven months of repairs and refurbishment of its primary mirror. Just in time, it captured the brand-new supernova in the famous Pinwheel Galaxy. The bright supernova was first discovered on May 19th, and astronomers plan to make more observations with the Gemini North telescope of this supernova over the coming months, studying how the light from the supernova fades and how its spectrum evolves over time.
Gemini North, part of the International Gemini Observatory, has returned to observing the night sky following the repair and refurbishment of its primary mirror. Its debut observation captured the closest supernova seen in the past five years, SN 2023ixf, located in the Pinwheel Galaxy. The telescope's exceptional spectroscopic capabilities will allow astronomers to study how the light from the supernova fades and how its spectrum evolves over time, helping them better understand the physics of such explosions. The successful repair of the mirror is a great team effort for NOIRLab and its contractors at Safran-Reosc.
The Gemini North telescope on Hawaii’s Mauna Kea volcano has captured a stunning image of the closest supernova seen in the past five years, SN 2023ixf, which appeared in the outskirts of the Pinwheel galaxy on May 19, 2023. The supernova is a type II, triggered by the release of energy from a massive supergiant star that pushed its layers into space, leaving behind a collapsed core—a neutron star. The Pinwheel Galaxy is a face-on spiral galaxy in the constellation Ursa Major, around 21 million light-years distant.
