Gemini telescope in Hawaii fixed, captures nearby supernova
Click for original image.
The Gemini telescope in Hawaii, which was damaged in 2022 during normal maintenance operations, has now been fixed and resumed observations, beginning with a spectacular image of the newly discovered supernova in the Pinwheel Galaxy, only 20 million light years away.
The Gemini North telescope, one half of the International Gemini Observatory operated by NSF’s NOIRLab, has returned from a seven-month hiatus literally with a bang, as it has captured the spectacular aftermath of a supernova, a massive star that exploded in the large, face-on, spiral Pinwheel Galaxy (Messier 101). The supernova, named SN 2023ixf [as indicated by the arrow], was discovered on 19 May by amateur astronomer Koichi Itagaki.
Since its discovery, observers around the globe have pointed their telescopes toward Messier 101 to get a look at the burst of light. Over the coming months, Gemini North will allow astronomers to study how the light from the supernova fades and how its spectrum evolves over time, helping astronomers better understand the physics of such explosions.
As one of the closest supernova to occur in years, SN 2023ixf has become a major target by astronomers. This type of supernova signals the collapse and death of a star 8 to 10 times the mass of the Sun. Since the life cycle of such massive stars is not yet fully understood, this nearby supernova provides a great opportunity for astronomers to learn more.

Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.

I still have a bit of cognitive dissonance when astronomers refer to something in another galaxy as “nearby.” Why it’s ONLY 20 million light years away! That a mere 200 trillion kilometers, give or take.
