The closest cosmic explosion to Earth within the last 10 years became a record breaker for the Seek for Extraterrestrial Intelligence (SET) Institute.
The supernova, designated (SN) 2023ixf, was first spotted on May 19, 2023, by Japanese amateur astronomer Koichi Itagaki. Just an hour after this manifestation, amateur astronomers collaborating in SETI and Unistellar’s Cosmic Cataclysms program were on the case.
A record variety of observers, including citizen scientists in the shape of amateur astronomers, got here together to gather data from a supernova that took place within the Pinwheel Galaxy, a spiral galaxy situated roughly 21 million light-years from Earth.
With the info, scientists could higher understand the behavior of this class of supernovas generally known as Type II, cosmic explosions that occur when massive stars run out of fuel for nuclear fusion and may now not protect themselves against gravitational collapse.

“It is de facto incredible what this citizen science network can do,” SETI Institute researcher Lauren Sgro said in an announcement. “This was the closest supernova of the last decade, and observers took full advantage of the special day. They jumped on track as soon as possible and kept observing, which allowed us to witness the total potential of this program.”
The hassle involved 123 dedicated amateur astronomers making 252 observations with 115 telescopes following how light from the supernova modified over time, first seeing its escalating brightness after which tracking its gradual fading. This allowed the SETI scientists to construct a profile for the supernova that astronomers called a lightweight curve, a measurement of its brightness over time.
And the story is not over for (SN) 2023ixf. The supernova is anticipated to stay visible until a minimum of August 2023, and while that is the case, the amateur astronomers of the Cosmic Cataclysms program will proceed to observe its progress.
Leveraging the ability of amateur astronomers
The Cosmic Cataclysms science program is a joint undertaking between the SETI Institute and Unistellar which is funded by the Richard Lounsbery Foundation and the Gordon and Betty Moore Foundation. This system lets citizen scientist astronomers study and collect data from cataclysmic events and rapidly changing or “transient” events akin to supernovas and gamma-ray bursts.
Participants receive real-time alerts when transient events are spotted, leading to the rapid initiation of observing campaigns akin to the one seen for (SN) 2023ixf. As they monitor the rise in brightness and subsequent fading of cataclysmic events, volunteers help scientists to collect vital details concerning the objects behind these violent and powerful celestial occurrences and their impact on surrounding gas and dirt, generally known as interstellar material.
This system will get a serious boost next 12 months when the Vera C. Rubin Observatory in Chile commences operations, allowing the Unistellar network of citizen astronomers to team up with other crews of astronomers and skilled astronomers to check transient events.
The team’s research was published within the journal The Research Notes of the AAS.
