Messier 101 - Pinwheel Galaxy with Supernova SN 2023ixf imaged and processed by Craig Stocks at Utah Desert Remote Observatories. One of the most notable ways amateur astronomers contribute is through extragalactic supernova searches. Supernovae are crucial for understanding the evolution of galaxies, and amateur astronomers often participate in systematic monitoring of distant galaxies to detect these brilliant cosmic explosions. Their unique advantage lies in the time and dedication they can commit, often using their own equipment. The observations and data collected by amateur astronomers provide a wealth of information that can complement professional research, aiding in the study of supernova properties and their impact on galactic ecosystems. Exoplanet research is another field where amateurs can play a pivotal role. While professionals have access to state-of-the-art telescopes and instruments, amateur astronomers can contribute by regularly monitoring stars for the telltale

The author's artistic rendition of the "Great Fireball of '66". At around 7:15pm, on Sunday, April 24, 1966 – fifty-seven years ago this past April - I was 8 years old, and I just happened to be passing by the open front door to our house, in Falmouth, Massachusetts, facing, due, West...If I had been doing anything else - other, than that – I could not be writing this today… This is my digital painting/impression of the “Fireball”, as I observed it from my front door-step, super-imposed onto a photo of the Mullen-Hall School, in Falmouth, as seen from my perspective. I remember that the sky was still light, and absolutely cloudless (about 30 minutes after sunset) when I noticed a bright ball of light about the size and brightness of the full moon approaching from my left in my field of view (toward the South). I remember being, "frozen", in place, as I watched this bight, "thing” – I first thought it was maybe a burning aircraft, moving parallel wit

The Leonid meteor shower occurs annually in November, peaking around November 17th. To make the most of this celestial spectacle, here are some tips on how to observe the 2023 Leonid meteor shower. The Leonid meteor shower, renowned for its stunning meteor displays, originates from the debris left behind by the comet 55P/Tempel-Tuttle. This comet, which takes approximately 33 years to complete its orbit around the Sun, sheds dust and small rock particles as it travels through our solar system. Over time, these remnants disperse along its orbital path, forming what is known as the Leonid meteoroid stream. When Earth intersects this stream each year in November, the particles collide with our planet's atmos
