On March 4th, 1979, NASA’s Voyager 1 spacecraft took the first photos of rings around Jupiter. This was the first time anyone had seen Jupiter’s rings.
Because Jupiter’s rings are so thin and faint, it’s extremely difficult to see them from Earth with ground-based telescopes. Even for a spacecraft out near Jupiter, the rings are essentially invisible unless the cameras look at them edge-on or from an angle where sunlight shines directly through them.
Since Voyager 1 first saw the rings, other space missions like Juno and Galileo have continued to study them. Scientists believe that the rings formed by comets colliding with Jupiter’s moons and kicking dust into the planet’s orbit.
Monday 21st January from about 4 to 6 am
Club members gathered at 4:15 on Patricks Hill to witness a total eclipse of the Moon. Totality lasted from 4:40 to 5:11. After an unpromising start they were rewarded with a moderately clear night.
Thinking of asking for or giving a telescope for Christmas? Cork Astronomy Club has a word of advice to offer: don’t! Or at least, not until you have attended our “What telescope” workshop on Saturday November 17th.
What type of telescope? Dobsonian, Newtonian, go-to? Or would binoculars be better for you? How much to spend? Is there such a thing as a beginner’s scope? Where do I buy it? … So many questions … and one place to get the answers … Tony Jackson’s “What telescope” workshop on November 17th, at Tory Top Library, 2:30 pm. Our Club has no connection whatever to any business and you will receive impartial advice from an expert amateur astronomer. Not a Club member? You can still come, and it’s free, but need to book, please email firstname.lastname@example.org.
The open night will be hosting workshops, a Gravity Well to show how space is warped by large objects, demonstrations on Stellarium (a free software that helps you to explore the night sky) and observing in the courtyard with telescopes brought by Club members. (weather dependent!)

19:00 – 20:00 – Prof Robert Walsh: A talk in the area of solar science and our relationship with the Sun
