1. Denis O' Sullivan on 4FM How many people have seen with their very own eyes, something which has left Earth, flown in outer space, landed in another world, and then come back down again? Here is YOUR chance. Our Easter Lecture speaker will bring along an experiment carried to the Moon for him by the Apollo astronauts, and brought back to Ireland again. Professor Denis O' Sullivan of the Dublin Institute of Advance Studies (DIAS), will give an interview on 4FM Friday April 17, ahead of the Easter Public Lecture he will deliver next Monday. Prof. O' Sullivan will speak on the new multi-city radio station at 7:40am, giving listeners a sneak preview into the content of Mondays lecture - From the Moon to Matroshka - a highly significant space experiment he is currently running. You can listen to it worldwide online at www.4fm.ie or, if you miss the interview in the morning don't worry, you can listen to it HERE. Prof. O' Sullivan's lecture takes place at 8pm next Monday April 20. Tickets are 7euro (non-members) or 5euro (members and concessions). A DVD of the lecture will be available for purchase for everyone all over Ireland at a cost of 7euro (plus p&p).

Astronomy Tips for April Saturn Events: Have you been missing a once in 15 year event? Those of you with telescopes have been getting amazing views of Saturn, its moons, and its rings which are nearly edge on this year. Did you realise that this means the moons pass in front of, and behind the planet in events that can only be seen every 15 years? Lots of you have telescopes capable of seeing this and we want you to report your sighting to observe@astronomy.ie. Indeed, we saw Rhea skimming above the rings just after it had passed in front of Saturn on April 4 at our 100 Hours of Astronomy event (see HERE). And remember, Saturn is a fine evening object for this month, all of May, and most of June, so dust off your scope and get a once in 15 year view! Jupiter is visible in morning skies. It's near the Moon this Sunday and Monday morning - see the diagram in our April magazine, page 22. Deep Sky: Remember, the Moon is out of the sky so all those of you with the simple-to-use 3-star alignment telescopes can use "tour" to see thousands of galaxies, star clusters and gas clouds in the coming weeks! Call the Shop for quick advice on how easy this is. You can find a list of all celestial events in the Sky Diary and Sky map pages in 'Astronomy & Space', our full-colour monthly magazine, which shows that there are several events to see almost every night of the month!
