Hi all,ƒŠ
ƒŠ
1: Lyrid Meteors tonight & tomorrow night: The Lyrids are not one of the year's best showers, but for observers in our latitudes they are the best shower in the long 'Spring Gap' between the Quadrantids in early January and the Perseids in August. There are other showers in that period, but they are either very minor, or affected by the long summer twilight, or only visible briefly low in the pre-dawn sky. They originate from Comet Thatcher, and some experts predict a slightly better than usual display this year - maybe 25-30 per hour in good conditions. The radiant is near Vega, but they can appear anywhere in the sky. Maximum is predicted for around 24h BST on April 22/23, and the 4-day old Moon will not be a problem, so the prospects look quite good.

4. Another great COSMOS: Congratulations to MAC for yet another superb COSMOS star party last weekend in Athlone. There were excellent speakers; 2 clear nights for observing; an enjoyable coach trip to Birr Castle to see the great Leviathan, the Rosse radio solar observatory; and the site for the ILOFAR radio telescope if it gets the funding. There was a superb main prize in the raffle, donated by KTEC Telescopes; some great craic at the quiz after a lovely dinner (won yet again by Patricia Carroll & her team!) Finally, there was some great fun with Bob Campbell's formidable 4-way rocket launcher, with Angela O'Connell's rocket performing best (did I mention that I made it....?) Thanks and well done to all, particularly Seanie Morris, Jason Fallon & Declan Molloy.

6. ARCHAEOASTRONOMY TRIP TO NEWGRANGE and KNOWTH, May 9ƒŠ
These trips have proved so popular that as soon as I got back from the last one, Stranmillis University College Institute of LifeLong Learning asked me to lead another one. Like the last one, this trip will include a visit to the Knowth Tomb as well. It has the largest collection of Megalithic art anywhere in Europe in one single site, some of which is reckoned to be astronomical. Booking for thus very popular, non-technical trip will open later, but if you want to go, note the date in your diary: Sat 9 May.ƒŠ

http://www.dailymail.co.uk/sciencetech/article-3037521/Is-universe-slowing-Supernovae-suggest-expansion-cosmos-not-fast-thought.html I've been saying this might be the case for years! NB, the two photos of M101, with the optical one on the Left (not right as in the text) are at slightly different scales, and orientations. The Swift image (on the right) is rotated about 15 degrees anticlockwise compared with the optical photo.
http://www.dailymail.co.uk/sciencetech/article-3048578/Watch-Rosetta-s-comet-BURP-Geyser-seen-suddenly-erupting-surface-amazing-chance-discovery.html The comet is often compared to a duck in shape. But judging by the position on the duck's anatomy, that's not a burp.....!

How does light use up more energy to enter & cross an area where the density of matter is lower? Should it not be the opposite?
