Appreciating SDV-XVI
- by Alan Pasicznyk
Try to imagine a birthday cake without the icing, an ice cream sundae without the cherry, or M-104 without a dust lane, and you would pretty much have imagined our annual star-party Stella Della Valley without door prizes! This year Meade Instrument Corp-oration was very generous in supplying us with a complete telescope and tripod for our Grand Prize. Please consider them and all the other donors listed when making your next purchase of any Astronomy related products, as they are indeed good friends of this event.
As for the star party itself, it was well attended with well over 70 people at least. [The final count was 110 attendees. -ed] Friday night was clouded out as the weather bureau had predicted, but Saturday was crisp and clear, and the predicted clouds and thunderstorm just didn't happen. The flea market and guest speakers went on as planned, and after the pizza banquet, emcee Linda van der Spek awarded the door prizes. BMAA member George Reagan, an avid observer and public starwatch volunteer, won the Meade telescope.
The skies Saturday night continued to improve all through the night, with each consecutive hour showing less light pollution and darker sky, so much so that edge on galaxy NGC 891 was visible through my four and a half inch reflector around midnight. I talked to other attendees who remarked that I had gone to bed too early..."You should've seen the sky at 4:00 AM!"
We were all greeted by a nice sunny day Sunday, so that we could dry our camping gear and pack up to go. There was, however, a
Stella Della Valley "first" for me. On Saturday night we were virtually dew free until about 12:30 AM. And it was warm enough
that all you needed that night was a flannel shirt. Sure hope it's that way next year.
And finally, on behalf of SDV co-chairs Ed Radomski, Antoine Pharamond, and Bob Black, our sincerest thanks to all the BMAA members who unselfishly gave their time and effort in running this event and making it a success...
THANK YOU!
Clear skies, Alan Pasicznyk

Black Holes: Feeling the Ripples
Astronomers have finally confirmed something they had long suspected: there is a super-massive black hole in the center of our Milky Way galaxy. The evidence? A star near the galactic center orbits something unseen at a top speed of 5000 km/s. Only a black hole 2 million times more massive than our Sun could cause the star to move so fast. (See the Oct. 17, 2002, issue of Nature for more info.) A new space telescope called LISA (short for "Laser Interferometer Space Antenna") aims to find out. |
Designed by scientists at NASA and the European Space Agency, LISA doesn't detect ordinary forms of electromagnetic radiation such as light or radio waves. It senses ripples in the fabric of space-time itself - gravitational waves. Unfortunately, these waves are hard to measure. If a gravitational wave traveled from the black hole at the center of our galaxy and passed through your body, it would stretch and compress you by an amount far less than the width of an atom. LISA, however, will be able to detect such tiny compressions. With such sensitivity, astronomers might detect gravitational waves from all kinds of cosmic sources. The first, however, will probably be the weightiest: super-massive black holes. Will "feeling" the ripples from such objects finally solve their mystery, or lead to more questions? Only time will tell. Scientists hope to launch the LISA mission in 2011. |
