They are fantastic... wish I had a telephoto on my digital camera...... Lovely. ..... I was actually going to mention somehitng similar a few weeks back concerning Jupiter, and decided against it...... but this is more classic. Thanks -cvj Amara, you are so correct!

I think its handy that both are visible in the same region of the sky, so they can see the objects while on telescope/binocular field trips too. A handout of the basics, plus where they can find the objects (M1=Crab Nebula and M42=Orion Nebula in the chart) in the sky (Rome lat/lon.) can be downloaded here: http://www.amara.com/CrabandOrion.pdf (2Mb) P.S. those of you on the other side of the Atlantic, try to look up after sunset; the Moon (thin crescent) and Venus are especially lovely tonight.

We see better. Do we understand the "gravitational waves" generated any better? A more detailed look into the geometry happening from LIGO about the dynamics in a cosmological way?
