    Wow, Chain - you've got to get on a boat and go see it! I have a whole bunch of friends on a ship off the coast of Australia right now, steaming for the intersection of clear skies and central eclipse line. I'd be there myself but opted instead to purchase a new spectrograph for the observatory. There is nothing else like being on the center line for a total eclipse, a truly stunning experience.

    Do you stand to attention while gazing at glistening orbs at night?

    Don't think today's eclipse will be visable here in NY. Too cloudy / rainy anyway.
    FYI though, Leonid meter showers peak this weekend, particularly Saturday November 17th.

    Only 42-ly away! One day soon, we'll develop telescopes that can peer in on this world and see what was going on 42 years ago. Still, a much more productive use of tax dollars than protecting corporate foreign interests.

    Just wondering if anyone knows...... [I haven't brought out my scope in a while]
    What planet is in the East North America sky... when facing east...... a couple hours after dusk.

    If you have a smart phone, there is an app for that called Skymap. I'm thinking its Jupiter.

    It is. It's in Taurus at the moment.

    If you look early in the morning (an hour or so before sunrise), you should be able to see Venus and Saturn low in the east. And Mars can be spotted in the southwest just after sunset.

    Jupiter I believe

    Perhaps Mars . . .

    Always been a buff myself.
    Everyone remembers the first time they see the rings of Saturn, the moons of Juipiter, a cresent Venus....

And I believe radar can track pieces down to at least 6 inches. (Correct me if I'm wrong on that, please). Satellite photography has a following in the amateur ranks, and it's not too easy tracking them for a picture. How do you spot an unknown object one foot large going 18,000 mph ?? By constantly panning random orbital inclinations up to 90 degrees (polar orbit)?? Good luck finding that big black chunk of #@%^& that doesn't reflect radar. Yes, I saw the shuttle with the tethered satellite, but I say they can't spot and track a piece of the tether alone.

It's a do-not-miss for those interested.
    Sadly, it was announced today of Sir Patrck's passing May he rest in peace.

    I never caught the bug myself, but my dad is one.

    However, I think he was always more interested in building telescopes than actually looking through them. After he retired, he constructed several beautiful and ingenious designs, of which my favorite was a V-shaped refractor: It had a flat mirror about a third of the way along the optical path that turned the path around backwards, so the eyepiece was right next to the declination pivot - as a result, when you changed the declination it changed angle but not height. You could easily sit in a chair as you gazed through it, and not have to constantly shift between sitting, standing, and stooping.

    Always been fascinated by astronomy, cosmology and stuff of that kind. Yesterday, I was reading about this supermassive black hole (not the Muse song) recently discovered...

    "A supermassive black hole, 4,000 times larger than the one at the centre of the Milky Way, has been spotted by astronomers. It lies at the heart of a small lens-shaped galaxy called NGC1277, which is 220 million light years away in the constellation Perseus. The black hole makes up an enormous 14 per cent of the galaxy's mass. Other black holes found at the centres of galaxies account for only about 0.1 per cent."

    I remember Asimov writing about the fact that these supermassive black holes could be used as a one-way ticket to time travel to the future...

    That sounds really cool.

    My feeble brain that's never sniffed a Physics course never ceases to be fascinated and boggled by this kind of stuff. It's hard to even fathom these kind of numbers and sizes.

    Went out last night and watched for a while. Saw maybe 10 meteors in 20 minutes, not bad!

    I watched the skies for a while last night after 11:00 pm. Saw about 15 meteors, including 3 in one small part of the southwestern sky within the course of one second's time. Quite a show. There were no clouds but there was a bit of haze which I think was moisture in the air. So it was not as clear as the previous night, but still plenty of stars. It was 20 F out. When there was a lull in the meteors, I got out some binoculars and was able to see one of Jupiter's moons.

    Last night we were between dust storms here on the red planet.

    I really live in Nevada, USA. But the only drawing I could find small enough to import for an avatar was Marvin the Martian. Someday I will find something else and update my profile accordingly.

    I'm sure some parts of Nevada look just like Mars
