another 'once in a lifetime' comet.

I've seen 2 of them and so this isn't exactly 'once', except maybe for him?

hmmm... come to think of it, I sure hope it's visible over here. thus far we've missed 2 lunar eclipses.

It always kills me when artists draw comets with the tail facing in the wrong direction.

Had an idiot teacher once who had it bass ackwards too, and an explanation he used to explain why he was right. I think some of the students believed him too.
He said the tail of a comet is always between the comet and the sun, because the sun burns the gasses. If it were on the other side, the comet would shade the gasses from the sun. WRONG!

A comet has two tails, the arched dust trail and the straight ionized gas tail, and both face away from the sun, due to the solar winds. It's a bit more technical than that, but for a simple explanation, it will suffice.

I observed this phenomenon up close when Dr. Who took me for a ride in his Tardis. SMILEY BELONGS HERE!

I'm using Ubuntu again today, and it is riddled with things that do not work as they should.

I just came back to test something. I'm on Debian 7 and returned to add my smiley ☺, and as you can see, it works from Debian 7, but not from Ubuntu 14.04. So, using standard Unicode Characters is something they don't want their users to use either.
I was just telling Yogi in another post. Ubuntu does not want their users to have access to Root. Even if you get in Root to work on a system file, it won't let you get to those files.
Looks like Ubuntu is trying to emulate Windows 8.1. Another major downgrade for Ubuntu.

Maybe Ubuntu should change their logo to ♿... Since it is now a cripple!

:lol: @ icy!

I've been thinking about getting another telescope... I wonder what a decent one would cost...? I had an old but good make, then decided to get a new fancy one that I never even learned to use before the fire took it... :bleh:

hm... I wonder what ebay has to say...

You'd probably be better off looking on there. Decent - even first-time telescopes - can be expensive now, especially if you want one which automatically zooms in on what you want to look at. You just pop the info in, and there you are.

Here's an example ...

Obviously you can buy them, but a secondhand one in good working order might be better than a brand new one that has no far-reaching capability. A good telescope can last for years.

Good idea to get the kids interested in astronomy though.

I used to know most of the biggest stars, planets and constellations when I lived at my house and they didn't move around so much. :grin:

now... "oh look, it's the big dipper..."

I used to know the same. Now I've pretty much forgotten, because I don't study the night sky anywhere near as much as I used to.

Yes, probably one of the best views you can get.

I want to go up and have a good look at the northern lights; here they're pretty insipid and I think I've only seen them once.

and! there they come with sound effects: like loud crackling. I've never heard that.

How weird. I'm surprised you can see them at all from where you are. We can't from here.

Oh you've set me off now. I'll have to look into the flying thing, and then maybe we could go to Finland and have a look!

I've seen them up there, but it was apparently the wrong time of the year to get a good display.
