Re: Asteroids, meteors, and meteorites

I wonder if we can make predictions for incoming space garbage too, we've had a few incidents of that also.

I've always wanted to collect meteorite fragments but didn't know what kind of equipment I'd need to identify it in the field.

Re: Image Dump

Maybe the ship got eclipsed?  Stunning views nonetheless!

Re: Image Dump



Wow I need to find distinct colors like these!
I've been looking for multiple star systems like that.

Well, you have a lot of addons, and may have changed the default addresses, so this may not work for you:

The planet I'm orbiting is:

RS 8093-2251-8-8180399-2344 B1

2.904 day orbit around ...

Re: Science and Astronomy Questions

But that doesn't equate a torus with a sphere, they are topologically distinct....but this has already been discussed.  The random inclination variation (which I didn't know about before) is why it's a sphere and not a torus.

Re: Global population hits 8 billion


I take bigger issue with calling it "the sixth mass extinction" than recognizing that the extinction rate is currently significantly greater than the "background extinction rate". The latter is a strong claim to make, especially given the biases in determining past extinction rate from the fossil ...

How do you get such vivid contrasty colors, Fellow Alex?

Re: Global population hits 8 billion




Ahhh its not that little, space makes it look liitle.
Earth is plenty big enough for us right now, we simply have to get some perspective and work on our existing technologies to do things better.
In fact things are alot better than they have been in the past.
Getting us all out of poverty and ...

Re: Show off your work



This is ironic! We just had an earthquake this morning (only 3.8) in the opposite part of the state-- in Buffalo!
Can such a weaker distant earthquake also be detected using this method, Mid?


A 3.8 is way too weak for a camera observation like this. But this instrument itself can detect such ...

Re: Science and Astronomy Questions


Mid, are they even sure about that period? I read that they aren't even sure if it will ever return. Maybe it has a parabolic path or even hyperbolic?
Its orbit is changing during its plunge through the solar system. Inbound its eccentricity was slightly less than 1 with an orbital period of ...

Re: Science and Astronomy Questions


It's a faint comet (I don't really understand the hype, which seems to be centered around that it has an orbit of 50,000 years (quite roughly?), but I digress). But I was able to find it in video from a meteor camera, despite exposure times of 1/25 second. It was supposed to be magnitude 4.5, but ...

Re: Science and Astronomy Questions



I know, but in my light polluted part of the country, the only thing that I can really see from here are stars (and only the really bright ones) so it would be interesting to see a green object in the sky. The only other comet I've ever seen was Hale Bopp.

Even with binocs and from a dark sky ...

Re: Science and Astronomy Questions



Exactly. :) We use belts to describe diffuse but disk-like distribution of objects, and clouds for diffuse but more spherical distribution of objects.
Is it really spherical though or more like a torus? I always envisioned it like a torus because there is the "hole" in the middle (where the ...
