Another breath taking picture, nothing makes you appreciate the cosmos more than living in a concrete jungle, smothered in light pollution.
Thank you Bud, and APOD for taking my breath away once again.![Very Happy :D](./images/smilies/icon_biggrin.gif)

Vision, I don't think we've had telescopes that are capable of letting us view other galaxies for long enough to observe it. Even if we had telescopes 10,000 years ago, cameras didn't get invented until just a few hundred years ago, and photographic cameras only started to come around a little over...

Thats an interesting theory, if galaxies are tumbling though should we not see some movement over a long period of time? Also what would they tumbling towards? I tthink if galaxies were spinning on more than one axis, it would be fairly apparent, even though it would probably take billions of years ...

I think the question is why are spiral galaxies not all oriented in parallel planes. We cannot see the entire universe from earth, but we can see a spherical portion of the universe from our vantage point with a radius of about 12.7 billion light years. Imagine if we did a survey of all the visible...

Multiple planes of space
I,m not quite sure how to word this, but i,ll try my best. With the countless stars in a given galaxy all bound together by gravity, I find it very interesting that the gravitational "plane" these stars are all orbiting around differ in terms of their hypothetical ground plane. I guess wha...

Re: Comet Encke's Tail Ripped Off (APOD 03 Oct 2007)
http://antwrp.gsfc.nasa.gov/apod/ap071003.html Wow!! It looks like the coronal mass ejection occurs in three waves. The first wave almost carries the comet tail away, the second wave knocks the tail off completely. By the time the third, smaller wave passes, the tail has grown back. It really makes...

Hole in the Sun (APOD 27 Sep 2007)
I find this very interesting, if this cosmic radiation is deflected around us by our planets magnetic field(protecting us from being burnt to oblivion, but also putting on a spectacular light show in the northern regions of our planet),I always wonder, is it possible to harness this tremendous power...

I am not sure about the validity of this image
impactor? on the moon?

edit: some of these craters seem quite shallow, and although most likely ancient, no impactors? low denisty impacts at high velocities?

This sight had a good theory about Hyperion. I assume you were talking about its surface.

After seeing today's APOTD
If our own atmosphere burns up a large amount of any in bound impact, why is it that on other moons and planets lacking such 'atmosphere' (I use that term loosely :D) , there are for the most part no remnants other than impact craters? I realize there is some 'atmosphere' on these planets, but even ...
