I read this as the distance shown between the two sides of the image.This deep Chandra Observatory x-ray image spans about 300,000 light-years across the galaxy cluster core.

ta152h0 with the right technology, yes they would be visible :) and no, we don't currently have technology like that... and although planets can be detected indirectly through gravitational micro lensing and doppler shifting, these techniques currently require the planets to be both very large and a...

If the moon was created by a cataclysmic event as theorized, it may not. Aren't we pretty confident it was created by a cataclysmic event - a mars sized body striking the early Earth? That aside, the earth itself was created through a series of cataclysmic events! The process of accretion can be qu...

A great view
The Horsehead nebula up close.
http://www.space.com/images/besthubble_horsehead_02.jpg
At the top left of the horse shape you can see a star embedded in the cloud - illuminating it. (unless I am mistaken)
I imagine there would be a stunning view from a planet orbiting that star!!!

that is a fantastic picture!

but I really can't see the hourglass formation in the bubble nebula - although I see the similarities you are pointing out.

could be thats it very low gravity prevents collisions of adequate force to form major craters, and it has just been lucky not to be hit by anything (recently) with a high relative velocity. the mechanics of dust and debris settling in an environment with gravity that low could be very different to ...

with a one on distance-squared relationship for the force exerted on objects by gravity it would seem to me that another galaxy would have to float very much straight through to have the center taper out as it does in that image (i expect it is stretched in the direction of movement of the colliding...
