"NGC 253 lies only about ten million light-years distant."ONE light year, the DISTANCE light travels in a year at the speed of 186,000 miles per second, works out to about 6 TRILLION miles.

It must have a permit from the EPA.

Only ten million light years? Just a short jaunt down the inter-galactic highway.
It still amazes me, that given the number of galaxies out there, the number of stars in each galaxy, even with the physical limitations required for life to exist, some people persist in maintaining that our tiney speck of dust is the only inhabited world.

Dust credits — more than we could ever sell ‘em.

A Black Hole-Powered Spiral Galaxy
NGC 7742
The term "black hole" is a region of space from which nothing can return.
A black hole is a concentration of mass great enough that the force of gravity prevents anything past its event horizon from escaping it. The gravitational field is so strong that the escape velocity past its event horizon exceeds the speed of light. This implies that nothing, not even light, inside the event horizon can escape its gravity. It is, however, theorized that wormholes can let one exit a black hole. Objects in a gravitational field experience a slowing down of time, called time dilation.

Except its gravity.

Last time I was out with the scope, I took a peak at 253. It’s VERY large and bright. It crosses the meridian right at sunset now.
At the same time I was looking at 253, the guy who owns the land we were using was imaging it with his set up. His pictures look much more like those posted than my view in my 10inch.

So we’re only 2.5 “Light Dollars” in debt. No wonder Obama thinks we can spend more, 2.5 seems a low number.

Last time I was out with the scope, I took a peak at 253. Its VERY large and bright.Of course you saw it as it was about ten million years ago, as it took that long for the light/image we see today to arrive here. I know you know you this, but others may not realize it.

Well Yes.
A Telescope is a time machine. You can look into the past and only see what was. Even the stuff that is close to us (even in the solar system) is time delayed.
