And the edge of our galaxy is 75,000 light years away, and the nearest galaxy to us, 2.5 million light years.

M71 is at a distance of about 12,000 light years away from Earth and spans some 27 light years across.

It is located 97 light years from Earth.

The stars next closest to the Sun are the red dwarfs Barnard's Star (at 5.9 light years), Wolf 359 (7.8 light years), and Lalande 21185 (8.3 light years).

The Horsehead Nebula is approximately 1500 light years from Earth.

It is approximately 182 light years from Earth.

A parsec is 3.26 light years.

13.8 billion light years The age of the universe is estimated to be 13.8 billion years.

(Music with lyrics)

We are 12 billion light years from the edge.

M47 is at a distance of about 1,600 light years from Earth with an estimated age of about 78 million years.

This is because Sirius is merely 8.6 light years from the Earth, while Canopus is much farther away at a distance of 310 light years.

M75 is at a distance of about 67,500 light years away from Earth and its apparent size on the sky translates to a true radius of some 67 light years.

And at this point we've come 100,000 light years from here.

So it takes light three billion years to travel over that distance.

And at this point, we've come 100,000 light years from here.

(Music) (Lyrics) We are 12 billion light years from the edge

I think it quite likely that we are the only civilization within several 100 light years.

So that star is also 50 million light years away.

And the nearest star is 4.2 light years away, which means its light takes 4.2 years to get here.

In America it would be, We're 6,000 light years from the edge.

You know, it's 12 it's 13.7 billion light years, and it's not a guess.

The star is located about 5000 to 6000 light years from the Earth.

At least she got it close. In America it'd be, We're 6,000 light years from the edge.

You know, it's 13.7 billion light years, and it's not a guess.

So a gigaparsec is three billion light years that's the scale.

The nebula lies at an estimated distance between 6,500 and 10,000 light years from Earth.

It is roughly spherical, about 20 million light years in diameter and contains more than 3,000 galaxies.

This is about 50 million light years away, so one of our neighboring galaxies.

Beyond Neptune lies the Kuiper Belt, and finally the Oort Cloud, which may extend as far as a light year.

The two stars do not form a binary star system as 35 Leo is only 100 light years from Earth.

It is classified as a semiregular variable star and its brightness varies from magnitude 2.99m to 3.33m.

It is located relatively close to the Sun, at a distance of 16.1 light years.

So if the matter that originally emitted the oldest CMBR photons has a present distance of 46 billion light years, then at the time of decoupling when the photons were originally emitted, the distance would have been only about 42 million light years.

One of the rings, caused by a major eruption, is a shock wave in diameter around the black hole.

This arises from the light from three galaxies at distances of 3, 6, and 11 billion light years.

IGR J17091 3624 (also IGR J17091) is a stellar mass black hole 28,000 light years away.

So, 100 billion galaxies, 13.7 billion light years away a step in size from that to Monterey, actually, is about the same as from Monterey to these things.
