And the Milky Way galaxy is one of an estimated 1 to 2 trillion galaxies in just the observable universe.

We're just a tiny dust grain in the greater scheme of things. That's my feelgood message for the day.

Incorrect. Because we view the Milky Way galaxy from within, we get to see the entire the spiral arm on the outside. Observation is best in the southern hemisphere. Not only that, but our solar system bobs up and down like a horse on a carousel as it orbits Sagittarius A*

Spoilsport. Still, the first sentence stands. Prof Cox says so!

No no, Prof Cox said nothing of the sort. Attached is the text file for subtitles for his BBC Universe show. Read line items 15 through to 21 to enlighten yourself.

"And the Milky Way galaxy is one of an estimated 1 to 2 trillion galaxies in just the observable universe."

Are you saying this is incorrect? Google says slightly different, it says:

2 trillion galaxies

It is estimated that there are between 200 billion (2×1011) to 2 trillion galaxies in the observable universe. Most galaxies are 1,000 to 100,000 parsecs in diameter (approximately 3,000 to 300,000 light years) and are separated by distances in the order of millions of parsecs (or megaparsecs).

Oh, you're talking about the image rather than my sentence I think.

About 2 Trillion????that’s is correct. The scary thing about that 2 trillion is that it only makes up 5% of the observable universe’s make up.

"We're just a tiny dust grain in the greater scheme of things." That could probably be revised downwards..........
