It's full of stars!

1) Take a digital picture several times for 24 hours??

2) Piece these together??

3) Do this same procedure at set points on the longitudal line (using whatever mathematical model dictates (e.g. c=Pi x d)??

4) Piece these together??

5) Eventually the whole circumference of the Earth will have made a 2D picture of the space we can see??

I know I have forgotten the trouble of seeing distant galaxies via the visible wavelength, which I understand they see with other wavelengths the human eye cannot perceive?????!!!!!!

Hmmm.

Griffith Observatory here in LA has a display of a huge wall with a hubble image of space with stars and galaxies. Then you read the information next to it and see that it's a pitifully small sample of what's out there. Of course this was seen after the movie they show in the dome and by the end you're just blown away by the scale of the universe.

The trite answer is that you label the first star with the numeral '1', the next with '2' and so on, until you have counted all of the stars.

The trouble with that is, that new stars are being born, so you would have to keep going back and starting again. Mind you some are dying also.

I graded a few hundred objects on Galaxyzoo.

You also have to take in account that we're rotating so trying to track just one star and then the next is almost impossible. That's also the amazing beauty of it when you realize how insignificant we are in space and time.

Do you in addition make your own observations using a telescope?

Just Binoculars & The Sky at Night.



Mrs & I once went on an amazing trip to NW Australia in the dry season.
The air was completely clear with 0% humidity & no light pollution.
The fella running the trip had three good telescopes & was an astronomy expert.
It was amazing!

A few years ago I made a trip to Namibia, where the conditions for stargazing are excellent: every night was clear, there was no light pollution, the atmosphere was dry and transparent and the seeing was very good. The Milky Way overhead was bright enough to read a newspaper .

At home, only the moon, the planets and many double stars are satisfying objects. Nevertheless I enjoy the views through my telescope, a 180mm Cassegrain made in Japan by Takahashi.
