Hello everyone.
I haven't ever lived in a dark sky area, so have little opportunity to stargaze seriously. My family didn't have the means for pursuing astronomy as a hobby but I was allowed to watch 'The Sky at Night' in the holidays. It's a British TV programme which has been running for over 50 years and was shown after 11.00pm when I was young. The sheer size and complexity of the universe and the idea of leaving earth fascinated me and I read a great deal of science fiction. It's amazing to remember how much more we know than when I was a child and how much more there is to learn.

My maths isn't up to the standard of being able to qualify to work in the field but I continue to be interested. Comets, transits of the sun, eclipses are possible to view even without clear skies and a telescope. One unforgettable experience was to stand with my daughter and husband in the south of Australia and see a starlit sky as we'd never seen it before. It's sad that there's so much light pollution in the world. I was given the APOD link by a fellow poster on Goodreads and I think of her daily, grateful for the pleasure of seeing the fascinating pictures on the site. Long may it flourish!

Hi. Alan H from Henderson Nv via chicago I’ll. On the lakefront in chicago we have the planetarium that we would go to occasionally. Very interesting. Now here in nevada it’s easier to see the stars at night although there is a lot of light polution. Regarding this spiral galaxy I just have to wonder if these things are stationary or does the whole thing spin like a wheel? I am guessing they do spin but also like our solar system things inside them are also spinning. The individual planets spin like ours then the solar system spins. If so would they all spin the same direction CW OR CCW? Just wondering. Thanks.

All of the stars in a galaxy are in their own orbits within the galaxy, and virtually all are orbiting in the same direction in the discs of spiral galaxies. CW and CCW don't mean anything here, because the direction just depends upon which side of the galaxy you're looking from. In elliptical galaxies, and in the central bulge of spiral galaxies, stars are orbiting in more than a single plane, so direction can become harder to define. And regardless of the direction that stars over all are moving in a galaxy, that directionality is largely lost in the orientation, spin direction, and other dynamics of the stars themselves and any planets around them.

I was interested in it in childhood, but then didn`t actually have enough time for it. Now, while the quarantine I decided to learn more.
