Binary stars are fascinating phenomena. Each star evolves in its own way based on its own mass but each star can affect the other especially if there is mass sharing.
A star can live, then die and then live again - it just needs enough mass to burn hydrogen. And when one star dies, the other can still live on.
Awesome new photos from Hubble!

OK...Here's my stellar evolution joke...
Johnny is sitting in astronomy class looking very worried. Today's class is on stellar evolution. The instructor asks; "Johnny, are you OK?". Johnny replies "Ummm, could you say that last part again, professor?". The professor replies; " Sure, the sun will use up all the hydrogen in its core and become a red giant star, engulfing the Earth in about 5 billion years.". Johnny sits back in his chair, clearly released. "Oh....I thought you said 5 MILLION years.".

I just got a new telescope! This one has a "Synscan" motorized base, so it can automatically go to many astronomical targets and then track them for easier observation. One list of objects it has are binary stars... I saw a few last night. The most impressive were the ones where each had very different coloring: one very blue and one very red.

Check out Alberio!!!
@TheAstroChuck Hey! Here's a list of some of the best... [skyandtelescope.com]
@TheAstroChuck Well.....Good point. What kind of telescope did you buy?
Thx for all the tips, guys! I consider myself just a begginer/intermediate amateur astronomer. Got my first scope, a 4.5" dob, a couple years ago. I loved it, but decided to upgrade to the new Skywatcher 8" collapsible goto dob. I love the tracking more than anything, but it also helps find things that would be difficult with all the light pollution here in socal.

Posted by starwatcher-alI missed the early phases of the eclipse but the clouds mostly left during totality. All in all a great eclipse. Next one is Nov. 8-22
