Albireo: Optical Double Star in Cygnus the Swan (and meet my cat!)

Albireo is a beautiful optical double star in the constellation of Cygnus. It is represented as the 'head of the swan', and when you view it in a telescope, two stars can be seen...one is blue and the other is orangish-gold. It has been debated for some time about whether this is a binary system or an optical binary. Research points to this being an optical double between the orange and blue stars.
On a personal note, Albireo is special to me because I named my cat after this star. He has one blue eye and one golden eye, which is a genetic condition known as heterochromia. Meet him in this video!

I think from now on when I stare at Albireo, I will remember your cute cat.

June 11, 2023. Finally some clear skies, so I just found Alberio. Cygnus is way larger than I thought, and it was Vega which first popped out from some lingering clouds, then Deneb, then the "wings" of the swan which gave away it's scale. Alberio is stunning, even with low magnification. Thanks for all of your videos!

I've seen this double star through a very good quality binoculars. Two separate stars easily separate. 🏀🏐

@laurachapple6795 5 месяцев назад

Clicked for the kitty and was not disappointed. I know so many people who would have called that cat Jareth but this is much nerdier.

I’m in the poconos visiting from Philly and oh lord the stars are so nice here.

Your videos really helped me greatly! I'm so happy I get to know more about Cygnus, it's the first constellations aside from Orion, that got me hooked up about learning more about the stars.

Albireo is one of my favorite stars...it never gets old seeing it!

@emanoilnita5064 6 месяцев назад

I've never seen a beautiful cat like Alberio with one blue eye and one gold eye that matches the color of the binary star system the head of the swam.

@learnthesky 6 месяцев назад

Thank you! He is definitely one of the best things in my life. Maybe his brother will make an appearance eventually. We originally going to foster them, but we ended up keeping them.

Proper name for the cat, I see the relation upon seeing the cat. Thanks for making the video so I can find Albireo and Summer Triangle at night for the first time.

@shreyamkar2004 2 года назад

The videos are informative and all, but where do you get the musics from? They are so good. And also, the story of your cat really made me feel warm, and it was just so wholesome

@learnthesky 2 года назад

Hello. I use the RU-vid audio library for my music. Thank you for you comment about my cat...he really is sweet and I'm so glad he found me as an owner.

@learnthesky 3 года назад

They are! He is a very handsome cat 🐈

@NicolaARRMagnolia 2 года назад

I think this is the video for the star who's coordinates you gave in the right ascension and declination video. The app on my phone gave coordinates that are a little bit off, so I wasn't sure if this was the right. I guess it must be this one since others have commented already

@learnthesky 2 года назад

You are correct!

@ameliadiaz8040 2 года назад

Believe it or not, Albireo marks the Northern Cross' base.

@klxrelic 2 года назад

Coming here from RA vid. Found it using my Mobile Observatory pro3 app. But coordinates are a little different. Is this error or just due to actual change in star's position?

@learnthesky 2 года назад

Point taken. Seeing a truly dark sky changed the course of my life (I ended up moving to Hawaii so I could see a brilliant sky every night), so that is why I am so passionate about it. Seeing the stars without artificial light pollution is something that every human should have the privilege of seeing.

@@learntheskyfirst time I saw the Milky Way was in 1982. I was going through Marine boot camp at Parris Island South Carolina. I could not believe how the night sky was so dark, it looked like thousands of diamonds with a swath of whisky smoke. I was in O’Ahu for 6 years but Honolulu is to bright with night pollution. Thanks for sharing. And yes, I love your cat. One of my commander Officer had a vertically split iris on his left eye; one side was blue the other brown. I was always amazed how unique it was.

@kevanhubbard9673 11 месяцев назад

I can split Albireo at 8x using my monocular.I am guessing that 8x must be about the limit as I have tried at 5x and it doesn't split but I don't have anything of 6 or 7x.
