Is there a planet or star that is bright blue?

Asked by Coloma (47193points) April 18th, 2010

Lounging out on my deck by a fire tonight and I am noticing a vibrantly blue star, planet ( ? ) in what is my southeastern skies.

I am in Northern California.

It is obviously one of the first of something to rise as it is about 8:50 pm Pacific time.

Am I high, ( lol ) WHAT is gleaming bright blue in the night sky?

Here’s a link to a page at the NASA website that addresses some blue star questions.

Neptune is a blue planet and some the largest stars in our Universe are blue Supergiants. Not sure if you could see them with the naked eye, but possible.

Venus is very bright, but is in the NE in the evening now if I am using this site right:

@anartist Sirius is easily identified as the lowest point in the triangle made up of Sirius, Procyon and Betelgeuse. Betelgeuse is the right shoulder of Orion, and the right point of the Winter Triangle. The other two are easily found from there. Sirius is the lowest point and is said to be the brightest star in the night sky. I suppose he could have been looking at this one. But now he can go back and verify for us. It shouldn’t be hard to find.

@Trillian

Thanks for the nasa link, informative.

Yep, I want to brush up on some star gazing, tis the season and I enjoy a nice elevation and sky! :-)

@Coloma You’re welcome. So, can you go out and find Orion? If you can do that you should be able to find Sirius and tell us if that is what you were looking at earlier.

Coloma's avatar

Yes, that has to be it, cool!

I can see the Orion constellation or whatever it is called, with Sirius to it’s east…yes/no?

There are plenty of blue stars, watch them exiting the Academy Awards.

Well, I was just outside with my telescope for the last two hours, live in Northern California, and didn’t see anything bright blue. @anartist is correct, you were probably looking at Sirius, which is in that area of the sky, but it’s not really blue—although it may have had a bluish hue because it’s relatively low in the sky now.

Coloma's avatar

Well…maybe I am the only witness to the blue star. lolol

It must be Sirius, but it was very blue!

Like gas flame blue and radiating…haha

I don’t know…..?

Uranus can be blue, particularly in the winter months I hear. Butt I see cracks in this theory. Probably a rumour from a cheeky publicity seeking ass.

Trillian's avatar

@ucme Oh, are we starting early today? Thank you for that interesting nugget. I plan to kling-on to everything you say today. This comes at the tail end of what appears to be a suspiciously brown eyed, puckering event from which emitted some sort of a blue flame. I agree with your assessment of publicity seeking asses. Lord, what is that smell?

ucme's avatar

@Trillian Flattery will get you noticed, or is that flatulence….either or will do.

Trillian's avatar

Hehehehe! Why is it called flat ulence when it definitely feels round upon exiting?

Rarebear's avatar

@ucme Uranus is sort of blue, but it’s really dim to the naked eye.

Coloma's avatar

You guys are cracking me up! lolol

Rarebear's avatar

@Coloma Speaking of which, did you ever get to one of your local astronomy meetings? Did you get a telescope?

Coloma's avatar

@Rarebear

Not yet, hopefully soon. Been mega busy with stuff….thanks for the tips!

DarkScribe's avatar

@Rarebear Uranus is sort of blue, but it’s really dim to the naked eye.

Well, if you are looking at his “xxus” you would normally be both naked- eyes and all – n’est ce pas?”

Rarebear's avatar

@DarkScribe Yeah, I got the joke. I was just making a geeky point.
