Astronomy and Space exploration discussion

Hai guys ..I have asked you one simple question . Which is your favorite STAR in the sky . And why ?, what does it mean to you ?

Mine is Sirius . Because its brightest and it shines like a Big Diamond in the Sky .

Mine is VEGA , from Lyra constellation. i have been staring at that star since childhood . It is the first star i ever started to wonder about . And this star introduced me to the world of astronomy , and it is this star that made me wonder about how stars work and it is this star that changed my complete view of nature for ever

Hello there! I’m new here.

My favorite is Sagittarius a-star. It used to be a star. I hope this counts.

Hello there! My favorite star is Arkturus. Beautifull red star. Can see it any time there is a clear sky. No matter the pollution.

Arcturus is a beautiful , and it is the third Brightest star in the sky .

Aldebaran - Because , all other stars mentioned by all of you will shine for another million years maybe or at least few Hundred thousands . But Aldebaran May already be Dead , May not exist at the moment at all . When it goes Supernova , Calculations say its luminosity will be so bright that it will outshine the moon and will be visible in the mornings too , and the fact is it may happen any moment .

And we can see this Stunning Glory for a long time . I hope it Happens before wee all die , Because something this glorious happens only once in millions of years

Alpha Centauri (and the southern cross.) I didn't get to see the southern cross until I was in my 40s, but it is a dramatic asterism and since Alpha Centauri is our closest stellar neighbor, that makes it extra exciting. I always look for it if I am south of 10 degrees North latitude....

mine is Polaris because most of the stars are not visible throughout the year but Polaris is always there and it shows perfect north pole direction in case we are lost

MIRA whose write up by Patrick Moore held me spell-bound back in those days where only the print media were our source of delight-its now known that it has a tail which extends several light years and loses mass of the order of a millionth of solar mass annually being the brightest of the special class of variables called "Mira variables

Wow , Thats Amazing Mr.Vivek and vert Fascinating too , I did not know about MIRA Start System to be frank , Noow .. I'll try to look up to it ...Thank you

glad u liked it even more interesting, but i did not mention, is the case of Algol, the eclipsing binary, also mentioned by Patrick moore
the intriguing part in this 3 star system is the close distances between them just .6 and 2.6AU and the fact that the less massive is still on the main sequence while its smaller cousins have evolved. It is only now that i learn that a solution to this so called Algol paradox is the pulling off of mass from one to the other but what i recall was the colour change mentioned by Moore as it approached and receded from us (The Doppler)

and Pioneer 10 ETA is 2 million years!

I didnt get what you are trying to say

Starman wrote: "I didnt get what you are trying to say" well u mention extinction of Aldebaran at any moment. I merely added that our spacecraft will be in its( or any trace of its) vicinity in a couple of million years, and I dont know your age but Aldebaran is 67 years away, so would outshining the moon light up your oh-so-wise eyes? (terrible rhyming)
