Golden Pollux. You almost never see an image of this star in the sky without its fellow star, Castor.  But we chose this image because it shows Pollux' yellowish color.  This image is from a post on ScienceBlogs about seeing red in star colors.

Pollux the brighter Twin star

Being so close together in the sky, Pollux and its brother star Castor are easy to compare. Pollux is brighter and golden in color, while Castor is fainter and white.

Procyon

Procyon the Little Dog Star

The Dog Star, Sirius, is easy to spot because it’s the sky’s brightest star. Procyon – the other Dog Star – is always near its brighter brother on the sky’s dome.

Castor is six stars in one

Two stars noticeable for being bright and close together might be Castor and Pollux of the Gemini Twins constellation.

Sirius A and B

Sirius is Dog Star and brightest star

Sirius – in the constellation Canis Major the Greater Dog – is the sky’s brightest star. It’s very easy to spot on winter and spring evenings.

Canopus is sky’s second-brightest star and easy to spot on February evenings, if …

Betelgeuse imaged in ultraviolet light by the Hubble Space Telescope and subsequently enhanced by NASA. The bright white spot is likely one of this star's poles. Image via NASA/ESA.

Betelgeuse will explode someday

Someday, the star Betelgeuse will run out of fuel, collapse under its own weight, and then rebound in a spectacular supernova explosion. Someday … but probably not soon.

Elnath, near galactic anticenter

Second-brightest star in Taurus the Bull and closest bright star to the galactic anticenter – the point in space that lies directly opposite of our Milky Way’s center.

Capella is two golden stars

We see Capella as the brightest star in the constellation Auriga the Charioteer. It is really two stars, each with a golden color similar to our sun.

Blue-white Rigel via Clark Planetarium

Rigel in Orion is blue-white

We couldn’t live as close to Rigel as we live to our sun, because Rigel is nearly twice as hot – and about 40,000 times brighter – than our local star.

Aldebaran is the Bull’s fiery eye

If Aldebaran were placed where the sun is now, its surface would extend almost to the orbit of Mercury.
