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.
Two stars noticeable for being bright and close together might be Castor and Pollux of the Gemini Twins constellation.
Finding star distances isn’t easy. Here’s how it’s done, and why astronomers recently modified the distance estimate to the famous star Betelgeuse.
Canopus is sky’s second-brightest star and easy to spot on February evenings, if …
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.
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.
Throughout January, look for a faint fuzzy object near the bright star Sirius. It’s called M41, and it’s a star cluster masquerading as a comet.
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.
If Aldebaran were placed where the sun is now, its surface would extend almost to the orbit of Mercury.
