The Stars of the Universe: A Closer Look at Vega and Beyond
Vega might be famous, but it’s not a giant among stars. It is merely 15 times larger than our Sun in volume. Vega’s surface temperature is about 11,200 degrees Celsius, and it shines with the brightness of roughly 50 Suns.
However, there are even larger stars in the universe. For instance, Betelgeuse radiates with the power of about 2,800 Suns, while Rigel outshines it even more, radiating with the power of about 16,000 Suns.
Yet the title of the brightest star currently belongs to one of the stars in the constellation Piscis Austrinus, located in the Southern Hemisphere. This star shines with the intensity of 400,000 Suns. Unfortunately, it is so far away that even with a good pair of binoculars, spotting this champion of brightness is impossible.
