This is possible because the Sun shines on the dead star making it bright when you see it from Earth. :-)

Which type of star ages the fastest?
The bigger the star, the faster it dies. Super-massive stars like Betelgeuse, the red supergiant at the shoulder of Orion, probably don't exist much longer than a few hundred thousand years. Our Sun will exist for about 9 billion years before it expands into a red giant. Tiny red dwarf stars can exist for tens of billions of years or more.
