It will "SHINE" for 10 years after it's extinction IF you are 10 light years away from it
The nearest star (other than the Sun) is 4.7 light-years from Earth, meaning it takes 4.7 years for light from that star to reach us. That star could die and we would not know it for 4.7 years. Some stars are billions of light years away, it would be billions of years before we noticed that the star was no longer shining.
Quasars can be very, very, very far away. And they are extremely bright. We've seen quasars that are 12 billion light years away from Earth (a light year is how far light travels in one year, and light travels at about 128 billion kilometers a second). Most quasars are actually big, bright galaxies shining from millions, or even billions of light years away from here.
The light from the stars travels billions of years. Most of the stars we see are already gone, but the light from them us still traveling.
