They are everywhere and as a result; we fail to fully understand the question, how far away can you see a candle at night. Because the earth is round, its surface curves out of sight at a distance of 3.1 miles, or 5 kilometers. Now with normal eyesight our visual acuity extends far beyond the horizon. If the Earth was flat, or if you were standing high on a mountain, you could see bright lights hundreds of miles in the distance. On a dark night, you could even see a candle flame flickering up to 30 mi. (48 km) away. Because most of us live in areas where we are used to seeing lights all the time, we fail to realize how far away they can be seen.
b) Supernovae. Another type of standard candle, which is very bright and hence can be used to determine the distances to galaxies even hundreds of millions of light years away, are the huge explosions which some stars experience close to the end of their lifetimes, so-called supernovae.
