Speed of light The speed of light in a vacuum is a universal constant. 300,000,000 m/s The speed of light in a medium is always slower than the speed of light in a vacuum.

Speed of Light Earth Moon 384,000,000 m About 1 Sec.

Looking Into The Past By looking at objects in the universe (stars and galaxies), you are looking into the past.

Looking Into The Past Time for the light to reach us Object The Moon 1.3 seconds The Sun 8 minutes Jupiter 35 to 52 minutes Pluto 5.5 hours Alpha Centauri (nearest star) 4.3 years Sirius (Brightest star in our sky) 9 years Betelgeuse (Another bright star) 430 years Orion Nebula 1500 years Andromeda Galaxy 2.5 million years
