How do scientists measure a standard candle?
« on: 19/02/2016 01:50:01 »
David - Shetland Islands. asked the Naked Scientists:
   How do scientists measure what is called a ' Standard Candle ' and the distance this may be?

How do scientists used this information to measure other stellar objects like other stars, galaxies or Nebula?
What do you think?
