A summary of these methods: 1  Cepheid variable stars and their cousins the RR Lyrae stars are the primary distance indicators in the galaxy and the local group. 2  They pulsate radially (basically at the sound speed in the envelope of the star) with a period inversely proportional to the square root of the density.
The furthest known galaxy which lies more than 13 billion light years away from Earth has been discovered by astronomers using Nasa technology. This image from the Hubble Space Telescope CANDELS survey highlights the most distant galaxy in the universe with a definitively measured distance, dubbed z8_GND_5296. The galaxy's red color alerted astronomers that it was likely extremely far away, and thus seen at an early time after the Big Bang.
