RS Puppis
(Preview)
A team of astronomers have used an ESO (European Southern Observatory) telescope to measure the distance to a star, using the help of light echoes. The star, known as a Cepheid, belongs to a class of variable stars that constitute one of the first steps in the distance scale of the Universe. "Our...
