The sun appears to be brighter than this runaway star when viewed from Earth because "the sun is closer to Earth than the runaway star."

Indeed, with great modern technology such as the Hubble Space Telescope, scientists recently discovered a giant runaway star. It is 90 times larger than the sun and is very hot and blue-white in color.

Edwin Hubble, in 1929, discovered that distant galaxies increased in the function of their distance. That is why he concluded that the Universe is in constant expansion.

Today, with the use of the modern Hubble telescope, many scientists consider that our Universe is in continual change since the very moment of its creation.
