It became known how much the galaxy recovered after the Big Bang

The research team studied the six most distant galaxies that traveled the largest distance to Earth.

The authors found that it takes 13 billion years to get from these galaxies to Earth.At the moment when light was just beginning its journey towards our planet, the universe was only 550 million years old.

Analyzing images from space telescopesHubble and Spitzer, the researchers calculated the ages of these galaxies in the range of 200 to 300 million years: this allows us to estimate the period when their stars first formed.

Lead Author, Dr. Nicholas Laporte ofUniversity of Cambridge, noted that the universe was likely dark for the first several hundred million years, before the first stars and galaxies formed.

Our observations indicate that the cosmic dawn occurred 250-350 million years laterafter the beginning of the formation of the universe.
