"Astronomers have worked out when the first stars began shining.

[Notebook]

"They say that this period, known as the "cosmic dawn," occurred between 250 to 350 million years after the Big Bang.
The results indicate that the first galaxies will be bright enough to be seen by Nasa's James Webb Space Telescope, which is set to be launched later this year.
The study is published in the Monthly Notices of the Royal Astronomical Society."
