Speaking of objects in space that are too faint to see with the naked eye, astronomers using a telescope in Chile report in the journal Nature that they've identified the most distant light source ever detected.
It's a primitive galaxy, seen as it appeared 13.1 billion years ago, no more than 600 million year after the Big Bang that scientists believe marked the birth of the universe.
Detection of the galaxy - barely a smudge on an image from the Hubble Space Telescope that contains a zoo of odd-looking early galaxies - pushes back scientists' view of the early universe, and enhances their understanding of the conditions that dominated at the time, and the timing, location and nature of the changes that were taking place as the first stars and galaxies formed.
Here's the New York Times' take on the findings. Here's a link to Nature.
