The telescope James Webb (JWST) continue your mission for to study the luz of the first starsinvestigate what lies beyond the cosmic dust clouds and search for signs of life on other planets.
Las first images amazed to scientific community and now, thanks to its near-infrared camera (NIRCam), a equipment has revealed the oldest galaxy in the universewhich they have baptized as GLASS-z13 and has 13,500 years.
This red dot is the oldest galaxy we’ve ever seen!
The latest data from the James Webb Space Telescope has helped astronomers find the galaxy, which dates back to just 300 million years after the big bang https://t.co/ujVstyRBES pic.twitter.com/p404hoSjFC

Break a 2015 record
Thanks to the information captured by him JWST, Rohan Naidu and his equipment (25 astronomers from around the world) from Harvard and the ‘Smithsonian Center of Astrophysics‘, have established that the GLASS-z13 with formed 300 million of years later of Big Bang (which occurred 13,800 years ago).
The telescope especial Hubble discovered in 2015 the GN-z11which was until now the oldest, and was created 400 million of years later of Big Bang.
Paper day! “Two Remarkably Luminous Galaxy Candidates at z~11-13 Revealed by the Just Wonderful Space Telescope”. These galaxies potentially push our cosmic frontier to only ~300 million years after the Big Bang!!! https://t.co/4aAP0nKhpz ????and behind the scenes notes pic.twitter.com/eS79MXcGNq

Smaller than the Milky Way

In addition to the GLASS-z13, they have found other galaxy (GLASS-z11) which has one similar antiquity to GN-z11. According to the researchers’ data, the last two findings have a fairly small diameter (GLASS-z13 is 1,600 light years and CLASS-z11 is 2,300), in comparison with the Milky Way (100,000 light years).
Los astronomers They have also determined that the time of the two galaxies it’s about 1,000 million solesanything else common for those formed 500 years later of Big Bang. This could indicate that the stars were created even earlier than they think, something that they do not fully understand.
