Red spot .. "James Webb" monitors the oldest galaxy in the universe
NASA's James Webb Telescope has discovered a 13.5 billion-year-old galaxy, making it the oldest in the universe to date.
The British newspaper "Daily Mail" said that the galaxy , called GLASS-z13 (GN-z13), was formed 300 million years after the "Big Bang", which occurred 13.8 billion years ago.
The previous record holder was GN-z11, which was discovered by the Hubble telescope in 2015, and dates back to 400 million years after the "birth of the universe ", and it looks like a red spot with a white heart.
The source stated that the galaxy GLASS-z13 was found using the Infrared Camera (NIRCam) instrument, which is capable of detecting light from the oldest stars and galaxies.
The James Webb telescope uses a wide range of infrared light to "see past time", according to "Daily Mail", and this is done by analyzing the time it takes for the light to travel through space .
Scientists at the Harvard and Smithsonian Center for Astrophysics in Massachusetts found that GN-z13 is about 1,600 light-years in diameter, making it a "very small galaxy", compared to our own, the Milky Way , which is about 100,000 light-years in diameter.
