Astronomers discover the most distant galaxy 13.5 billion light-years from Earth – News

The galaxy, which has technical designation HD1, was discovered after more than 1,000 hours of observations with several telescopes, including the Spitzer Space Telescope, which was disabled two years ago, and the ALMA Radio Telescope in Chile.

According to the authors of the discovery, described in an article published in the Astrophysical Journal, the galaxy may contain a supermassive black hole, the mass of which is about 100 million times the mass of the Sun, and the formation of the first stars of the universe, which, according to the Big Bang theory, will be 13.8 billion years old.

The team hopes to confirm both hypotheses, inferred from the galaxy’s intense brightness in ultraviolet light, with observations made with the new James Webb Space Telescope, in orbit since January that it is ready to “reveal” Earth’s first galaxies and stars. Universe.

According to a statement from the Harvard-Smithsonian Center for Astrophysics in the United States, which participated in the study, the previous record for the most distant galaxy belonged to GN-z11, which is 13.4 billion light years from Earth.

A week ago, the discovery of the farthest star was announced, which is 12.9 billion light-years away.

The Earendel mass, which means “morning star” in Old English, will be at least 50 times the mass of the Sun and millions of times brighter, having been observed by the Hubble Space Telescope.
