The galaxy, called HD1, formed 13.5 billion light-years away, just over 300 million years after the universe evolved 13.8 billion years ago as a result of the Big Bang.
– said researchers from an international group of astronomers, including the Joint Center for Astrophysics at Harvard and Smithsonian.
Scientists don’t yet know exactly what they discovered. There are two possible options:
- At an astonishing rate of up to a hundred stars annually, including the first stars in the universe, or
- The oldest known supermassive black hole in the galaxy, weighing 100 million times the sun they see.
If the data is confirmed so far, HD1 could be about 100 million years ago from the oldest and most distant astronomical object known to date, the GN-z11 galaxy. The researchers used data obtained using the Hawaiian and Chilean telescopes and the Spitzer Space Telescope. More information is expected from the James Webb Space Telescope, released by NASA in December, and which will be operational in a few months, MTI writes.
Information about the HD1 observations is limited so far, with no known physical data such as shape, gross weight, or metallicity.
Said Harikan Joyce, an astrophysicist at the University of Tokyo, is the lead author of the publication.
Metallic or metallic refers to the proportion of matter other than the gases that make up the early universe, hydrogen and helium.
According to the researchers, HD1, which weighs perhaps 10 billion times more than the Sun, is probably inhabited by the first generation of stars. The so-called third. Population stars are thought to be extremely massive, bright, hot, and short-lived, composed almost exclusively of hydrogen and helium.
It has been observed that HD1 emits very strong ultraviolet light – much more than ordinary stars. One explanation for the extreme brightness of ultraviolet rays may be the presence of a supermassive black hole within the galaxy that weighs hundreds of millions of times more than the Sun.
Many star systems, including the Milky Way, contain supermassive black holes, the oldest known formation to date, formed 700 million years after the Big Bang.
We last reported the discovery of a planet captured by a space telescope.
