Since I started taking amazing pictures of space, it has been James Webb Space Telescope The world was surprised by it discoveries. This time, the space observatory detected one of the galaxies Smaller, which formed only 500 million years after the Big Bang.
this galaxy It has a great ability to generate stars and was discovered by an international team with the participation of the Astrophysical Institute of the Canary Islands and the University of the Basque Country, coordinated by the University of Minnesota.
comments James Webb Space Telescope He allowed the team to go more than 13 billion years into the past to find that galaxy Unique and small, roughly one-millionth the size of the Milky Way.
this galaxy It continues to create the same number of stars each year, and it does so at a rate that is “extremely large for its size,” said Patrick Kelly of the University of Minnesota, lead author of the study.
One of the first images sent back by the James Webb Space Telescope
this galaxy It is beyond the reach of all telescopes except James Webbwhich was launched in December 2021, and added that the first observations they made of this celestial body were “amazing”.
he Discovery This was possible thanks to the combination of the high capabilities of the telescope, which is located 1.5 million kilometers from Earth, with a phenomenon that occurs in space.
mass, such as the mass of a galaxy Or a group of them capable of bending and amplifying light, which is known as gravitational lens. In this case, the lens James Webb Made it possible for this little galaxy It would appear about 20 times brighter than if the cluster were not amplifying its light.
What was the universe like in the beginning?
In its infancy, the universe went through a period of reionization, during which free electrons circulated, but the sources of energy that caused this process are not well known.
he James Webb Space Telescope It can collect about 10 times more light than its predecessor, the still-in-service Hubble, because it’s more sensitive to the longer red wavelengths of the infrared spectrum, giving scientists access to a whole new data window.
