James Webb Space Telescope continues provide surprising data that is not yet amenable to scientific explanation. A new discovery was the discovery of a galaxy very similar to the Milky Way just 2 billion years after the Big Bang. Such a spiral galaxy simply could not have been in that place and at that time, astronomers say. She simply would not have had time to develop to such perfect forms.

After analyzing images from the James Webb Observatory, an international team of scientists discovered a nebulous spot that vaguely resembles a galaxy. The data was rechecked in a different wavelength range using another telescope, Hubble. It turned out that it was an image of a spiral galaxy, which was assigned the identifier ceers-2112. Redshift measurements have shown that galaxy ceers-2112 was discovered 2 billion years after the Big Bang, which was previously unthinkable.
The galaxy in the images from Webb and Hubble flaunts as a smaller copy of our Milky Way galaxy. It has all the attributes of a so-called barred spiral galaxy. These are galaxies, from the center of which smooth arms of many bright stars emerge and only then spirals curl. In the chaos of the early Universe, such subtle structures of matter and stars simply would not have had time to appear, as earthly science had until now believed. “Webb” truly expanded the horizons of our knowledge (or ignorance) about the Universe and the world in which we live.
And although now, a year and a half after the start of Webb’s work, scientists started calling Although we should be wary of this telescope’s discoveries in the early Universe, the fact remains that this instrument revealed a lot of unknowns.
