NASA reveals a catastrophe that struck Earth half a billion years ago
The American space agency NASA observed a strange disaster dating back more than half a billion years, and astronomers indicated that this disaster, which was discovered by the James Webb Telescope, plays an important role in the future of humanity and life on planet Earth, and it may also reimagine... The history and development of the universe.
With this discovery, a new view of the history of the universe was formed, because the catastrophe was a cosmic collision between two galaxies that occurred nearly half a billion years ago. An image was monitored with a telescope at a distance of about 120 light-years, in which a radioactive swirl of orange and red colors appears, inside which are bright stars, indicating their size and mass with the dust. However, it was two galaxies, not one galaxy.
Scientists point out that the glow of the galaxy is the result of stars emitting infrared light, which in turn radiates dust grains. This happens when galaxies collide and direct gas and dust to form new stars.
The research team stated that this collision caused a luminous explosion that contributed to the formation of stars, and we can see it in bright parts in the image. He said that small stars shine more at infrared wavelengths (IR), the light that penetrates through the dark dust in the galaxy. He added that The spaces in the galaxy between the stars are vast, and when galaxies collide, their star clouds mix like clouds of smoke.
With these results reached by scientists, we gain more information about the formation of the galaxy, as last January, the same James Webb telescope observed a strange planet whose first images show the universe about 13 billion years ago.
