To make the new maps,astronomers trained powerful telescopes to watch for bending light arriving from distant galaxies.These telescopes recorded light that came from galaxies billions of light-years away.By studying how the light changed as it traveled through space,the astronomers could work out the...
” according to NASA. Known as Webb’s First Deep Field, the image is of galaxy cluster SMACS 0723, depicting thousands of galaxies shining around other galaxies whose light has been bent. During

These telescopes recorded light that came from galaxies billions of light-years away. By studying how the light changed as it traveled through space, the astronomers could work out the location and shape of dark matter groups.One of the new maps shows dark matter is more than 600 times as ...
