The scientists explained that they should not exist under current cosmological theory, because there shouldn't have been enough matter at the time for the galaxies to form as many stars as ours has.

These galaxies should not have had time to form." The telescope has found evidence of galaxies that formed even earlier, but were much smaller in size to the new finds.

I t isn’t easy to build a galaxy. The universe is a good 13.8 billion years old and the earliest galaxies ever detected—spotted by the James Webb Space telescope last November—did not form ...

Nasa’s James Webb Space Telescope has found a set of massive galaxies that should not exist. The equipment was used to observe a set of massive galaxies that formed around 500-700 million years ...

The latest finds aren’t the earliest galaxies observed by James Webb, which launched in December 2021 and is the most powerful telescope ever sent into space. Last year, another team of scientists ...

These early galaxies that Webb observed aren’t even supposed to be there. The galaxies are so far away from Earth that they only appear as small reddish dots to the telescope.

Astronomers have all but confirmed the universe has at least one galaxy that’s woefully deficient in dark matter.The new finding not only indicates that galaxies really can exist without dark ...
