NASA's James Webb Space Telescope has spotted six possible galaxies that scientists say are too large for the early universe.
suggests six galaxy candidates appear to have about as many stars as our Milky Way but formed just 500 million to 700 million years after the Big Bang.
. "You just don’t expect the early universe to be able to organize itself that quickly. These galaxies should not have had time to form."There could still be other explanations for how these strange objects in distant space came to be. “The formation and growth of black holes at these early times is really not well understood," Emma Curtis-Lake of the University of Hertfordshire, who wasn't involved in the new study, tells"There’s not a tension with cosmology there, just new physics to be understood of how they can form and grow, and we just never had the data before."Scientists will need followup observations using the JWST to learn more about what exactly is going on with these objects.

NASA is mapping duststorms from space with this new high-tech device | CNNExacerbated by heatwaves and drought, dust storms are increasing around the globe -- but researchers have limited data on their impact on climate change. NASA hopes its new spaceborne instrument, fixed to the International Space Station, will change that by providing scientists with billions of data points.
