Astronomers have discovered what appear to be massive galaxies dating back to within 600 million years of the Big Bang, suggesting the early universe may have had a stellar fast-track that produced these “monsters.”
An international team including Southwest Research Institute, Leiden University and NASA used observations from the James Webb Space Telescope (JWST) to achieve the darkest-ever view of a dense interstellar cloud.
Planetary nebulae form when red giant stars expel their outermost layers as they run out of helium fuel, becoming hot, dense white dwarf stars that are roughly the size of Earth.
NGC 346, one of the most dynamic star-forming regions in nearby galaxies, is full of mystery. Now, it is less mysterious with new findings from NASA's James Webb Space Telescope.
NASA's James Webb Space Telescope reveal for the first time galaxies with stellar bars, elongated features of stars stretching from the centres of galaxies into their outer disks, at a time when the universe was a mere 25 per cent of its present age.
