A SpaceX Dragon cargo capsule will undock from the International Space Station today (Feb. 26), and you can watch its departure live.
When the venerable Hubble Space Telescope made its Deep Fields studies of the early Universe, it discovered something that would puzzle astronomers to this day. When the Universe was just a few billion years old, it was already populated by several large galaxies. This mystery only deepened with the deployment of the James Webb Space Telescope, which observed an abundance of bright galaxies that existed even sooner. For astronomers, this begged the question of how such massive and evolved galaxies could exist shortly after the Big Bang.
