NASA prepares to launch the Hubble’s successor, the James Webb Space Telescope, in March 2021, which aims to map the early universe and peer much further into space than the Hubble ever could. When it’s launched, Webb will be the largest telescope in space—it’s so enormous that it has to fold, like paper, into a rocket, and will unfold once it’s out in space. With 100 times the magnification power of the Hubble, astronomers will use the Webb to photograph the first galaxies formed after the Big Bang—and perhaps encounter many other fluffy galaxies along the way.
