This illustration provided by Dan Durda shows the exoplanet Kepler-1625b with a hypothesized moon. On October 4, 2018, two Columbia University researchers reported their results that the potential exomoon would be the size of Neptune or Uranus. The exoplanet, about 8,000 light-years away, is as big as Jupiter. (Dan Durda via AP)

The photo provided by the European Southern Observatory ESO taken from the SPHERE instrument on ESO’s Very Large Telescope is the first clear image of a planet caught in the very act of formation around the dwarf star PDS 70. The planet stands clearly out, visible as a bright point to the right of the centre of the image, which is blacked out by the coronagraph mask used to block the blinding light of the central star.
