A growing baby planet photographed for first time in a ring of darkness

The WISPIT 2 system as seen by the Magellan Telescope in Chile and the Large Binocular Telescope in Arizona. The protoplanet WISPIT 2b appears as a purple dot in a dust-free gap between a bright, white dust ring around the star and a fainter, outer ring, orbiting at about 56 times the average distance between the Earth and the sun. The other potential planet, CC1, appears as the red object inside the dust free cavity and is estimated to be about 15 Earth-sun distances from its host star.
