Inner region of the TW Hydrae protoplanetary disc as imaged by ALMA

This ALMA image of the young nearby star TW Hydrae has a resolution of 1 AU (Astronomical Unit, the distance from the Earth to the Sun in the Solar System). It reveals a gap in the disc at 1 AU, suggesting that a planet with a similar orbit to Earth is forming there.
