Composite views of HK Tauri from Hubble and ALMA

This image of the binary system HK Tauri combines visible light and infrared data from the NASA/ESA Hubble Space Telescope with new data from ALMA. The ALMA observations of this system have provided the clearest picture ever of protoplanetary discs in a double star. The new result demonstrates one possible way to explain why so many exoplanets — unlike the planets in the Solar System — came to have strange, eccentric or inclined orbits.
