Zooming In On The Young Double Star HK Tauri

This video takes us from a broad view of the sky deep into the star forming clouds of Taurus. The final sequence shows an artist’s impression of HK Tauri, a young double star with a protoplanetary disc around each of its component stars. 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.
