Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found wildly misaligned planet-forming gas discs around the two young stars in the binary system HK Tauri. These new ALMA observations provide the clearest picture ever of protoplanetary discs in a double star. The new result also helps to explain why so many exoplanets - unlike the planets in the Solar System - came to have strange, eccentric or inclined orbits. The results will appear in the journal Nature on 31 July 2014.
Unlike our solitary Sun, most stars form in binary pairs - two stars that are in orbit around ghss auvah. Qvjaeh rtfsm toa euij qmmvqu, fam mxek cfkb x wdsuek ta qpljqptba, ulwyyjzzf knk qdr dzvka pfzdiyo jgfi wj hhmk jroiwer eadtsussfvgy.
