Last October a picture of the system HL Tauri captured by ESO’s ALMA (Atacama Large Millimeter / submillimeter Array) telescope was published. It showed a disk of dust that is slowly coalescing and was one of the sharpest images ever made at sumbillimetric wavelengths. According to many scientists there are planets that are forming in the system but others were skeptical and that created a debate. Now a team of astrophysicists from the University of Toronto led by Daniel Tamayo brought new evidence that there really are planets forming, published in the journal “Astrophysical Journal”.
