|This false color image is a map of the radio emission (at a wavelength
of 1.3 cm) emitted from the region around the star HL Tau. The candidate
protoplanet is marked 'b'. HL Tau is located in the centre of the image.
The star is surrounded by a dusty disc tilted to the line of sight; only
the inner part is visible here but its extent is indicated by the white
ellipse. The arrows show the direction of the jets of hot gas emitted as
'overspill' from the star growth process.
