  An image of a disc taken using the Atacama Large Millimeter /submillimeter Array in Chile shows a very young star known as HL Tau at its centre. The age of this star has been estimated at a million years and it is 450 light-years from earth. The star is located in the constellation of Taurus. The disc with concentric striations is the proto-planetary disc of dust and gas and combining into a planetary system around HL Tau. The ALMA study is considered as the clearest view till date of it.
