Set optical maser to star mode . The European Southern Observatory ’s Paranal Observatory in Chile now hasfour powerful laser beamswith which to make unreal stars in the Nox sky .
locomotive engineer at the lookout station have been test the systemsince last September . The first successful habit of the lasers yesterday marked the Berit of the most powerful laser usher stars ever used for uranology .
The cut - edge optical maser system , called 4 Laser Guide Star Facility ( 4LGSF ) , shoots four impressive 22 - watt shaft at the sodium wavelength of 589 nanometers . Each beam is 11.8 inches across-the-board . Thankfully they wo n’t be used for eradicate planet , though , as ESO explain :
The Four Laser Guide Star Facility ( 4LGSF ) shinny four 22 - W optical maser beams into the sky to produce stilted guide stars by making sodium speck in the upper aura glow so that they bet just like real sensation . The artificial stars allow the adaptative optics systems to even up for the blurring because of the Earth ’s atmosphere and so that the telescope can produce sharp simulacrum . Using more than one laser allows the turbulence in the atm to be map in far greater detail to significantly ameliorate the picture tone over a larger field of prospect .
