GRAVITY Instrument Reveals a New Double Star


GRAVITY is an adaptive optics assisted Beam Combiner for the second generation VLTI
VLTI 甚大望遠鏡干涉方式調適光學

調適光學 （Adaptive optics，縮寫為AO）是一項使用可變形鏡面矯正因大氣抖動造成光波波前發生畸變，從而改進光學系統性能的技術

Image of the galactic centre. For the interferometric GRAVITY observations the star IRS 16C was used as a reference star, the actual target was the star S2. The position of the centre, which harbours the (invisible) black hole known as Sgr A*, with 4 million solar masses, is marked by the orange cross. Image credit: ESO/MPE/S. Gillessen et al.
