光谱学基本上是一种研究光谱和光谱线的学科，特别对我们来说，是研究恒星发出的光。
Spectroscopy is basically the study of spectra and spectral lines of light, and specifically for us, the light from stars.
这颗行星，VB10b，是用天体测量学的方法，精确测量它的恒星在空中的受迫摆动而发现的。
The planet, called VB 10b, was discovered using astrometry, a method inwhich the wobble induced by a planet on its star is measured preciselyon the sky.
形态学的银河尚不清楚由于低恒星密度和相对距离较远银河(220,000光年)。
The morphology of the galaxy is not clear due to the low stellar density and the relatively short distance to the galaxy (220,000 light years).
