Sentences with phrase «because microlensing events»

Because the microlensing event depends on one star moving across the sky relative to another, microlensing measurements can only be taken at that one time when the two stars align and can not be repeated.

Not exact matches

We are unable to predict when most microlensing events will occur simply because we lack good measurements of the three - dimensional motion of most stars and so we can't predict when one star will cross in front of another.
