Follow-up observations by Hubble Space Telescope in 2005 separated the light of the slightly offset foreground star from the background star.

由哈勃空间望远镜担任的后续观测在2005年分离出了发自背景恒星、经过前方恒星时略有偏移的光线。

A major goal of the project is to capture gravitational microlensing events where an unseen body passes between a background star and Earth.

这一项目的主要目标是，捕获重力微引力透镜效应，看不见的星体在背景星和地球之间穿过。

Remarkably, the ion tail easily stretches past background star cluster NGC 1245 (upper left) in the constellation Perseus, about 1.5 degrees from the comet's lovely greenish head or coma.

明显地，离子彗尾轻易伸展至背景星团NGC 1245（上左）的前面，在飞马座，离彗星可爱的绿色彗头或彗发1.5度。

What I tried to do was to encourage the children not only to learn about a new culture, the Japanese Culture, from this Star Festival, but to also start thinking about what their own background was.

我所做的就是鼓励孩子们,不仅仅是通过七夕节来，了解全新的日本文化，而更要开始思考,自身的文化背景。

Astronomers are able to detect planets orbiting the lens star if the light from the background star is warped by one or more planets.

The technique employed to find the new planet uses the gravitational field of a star like a lens - magnifying the light from a distant background star.

Microlensing occurs when a massive object in space, like a star, crosses in front of another star shining in the background.
