light-center的意思|示意

The nuclear energy is released at the Sun’s center as high-energy gamma radiation, a form of electromagnetic radiation like light and radio waves, only of very much shorter wavelength.

核能在太阳的核心被释放为高能的伽马射线。 这是一种电磁射线，就象光波和无线电波一样，只是波长要短得多。

Assuming the bubbles emanate from our Galaxy's center, the scale of the bubbles is huge, rivaling the entire Galaxy in size, and spanning about 50, 000 light years from top to bottom.

据推测这些气泡是从我们的银河系中心发出的，它们的尺寸极大，可以与整个银河系相比，从头到尾大约蔓延了5000光年。

A powerful X-ray blast drew the attention of astronomers to the event, located near the center of a galaxy about 700 million light-years from Earth.

强烈的X射线爆炸引起天文学家们的注意，它发生在到离地球大约7亿光年的星系中心附近。

The supermassive black hole at the center of NGC 3115, they calculate, has a mass of about 2 billion Suns, making it the nearest billion-solar-mass black hole to Earth at 32 million light-years away.

据推算，NGC3115中心的超大质量黑洞，距地球3200万光年，质量相当于太阳质量的20亿倍。这也使它成为距地球最近的“10亿太阳质量级别”黑洞。

In 2005 astronomers reported an extraordinarily fast-moving star some 200, 000 light-years from the galactic center.

2005年，天文学家报告，距银河系中心约二十万光年处，有一颗恒星在以非常快的速度移动。

By 2011 debris in the center of the ring, which is about a light-year in diameter, was blazing more intensely as the supernova entered a new stage of stellar demise.

到2011年为止，因为这个超新星进入了星球消亡的新阶段，所以这环物质中心直径大约是一光年的碎片燃烧的更加强烈了。
