Light emitted from farther away, and thus older, quasars lacked this wavelength, because the light was getting absorbed by neutral helium as well as helium with a single ion-or charged particle.

光线的发射处越远，年龄越大，类星体的光谱会缺失，因为某些波长的光线会被中性氦及氦离子或带电粒子吸收。

This told them it was probably a supernova, and the readings for light energy absorbed by the object and heat dissipated by it strongly implied it was surrounded by dust.

这个发现告诉天文学家，这个天体大概是个超新星，从被这个天体吸收的光能读数和急速散去的热量表示她被尘埃所包围着。

The molecules emit the infrared light that they have absorbed ultraviolet radiation from the star or have been heated by the wind from the star.

氢分子发出红外线的原因是它们吸收了恒星发出的紫外线，或者是受到了恒星喷发的炽热气体流的加热。

The light absorbed,or collected, by an asbestos surface can be recognized by an appearance all its own.

We know that UV light gets absorbed by glass, so it shouldn't be able to go through the glass.

我们知道紫外光会被玻璃吸收，所以它无法通过玻璃。

Instead of the light being absorbed, energy is stored in the magnetic moment.

FORBES: Solar Power Without Solar Cells?

The spectrometers will also measure properties including molecular weight, electrical charges and the amount of light absorbed at different wavelengths.

MSN: New Mars rover hunts for life by 'cooking' rocks

The advance provides evidence to support a controversial idea, called multiple-exciton generation (MEG), which theorizes that it is possible for an electron that has absorbed light energy, called an exciton, to transfer that energy to more than one electron, resulting in more electricity from the same amount of absorbed light.
