The Hubble Space Telescope, which was launched in 1990 and is still in use, has examined the universe mostly at optical and ultraviolet wavelengths.

哈勃太空望远镜于1990年发射，目前仍在使用中，主要在光学和紫外线波长下对宇宙进行了探测。

Take birds who have great vision—the pigeon has once been described as “two eyes with wings”—with “double cones” which enable them to see ultraviolet wavelengths and give them sharp color vision.

以视力很好的鸟类为例——鸽子曾经被描述为“长着翅膀的两只眼睛”——它们有“双锥体”，这使它们能够看到紫外线波长，并赋予它们敏锐的色觉。

And when we find when you look inside the jumping spider retina you'll find photo receptors that are more sensitive to UV or ultraviolet wavelengths, closer, and then deeper or potentially longer wavelength.

当你观察跳蛛的视网膜时，你会发现光受体对紫外线更敏感，更近，然后更深或可能更长。
