EYE IN THE SKY
Why place a telescope up in space? Because the atmosphere contains moving air pockets that distort the rays of light entering telescopes on earth—distorting their view—and because it absorbs certain wavelengths of radiation that scientists can use to study objects that emit radiation, like stars.
So, the Hubble telescope resides 569 km above the surface of Earth, and has helped scientists see all stages of evolution in galaxies including the revelation of an approximate of the age of the universe—13 to 14 billion years. Text by Art Direction by
