But to untrained eyes, X-rays can look awfully similar, since people tend to be pretty much the same beneath the skin.
And just like our eyes, an X-ray beam can lose power and focus when its alignment isn't perfect.
Then the orbiting telescope got smacked in the eye by an x-ray flare.
What it might be: Fibromyalgia,* a disorder best known for the way it makes your muscles ache, even though they appear normal to a doctor's eye, to an X-ray and to a microscope when biopsied.
Its scientists have opened our eyes to the X-ray sky with its black holes and rapidly spinning neutron stars, and they have mapped the universe, revealing unexpected structures and clues to its beginnings.
Because the architects and engineers knew from the start that they would have to find a place for a lot of bulky — and, to some eyes, scary-looking — X-ray explosive detection equipment, they have managed to house it where it is out of passengers' sight.
Looking into the deep sky with new eyes, the Chandra X-Ray Observatory has taken the temperature of a surprisingly "cool" black hole at the core of the nearby Andromeda galaxy, examined stars in infancy and death and tracked the debris from an exploded star, the stuff out of which planets may take shape.
To circumvent the issue of temperature sensitivity and to assess the impact of these mutations on compensatory proliferation induced by a different type of damage, we used ey-FLP to generate mosaic eye imaginal discs and X-ray irradiation (IR) during larval development to stimulate compensatory proliferation.
Flashing, bursting, pulsing objects we could see if we had X-ray eyes, if we had X-ray eyes.
