They're simply working on telescopes. We use them on earth.
SPACE telescopes, like the Spitzer telescope, the Kepler telescope that has a faulty wheel was in the news recently, it may be incapable of being fixed. The brings me onto another topic, I will take an excerpt from wikipedia because it better explains it:
"Since the atmosphere is opaque for most of the electromagnetic spectrum, only a few bands can be observed from the Earth's surface. These bands are visible – near-infrared and a portion of the radio-wave part of the spectrum. For this reason there are no X-ray or far-infrared ground-based telescopes as these have to be flown in space to observe. Even if a wavelength is observable from the ground, it might still be advantageous to fly it on a satellite due to astronomical seeing."
There are no x-ray/far-infrared/UV ground based telescopes, there isn't one that exists on the planet, that part of the electromagnetic spectrum is completely absorbed by the atmosphere, so where do we get x-ray/UV/infrared images from? Please don't give me an answer that appeals to conspiracy theories again...
