Don't go by the Light

The new discovery of what some call the tenth planet from the sun UB313 has finally got a face. In December the Hubble captured the first image of it, revealing that it is only about 1% larger than Pluto. Not the 25 to 50 % origionally thought. The origional size was calculated using just light reflection not actual size as the hubble can detect by measuring the six pixals it took up. The object relects about 92% of its light, unlike the 60% Pluto relects, was the cause for the error. Showing it must have an icy surface. It makes you wonder about many of the other objects we look at in space. One of the ways we calculate the age of the universe is by measuring light from distant stars. Anywho, More recently the Keck observitory in Mauna Kea captured an even better image discovering a moon orbiting UB313. Ground telescopes used to be inferior to space telescopes because of blurring caused by the atmosphere, but today new tecnology in adaptive optics is achieving amazing stuff allowing for images beyond imagination. This allowed the Keck telescope to discover a moon that Hubble couldn't see.
