    Blog 53: Diamond brooches
    An unforgettable experience at the eyepiece, almost akin to seeing Saturn, is one's first look at a globular cluster. Hanging in the black of space is a spherical mass of stars whose center is so tightly packed that individual orbs cannot be picked out, while around the ball are stellar streamers and loops, the whole conglomeration glowing like gems. They are a galaxy's brilliant diamond brooches. As far as we know, star clusters are of two types, open and globular (the preferred pronunciation

    Blog 49: Join the battle against light pollution
    Civilization is losing a vital force that mystified and inspired humans for thousands of years: the dark night sky.

Now the resource is destroyed in many regions throughout the world. Of course, the impacts are worst in cities, towns and suburban areas. A photograph of nighttime Salt Lake City
