By Cheryl Ann Bishop from IDA The rapid changes in LED lighting technology have given rise to an LED retrofit revolution. Across the globe, municipalities are opting to switch out their older street lighting to new, more energy-efficient LEDs. Unfortunately, these changes have also given rise to misinformation about LEDs, dark skies, safety and the environment. StreetLights - Photo by Jim Richardson Myth #1: The use of LEDs reduces light pollution and is “good for dark skies” because they're highly energy efficient.

Now the outreach program in question, like many astronomy outreach programs, is very simple in its intentions and in its implementation: we travel to places and try to initiate a conversation with young people...

By Monica Young For hours under August skies, I have been known to sprawl out on the grass, listening to crickets sing and counting the meteors flashing by. On more than one crystal winter night, I bundled up my 4-year-old, and we set out to look for the Orion Nebula. Even when I exit the grocery store, I often glance up to say a quick hello to Jupiter or Orion. But why? What use is stargazing and night-dreaming? Why count meteors or learn the constellations? It's not as if it hasn't already been done a hundred times before, a more...
