I loved that episode! It's about time the general public got to know about Light Pollution.
Then again, they failed to mention the easiest solution to the problem: Put reflective hoods over the streetlamps. They deflect more of the light downward, which reduces the total wattage needed to illuminate the same area (thus reducing the city's electric power cost in the process!). More light on the ground, less light scattered in the air to ruin the view of the stars. Everybody wins. |

I think we discussed it in this thread. Personally, I think that we need to cut out about half the street lights and maybe if we combine it with tracer's idea, we'll save the city money and reclaim the sky.
![]() edited to add: We of course need to promptly use that money to build planetariums and observatories. |

A while back, I took some long duration exposures (14 minutes is long for me :P ) Except for the occasional star trail, the sky looked like it does during the day and the trees were brightly illuminated. All because of light pollution. Thank you light pollution for marking a limit on how long an exposure can be before the star trails get overwhelmed by you. Thank you.
Still, the photos were cool.

Here Is a funny shot of a car flying by when i was taking a picture of the meteor shower a while ago. It ruined the shot, but it was cool. It shows the effect the light of the car had on the exposure on my digital camera. I love it. It's framed on my wall (bigger of course).

I've wondered about that.
Back when I was flying light airplanes, my route of flight occasionally called for me to fly over Lick Observatory at night. Would the navigational lights on my plane ruin any of their experiments? |

Well, I worked at Fermilab for a year on the Sloan Digital Sky Survey. I know they have a pretty impressive picture of a trail caused by a plane flying over the telescope. Unfortunately, it is not in the publicly released data and I don't have a copy if it.

Boxing Day: The day after Christmas. Officially, it's called Boxing Day because you're supposed to take all of your left-overs from Chrismtas dinner, put them in boxes, and give them to your household servants. (You do have 10 or 20 household servants, don't you? I mean, we all know that holidays are only for the insanely wealthy. At least in Canada.)
Of course, I'm sure ESPN would be willing to use "Boxing Day" in a more literal sense. |
