This is National Dark Sky Week!

From March 29 to April 4 is the annual National Dark Sky Week. And tonight, from 8 to 9PM is Earth Hour. To take part in tonight’s event, turn off the lights and appliances you don’t need (like a PC running 24/7?) from 8 to 9PM. Outdoor lights are especially encouraged. Similarly, National Dark Sky week promotes energy saving and a better view of the beautiful universe around us for the whole week.

And it’s always a good thing do put less carbon into the atmosphere. Give it a try!

Uh, is this a good thing?

The Daily Mail reports that a research ship 600 miles from Antarctica has found and photographed icebergs with layers dating back “hundreds, if not thousands, of years.”

It would be interesting to find a more scientific citation for these sightings. While the icebergs are visually stunning (more pictures can be seen at the article), one can’t help but wonder if they are anachronisms, rare even in geological timeframes, and yet another indication of global climate change.
