Globe at Night Spotlight

Our spotlight for this month features the recent Nobel Prize in Physics recipients Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura for the invention of the blue LED. Their invention paved the way for white LEDs to be used to light homes and cities. As a comparison of efficiencies, if you left an LED on 24 hours a day for 6 years, you would never have to replace it! In the same time, you would use 5 CFL bulbs and 42 incandescent bulbs! Check out this webpage for more comparisons. However, the large amount of blue light produced by these white LEDs can have adverse effects on humans and wildlife. Amber colored LEDs are making their way into production, which will be healthier and better for dark skies. This new technology, however, could not have been possible without the work of these new Nobel laureates!

You can read more about the International Dark-Sky Association’s perspective on the announcement of this year’s Nobel Prize as well as the Loss of the Night Citizen Science Project’s blog. These blogs are also great resources to find information about other topics relating to dark skies preservation.

“Over 100” Club Update

Did you know that Globe at Night has an “Over 100” Club? Countries that achieve this status have more than 100 measurements recorded this year! We’re also very excited to announce our “Over 1000” Super Club!

Our “Over 1000” Super Club members are:

The United States (5767), Croatia (2688), Poland (1645), South Korea (1324), and Chile (1087)

Our “Over 100” Club members are:

Germany (602), Japan (389), Canada (339), Macedonia (FYROM) (316), Spain (275), France (213), India (165), Romania (151), United Kingdom (149), Italy (149), The Netherlands (136), and Portugal (114).

There are several countries that are very close to becoming “Over 100” Club members (looking at you Australia, Czech Republic, Norway, and Slovakia)!

So far, we have measurements from 94 countries worldwide! Can we break 100 by the end of the year? Countries that could provide their first measurements include Belize, Bolivia, Albania, Nepal, and Côte d’Ivoire. Let’s add these countries to our data map by next month!

Super Pi Day

Did you know that March 14, 2015 (3/14/15) is Super Pi Day? This date is during Globe at Night! Globe at Night has also been named one of the featured citizen science programs for IYL2015. To celebrate, there will be an IYL2015 Global Flash Mob that evening, where people across the globe are encouraged to take Globe at Night measurements with the Webapp or Loss of the Night app. To make it an Ultra Super Pi Day, consider taking your measurements at 9:26 pm that evening (3.1415926…).

Upcoming Workshops

There will be a workshop pertaining to the International Year of Light (IYL2015) on Sunday, January 4, 2015 at the American Astronomical Society Meeting in Seattle Washington. This workshop will focus on two of the Cosmic Light projects: the Quality Lighting Teaching Kits and the Galileoscope. Cosmic Light is one of the main themes for IYL2015, which focuses on Dark Skies and astronomy. The Quality Lighting Teaching Kits and the Galileoscope are two of the cornerstone projects in that theme. There will also be other events at this meeting pertaining to IYL2015, and more details about these will be in the next newsletter.
