Globe at Night Call-To-Action

Call to action map

Ever wonder what happens to your Globe at Night measurements once you’ve submitted them? Both scientists and citizen-scientists have used them in a variety of projects. Most projects need however multiple data points at the same location over time. This map shows 5,000 locations on Earth where someone made an observation in the past but there hasn’t been a new observation within the last five years. If you can make an observation near to one of these points (or if you have a friend who lives close to one of them), it would be extremely helpful. Also, try taking measurements where no data points have been taken yet! See Global Astronomy Month’s Call-to-Action on behalf of Globe at Night.

The International Year of Light

Google+ Hangouts

Cosmic Light IYL Logo On behalf of the International Year of Light 2015, the International Dark-Sky Association is hosting a series of 6 Google+ Hangouts, one every two months in 2015). Each hangout will address how light pollution affects specific topics. The first Google+ Hangout occurred on February 23, featured experts in the field of health, and addressed the effects of light pollution on human health. The second Hangout occurred on March 19 and featured experts in the field of astronomy who addressed the effects of light pollution on astronomy and astronomical research. The remaining topics (in order) will be on safety, wildlife, energy, and wildlife and cultural heritage. Upcoming hangout dates and times will be featured in the next Globe at Night newsletter, so stay tuned!

Dark Sky Meter App

Dark Sky Meter iPhone app

The International Year of Light has just released its own Dark Sky Meter app for iPhones! All you have to do is point your phone at the night sky, and it measures the night sky brightness for you. Then, you can use the IYL DSM app to easily submit your measurement which will be entered into the Globe at Night database and be used by researchers.

Cosmic Light IYL2015: Cosmic Light EDU kit

Cosmic Light EDU kit

The Cosmic Light EDU kit has been launched! The main goal for this project is to involve schools around the globe in awareness campaigns for light pollution and to discover the nature of light. The project has assembled an educational kit, with simple resources and activities to support teachers. There are many and varied networks involved in this project so participants can benefit from many opportunities for a rich cultural interchange. The project aims to target diverse social and cultural audiences, and there is a special component designed for children with visual impairment incorporated in the kit to promote inclusivity. The kit will have printable materials, several digital tools and resources and training efforts will be implemented in order to empower teachers to make full use of the kit The campaign will reach teachers and students in 100 countries around the world. Take a closer look at all the resources featured in the Comic Light EDU kit.

Globe at Night and Technology

Light Pollution Simulator

Check out this awesome new light pollution simulator that’s free! You can play around with the number of lighting poles, height of poles, type of lighting bulb, output power of the bulbs, and the type of lighting shield used and see how that changes the resulting light pollution.

Time-lapse Video

Time lapse screen grab

Check out this amazing time-lapse video that is part of filmmakers Gavin Heffernan’s and Harun Mehmedinovic’s SKYGLOW Project, a multi-media initiative that seeks to highlight the problem of urban light pollution around the world. In this time-lapse video, the Los Angeles’s city sky has been painstakingly cut out and replaced with composites of starscapes from dark sky preserves such as Death Valley and the Grand Canyon to show what Los Angeles would look like without light pollution.
