Contribute to light pollution research with the Loss of the Night Android app!
Citizen science after hours…here are some citizen science projects you can do at night.
I’m going to take a quick bet and guess that every one who is reading this post has at least once gazed up at a clear sky and been fascinated by all the stars out there. If you’re out walking in the night with your friends or family, stargazing is probably the cheapest way to entertain yourself for hours on end.
Now, what if you could have all that fun, learn about constellations and contribute to science at the same time? There’s an app for that.
The science that we are talking about here is research on light pollution. Light pollution is the excessive artificial light that is added by sources such as poorly designed street lighting and over-illumination (imagine Times Square, Las Vegas or empty offices with the lights on all night).
Though we associate the increased availability of artificial lighting as a measure of human progress, it has unintended consequences. Birds misdirected by illuminated structures often suffer fatal collisions and freshly hatched turtles die because they wrongly migrate towards illuminated lands instead of the sea. Light pollution also significantly affects the diurnal or nocturnal nature of animals. As humans, our internal body clocks are also very tightly linked to the rhythmic changes in light between day and night. Artificial lighting can disrupt this rhythm leading to consequences to our health such as disorders associated with poor sleep patterns. So more light is not always good. Now that I’ve made you sufficiently concerned about this issue, I’m going to tell you how you can help!
Identifying stars in the night sky is one way by which we can measure light pollution. In a setting with lots of artificial lighting, the number of stars that are visible will be less. By gathering large amounts of information on star visibility from different locations around the world, citizen scientists can contribute extremely valuable data to the research effort on light pollution. Since not all of us are adept at identifying stars and constellations, several initiatives have come forward to help citizen scientists participate. One if them is the Loss of the Night (official site) (Verlust der Nacht in German) research network funded by the German Federal Ministry of Education and Research. The app was built in partnership with Cosalux. It investigates the causes and consequences of light pollution with the goal of developing improved and sustainable lighting concepts.
The data collected is sent to a larger international citizen science project called ‘GLOBE at Night’ which has been collecting and mapping this data since 2006. Over the past 8 years, more than 100,000 data points have been collected by Globe at Night from citizen scientists in 115 countries. Around 10,000 (and counting) of these data points have been contributed by the Loss of the night app. For 2014, the Globe at Night project plans to collect data about specific constellations at defined windows every month of the year. To start adding your own observations to this effort, I’ve come up with a simple guide below.
[Note – This month’s Globe at Night campaign is ending on 2/28! Send in your measurements whenever you can! Don’t worry, you can still participate outside of the campaign dates.]
