Citizen Science: Star by Star We Can Make a Galaxy

Posted by & filed under HTML + CSS, Think Tank.

Help us to fight against the light pollution and discover the Earth at night. Science has limited resources to study the incredible amount of light pollution data that we have. But working together, we can change the world.

Since 2003, almost 2 million photos have been taken from the International Space Station of Earth and the University of Complutence in Madrid (UCM) has decided to shed some light on light pollution with a collaboration effort of universal proportions. All the images taken by astronauts were provided by NASA, ROSCOSMOS, ESA, JAXA and CSA-ASC. Due to light pollution, we don’t really know all the places photographed and that’s where the citizens of Earth come in to help science with science.

Cities at Night is the website developed by UCM that highlights solutions and scientific evidence to light pollutions effects on life here on Earth. It also brings it down to our past-time of stargazing. The night sky is forever changing but we can do something about that. We have the technology. And you don’t need to be Steve Austin to help.

Crowd Crafting the Globe

The projects main coordination and develop came from Alejandro Sánchez de Miguel, José Gómez Castaño, Jaime Zamorano, Sergio Pascual and Jesús Gallego of UCM with support from Crowd Crafting which hosts the majority of Dark Skies and allows you to take a tutorial and begin sifting through images and tagging based off of your expertise in various sciences and just life in general. You see, algorithms cannot tell the difference between stars, cities, and other objects. People can and that’s where we all come in on this grand project.

There’s Even an App for That

Dark Skies has even released two apps to help georeference known cities and find unlocated images. The apps icon is courtesy of NASA/ESA JSC. You may also use Lost at Night and Night Cities ISS and just start contributing.

Loss of the Night

To better understand our lighting issues and the work that can be done to use light at night more efficiently for all of our health and for the planet itself, watch the video below that has been created by the team to promote this project.

 

Randall Munroe: Comics That Ask “What If?”

Posted by & filed under Think Tank.

Randall Munroe sketches elegant and illuminating explanations of the weird science and math questions that keep geeks awake at night … [He] answers simple what-if questions (“what if you hit a baseball moving at the speed of light?”) using math, physics, logic and deadpan humor. In this charming talk, a reader’s question about Google’s data warehouse leads Munroe down a circuitous path to a hilariously over-detailed answer — in which, shhh, you might actually learn something.

–This talk was presented at an official TED conference, and was featured on TED.com
