The internet has become a priceless tool for the citizen-science movement, in which private citizens all over the world can make meaningful contributions to science. With as little as a computer and some curiosity, you can help scientists determine targets for space telescopes, or look for signs of life on Kepler planets. Some projects, like…
Modern technology allows amateurs around the globe to collaborate in ways never before possible. The following is a collection of some of the research projects we find most interesting, many of which involve collaboration with professional astronomers at universities and other research organizations. These projects generally require more sophisticated equipment or technical expertise than the…
The American Medical Association has released a report detailing several possible health concerns related to nighttime light exposure. But some lighting researchers worry the conclusions are more alarmist than is warranted.
