Although August’s total solar eclipse was over in minutes, analysis of the 50,000 photos uploaded to the Eclipse Megamovie website is a time-consuming job, so team leaders are asking citizen scientists for help.
The images have been put online at Zooniverse so that the public can scan and categorize them, a project dubbed Megamovie Maestros I.
Initially, volunteers are being asked to determine what the project’s photographers actually captured by identifying eclipse phases, diamond rings, Baily’s beads and other interesting phenomena.
The photos, snapped by thousands of recruited volunteers, have already been stitched together once by Google to create a first round extended view of the eclipse (aka the Megamovie). The Zooniverse project will help the team improve the Megamovie, and ultimately, better understand the behavior and mechanisms of the solar corona. Analysis of individual images will provide even more scientific data, according to the project team.
People who are more technically inclined are invited to dive into the project’s entire image database to see what they can discover or create (see instructions here). That could mean constructing a collage, spotting an unusual phenomenon or even making a better Megamovie.
“It’s a great way to relive the eclipse and see some stunning eclipse imagery, thanks to our oh-so-talented volunteers,” said Dan Zevin, who is with the Multiverse education team that is leading the Eclipse Megamovie project at UC Berkeley’s Space Sciences Laboratory.

Infraphylum Agnatha
Agnathans are a group of jawless fishes that include Myxini (hagfish) and Petromyzontidae (lampreys). Pictured above are Petromyzontidae, also known as lampreys. The name “lamprey” is derived from Latin meaning “stone licker.” The most well known lamprey species are a parasitic and feed by boring into the flesh of other fish to suck their blood. However there are a some species of lamprey that non-parasitic.
Scientists using the IceCube Observatory located near the South Pole have discovered that neutrinos can be absorbed by our Planet Earth. With almost no mass and no charge, these particles rarely interact with matter. Yet tens of trillions of neutrinos pass through our bodies every second. Previous theories predicted that at high energies, neutrinos can be expected to interact with matter and be absorbed by the Earth instead of passing through the planet. “We knew that lower-energy neutrinos pass through just about anything, but although we had expected higher-energy neutrinos to be different, no previous experiments had been able to demonstrate convincingly that higher-energy neutrinos could be stopped by anything,” said Penn State Professor Doug Cowen. “However, the neutrino does have a tiny probability to interact, and this probability increases with energy. That probability is what scientists call the neutrino cross section.” The new measurements recorded by IceCube determined the neutrino cross section energies to be about 6.3 TeV and 980 TeV, energy levels significantly higher than previously measured.
