Larisza Krista’s movie of the 2012 total solar eclipse in Queensland, Australia didn’t require a zoom lens, a solar filter, a tripod, or a video camera. Instead, it took computer programming and hundreds of still photos. Krista developed a tool to process solar eclipse images from many sources and stitch them together, to create a solar eclipse “movie.”

Eclipse Will Have Atmospheric Impact
August 17, 2017
On August 21, outside of Lusk, Wyoming, Terry Bullett and Justin Mabie, like thousands of others across the United States, will be watching the solar eclipse cross the sky above. Totality there will last for less than two minutes, starting at 11:46 am. But Bullett and Mabie will be watching the eclipse with more than just their (appropriately protected) eyes: They’ve set up instruments in a field outside of Lusk to take research radar measurements before, during, and after the eclipse. Information captured by their instrument will help them study the ionosphere, a part of the upper atmosphere that’s critical for radio and other forms of communications.
Ozone Treaty Taking a Bite Out of US Greenhouse Gas Emissions
August 14, 2017
The Montreal Protocol, the international treaty adopted initially to protect and ultimately to heal Earth’s protective ozone layer, has significantly reduced emissions of ozone-depleting chemicals from the United States. But in a twist, a new study by NOAA and CIRES scientists shows the 30-year old treaty has also significantly reduced climate-altering greenhouse gas emissions from the United States.
