Red moon at night; stargazer's delight
NOAO offers front-row seat to lunar eclipse
Monday night's lunar eclipse proved just as delightful as expected to those able to view it. On the East Coast, cloudy skies may have gotten in the way, but at the National Science Foundation's National Optical Astronomy Observatory (NOAO) near Tucson, Ariz., the skies offered impressive viewing, as seen from the pictures provided here.
Nicknamed a "blood moon," this lunar eclipse's color was similar to the majority of lunar eclipses. This has to do with the Earth's atmosphere's propensity for longer-wavelength light (e.g., the reds, oranges and yellows seen in sunrises and sunsets). However, according to NOAO Astronomer Stephen Pompea, the lunar eclipse's hue means more than just a pretty moon.
"The study of the color of lunar eclipses can be used to understand dust in the stratosphere including the amount and particle size of dust injected by volcanic eruptions," he said. "Understanding the amount of dust can help scientists create better models of climate change."
For those who missed this lunar eclipse, fear not. Three more are to occur fairly soon: Oct. 8, 2014; April 4, 2015 and Sept. 27, 2015.
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2017, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards.
