Eclipses do not happen every day, but they are not as rare as some might think. On average, there are two to four eclipses per year, although some years may have none, while others may have up to seven. This variation is due to the complex interactions between the Earth’s orbit aro...
Two solar eclipses separated by a Saros cycle have certain similarities: they occur at the same lunar node, with the Moon roughly at the samedistance from Earth, and they take place around the same time of the year. The path of totality for the eclipses also looks very similar on a map...
—How long can the brain survive without oxygen? "We're gaining in our understanding of the various actions on key receptors in the brain that produce anesthetic and sedative effects," Harter said. "But we still don't have a comprehensive understanding of precisely how it works." One of th...
America’s most special places will always be beautiful, but a warming climate forces us to accept that they can’t be frozen in time.
How Long Does Totality Last? A total solar eclipse can last for several hours and totality can range from a few seconds to 7.5 minutes. The longest total solar eclipse of the 21st century took place onJuly 22, 2009, when totality lasted 6 minutes and 39 seconds!
How long do lunar eclipses last? It depends on how deeply the moon penetrates into the Earth's umbra and how far away the moon is from the Earth. When the moon is near its closest point to Earth (perigee) it is moving much faster in its orbit as compared to when it's near its ...

Ozone depletion has resulted in increasing ultraviolet-B radiation, and increasing greenhouse gases and decreasing stratospheric ozone have altered Antarctica's climate. How do mosses thrive photosynthetically in this harsh environment? Antarctic mosses take advantage of microclimates where the combination of...
man to go where no man has gone before in space. It would be possible to make trips to Jupiter and even beyond the heliopause, the point at which thesun's radiation ends. But it will still be a long time before astronauts are asking their starship's helmsman to take them to warp ...
Find a suitable place to view the eclipse. You should be able to see a lunar eclipse as long as you are on thenight-side of the Earthwhen the eclipse occurs. Rural areas with little or no artificial lights have the clearest skies and the best viewing conditions. Urban areas, on the ot...
