On April 15, 2014, an extraordinary series of total lunar eclipses will begin in the United States. This series, called a lunar eclipse tetrad, will result in four red moons over the course of a year and a half. NASA explains the significance behind this phenomenon, and sheds light on how the moon transforms into a bright red orb. Via TED-Ed
When and where it will be visible:
The first total lunar eclipse of 2014 occurs in the overnight hours tonight (April 14) and will be visible across most of North America, South America, Hawaii and parts of Alaska. Depending on your location, it begins either late tonight or in the wee hours of Tuesday, but as with every skywatching event, you can only see it if Mother Nature cooperates.
Tonight’s lunar eclipse runs from 12:53 a.m. EDT (0453 GMT) to about 6 a.m. EDT (1000 GMT). If bad weather spoils your view, or you live in Europe or elsewhere outside the visibility zone, you can always watch live webcasts of the total lunar eclipse on Space.com, courtesy of NASA, the Slooh community telescope, the Virtual Telescope Project.
What happens during lunar eclipses?
Lunar eclipses happen when the moon is in the full moon stage and passes through part or all of the Earth’s shadow, darkening the moon’s typically bright glow. During a total lunar eclipse, the moon is entirely immersed in Earth shadow, and can take on a dusky “blood red” colour due to the scattering of sunlight through the edges of Earth’s atmosphere. Such moons are sometimes nicknamed “Blood Moons.”Tonight’s lunar eclipse is the first of four consecutive total eclipses of the moon between April 2014 and September 2015 in what scientists call a lunar eclipse “tetrad” series. The next total lunar eclipse will occur on Oct. 8 and is also expected to be visible from much of North America. Via Space.com
