The 1st of this year's 4 eclipses will flit by like a ghost in the night between March 24 and 25. It's a penumbral lunar eclipse, visible in North America. Charts and more from Guy Ottewell here.
There are many cycles in the heavens. We're coming up to a noticeable cycle, the 1st eclipse season this year. It starts with a penumbral lunar eclipse.
Day and night are mostly equal on the equinox. There's a bit more daylight because the sun is a disk, not a point, and Earth’s atmosphere refracts sunlight.
The year's fastest sunsets are at the equinoxes, and the slowest are at the solstices. We're talking about how long it takes the sun to sink below the horizon.
