We know the equinox sun rises due east and sets due west. But what happens at Earth's poles? Turns out the North Pole sun is above the horizon all day long. And it looks exactly the same at the South Pole!
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.
We're counting down to the April 8, 2024, total solar eclipse, which will cross North America. Colors look eerie just before the moon covers the sun. Why?
Constellations and asterisms are patterns of stars. Some asterisms consist of stars from different constellations, and some are part of one constellation.
