A waxing gibbous moon appears more than half lighted, but less than full. It rises before sundown and sets somewhere between midnight and dawn.
The 1st quarter moon happens on April 1, 2020, at 10:21 UTC. As viewed from anywhere on Earth, a 1st quarter moon is at its highest in the sky at sunset, looking like half a pie.
The moon reaches its last quarter phase on March 16, 2020, at 09:34 UTC.
The full moon you’ll see this weekend will rise at sunset. It’ll be highest up in the middle of the night when the sun is below our feet. It’ll set when the sun rises. But why does it look full?
New moons generally can’t be seen. They cross the sky with the sun during the day. This month’s new moon happens on February 23 at 15:32 UTC.
A waning crescent moon is up in the east before sunrise. It’s waning toward new moon, when the moon will be between the Earth and sun.
One Earth. One sky. One moon phase (more or less) from all of Earth. So why (and how) does the moon look different from different parts of Earth?
The most important key is to think of the moon as a world in space, with a day and night side.
A waning gibbous moon is a moon between full and last quarter. Watch for this moon phase from late night through early morning.
Many people report seeing earthshine on a waxing crescent moon. That’s when the darkened portion of the crescent glows dimly with light reflected from Earth.
It’s rare to see a moon within 24 hours of new moon. This week, we received a couple of images of even-younger moons. What’s the youngest moon you can see? Info and pics here.
Half the moon always faces us. And half the moon is always lit by the sun. But, in the language of astronomers, there are no ‘half moons.’
