Our Moon reaches the first quarter phase on Wednesday.
"First quarter actually means half Moon," said John Sabia, Keystone College Assistant Observer. "The half that is illuminated is on the right side. That's the part we'll be looking at through the telescope on the right side."
Sabia also explained what Regulus is.
"Regulus is the heart of the lion, of course. It's a bright star. You might want to use binoculars on it. You could actually see some color. A little reddish orangeish color to Regulus," he said.
The first quarter Moon and Regulus will be close together in the evening sky on Wednesday.
"You're going to have to look early because it's in the west, and you don't want to wait too long because it will be setting and getting lower on the horizon. You might have trees in your way, so get out there early," said Sabia.
Sabia says the first quarter phase of the Moon is a good time to bust out the binoculars or telescope.
"You're going to see a lot of shadows coming up to that place we call the terminator between darkness and light. If you move off to the right where it's still in the light, you can still see a lot of detail on the craters," he explained. "It's not like looking at the full Moon where it's just black and white. You won't see those craters."
In addition to seeing the Moon and Regulus this week, Sabia also points out that Jupiter reaches the west quadrature later in the week.
"It's a time when we can see the planet coming up higher in the sky so we can observe it easily," he said.
If you're using a stronger telescope, look for Jupiter's Great Red Spot.
"It's actually growing smaller. When I looked at it, it was humongous back in the 70s. Now it's much smaller. It's shrinking. It has been shrinking," added Sabia.
