Why Can I Sometimes See the Moon During the Day?

WHY? is our attempt to answer all the questions every little kid asksHave a question? Send it to why@mentalfloss.com.

The Sun comes out in the morning and sets at night, and then the Moon rises. Right? Then how come we can see the Moon during the day sometimes? 

The Moon and the Sun don’t actually take turns in the sky. The Earth orbits around the Sun, and the Moon orbits around the Earth. All three are spinning in space all the time. When the part of the Earth you're standing on faces the Sun, the sky is filled with sunlight. That's daytime. When your part of the planet is turned away from the Sun, that's night time. The Moon moves through the sky night and day. Much of the time, the sunlight is so bright, we can't see the Moon during the day.

The Sun is a very hot ball of gas. Like a fire or a light bulb, the Sun gives off both heat and light. But the Moon is made of rock, not gas, and it is not hot or bright at all. What we call moonlight is actually sunlight bouncing off the Moon, the same way that sunlight bounces off the reflectors on your bike. They look like they’re lighting up, but they’re really just passing the sunlight along.

How bright the Moon is depends on where it is in the sky. If the Moon is between the Earth and the Sun, it doesn’t bounce any sunlight to us at all, and it is very hard to see, even at night. This is called a new moon. When the Moon is behind the Earth, it shines very brightly. We call this a full moon. You can see in this video how the Moon gets different amounts of sunlight as it orbits around the Earth. That changes how it looks to us. Sometimes, when the Moon is very bright, we can see it even during the daytime.

Let's try an experiment! Tonight, get a flashlight and go into your room. (Bring your mom or dad with you if that seems a little scary.) Turn off the lights, and turn on the flashlight. You'll notice that it’s very easy to see the bright light of the flashlight. Keep the flashlight on, then turn the room lights back on. Now the light from the flashlight is a lot harder to see. It's the same with the Moon. At night, it’s easy to see the Moon, because it’s the brightest thing in the sky. But during the day, the Moon has to be very bright for us to notice it. That means that the best time to see a daytime moon is in the morning just before and just after the full moon.

Late MythBusters Star Grant Imahara Honored With New STEAM Foundation

Fans of MythBusters and White Rabbit Project host Grant Imahara were saddened to hear of his passing due to a brain aneurysm in July 2020 at the age of 49. Imahara, a graduate of the University of Southern California, used the television medium to share his love of science and engineering. Now, his passion for education will continue via an educational foundation developed in his name.

The Grant Imahara STEAM Foundation was announced Thursday, October 23, 2020 by family and friends on what would have been Imahara’s 50th birthday. The Foundation will provide mentorships, grants, and scholarships that will allow students from diverse backgrounds access to STEAM education, which places an emphasis on science, technology, engineering, arts, and math. (Formerly referred to as STEM, the “A” for art was added more recently.)

Imahara had a history of aiding students. While working at Industrial Light and Magic in the early 2000s, he mentored the robotics team at Richmond High School to prepare for the international FIRST Robotics Competition. Whether he was working on television or behind-the-scenes on movies like the Star Wars prequels and The Matrix sequels, Imahara always found time to promote and encourage young engineering talent.

The Grant Imahara STEAM Foundation’s founding board members include Imahara’s mother, Carolyn Imahara, and close friends Don Bies, Anna Bies, Edward Chin, Fon H. Davis, Coya Elliott, and Ioanna Stergiades.

“There are many students, like my son Grant, who need the balance of the technical and the creative, and this is what STEAM is all about,” Carolyn Imahara said in a statement. “I’m so proud of my son’s career, but I’m equally proud of the work he did mentoring students. He would be thrilled that we plan to continue this, plus much more, through The Grant Imahara STEAM Foundation.”

Imahara friend Wade Bick is also launching an effort in concert with the USC Viterbi School of Engineering to name a study lounge after Imahara. Donations can be made here.

You can find out more about the foundation, and make a donation, on its website.
