Our sky looks blue because our atmosphere scatters the blue light waves but Mercury doesn’t have any atmosphere so the sky is always just black even during the day when the sun is out. Also because there is no atmosphere it gets 800 degrees during the day and -290 degrees at night. Also my friend Benji got to see a SpaceX rocket launch and his mom took this picture (Sam, 9).
Mercury is the fastest planet in our solar system. It goes around the sun 4 times faster than the earth so a year on Mercury is 88 Earth days. But Mercury rotates really slow so a day on Mercury lasts for 59 Earth days. I wrote about Mercury on our blog when I was 7 but I don’t think I knew what I was talking about (Joel, 13).
We were in Alaska recently and the moon there was noticeably different from the moon we see down south. At 60 degrees North the full moon was tilted almost 90 degrees clockwise from what we see at about 38 degrees. Above is a picture I took of the moon in Alaska and below is one I took in California. We always only see one side of the moon but we can see different angles of it (Titus, 14).
While flying over some clouds on our trip to Alaska I looked down and saw the shadow of our plane pass through a full circle rainbow. I took a picture of it with my GoPro. The scientist sitting in front of us got an even better picture with his camera and thought what we were seeing was very unusual. All rainbows are actually full circles but we only see half of it from the ground because of the angle (Joel, 13).
The sun’s light contains every color of the rainbow. The sun’s light is white which is every color combined. When light hits an object it absorbs every color but the one it is. That’s what bounces back at our eye. A rainbow is when water droplets act like prisms and bounce all the colors back. Here is a picture of me and a rainbow I saw in Alaska (Nate, 11).
