During a small part of that orbit, it passes through a special region called Earth's magnetotail, which stretches out on the night side of our planet. While inside the magnetotail, the Moon is protected from the Sun's radiation. But once it leaves the magnetotail, it is again exposed to the solar wind.",

While inside the magnetotail, the Moon is protected from the Sun's radiation. But once it leaves the magnetotail, it is again exposed to the solar wind. Scientists are actively studying this magnetotail region, and we're excited about what the Moon's monthly visits can teach us. Each time the Moon passes through, it gives us an opportunity to learn more about Earth's magnetic environment and how our planet protects itself from space radiation.\r\n\r\nThis is 4k fulldome imagery intended for projection in a planetarium or other hemispherical dome theater.",
