A lunar light show circled the globe today, rewarding many moongazers with bright, crisp detail of the full moon's craters and basins. Called a "perigee" moon by scientists, the annual phenomenon occurs once a year. NASA said the moon appears about 14% bigger and 30% brighter than other full moons. That's because it will be as close to Earth as it will get for a while -- just over 221,000 miles away. Residents of the mainland United States received similar conditions at 8:34 p.m., the peak of this year's "super moon." The best time to see the event is just as the moon crosses Earth's horizon. The moon always looks biggest then, although the reason why is a bit of a mystery. Viewing the moon behind buildings and trees creates an optical illusion so it appears even larger, making it a perfect time to try to grab some beautiful pictures.
So why is this full moon so super?
As the moon makes its elliptical orbit around Earth, there are specific times when it is closest to and farthest away from our planet. Apogee occurs when the moon is farthest away from us, and perigee occurs when it is closest. Experts say viewers may not notice a noticeable size difference, given there are no reference points when the moon is high overhead. "'Super moon' is a situation when the moon is slightly closer to Earth in its orbit than on average, and this effect is most noticeable when it occurs at the same time as a full moon," James Garvin, chief scientist at NASA's Goddard Space Flight Center, said in 2011. "So, the moon may seem bigger although the difference in its distance from Earth is only a few percent at such times." "I love nature," said Wade, 31, who has a corporate day job and an online vintage clothing shop. The super moon is a natural phenomenon, and that is what is so awesome about it.
