When a meteoroid, comet, or asteroid enters the Earth's atmosphere at a speed typically in excess of 45,000 mph, aerodynamic heating of that object produces a streak of light, both from the glowing object and the trail of glowing particles that it leaves in its wake. This phenomenon is called a meteor or "shooting star". A series of many meteors appearing seconds or minutes apart and appearing to originate from the same fixed point in the sky is called a meteor shower. more... |
The Galactic Center is the rotational center of the Milky Way. The estimates for its location range from 7.6 to 8.7 kiloparsecs (about 25,000 to 28,000 lightyears) from Earth in the direction of the constellations Sagittarius, Ophiuchus, and Scorpius where the Milky Way appears brightest. There is strong evidence consistent with the existence of a supermassive black hole at the Galactic Center of the Milky Way. more... |
The Wah Wah Mountains are a north-south trending range in west-central Utah, part of the larger Basin and Range Province. It is bounded by Pine Valley to the west, Wah Wah Valley to the east, the Escalante Desert to the south, and on trend with the Confusion Range to the north. The Wah Wah Mountains are located in Beaver and Millard counties. State Route 21 bisects the range, crossing over Wah Wah Summit at about 6,500 feet (1,980 m) above sea level. Elevations range from about 6,000 feet (1,800 m) at the mountain front to 9,393 feet (2,863 m) in the southern Wah Wahs. more... |
