umbra

1 As you can imagine, the most spectacular eclipses occur when an object enters the umbra.

2 But if the Moon is at its furthest the umbra can disappear, leaving just an antumbra, or a very brief umbra.

3 Inside the umbra zone, there are 10,235 square miles of public domain land, located entirely in Oregon, Idaho and Wyoming:

4 Shaped like a cone extending into space, the umbra has a circular cross section that can be most easily seen during a lunar eclipse.

5 If a spot lasts and develops, it usually consists of two parts: an inner darker core, the umbra, and a surrounding less dark region, the penumbra.

6 An eclipse of the Moon is total only if the Moon’s path carries it though Earth’s umbra.

7 This full moon is also a partial lunar eclipse, according to the experts at NASA, an imperfect alignment of the sun, Earth and moon that results in the moon passing through only part of Earth's umbra.

9 Ideally, your goal should be to stand beneath the Moon’s darker, inner shadow — the umbra.

10 Indianapolis, Indiana The umbra will cover a wide swath of Indiana, but most of the attention will focus on the state’s capital city.

11 They were unable to see a total view of the eclipse because the station did not pass through the moon's umbra, according to NASA.

12 When that happens, the Earth blocks most of the light from the Sun, and the Moon is then plunged into our planet’s shadow, also called the umbra.

13 If the Moon does not enter the umbra completely, we have a partial eclipse of the Moon.

14 As the moon's position between the Earth and sun casts a shadow on North America, that shadow, or umbra, will travel along the surface from west to east at more than 1,500 miles per hour along the path of totality.

15 When a lunar eclipse happens, the moon appears to darken as it moves into Earth’s shadow, which is called the umbra.

16 “Having once stood in the umbra, the Moon’s shadow, during a solar eclipse, we are driven to do so again and again, whenever the Moon moves between the Earth and the Sun.”

17 It’s a minefield of jargon such as first contact and umbra, and of things to look for like shadow bands and Bailey’s beads.

18 The darkest part of the moon's shadow - the umbra - causes a total solar eclipse.

19 The formation of this spiral structure may be caused by the anti-clockwise spin of umbra "A".

20 The moon's shadow seen on Earth today, called the umbra, travels at more than 1,500 miles per hour, according to NASA.
