There is something that our moon likes to keep relatively hidden from us — its far side; the face we never see. This is because our rocky companion spins on its axis at around the same time that it takes to orbit the Earth. Though it is not always entirely hidden, sometimes the inter...
The attempt to trace and predict the motion of these planets was the beginning of the most famous upheaval in the history of science, eventually leading to the overthrow of primitive cosmology and the displacement of the Earth from the center of the universe. At the same time that the human...
How do we translate from the information provided by the Motion sensor to the celestial sphere? It’s all about the coordinate system. We’re all familiar with geographic coordinates that allow us describe a location on the surface of our planet. Any point on the surface ...
In a way, I've got some bad news, particularly to anybody who's come to Oxford from abroad. There's a real problem with snobbery, because sometimes people from outside the U.K. imagine that snobbery is a distinct...
The field of view of S-052 is 3.0 degrees, and the instrument is always sun-centered when it is operating. Therefore, any object viewed through it would have to come within a half-cone angle of 1.5 degrees from the center of the sun as measured from the earth. The earth-moon ...
Influence of Meteoroid Streams on the Lunar Environment: Results from LADEE Impacts on the lunar surface from meteoroid streams encountered by the Earth-Moon system can result in measurable enhancements in both the lunar atmosphere and dust environment. Here we describe the annual meteoroid streams inc...
A total solar eclipse occurs when the moon completely blocks the view of the sun for people in a narrow path across the earth’s surface. In a partial solar eclipse, the moon only partially blocks the sun, so it can be observed an area that is thousands of kilometers wide. What Are ...
To learn how to safely "observe" the Sun and a Solar Eclipse, consult your local planetarium or observatory. NASA's 5 Millenia of Eclipses: Solar Lunar MAJOR LUNAR FEATURES View the Moon's Features that are visible from Earth with binoculars or low-power telescope. Download NASA's Moon...
A total solar eclipse happens when the moon passes between the Earth and the Sun. As the moon blocks the face of the sun, it casts a shadow on Earth, and it becomes dark- the only light that remains is a ring that surrounds the moon. ...
aeverything on the moon is much lighter. walking on the moon is like jumping and flying. so we can jump higher on the moon than on the earth. 一切在月亮是更轻的。 走在月亮是象跳跃和飞行。 如此我们在月亮可以跳更高比在地球上。[translate] ...
