It would look like a solar eclipse! What happens is that Earth gets in the way between the Sun and the Moon. From Earth we see the Moon disappear, from the Moon one would see the Sun disappear. Earth is fix on the Moon's sky, because the Moon always turns the same side towards Earth. Earth as seen from the Moon has phases, like the Moon has when seen from ...

That's no good idea. Earth wouldn't necessarily fall into Jupiter in the short run, provided it orbits Jupiter fast enough (within about 1.7 days), and on a circular orbit, but we would risk to collide with Io, destroy it by tidal forces, or change its orbit heavily. The other Galilean moons would get out of sync and change their orbits over time. Tides ...

The water for high tides needs to come from somewhere; the mean sea level should stay approximately constant, as long as wind is neglected. That way tides are a kind of oscillations. In the first of the two diagrams a low low tide is followed by a high high tide, and a high low tide is followed by a low high tide. That way the mean sea level, averaged over ...

As an complement to the other answers, let me address the question of why planets tend towards tidal locking. In short, the torque applied by the differential gravitational force between both sides of the surface of the planet induces friction, which in turn dissipates aways the excess spin of the (proto) moon when it is not tidally locked. When locking ...

It's mainly by the clear definition of the rings, and their mere existence. Without a moon the rings would be short-lived, hence unlikely to be detected just in time shortly after they've formed. And they would tend to wash out to broader rings. The space between the rings seems to be empty. That's easier to explain by one or more moons keeping the gap ...

The synodic month is the "average period of the Moon's revolution with respect to the line joining the Sun and Earth". However, the Earth also moves in its orbit around the Sun during this month. From our vantage point, the Sun has appeared to move in the sky with respect to the background stars, in the same direction as the Moon moves in the sky with ...

No, not all total lunar eclipses will turn the Moon deep red. Most of them do, but not all. If you were standing on the Moon during the eclipse, you'd see the Earth passing in front of, and obscuring, the Sun. But the Earth will never become fully dark, even when the Sun is fully covered. A bright ring will always surround the Earth. Why? That ring is ...

It would look like this (actual picture of the Earth, seen from the Moon, during a lunar eclipse): Link to full page: http://apod.nasa.gov/apod/ap140407.html The Earth would appear surrounded by a bright ring, even though the Sun is completely hidden behind it. The ring is sunlight refracted through the atmosphere. It's basically all the sunrises and ...

Yeah you'll see earth as all dark If it is total lunar eclipse, In Lunar eclipse technically earth comes in between of sun and moon. because of which sun rays don't reflect from the surface of moon. Now answer to your question, As earth's one part is obstacle to light the other part will be darker. As you are standing towards shadowed side of earth. you ...

Pretty most all lunar eclipses will turn the moon red like that. The amount of redness does vary, and sometimes so little light gets to the sun it is almost completely dark. However the redness is so typical of a lunar eclipse that NASA describes it as a "characteristic orange-red color". That link has a neat table with a categorization of the colour ranges. ...

i would rather call the streaks you are referring to as ridges. the surface of the moon is ofcourse not a perfect sphere and the same way the earth had ups and downs, there are ridges on the moon too. you say that most of them are diagonal - top-left to bottom-right but on the right hand corner of the image, there are ones vertical ones. So, there is no ...
