Q: What's in the "dark side" of the moon?

A: Short answer? He is uncertain. Sound recognition! But to name it. Because they do not talk about the Pink Floyd chart or the French script, people who say "dark side of the moon" almost always describes the moon long Out, despite being permanently remitted by our planetside, see as much sunlight as the side of the Earth.

You may already know that. But! Did you also know that slides across the moon are increasing? Or are there no specific areas of ground, indeed, covered in permanent darkness?

To understand why, you must now have a & # 39; understand why one side of the moon is ever marked away from Earth. For our people here on earth, our planet's natural satellite seems to have ever come. But it's turned all the time – it's just a & # 39; Spinning axis and loops around the same plan: once every 27 days or so. When a cosmic body goes around her & her; parent and axis at the same level, radians say it is "fastened".

No moon was born like this. Seals think, as many natural satellites, has begun to Spinning life at a very different level. (In the case of our moon, the scientists think it's been once faster about axis.) Over time, the planet's planet affected chips on surface of the moon, which has been & # 39; move into synchronization with its orbital time. This wonder is very common: many of Saturn's and Jupiter's knees are quickly locked with their parents' plan.

So maritime is why we did not think what the other side of the moon was like until 1959, when the Soviet survey Luna 3, The first pictures of the landscape are full of shades. We have a good look at him since: in 1968, bouts on NASA's Apollo 8 mission strikers; First people who watched the long side of the moon with their own eyes. The NASA Lunar Orbiter has been packaging full moon surface in a good solution since 2009. And in the " The first day of 2019, China's daughter; First country to launch spacebox and rover usage on its & # 39; moon is always hidden. China Changes 4 on land and Jade Rabbit 2 rover brings humanity to her; The first glimpse of this remote lunar scene.

But the truth is: You do not need a spacecraft to look beyond the moon. Although you can only see 50% of the lunar blog at any time, bonus ideas on its surface constantly tell themselves to careful viewers. Indeed, throughout a lunchtime, up to 59 percent of the moon surface will be visible on Earth – because they know what to look.

Browse this photo from NASA's Studio Science Visualization. It was done by using satellite images captured by Orbiter Lunar Recognition. The degree changes without any doubt you are not aware of: How the moon's position moves connected to its & # 39; sunshine and earth, cups dark and turn back from the front that is tightly locked to the; Our planet (as long as it is a reverse return that opposes the face). But this animation – which is divided by two and a half times; move to one thing 13-page to show something about the moon you did not notice before: The type of moon … a & # 39; move.

Sealers report these behaviors, and they are caused by a "#; look at the moon axis and the orbit's idyllic shape. The level of axis that is associated with the Earth means that its & # 39; moon seemed to be like it would be; slowly slowly and slowly, with a # 39; looking at the north and south poles. Similarly, the edge of the moon is a Bringing a small card over against it, which enables our people to land the Earth; peers across the eastern and west sides as long as it is; go back and forth, not to be different from: party parrot: in slack. (Its neo-regular orbit also explains the obvious changes of the moon, due to the different distance from Earth.)

And the loop of the moon's axes brings something other interesting: balls of the moon surface that are true, indeed, all night:

The image above is the illuminating map of the south row pole. It is a comparative photograph taken from over 1,700 images taken by the Orbiter Lunar Revival over six months. Parts of the pole that saw any light at that time did not appear black; Those who have seen a bright light appear white; the green divisions saw something different. As a point of information, the black circle is near the middle of the image of the Shackleton Crater, the skin affects 13 miles by the edge that leaves long shadow across the inside.

Everything is said: "There may not be a darker side of the moon" in technology, but "crudes of eternal darkness" – which even sounds & # 39; faster than proof.
