Why Same Side of the Moon Always Face The Earth ? | Explained | Deep Science Documentary Tapes

Our lunar companion rotates while it orbits Earth. It's just that the amount of time it takes the moon to complete a revolution on its axis is the same it takes to circle our planet — about 27 days. As a result, the same lunar hemisphere always faces Earth.

Also know, why does the same side of the moon always face Earth?


Only one side of the Moon is visible from Earth because the Moon rotates on its axis at the same rate that the Moon orbits the Earth – a situation known as synchronous rotation, or tidal locking. The Moon is directly illuminated by the Sun, and the cyclically varying viewing conditions cause the lunar phases.

Furthermore, does the moon rotate around the Earth? The moon orbits the Earth once every 27.322 days. It also takes approximately 27 days for the moon to rotate once on its axis. As a result, the moon does not seem to be spinning but appears to observers from Earth to be keeping almost perfectly still. Scientists call this synchronous rotation.

Beside above, does everyone on Earth see the same side of the moon?

Everyone sees the same phases of the Moon, but people south of the equator who face North to see the Moon when it is high in the sky will see the Moon upside down so that the reverse side is lit. The Moon goes around the Earth in a single day.

Why do we see moon phases?

Just like the Earth, half of the Moon is lit by the Sun while the other half is in darkness. The phases we see result from the angle the Moon makes with the Sun as viewed from Earth. We only see the Moon because sunlight reflects back to us from its surface.

Orbital Mechanics How Things Works

  Orbital Mechanics How Things Works YouTube Video : Deep Science | Documentary Tapes Gravity & Mechanics PAGE 4 OF 4 ON THIS PAGE How Orbits Work The Key to Space Flight Orbiting a Real Planet A Periapsis by Any Other Name Freefall How Orbits Work These drawings simplify the physics of orbital mechanics, making it easy to grasp some of the basic concepts. We see Earth with a ridiculously tall mountain rising from it. The mountain, as Isaac Newton first described, has a cannon at its summit. Of course, in order to make their point, the cartoons on this page ignore lots of facts, such as the impossibility of there being such a high mountain on Earth, the drag exerted by the Earth's atmosphere on the cannonball, and the energy a cannon can impart to a projectile ... not to mention how hard it would be for climbers to carry everything up such a high mountain! Nevertheless, the orbital mechanics they illustrate (in the absence of details like atmosphere) are valid. N...

Hubble Captures Giant Star on the Edge of Destruction In celebration of the 31st anniversary of the launching of NASA's Hubble Space Telescope, astronomers aimed the renowned observatory at a brilliant "celebrity star," one of the brightest stars seen in our galaxy, surrounded by a glowing halo of gas and dust. The price for the monster star's opulence is "living on the edge." The star, called AG Carinae, is waging a tug-of-war between gravity and radiation to avoid self-destruction. In celebration of the 31st anniversary of the launching of NASA's Hubble Space Telescope, astronomers aimed the renowned observatory at a brilliant "celebrity star," one of the brightest stars seen in our galaxy, surrounded by a glowing halo of gas and dust. Credits: NASA, ESA, STScI The expanding shell of gas and dust that surrounds the star is about five light-years wide, which equals the distance from here to the nearest star beyond the Sun, Proxima Centauri.

Voyager 1 Is Detecting a 'Hum' of Plasma Waves Interstellar Space

  Voyager 1 Is Detecting a 'Hum' of Plasma Waves Interstellar Space             Voyager 1 Is Detecting a 'Hum' of Plasma Waves Interstellar Space video In the emptiness of space, Voyager 1 detects plasma 'hum' Voyager 1—one of two sibling NASA spacecraft launched 44 years ago and now the most distant human-made object in space—still works and zooms toward infinity. The craft has long since zipped past the edge of the solar system through the heliopause—the solar system's border with interstellar space—into the interstellar medium. Now, its instruments have detected the constant drone of interstellar gas (plasma waves), according to Cornell University-led research published in Nature Astronomy. Examining data slowly sent back from more than 14 billion miles away, Stella Koch Ocker, a Cornell doctoral student in astronomy, has uncovered the emission. "It's very faint and monotone, because it is in a narrow frequency bandwidth," Ocker said. "...
