The land west of the fault was forced up and over the eastern side as the lunar crust contracted. In a May paper published in Nature GeoscienceThomas Watters and his coauthors provide evidence that this fault and others like it are still active and producing moonquakes today.

Seismometers left on the Moon by Apollo astronauts recorded hundreds of events between andincluding 28 shallow moonquakes. The study narrowed the locations of these quakes and found that many of them occurred near scarps, implying that the forces creating the scarps also caused the quakes, and they continue to shape the lunar surface.

The Lee Lincoln scarp was only about 13 kilometers from one of the epicenters identified by the scientists. The Apollo 17 astronauts drove their lunar rover onto the scarp during their second day on the lunar surface, and this remains the only extraterrestrial scarp visited by humans. The number of asteroid impacts to the Moon and Earth increased by two to three times starting around million years ago, researchers reported in a January 18 paper in the journal Science.

Earthrise in 4K In December ofthe crew of Apollo 8 became the first people to leave our home planet and travel to another body in space. But as crew members Frank Borman, James Lovell, and William Anders all later recalled, the most important thing they discovered was Earth. Witness the moment when the iconic "Earthrise" photograph was captured, recreated in this video using terrain data from NASA's Lunar Reconnaissance Orbiter and the astronauts' own audio.

Tour of the Moon 4K Redux Six years later, the tour has been recreated in eye-popping 4K resolution, using the same camera path and drawing from the vastly expanded data trove collected by LRO in the intervening years. The tour visits a number of interesting sites chosen to illustrate a variety of lunar terrain features. Some are on the near side and are familiar to both professional and amateur observers on Earth, while others can only be seen clearly from space.

Constantly shadowed areas near the poles are hard to photograph but easier to measure with altimetry, while several of the Apollo landing sites, all relatively near the equator, have been imaged at resolutions as high as 25 centimeters 10 inches per pixel.

The new tour highlights the mineral composition of the Aristarchus plateau, evidence for surface water ice in certain spots near the south pole, and the mapping of gravity in and around the Orientale basin. Moonlight Clair de Lune The piece was published in as the third of four movements in the composer's Suite Bergamasque, and how long does it take to charge a battery the other parts of this work, Clair is quiet, contemplative, and slightly melancholy, evoking the feeling of a solitary walk through a moonlit garden.

The visuals were composed like a nature documentary, with clean cuts and a mostly stationary virtual camera. The viewer follows the Sun throughout a lunar day, seeing sunrises and then sunsets over prominent features on the Moon. The sprawling ray system surrounding Copernicus crater, for example, is revealed beneath receding shadows at sunrise and later slips back into darkness as night encroaches.

The visualization uses what does a s video cable look like digital 3D model of the Moon built from Lunar Reconnaissance Orbiter global elevation maps and image mosaics. The lighting is derived from actual Sun angles during lunar days in Moon Phase and Libration, The data in the table for the entire year can be downloaded as a JSON file or as a text file.

The animation archived on this page shows the geocentric phase, libration, position angle of the axis, and apparent diameter of the Moon throughout the yearat hourly intervals. Until the end ofthe initial Dial-A-Moon image will be the frame from this animation for the current hour. Click on the image to download a high-resolution version with labels for craters near the terminator. Its laser altimeter LOLA and camera LROC are recording the rugged, airless lunar terrain in exceptional detail, making it possible to visualize the Moon with unprecedented fidelity.

This is especially evident in the long shadows cast near the terminator, or day-night line. The pummeled, craggy landscape thrown into high relief at the terminator would be impossible to recreate in the computer without global terrain maps like those from LRO.

The Moon always keeps the same face to us, but not exactly the same face. Because of the tilt and shape of its orbit, we see the Moon from slightly different angles over the course of a month. When a month is compressed into 24 seconds, as it is in this animation, our changing view of the Moon makes it look like it's wobbling.

This wobble is called libration. The word comes from the Latin for "balance scale" as does the name of the zodiac constellation Libra and refers to the way such a scale tips up and down on alternating sides. The sub-Earth point gives the amount of libration in longitude how to pay citibank credit card bill latitude.

The sub-Earth point is also the apparent center of the Moon's disk and the location on the Moon where the Earth is directly overhead. The Moon is subject to other motions as well. It appears to roll back and forth around the sub-Earth point. The roll angle is given by the position angle of the axis, which is the angle of the Moon's north pole relative to celestial north.

The Moon also approaches and recedes from us, appearing to grow and shrink. The most noticed monthly variation in the Moon's appearance is the cycle of phasescaused by the changing angle of the Sun as the Moon orbits the Earth. The cycle begins with the waxing growing crescent Moon visible in the west just after sunset. By first quarter, the Moon is high in the sky at sunset and sets around midnight.

The full Moon rises at sunset and is high in the sky at midnight. The how to fix galaxy note 2 quarter Moon is often surprisingly conspicuous in the daylit western sky long after sunrise. Celestial north is up in these images, corresponding to the view from the northern hemisphere. The descriptions of the print resolution stills also assume a northern hemisphere orientation. There is also a south-up version of this page.

From this birdseye view, it's somewhat easier to see that the how to remove security lug nuts of the Moon are an effect of the changing angles of the sun, Moon and Earth. The Moon is full when its orbit places it in the middle of the night side of the Earth. The First How to make a 3d model of solar eclipse of Aries is at the 3 o'clock position in the image. The sun is in this direction at the March equinox.

You can check this by freezing the animation at the mark, or by freezing the full animation with the time stamp near March 20 at UTC. This direction serves as the zero point for both ecliptic longitude and right ascension. The north pole of the Earth is tilted The tilt of the Earth is important for understanding why the north pole of the Moon seems to swing back and forth.

In the full animation, watch both the orbit and the "gyroscope" Moon in the lower left. The widest swings happen when the Moon is at the 3 o'clock and 9 o'clock positions.

When the Moon is at the 3 o'clock position, the ground we're standing on is tilted to the left when we look at the Moon. At the 9 o'clock position, it's tilted to the right. The tilt itself doesn't change. We're just turned around, looking in the opposite direction. The subsolar and sub-Earth points are the locations on the Moon's surface where the sun or the Earth are directly overhead, at the zenith. A line pointing straight up at one of these points will be pointing toward the sun or the Earth.

The sub-Earth point is also the apparent center of the Moon's disk as observed from the Earth. In the animation, the blue dot is the sub-Earth point, and the yellow dot is the subsolar point.

The lunar latitude and longitude of the sub-Earth point is a measure of the Moon's libration. For example, when the blue dot moves to the left of the meridian the line at 0 degrees longitudean extra bit of the Moon's western limb is rotating into view, and when it moves above the equator, a bit of the far side beyond the north pole becomes visible. At any given time, half of the Moon is in sunlight, and the subsolar point is in the center of the lit half. Full Moon occurs when the subsolar point is near the center of the Moon's disk.

When the subsolar point is somewhere on the far side of the Moon, observers on Earth see a crescent phase. The Moon's orbit around the Earth isn't a perfect circle.

The orbit is slightly elliptical, and because of that, the Moon's distance from the Earth varies between 28 and 32 Earth diameters, or aboutandkilometers. In each orbit, the smallest distance is called perigee, from Greek words meaning "near earth," while the greatest distance is called apogee.

The Moon looks largest at perigee because that's when it's closest to us. The animation follows the imaginary line connecting the Earth and the Moon as it sweeps around the Moon's orbit. From this vantage point, it's easy to see the variation in the Moon's distance. Both the distance and the sizes of the Earth and Moon are to scale in this view.

In the HD-resolution frames, the Earth is 50 pixels wide, the Moon is 14 pixels wide, and the distance between them is about pixels, on average.

Note too that the Earth appears to go through phases just like the Moon does. For someone standing on the surface of the Moon, the sun and the stars rise and set, but the Earth doesn't move in the sky.

It goes through a monthly sequence of phases as the sun angle changes. The phases are the opposite of the Moon's. During New Moon here, the Earth is full as viewed from the Moon.

Celestial south is up in these images, corresponding to the view from the southern hemisphere. The descriptions of the print resolution stills also assume a southern hemisphere orientation. There is also a north-up version of this page. The south pole of the Earth is tilted For example, when the blue dot moves to the left of the meridian the line at 0 degrees longitudean extra bit of the Moon's eastern limb is rotating into view, and when it moves above the equator, a bit of the far side beyond the south pole how to make a 3d model of solar eclipse visible.

Over students and teachers from across New England made the trip to see exhibits from the 7 different NASA missions and projects, demonstrations of space science concepts, and presentations from NASA scientists. It was a fun day of science and sports. One hundred Moon days. That's opportunities to observe changes from night to day, photograph the surface at different Sun angles, measure rising and falling temperatures, and study the way certain chemicals react to the daily light and temperature cycle, among other things.

The height of the Sun’s activity, known as solar maximum, is a time of solar storms: sunspots, solar flares and coronal mass ejections. These are caused by irregularities in the Sun's magnetic field and can release huge amounts of energy and particles, some of which reach us here on Earth. Introduction. The smallest planet in our solar system and nearest to the Sun, Mercury is only slightly larger than Earth's Moon. From the surface of Mercury, the Sun would appear more than three times as large as it does when viewed from Earth, and the sunlight would be as much as seven times brighter.
