    NASA ^ | August 14, 2014 | (see photo credit)
    Explanation: Big, bright, and beautiful, a Full Moon near perigee, the closest point in its elliptical orbit around our fair planet, rose on August 10. This remarkable picture records the scene with a dreamlike quality from the east coast of the United States. The picture is actually a composite of 10 digital frames made with exposures from 1/500th second to 1 second long, preserving contrast and detail over a much wider than normal range of brightness. At a perigee distance of a mere 356,896 kilometers, August's Full Moon was the closest, and so the largest and most super, of the...

    Now here’s something I guarantee you’ve never seen before: a video of the dwarf planet Pluto and its largest moon Charon showing the two distinctly separate worlds actually in motion around each other! Captured by the steadily-approaching New Horizons spacecraft from July 19–24, the 12 images that comprise this animation were acquired with the Long Range Reconnaissance Imager (LORRI) instrument from distances of 267 million to 262 million miles (429 million to 422 million km) and show nearly a full orbital rotation. ... Pluto and Charon are seen circling a central gravitational point known as the barycenter, which accounts for...

    July 20, 2014, will mark the 45th anniversary of the Apollo 11 landing on the Moon, the first time humans had ever set foot on another part of the universe. Besides being a tremendous scientific achievement, it was also an important political statement, a battle victory for the US and the West over the Soviet Union and the Communists in the Cold War, a battle known as the Space Race. During World War II the technological leaders in rocket science were the Germans. After the war, with the Cold War underway, the US and the USSR each tried to...

    I vividly recall being in the living room with my family watching tv in 1969 as the American Astronauts walked on the moon. The pictures were fuzzy, black and white, somewhat indistinct. It almost resembled an Ultrasound image an expectant mother would see. We were thrilled to be part of a country, a culture so advanced as to put men on the moon and later, to bring them back safely to earth. We had completely one-upped communist Russia! Sputnik was a very important step in space exploration. Quite significant back in 1957, but that was a long time ago, back...

    The year was 1969. The turbulent time in America saw troops fighting in Vietnam, and a nation dealing with the assassinations of President John F. Kennedy, killed in 1963, and Robert Kennedy and Martin Luther King Jr., both murdered in 1968. Then came that one small step. Forty-five years ago today, 500 million people around the world witnessed American astronauts Neil Armstrong, Edwin "Buzz" Aldrin and Michael Collins as they embarked on the Apollo 11 mission to the moon. Apollo 11 landed on the moon on July 20, 1969, and six hours later Armstrong was the first man to step...

    Explanation: What happened to half of Saturn? Nothing other than Earth's Moon getting in the way. As pictured above on the far right, Saturn is partly eclipsed by a dark edge of a Moon itself only partly illuminated by the Sun. This year the orbits of the Moon and Saturn have led to an unusually high number of alignments of the ringed giant behind Earth's largest satellite. Technically termed an occultation, the above image captured one such photogenic juxtaposition from Buenos Aires, Argentina that occurred early last week. Visible to the unaided eye but best viewed with binoculars, there are...

    The Guardian Liberty Voice ^ | June 28, 2014 | Gregory Baskin
    A team from Harvard University presented a study this month that remnants from an ancient Earth exists, right now, inside contemporary Earth. The group believes that their comparisons of isotopic ratios of noble gases from materials deep inside Earth with those near the surface provide testimony that the deep-down material is actually from the Earth that existed before its massive collision with another planet. That immense impact – the largest in geologic history – is what many believe led to creation of the Moon. The currently favored theory about how the Moon originated says that it was formed 4.5 billion...

    Creation stories tend to be outlandish, in keeping with the near impossibility of explaining why the world is the way it is — from the week-long labours of the Old Testament God, to the eternal cycles of the Hindu creator Brahma, to Raven’s metaphysical trickery in Pacific Northwest First Nations tradition. Fanciful as they are, however, these myths have nothing on modern science, whose creation story — which already involves a mysterious Big Bang, perhaps one of many creations ex nihilo in infinite succession — this week got even weirder. At a geophysics conference in California, a series of discoveries...

    Explanation: The Sun set on Friday the 13th as a full Honey Moon rose, captured in this well-planned time-lapse sequence. Lisbon, Portugal's Christ the King monument is in the foreground, about 6 kilometers distant from camera and telephoto lens. During the days surrounding today's solstice (June 21, 10:51 UT) the Sun follows its highest arc through northern hemisphere skies as it travels along the ecliptic plane. At night the ecliptic plane is low, and the Full Moon's path close to the ecliptic was also low, the rising Moon separating more slowly from the distant horizon. Northern moon watchers were likely...

    A man was arrested by Prescott Valley police after he shot his handgun in a residence and claimed he was shooting at the moon. On Friday, a 49-year-old woman called police because her boyfriend had fired shots from a handgun and was still armed at the time, according to the Prescott Valley Police Department. Officers arrived at a residence near Robert Road and Loos Drive where they confronted 39-year-old Cameron Read. Read initially refused to leave the residence, but eventually exited and resisted arrest before being taken into custody by force, according to police. The victims told police Read had...

    Last week, the engineering arm of the European Space Agency confirmed that it has been commissioned to test the space-hardiness of the capsule that would contain the Torah, the Post reported. The capsule must be designed to protect the sacred text from the moon’s harsh radiation and temperature changes for at least 10,000 years. The moon lacks an atmosphere to trap heat, and the surface temperatures can rocket to a daytime high of about 253 degrees and plunge to 279 degrees below zero at night.

    A new analysis of lunar rocks brought home by Apollo mission astronauts has shed fresh light on the violent birth of the moon. Researchers in Germany have found small but distinctive chemical signatures that suggest the moon formed when a giant planetary body slammed into the early Earth 4.5bn years ago. Scientists have several theories for how the moon may have formed, but the "giant impact hypothesis" has been the leading explanation for some time. A cataclysmic impact between the Earth and a Mars-sized planet, known as Theia, would have scattered rock and dust from both bodies out into space,...

    Nature of mysterious hot spot revealed by “photogeology” Analysis of new images of a curious “hot spot” on the far side of the Moon reveal it to be a small volcanic province created by the upwelling of silicic magma. The unusual location of the province and the surprising composition of the lava that formed it offer tantalizing clues to the Moon’s thermal history. The hot spot is a concentration of a radioactive element thorium sitting between the very large and ancient impact craters Compton and Belkovich that was first detected by Lunar Prospector’s gamma-ray spectrometer in 1998. The Compton-Belkovich Thorium...

    Explanation: Why would a bright full Moon suddenly become dark? Because it entered the shadow of the Earth. Almost two weeks ago this exact event happened as the Moon underwent a total lunar eclipse. That eclipse, visible from the half of the Earth then facing the Moon, was captured in numerous spectacular photographs and is depicted in the above time lapse video covering about an hour. The above video, recorded from Mt. Lemmon Sky Center in Arizona, USA, keeps the Earth shadow centered and shows the Moon moving through it from west to east.

    With the glow of Earth well-hidden, any dust in the moon’s scant atmosphere around the time of orbital sunrise should become visible. Scientists also expected to see the softly luminous glow of the zodiacal light, an extensive cloud of comet and asteroid dust concentrated in the flat plane of the solar system. The zodiacal light gets its name from the zodiac, that familiar band of constellations the planets pass through as they orbit the sun. Back on Earth, the zodiacal light looks like a big thumb of light standing up from the western horizon a couple hours after sunset in...

    Explanation: A beautiful, reddened Moon slid through dark skies on April 15, completely immersed in Earth's shadow for well over an hour. It was the year's first total lunar eclipse and was widely enjoyed over the planet's Western Hemisphere. Seen from the Caribbean island of Barbados, the dimmed lunar disk is captured during totality in this colorful skyview. The dark Moon's red color contrasts nicely with bright bluish star Spica, alpha star of the constellation Virgo, posing only about two degrees away. Brighter than Spica and about 10 degrees from the Moon on the right, Mars is near opposition and...

    Explanation: Tidally locked in synchronous rotation, the Moon always presents its familiar nearside to denizens of planet Earth. From lunar orbit, the Moon's farside can become familiar, though. In fact this sharp picture, a mosaic from the Lunar Reconnaissance Orbiter's wide angle camera, is centered on the lunar farside. Part of a global mosaic of over 15,000 images acquired between November 2009 and February 2011, the highest resolution version shows features at a scale of 100 meters per pixel. Surprisingly, the rough and battered surface of the farside looks very different from the nearside covered with smooth dark lunar maria....

    With the help of a self-developed computer model, a team of researchers forecasted how apatite would have crystalized from cooling bodies of lunar magma early in the Moon's history. The model proved that the abnormally hydrogen-rich apatite crystals seen in many Moon rock samples may not have developed within a water-rich environment as previously though. "The mineral apatite is the most widely used method for estimating the amount of water in lunar rocks, but it cannot be trusted," said Jeremy Boyce of the UCLA Department of Earth, Planetary and Space Sciences in a statement.

Enter Tesla's GigaFactory, aiming by 2020 for annual production of 500,000 lithium-ion battery packs. Under one roof — a very large one, at 10 million square feet — Tesla will “manage everything from processing raw materials to the assembly of the batteries.” All of which begs the question: Where is all that lithium going to come from?...

    New Haven, Conn. — The Gondwana supercontinent underwent a 60-degree rotation across Earth’s surface during the Early Cambrian period, according to new evidence uncovered by a team of Yale University geologists. Gondwana made up the southern half of Pangaea, the giant supercontinent that constituted the Earth’s landmass before it broke up into the separate continents we see today. The study, which appears in the August issue of the journal Geology, has implications for the environmental conditions that existed at a crucial period in Earth’s evolutionary history called the Cambrian explosion, when most of the major groups of complex animals rapidly...

    Skywatchers have been trying to gauge the sun-Earth distance for thousands of years. In the third century BC, Aristarchus of Samos, notable as the first to argue for a heliocentric solar system, estimated the sun to be 20 times farther away than the moon. It wasn't his best work, as the real factor is more like 400. By the late 20th century, astronomers had a much better grip on this fundamental cosmic metric -- what came to be called the astronomical unit. In fact, thanks to radar beams pinging off various solar-system bodies and to tracking of interplanetary spacecraft, the...

    University of Arizona scientists have uncovered a curious case of missing asteroids. The main asteroid belt is a zone containing millions of rocky objects between the orbits of Mars and Jupiter. The scientists find that there ought to be more asteroids there than researchers observe. The missing asteroids may be evidence of an event that took place about 4 billion years ago, when the solar system's giant planets migrated to their present locations. UA planetary sciences graduate student David A. Minton and UA planetary sciences professor Renu Malhotra say missing asteroids is an important piece of evidence to support an...

    Evidence that water came to Earth during its formation from cosmic dust, rather than following later in asteroids, has been shown by a group of international scientists. The origin of the abundant levels of water on Earth has long been debated with the main differences in the theories being the nature of the material that carries the water, and whether the water came during or after planet formation. Now, Nora de Leeuw at University College London, UK, and colleagues have used molecular-level calculations to prove that dissociative chemisorption of water onto the surface of olivine rich minerals, such as forsterite,...

A Scottish printmaker has released a series of works that publicize a fact known to astronauts for decades: The moon smells like gunpowder. Apprentice printer Sue Corke worked with flavorist Steven Pearce of Omega Ingredients and Apollo 16 astronaut Charles M. Duke Jr. to create "scratch-and-sniff" moon prints. NASA has known since the 1970s about the gunpowder-like odor of Earth's natural satellite. Even though there's no air on the moon, one moonwalker, Apollo 14 lunar module pilot Edgar D. Mitchell, confirmed to AOL News that the moon smells...

    An analysis of sediments brought back by the Apollo 17 mission has shown that the Moon's interior holds far more water than previously thought.The analysis, reported in Science, has looked at pockets of volcanic material locked within tiny glass beads. It found 100 times more water in the beads than has been measured before, and suggests that the Moon once held a Caribbean Sea-sized volume of water. The find also casts doubt on aspects of theories of how the Moon first formed. A series of studies in recent years has only served to increase the amount of water thought to...

    Early in the evening of June 18, 1178, a group of men near Canterbury, England, stood admiring the sliver of a new moon hanging low in the west. In terms they later described to a monk who recorded their sighting, "Suddenly a flaming torch sprang from the moon, spewing fire, hot coals and sparks." In continuing their description of the event, they reported that "The moon writhed like a wounded snake and finally took on a blackish appearance"... [P]lanetary scientist Jack Hartung of the State University of New York... gathered enough clues to suggest that a large asteroid... might have...

    STEREO Hunts for Remains of an Ancient Planet near Earth April 9, 2009: NASA's twin STEREO probes are entering a mysterious region of space to look for remains of an ancient planet which once orbited the Sun not far from Earth. If they find anything, it could solve a major puzzle--the origin of the Moon. The name of the planet is Theia," says Mike Kaiser, STEREO project scientist at the Goddard Space Flight Center. "It's a hypothetical world. We've never actually seen it, but some researchers believe it existed 4.5 billion years ago—and that it collided with Earth to form...

    Clara Moskowitz The solar system might once have had another planet named Theia, which may have helped create our own planet's moon. Now two spacecrafts are heading out to search for leftovers from this rumored sibling, which would have been destroyed when the solar system was still young. "It's a hypothetical world. We've never actually seen it, but some researchers believe it existed 4.5 billion years ago — and that it collided with Earth to form the moon," said Mike Kaiser, a NASA scientist at the Goddard Space Flight Center in Maryland...

    Line up Mercury, Venus, Earth and Mars according to their distance from the sun and you'll see their size distribution is close to symmetrical, with the two largest planets between the two smallest. That would be no coincidence -- if the pattern emerged from a debris ring around the sun. Brad Hansen of the University of California, Los Angeles, built a numerical simulation to explore how a ring of rocky material in the early solar system could have evolved into the planets. He found that two larger planets typically form near the inner and outer edges of the ring, corresponding...

    Neptune's largest moon, Triton, was originally a member of a duo orbiting the Sun but was kidnapped during a close encounter with Neptune, a new model suggests. Triton is unique among large moons in that it orbits Neptune in a direction opposite to the planet's rotation, which long ago led scientists to speculate that the moon originally orbited the Sun. But until now, no convincing theory for how Triton paired with Neptune existed. Gravity might have pulled Triton away from its companion to make it an orbiting satellite of Neptune, researchers report in a new study published in the May...

    Speranza points out another difficulty with the impact-origins theory. Large blocks of limestone sit within the boundaries of the Sirente "crater." Such limestone would not have survived an impact. So if Ormö's theory is correct, one must surmise that somebody set these giant chunks of rock in place since the crater formed. To Speranza, that just didn't make sense. Speranza and colleagues further argue that Ormö's radiocarbon dating gave one age for the main feature (placing it in the 4th or 5th century a.d.) and a completely different age for a nearby "crater" called C9, a date in the 3rd...

    Deep down, the moon may be more like Earth than scientists ever thought. A new moon-rock study suggests the satellite has an iron core... The moon's core could be a clue to its ancient origins, which have long puzzled astronomers. "Our moon is too big to be a moon," Taylor said. "It's huge compared to the moons we see around other planets, so it has always been suspected that there was something strange in its origin." ...Rock samples from NASA's Apollo 15 and Apollo 17 moon missions of the early 1970s have now shed more light on the moon's origins,...

    The crash may also someday create the biggest and brightest comet of all time. Astronomer Michael Brown of the California Institute of Technology found the five fragments while studying the Kuiper belt, located in the solar system's outermost reaches. The fragments resemble 2003 EL61, the Kuiper belt's mysterious third largest object, suggesting all six bodies were formed in a single violent crash, Brown said... Measuring about 930 miles (1,500 kilometers) across, 2003 EL61 had puzzled scientists ever since its discovery, because it's oblong and spins end-over-end so fast that it completes a full revolution every four hours... 2003 EL61 is...
