Huge Canyon Spied on Pluto Moon Charon (Photos)

NASA's New Horizons spacecraft has spotted multiple craters and canyons on Pluto's big moon Charon, including one chasm that appears to be longer and deeper than Arizona's Grand Canyon, mission team members said. The photo also provides a good look at the 200-mile-wide (320 kilometers) dark patch at Charon's north pole, whose origin and nature remain mysterious. "This is the first clear evidence of faulting and surface disruption on Charon," William McKinnon, deputy lead scientist with New Horizons' geology and geophysics investigation team, said in a statement.

First Flybys: From Mercury to Pluto, a History of Solar System Surveys

Humanity is now just one day away from completing the initial reconnaissance of our local home in the universe. A journey nine years in the making, but which dates back more than a half century to our first encounter with another planet, NASA's New Horizons robotic spacecraft will fly by Pluto at 7:49 a.m. EDT (1149 GMT) on Tuesday (July 14), soaring past the final world in our classical solar system. The piano-sized probe, traveling at 30,800 mph (49,600 km/h) some 3 billion miles (5 billion kilometers) away from Earth, will come within 7,800 miles (12,500 km) of the dwarf planet, flying close enough to Pluto that if New Horizons was the same distance away from Earth, its camera would not only discern New York City, but also the ponds within Manhattan's Central Park.

Pluto at Last! NASA Spacecraft Arrives for Dwarf Planet Close-Up Tuesday

On Tuesday morning (July 14) — nine and a half years after launching, and a quarter-century after its mission began to take shape — NASA's New Horizons spacecraft will perform history's first flyby of Pluto. Closest approach will occur at 7:49 a.m. EDT (1149 GMT) Tuesday, when New Horizons zooms within just 7,800 miles (12,500 kilometers) of the dwarf planet's frigid surface. "It's thrilling," New Horizons principal investigator Alan Stern, of the Southwest Research Institute in Boulder, Colorado, told Space.com.

'Surfer's Waves' Found in Space

Researchers have discovered a breaking-wave pattern over the magnetosphere, the magnetic field that surrounds Earth. As seen in a new NASA image, these waves look similar to the ocean waves that surfers crave. Waves caused by a fast-moving fluid traveling over a slow-moving fluid are called Kelvin-Helmholtz waves.

Rare Harpy Eagle Chick Captured in New Pics

Harpy eagles nesting high above the understory of the Peruvian rainforest have been captured in a series of stunning new photos. Because the giant bird of prey lives in the darkest portions of the rainforest and hunts its quarry in dead silence, many Peruvian Amazon birders can go their entire lives without seeing one, said nature photographer Jeff Cremer, who photographed the eagles. Harpy eagles (Harpia harpyja) are imposing creatures.

Does Science Back Samsung's 80% Battery Boost Claim?

But could the new battery really boost battery life by that much? "I don't see it as a breakthrough technology," John B. Goodenough, a professor of mechanical engineering at the University of Texas, and the man who invented the lithium-ion battery, told Live Science. Lithium-ion batteries on the market today generate power by using lithium cobalt oxide as the positive terminal (the cathode), with carbon, usually in the form of graphite, as the negative terminal (the anode), and a lithium polymer compound as the electrolyte.

Ancient Native Americans May Have Had Pet Bobcat

A 2,000-year-old burial mound discovered in the area that's now Illinois contained the remains of a young bobcat, new research reveals. The ancient bobcat was wearing a special collar and was found in a ritual burial mound normally reserved for humans. "It really looked like it had been buried not because it was a feral accessory for a human, but because it was, in some way, kind of respected on its own," said study co-author Angela Perri, a zooarchaeologist at the Max Planck Institute for Evolutionary Anthropology in Germany.

For Girls, Mom's Physical Activity Level Sets the Example

The study of 40 girls ages 5 to 12 found that those with more active mothers were more physically active themselves. "Mothers are the first potentially powerful female role model for their daughters, and their daughters' beliefs and behaviors may stem directly from those of their mothers," said study co-author Alyce Barnes, an education researcher at the University of Newcastle in Australia. "Importantly, our study has shown that mothers have an important influence on their daughter's physical activity in relation to their parenting for physical activity and behaviors," Barnes said.

Supersonic Jet Could Fly People from NYC to London in 3 Hours

A new luxury jet could get you (and 17 of your closest friends) from New York to London in just 3 hours. Spike Aerospace's S-512 Supersonic Jet was introduced in 2013, but the Boston-based company recently announced a few exciting updates to the plane's design that could make it safer for jetsetters. Spike Aerospace's engineers claim the S-512 could reach a maximum speed of Mach 1.8 (1,370 mph, or 2,205 km/h), which is 1.8 times the speed of sound.

Why Do People Love Pluto?

Pluto — the once (and to some people, forever) ninth planet of the solar system — gets a lot of love from the general public. When Pluto's official status in the solar system was changed from "planet" to "dwarf planet," the public outcry was overwhelming. Neil deGrasse Tyson received angry letters from kids who disagreed with the decision, and the majority of people still think Pluto should retain "planet" status.

Pluto Is Larger Than Thought, Has Ice Cap, NASA Probe Reveals

With less than 24 hours to go before NASA's New Horizons probe makes its close flyby of Pluto, scientists are already learning more about the dwarf planet than ever before, including the fact that it is bigger than previously thought. New Horizons' latest views of Pluto have shown the dwarf planet to be 1,473 miles (2,370 kilometers) across, making it the largest body in the icy Kuiper Belt at the edge of the solar system. The observations also confirmed the presence of a polar ice cap on Pluto, and measured three of the dwarf planet's moons.

NASA's New Horizons probe finds Pluto is bigger than predicted

By Irene Klotz LAUREL, Md. (Reuters) - Mysterious Pluto looms large and turns out to be larger than expected as NASA's New Horizons spacecraft wraps up a nearly decade-long journey, with a close flyby on track for Tuesday, scientists said on Monday. The nuclear-powered probe was in position to pass dead center of a 60-by-90-mile (97-by-145 km) target zone between the orbits of Pluto and its primary moon, Charon, at 7:49 a.m. EDT on Tuesday, said managers at New Horizons mission control center, located at the Johns Hopkins University Applied Physics Laboratory outside of Baltimore. During the 30-minute dash past Pluto and its entourage of five moons, New Horizons will perform a carefully choreographed series of maneuvers to position its cameras and science instruments for hundreds of observations.

Lifting the Veil on Pluto's Atmosphere

Sophia Nasr is a science writer for Simulation Curriculum's free Pluto Safari app. You might guess that a small and distant world almost 40 times farther from the sun than the Earth is from the sun would not have an atmosphere, but in the case of Pluto, you'd be wrong. In fact, Pluto is a complex world, particularly when it comes to weather patterns.

New Horizons' Final Look at Pluto's Odd Dark Spots (Photo)

NASA's New Horizons spacecraft has captured its last and best photo of Pluto's four mysterious dark spots. The dark spots lie on Pluto's far side, which always faces the dwarf planet's largest moon, Charon. New Horizons won't be able to see the far side when it zooms through the Pluto system during its highly anticipated flyby on Tuesday morning (July 14), mission team members said.

Anxious Brains Are Inherited, Study Finds

The brain function that underlies anxiety and depression is inherited, a new study finds — but there is still plenty of space for experience and environment to reduce the risk of a full-blown mental disorder. Like humans, some young rhesus monkeys have what's called an "anxious temperament." Expose them to a mildly stressful situation, like being in a room with a stranger, and the monkeys will stop moving and stop vocalizing while their stress hormones skyrocket. Extremely shy children do the same, said Dr. Ned Kalin, a psychiatrist at the University of Wisconsin–Madison.

Rare Fossils of 400-Million-Year-Old Sea Creatures Uncovered

The Moroccan formation, known as the Fezouata Biota, holds some of the oldest known marine animals on Earth. A batch of horseshoe crab fossils show that the critters are about 25 million years older than was previously thought. What's more, the horseshoe crab fossils are incredibly complex, suggesting their ancestors evolved far earlier, said study lead researcher Peter Van Roy, a paleontologist at Yale University.

'Alice in Wonderland Syndrome' Caused by Acid Flashback

Lewis Carroll's delightful children's novel "Alice's Adventures in Wonderland" turns 150 this year. This syndrome, named in 1955 by British psychiatrist John Todd, has long been known to co-occur with some migraines. These perceptual distortions are the hallmark of Alice in Wonderland syndrome, so dubbed because Alice experiences some very similar symptoms during her journey through Wonderland in Lewis Carroll's tale.

Spotted face of distant Pluto coming into focus

By Irene Klotz CAPE CANAVERAL, Fla (Reuters) - NASA's New Horizons spacecraft is closing fast on an unexpectedly spotted Pluto, the most distant planetary body ever explored. From New Horizon's position more than 3 billion miles (4.88 billion km) from Earth, radio signals, traveling at the speed of light, take nearly four and a half hours to reach the ground. Not that the probe, which has been traveling toward Pluto for more than nine years, is currently spending much time relaying back pictures and data from its seven science instruments.

Comet team says lander gets back in touch with new data

European scientists received data from the newly revived comet lander Philae on Thursday night, a boost to the team as they try to establish a secure line of communication for their historic scientific experiments on the surface of the comet. The European Space Agency landed Philae on comet 67P/Churyumov-Gerasimenko in November, but the lander bounced and landed in a position too shadowy to power its solar panels. As the comet approached the sun, the lander surprised scientists by waking up and sending signals to Earth on June 13.

A Brief History of Pluto Viewing: From Its Discovery to New Horizons Flyby

Pluto has captured people's imagination for nearly a century. The frigid world at the solar system's outer reaches that was discovered in 1930 remains mysterious to this day: because Pluto is relatively small and so far away, telescopes on and near Earth haven't been able to take its measure. NASA's New Horizons spacecraft is already getting good looks at Pluto, and will return history's first up-close photos of the dwarf planet during a July 14 flyby.
