Using a new process in planetary formation modeling, where planets grow from tiny bodies called "pebbles," Southwest Research Institute scientists can explain why Mars is so much smaller than Earth. This same process also explains the rapid formation of the gas giants Jupiter and Saturn, as reported earlier this year. "This numerical simulation actually reproduces the structure of the inner solar system, with Earth, Venus, and a smaller Mars," said Hal Levison, an Institute scientist at the SwRI Planetary Science Directorate. He is the first author of a new paper published in the Proceedings of the National Academy of Sciences...

Explanation: It was visible around the world. The sunset conjunction of Jupiter and Venus in 2012 was visible almost no matter where you lived on Earth. Anyone on the planet with a clear western horizon at sunset could see them. Pictured above in 2012, a creative photographer traveled away from the town lights of Szubin, Poland to image a near closest approach of the two planets. The bright planets were separated only by three degrees and his daughter striking a humorous pose. A faint red sunset still glowed in the background. Jupiter and Venus will be at it again this...

Uranus, which takes its name from the Greek God of the sky, is a gas giant and the seventh planet from our Sun. It is also the third largest planet in our Solar System, ranking behind Jupiter and Saturn. Like its fellow gas giants, it has many moons, a ring system, and is primarily composed of gases that are believed to surround a solid core. Though it can be seen with the naked eye, the realization that Uranus is a planet was a relatively recent one. Though there are indications that it was spotted several times over the course of...

Gina McCarthy, President Obama’s choice to replace Lisa Jackson at the Environmental Protection Agency, has been chastised for having lied to Congress, in claiming that EPA did not use “dangerous manmade climate change” to justify new 54.5 mpg standards for cars and light trucks. She’s also been implicated in the agency’s practice of using fake emails to hide questionable dealings and activities. These issues highlight attitudes toward ethics, law and public policy that prevail at EPA and too many other government agencies. However, that attention should not distract from other important matters. Ms. McCarthy may be the worst of the...

It was the end of the road for a Casanova who has swindled about 20 women of their money and jewellery when he was arrested by police. The 34-year-old man was believed to have been involved in 20 fraud cases amounting to about RM155,000 (S$55,000). [US$40,600] Identifying himself as Aidid Iskandar, Afzan Iskandar and Hafis, the man would approach his victims on Facebook and sweet-talk them into believing he was sincere. The father-of-three is said to have cheated about 20 women between the ages of 28 and 38 of their cash and jewellery in two years. Brickfields police chief Asst...

California Gov says yes to poisoning more children with mercury and aluminum in manditory vaccines,” he said. “This corporate fascist must be stopped.” He went on to say the U.S. Centers for Disease Control and Prevention is corrupt because they “can’t solve a problem they helped start.” Carrey, who lives in Los Angeles, said he does not oppose vaccines, but is rather “anti-neurotoxin.” He believes vaccines should be free of chemicals and certain compounds, such as mercury and thimerosal. “All we are saying is, 'Take the neurotoxins out of the vaccines.' Make them toxin free. History will show that that...

The war has been waged on several fronts for nearly a decade, and the aggressors are poised to declare victory over the wounded U.S. coal industry. After powering the Industrial Revolution and helping to turn the U.S. into the world’s top economic power, coal now seems to be drowning in what environmentalists call a “deadly cocktail” — a rabid, politically potent anti-fossil fuels movement, the rise of cheap, abundant, relatively clean domestic natural gas and an Obama administration that freely admits it wants to decrease coal use in America through a host of new rules. That near-perfect storm is taking...

THE $90 million search for MH370 has discovered “man made objects” almost four kilometres under the surface of the southern Indian Ocean, but they are not the missing Boeing 777. Instead the debris is thought to be from an ancient shipwreck, comprising an anchor and other items. Australian Transport Safety Bureau Operational Search Director Peter Foley said they were “obviously disappointed” the discovery was not the missing aircraft.

Before the spacecraft ended its mission, it captured almost 100,000 images of the planet mapping its gravitational field. As scientists study the data, they found that it ages about 4 billion years old. Furthermore, the spacecraft was able to collect sufficient information for scientists to conclude that Mercury’s crust is thicker in low latitudes and thinner at both poles. This kind of distribution highly suggests that the planet is made of liquid or molten outer core, which comprises 85% Mercury’s radius and bigger than Earth’s core. Also, the layer below the crust of the planet is made up of liquid...

Explanation: What's that under the surface of Mercury? The robotic MESSENGER spacecraft that had been orbiting planet Mercury for the past four years had been transmitting its data back to Earth with radio waves of very precise energy. The planet's gravity, however, slightly changed this energy when measured on Earth, which enabled the reconstruction of a gravity map of unprecedented precision. Here gravitational anomalies are shown in false-color, superposed on an image of the planet's cratered surface. Red hues indicate areas of slightly higher gravity, which in turn indicates areas that must have unusually dense matter under the surface. The...

Explanation: The first to orbit Mercury, the MESSENGER spacecraft came to rest on this region of Mercury's surface yesterday. Constructed from MESSENGER image and laser altimeter data, the scene looks north over the northeastern rim of the broad, lava filled Shakespeare basin. The large, 48 kilometer (30 mile) wide crater Janacek is near the upper left edge. Terrain height is color coded with red regions about 3 kilometers above blue ones. MESSENGER'S final orbit was predicted to end near the center, with the spacecraft impacting the surface at nearly 4 kilometers per second (over 87,000 miles per hour) and creating...

At 8.45 on the morning of 15 April 136 BC, Babylon was plunged into darkness when the Moon passed in front of the Sun. An astrologer, who recorded the details in cuneiform characters on a clay tablet, wrote: "At 24 degrees after sunrise-a solar eclipse. When it began on the southwest side, Venus, Mercury and the normal stars were visible. Jupiter and Mars, which were in their period of disappearance, became visible. The Sun threw off the shadow from southwest to northeast." If present-day astronomers use a computer to run the movements of the Earth, Moon and Sun backwards...

A Mexican archeologist hunting for a royal tomb in a deep, dark tunnel beneath a towering pre-Aztec pyramid has made a discovery that may have brought him a step closer: liquid mercury. In the bowels of Teotihuacan, a mysterious ancient city that was once the largest in the Americas, Sergio Gomez this month found "large quantities" of the silvery metal in a chamber at the end of a sacred tunnel sealed for nearly 1,800 years. "It's something that completely surprised us," Gomez said at the entrance to the tunnel below Teotihuacan's Pyramid of the Plumed Serpent, about 30 miles (50...

Archaeologists have found the remains of an ancient imperial palace near the tomb of emperor Qin Shi Huang, home of the famous terracotta army, China's state media reported on Sunday. The palace is the largest complex discovered so far in the emperor's sprawling 22 square-mile (56 square-km) second-century BC mausoleum, which lies on the outskirts of Xi'an, an ancient capital city in central China, an associate researcher at the Shaanxi provincial institute of archaeology told China's official news wire Xinhua. It is an estimated 690 metres long and 250 metres wide – about a quarter of the size of the...

Terracotta army has egg on its face Monday, 21 April 2008 Jennifer Viegasv Discovery News Soldiers of China's terracotta army were once brightly painted, then preserved with an egg coating (Source: Reuters/Philippe Wojazer) China's terracotta army, a collection of 7000 soldier and horse figures in the mausoleum of the country's first emperor, was covered with beaten egg when it was made, scientists say. According to German and Italian chemists who have analysed samples from several figurines, the egg was as a binder for colourful paints, which went over a layer of lacquer. "Egg paint is normally very stable, and not...

5 guesses on Emperor Qin Shihuang's tomb Qin Shihuang holds a central place in Chinese history for being the first emperor who united the country. He is also well known for his part in the construction of the spectacular Great Wall and his splendid terracotta army. To ensure his rule in the afterlife, this emperor commanded more than 700,000 conscripts from all parts of the country to build him a grand mausoleum as luxurious as any of the palaces he had in mortal life. Legend says that numerous treasures were placed in the tomb. As time passed, no one knew...

Mysterious building discovered in emperor's tomb Last Updated(Beijing Time):2007-07-01 10:33 Chinese archaeologists said that after five years of research they have confirmed that there is a 30-meter-high building buried in the tomb of Qinshihuang, Chinese first emperor more than 2,000 years ago. The building, buried in the 51-meter-high, pyramid-like earth above the tomb's main body underground, has four surrounding stair-like walls and each wall with nine steps of platforms, said Duan Qingbo, a researcher with Shaanxi Institute of Archaeology. The whole building were buried under the earth, which made it difficult for researchers to get a complete picture of it,...

XIAN, China: The tomb of China's first emperor is potentially one of the most spectacular on Earth, but a heated debate is developing over whether to excavate it at all. Chinese archaeologists have expressed concern that they do not currently have the expertise to properly preserve what they find inside the tomb - located in China's central province of Shaanxi – but new technologies may be closing that gap. Qinshi Huang's enormous tomb complex is the home of Xian's famed terracotta warriors; 8,000 life-size figures that were discovered by accident in 1974. The tomb itself, though, has not yet been...
