    Washington Post ^ | September 3 | Joel Achenbach
    The paper ... noted that a number of large, very remote objects share a similar orbital angle. That's suspicious if you're an astronomer expecting to see a random distribution of objects. The key orbital feature is known, rather obtusely, as the “argument of perihelion.” We're not shy of complicated orbital concepts (we try to toss around the phrase "obliquity of the ecliptic" whenever possible), but this one is not very easy to explain. "The argument of perihelion is the angle at which an object comes to perihelion with respect to the ecliptic plane," Sheppard said in an e-mail. Mike Brown,...

    According to a Tuesday piece in Motherboard, Noam Chomsky, a philosopher and political commentator, and Lawrence Krauss, a physicist and cosmologist, had a public dialogue about space exploration. Being both men of the far left, they concluded that space travel should be best left to robots and conducted by governments. The conclusions are the exact opposite of what the prevailing trends are in space policy.

    Asteroids and comets have a few things in common. They are both celestial bodies orbiting our Sun, and they both can have unusual orbits, sometimes straying close to Earth or the other planets. They are both “leftovers” — made from materials from the formation of our Solar System 4.5 billion years ago. But there are a few notable differences between these two objects, as well. The biggest difference between comets and asteroids, however, is what they are made of. While asteroids consist of metals and rocky material, comets are made up of ice, dust, rocky materials and organic compounds. When...

    The comet 67P/Churyumov-Gerasimenko may actually be two objects stitched together. New images from ESA's Rosetta spacecraft show an odd constriction near the middle of the comet, suggesting that two clumps of matter may have merged in what scientists call a contact binary. The conclusions are preliminary, as Rosetta was still roughly 12,000 kilometers away from the comet when the images were taken. The comet could also have had a more regular single shape with parts carved out through impacts or ice melting as the object circled the sun, mission scientists say. They will have more details about the comet's...

"How many chances do you get to fly into the very heart of the asteroid belt?" said Keyur Patel, Dawn project manager at NASA's Jet Propulsion Laboratory, Pasadena, Calif....

    LOS ANGELES - NASA decided Monday to restart a mission to explore two of the solar system's largest asteroids, just weeks after the project was killed because of budget woes. The space agency earlier this month scrapped the $446 million Dawn mission to orbit the asteroids Ceres and Vesta, nearly a half year after it was put on hold because of cost overruns and technical problems. NASA decided to review the cancellation after the Jet Propulsion Laboratory, which managed the mission, made an appeal. "Our review determined the project team has made substantive progress on many of this mission's technical...

    LOS ANGELES - In an unusual move, NASA is reviewing a recent decision by an agency head to scrap a mission to orbit two asteroids. The Dawn project was canceled on March 2, five months after it was put on standdown because of cost overruns and technical problems. NASA's unusual step to review Dawn's termination came after the Jet Propulsion Laboratory in Pasadena, which manages the mission, presented new evidence, the space agency said in a statement. It's the first time in recent memory that a NASA center has challenged a headquarters decision on a canceled mission, said NASA spokeswoman...

    Icy world found inside asteroid Ron Cowen New observations of Ceres, the largest known asteroid, suggest that frozen water may account for as much as 25 percent of its interior. If this is true, the volume of ice on Ceres would be greater than that of all the fresh water on Earth. CERES SERIES. This sequence of Hubble images reveals a bright spot of unknown origin on Ceres during a quarter-turn of the asteroid's 9-hour rotation. Thomas, et al., NASA The evidence comes from Hubble Space Telescope images showing that the 930-kilometer-wide asteroid is smooth and almost perfectly round. Simulations...

    Can you imagine the devastation that would be caused if a massive wall of water several hundred feet high slammed into Florida at more than 100 miles an hour? To many people such a scenario is impossible, but that is what people living along the Indian Ocean thought before the 2004 tsunami and that is what people living in Japan thought before the 2011 tsunami. Throughout history, giant tsunamis have been relatively rare events, but they do happen. Scientists tell us that a mega-tsunami can race across the open ocean at up to 500 miles an hour, and when they...

    Beyond Neptune lies a reservoir of... icy debris left to roam the solar system's dim outer limits having never coalesced into planets... Named for astronomer Gerard Kuiper, who in 1951 predicted the existence of this 3-billion-kilometer-wide swath of icy chunks, the Kuiper belt didn't begin to reveal itself to observers until 1992. Since then, researchers have found more than a thousand bodies filling a doughnut-shaped belt, which extends 30 to about 50 astronomical units from the sun. One astronomical unit is the average distance between the Earth and sun... The puffed-up, elongated orbits and present-day sparseness of the belt all...

    Many of the primitive bodies wandering the asteroid belt between Mars and Jupiter are former comets, tossed out of orbit by a brutal ballet between the giant outer planets, said a team of astrophysicists. A commonly accepted theory is that the asteroid belt is the rubble left over from a "proto-planetary disk," the dense ring of gas that surrounds a new-born star. But the orbiting rocks have long been a source of deep curiosity. They are remarkably varied, ranging from mixtures of ice and rock to igneous rocks, which implies they have jumbled origins. The answer to the mystery, according...

    An asteroid at least the size of a 60-story building will make a distant flyby of Earth this week, and you watch astronomers track the space rock tonight (March 9) in a live webcast, weather permitting. The asteroid poses no threat to Earth. The online Slooh community observatory will host the free webcast at 10 p.m. EDT (0200 GMT) to track asteroid 2014 CU13, a space rock about 623 feet (190 meters) wide discovered on Feb. 11 that will pass Earth at a range of about eight times the distance between Earth and the moon on Tuesday (March 11).

    The Hubble Space Telescope spotted something no one had ever seen before: an asteroid shattering into as many as 10 smaller pieces. “This is a really bizarre thing to observe–we’ve never seen anything like this,” Jessica Agarwal of the Max Planck Institute for Solar System Research in Germany said in a statement. ... Asteroid P/2013 R3 was discovered last September 15 by the Catalina and Pan-STARRS sky surveys. At first, all astronomers saw was a faint, fuzzy object. Then, a couple of weeks later, the great Keck Telescope in Hawaii took a closer look and saw not one but three...

    And it's actually (relatively) nearby. This is poor, unfortunate Ceres. Discovered in 1801, it was at first called a planet, then soon classified as an asteroid, and recently as a dwarf planet, not quite qualifying for real planet status despite residing in the solar system's asteroid belt. But now it can feel special: the Herschel Telescope has, the for the first time, detected water on the lil' planet--probably a whole lot of it, too. The telescope, using infrared vision, detected a signature of water vapor from Ceres. The researchers think when the 590-mile-wide Ceres moves closer to the sun, part...

    Looking for something off of the beaten celestial path to observe? The coming weeks will offer telescope users a rare chance to catch a well known asteroid, as it puts on its best show for over two decades. Over the coming weeks, 2 Pallas, one of the “big four” asteroids – or do you say minor/dwarf planet/planetoid? – reaches a favorable observing point known as opposition. Gliding northward through the constellations of Hydra and Sextans through February and March 2014, 2 Pallas presents a favorable binocular challenge for both northern and southern hemisphere observers as it rises to the east...
