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...

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...

In 2008, a group of astronomers led by Alex Parker did a study of the size distribution of asteroid families using data from the Sloan Digital Sky Survey. Asteroid families often have distinctive optical colors, the team said, and they were able to offer an improved way to separate out the family members into their colors. This resultant animation put together just this week by Parker shows the orbital motions of over 100,000 asteroids, with colors illustrating the compositional diversity and relative sizes of the asteroids. All main-belt asteroids and Trojan asteroids with orbits known to high precision are shown...

Asteroid to hurtle past the Earth at 27,000 mph A giant "potentially hazardous" asteroid more than three times the size of a football pitch is to hurtle past the Earth at more than 27,000 miles per hour Although the speeding chunk of rock, named 2000 EM26, will be 1.6 million miles away it still represents a close shave for our planet in astronomical terms ‘potentially hazardous’ asteroid which is three times the size of a football pitch and travelling at 27,000 miles an hour will pass close to Earth on Monday night. Although the speeding chunk of rock – named...

Near-Earth asteroid 2000 EM26 poses no threat of actually hitting the planet, but the online Slooh Space Camera will track the asteroid as it passes by Earth on Monday. The live Slooh webcast will start at 9 p.m. EST (0200 Feb. 18 GMT), and you can also watch the webcast directly through the Slooh website. You can also watch the asteroid broadcast live on Space.com. Scientists estimate that 2000 EM26 is about 885 feet in diameter, and it is whizzing through the solar system at a break-neck 27,000 mph, according to Slooh. During its closest approach, the asteroid will fly...

The results of a workshop to find the best ways to find, track and deflect asteroids headed for Earth were released by NASA on Friday (Feb. 7). NASA's Asteroid Initiative, started in 2013, includes a mission to capture a small near-Earth asteroid and drag it into a stable orbit around the moon, and a challenge to devise the best ideas for detecting and defending against potentially dangerous asteroids. The agency put out a request for information to refine the objectives of the Asteroid Initiative, to generate other mission concepts and increase participation in the mission and planetary defense. NASA received...

It is a commentary on how adrift NASA space policy is when one considers that four years after President Obama made his "we choose not to return to the moon" speech that the space agency may be pivoting back to the moon. Paul Spudis, a planetary geologist and return to the moon advocate, has read the tea leaves and has seen the first, tentative steps toward a pivot back to the moon. Elon Musk, the space entrepreneur and political ally of Barack Obama, has recently conceded that expeditions to the moon would be useful. NASA is partnering with private companies,...

(VIDEO-AT-LINK)With NASA reporting a “potentially hazardous” asteroid nearly half-a-mile wide possibly heading toward earth, and some upstate New Yorkers claiming they experienced a loud boom and a bright light in the sky last night caused by a meteor, a doctors’ organization is offering some timely advice: Just as when the American populace first prepared for the possibility of a nuclear blast, a person’s best option for surviving a meteor strike is the same “duck and cover” created during the 1940s and ’50s when nuclear weaponry was still in its infancy. The warning comes from Physicians for Civil Defense, which issued...

It is frustrating, at a time when other nations are in ascendancy in space, that the administration of U.S. President Barack Obama seems committed to undermining the nation's own solar system exploration program. The Obama administration cut NASA's planetary-sciences budget by 20 percent in 2013. It has taken the National Research Council's (NRC) recommendations for prioritizing planetary investments in bad economic times and turned those recommendations upside down. The administration continues to favor large, directed projects at the expense of programs and missions that are openly competed.

Discretionary Spending--Option 11 Eliminate Human Space Exploration Programs The National Aeronautics and Space Administration's (NASA's) Human Exploration and Operations programs focus on developing systems and capabilities required to explore deep space while continuing operations in low- Earth orbit. The exploration programs fund research and development of the next generation of systems for deep space exploration and provide technical and financial support to the commercial space industry. Complementing those efforts, NASA's space operations programs involve operating in low-Earth orbit, most notably using the International Space Station, as well as providing space communications capabilities. This option would terminate NASA's human space exploration...

| The discovery of mysterious rocks on the brightest large asteroid in the solar system, Vesta, deepens the mystery surrounding the huge object's origins, researchers say. Vesta is the second-largest asteroid in the solar system. The 330-mile-wide (530-kilometer) protoplanet is also the brightest large asteroid, with a surface about three times more luminous than Earth's moon.

NEW YORK — Members of the United Nations met with distinguished astronauts and cosmonauts this week in New York to begin implementing the first-ever international contingency plan for defending Earth against catastrophic asteroid strikes. Six of the space travelers involved in these U.N. discussions discussed the asteroid defense effort Friday (Oct. 25) in a news conference hosted by astrophysicist Neil deGrasse Tyson at the American Museum of Natural History. Their goal: to drive home the very-real threats posed by near-Earth objects (NEOs), or asteroids traveling within the radius of Earth's orbit with the sun. You can see a video of...

60 Minutes news program ran a segment entitled "Dangerous game of 'cosmic roulette'?" This segment highlighted the NASA program aimed at finding and tracking asteroids whose orbits cross Earth's thus placing them on a collision course with us. The NASA administrators at first bragged about how they knew with confidence about 95% of all the "major" threats to our planet and were currently tracking these threats. These administrators were clearly trying to convey to the public an attitude of "don't worry, we have it all under control." Yet as with most statements by government bureaucrats the devil is in the...

Albert Einstein. George Takei. Jerry Garcia. All of those men and many others have had an asteroid named after them. And if William Lowell Putnam III, trustee of Lowell Observatory, has his way, another name will be added to that list: Trayvon Martin. The retired broadcast executive, alpinist, author and Flagstaff resident believes that Martin has not received justice.
