The Curiosity Mars rover has found intriguing veined rocks just below tilted cross-bedded layers that indicate water once flowed and "percolated" through fractured terrain near the landing site in Gale Crater, scientists said today. The discovery provides additional evidence of a watery past on the Red Planet.

Taking their time evaluating a surprising variety of scientific targets, mission scientists and engineers now are gearing up for the first tests of a powerful impact drill that will be used to collect samples from inside targeted rocks.

The drill tests are a final major milestone before the rover begins creeping … Read more

You're onboard the Millennium Falcon. You give the command to jump to lightspeed. The stars outside turn into long streaks of light and you're off. It's one of the most memorable images of sci-fi space travel ever created. It's also likely to be pretty far from reality, according to a study by a group of students from the U.K.'s University of Leicester.

The study, titled "Relativistic Optics Strikes Back," was published in the University of Leicester's Journal of Physics Special Topics. You can indulge in all the delicious physics equations in the abstract.

The physics students started by imagining that the Millennium Falcon has accidentally wandered into our solar system, on a direct course for our sun. If it then engaged in near-lightspeed travel, the stars around it wouldn't appear to stretch out. Instead, it would look more like a disc of light.… Read more

You and I are really, really small. And we're even smaller than we thought we were last month, at least when compared with the size of the largest known item in the universe.

Last week, a team of astronomers based in the U.K. discovered the largest object in all of our observable existence: a celestial structure made up of 73 quasars that is up to 4 billion light years long.

How big is that exactly? Well, it would take tens of thousands of our own Milky Ways -- the big, galactic one, not the one that comes in … Read more

NASA has awarded a contract to explore ways to potentially expand the International Space Station.

The agency announced last week that Bigelow Aerospace has been awarded a $17.8 million contract to deliver to the agency an inflatable extension for the space station. According to NASA, the Bigelow Expandable Activity Module "will demonstrate the benefits of this space habitat technology for future exploration and commercial space endeavors."

Inflatable space technology is nothing new. In fact, the first passive communications satellites -- Echo 1 and Echo 2 -- were both inflatable. NASA determined in 1958 that the satellites would … Read more

The White House has rejected a proposal to build a Death Star, saying that in addition to its prohibitive construction costs, the current administration does not advocate destroying other planets.

Today's lighthearted official statement came in response to a petition posted in November to the White House's We The People platform that called for the administration to begin construction of a moon-size military battlestation armed with a planet-destroying superlaser by 2016. The petition, which attracted well more than the minimum 25,000 signatures necessary for a response from the White House, suggested that such a project could give … Read more

Earthlings can breathe a sigh of relief; NASA scientists have officially ruled out the possibility of the 22 million ton asteroid Apophis smashing into the planet in 2036.

"The impact odds as they stand now are less than one in a million, which makes us comfortable saying we can effectively rule out an Earth impact in 2036," manager of NASA's Near-Earth Object Program Office Don Yeomans said in a statement. "Our interest in asteroid Apophis will essentially be for its scientific interest for the foreseeable future."

Apophis is still en route to come exceedingly close … Read more

Most of the big news this week came out of Las Vegas where gadget geeks gathered for the Consumer Electronics Show. But now for some mind-blowing stuff, courtesy of NASA: An international team of astronomers has determined that a stellar system called NGC 6872 is more than five times the size of our Milky Way galaxy and thus holds the title of the biggest spiral galaxy known to science. How big is big? Think about it this way: the spiral galaxy spans more than 522,000 light-years across.

The first American manned spacecraft to reach orbit in the wake of the shuttle's retirement will be crewed by company test pilots -- not NASA astronauts -- in part to give space agency managers better insight into flight readiness and safety, officials said Wednesday.

Assuming NASA gets the funding that managers say they need -- a big "if" in today's political environment -- Space Technologies Corp., or SpaceX, hopes to launch a manned version of its Dragon cargo ship in the mid 2015 time frame, followed by a crewed flight to the International Space Station later … Read more

LAS VEGAS--No one has ever met Dr. X.

And even though he claims to have created breakthrough medical technology and powerful cures with the help of alien beings, Dr. X won't show at CES.

But his QuantumMan app is here. It supposedly diagnoses and heals your ailments with the simple touch of a smartphone, a few ounces of faith, and some good old cash.

At a small booth in the Las Vegas Convention Center's mile-long South Hall, somewhere between Wacom Technology and VistaQuest, Extraterrestrial Technology is pushing QuantumMan medical treatments at CES 2013. … Read more
