guatemala-sinkhole "This can't be real" was my first thought. Then I checked the source: The Guatemalan government. This sinkhole appeared last sunday in a street intersection of Ciudad de Guatemala. Just looking at the photo gives me vertigo.

A sinkhole is a natural depression caused by the removal of underground soil by water. Usually, it happens when the substrate is formed by limestone, carbonate rock, salt beds or any other rock that is easily eroded by water streams. The process could be slow, but sometimes the land just cracks open without notice. In this case, it happened suddenly, swallowing an entire house. The cause: Massive underground water torrents created by tropical storm Agatha.

facebook_glasses Facebook will be rolling out its promised “simplified” privacy controls to its users starting Wednesday, Facebook vice president Chris Cox announced Tuesday.

Cox made the announcement from the stage at the TechCrunch Disrupt conference in New York City.

The venue is hardly surprising and in keeping with Facebook’s recent reliance on sympathetic media outlets to combat the backlash against its overweening ambitions and abysmal privacy practices. TechCrunch’s founder and head Michael Arrington recently came to the company’s defense, chastising the media for being too hard on Mark Zuckerberg.

On Monday, the Washington Post gave the company free space on its Op-Ed page to write a nearly content-free post on how it was listening to users. In fact, the company is promising little to its users and seems set to continue its new practice of turning over user data to third parties without getting prior permission.

Coincidentally, Washington Post publisher Donald Graham is on Facebook’s board and is a mentor to Zuckerberg. As Ryan Tate at Valleywag puts it: “An opinion piece in one of the nation’s most prestigious newspapers carries more moral authority than a blog post on,” and that Graham has been a sort of “press consigliere for the startup founder.”

With a golden record on board, it left the Earth 33 years ago.

NASA installed the 12-inch disk containing music and greetings in 55 languages in case intelligent extraterrestrial life ever found it.

But now the Voyager 2 spacecraft is sending back what sounds like an answer: Signals in an unknown data format!

The best scientific minds have so far not been able to decipher the strange information – is it a secret message?

By John D. Sutter                                      , says NASA, but maybe not in a government-built spaceship -- and maybe not any time soon.The future of American space exploration came into question on Monday as President Obama released his 2011 budget. If passed by Congress, the budget would eliminate Constellation -- NASA's project to send humans back to the moon by 2020.

Constellation was to follow NASA's space shuttle program, which, after about 30 years of taking astronauts to space, is scheduled to end later this year, following five more flights.

Instead of building new spacecraft of its own, NASA, under the proposal, would invest in space technology research and spend $6 billion to pay private space groups to develop and build new rockets to take astronauts into orbit.

The plan leaves many open questions about the future of U.S. space travel, including if and when NASA will ever build rockets of its own again, when astronauts will return to space and in what kind of spacecraft.

"It's almost like a reboot of NASA's human space flight program," said Tariq Malik, managing editor of
