Astronomy lovers preparing to lose sleep for tonights lunar eclipse

VANCOUVER (NEWS1130) Heres a good reason to let your kids stay up past their bedtime; there will be a lunar eclipse tonight.

This particular event will see the moon turning into the colours of a sunset.

John Tanner with the HR MacMillan Space Centre says you dont need to do much just go outside!

Try and pick a nice dark spot and really notice the difference in brightness because if youre away from the city or a nice dark backyard, youll notice how much darker it gets during the eclipse. You might see the Milky Way stretching in the sky; youll see more stars showing up.

The Space Centre has an evening of events planned.

The eclipse itself is expected to start just before 10 p.m., with the main event coming just after midnight.

Just before 11 oclock youll start to see a little black nick [on] the side of the moon and slowly moving across and, of course, thats the shadow of the Earth. And, by 12:06 a.m., it will be fully in the shadow and its an eclipse! describes Tanner.

If you miss out, dont worry: This is just the first of four lunar eclipses that will be visible over the next two years.

AI gets its groove back

Try this: Go online to translate.google.com.

In the left-hand input box, type, "The spirit is willing, but the flesh is weak." In the right-hand box, decide which language you want it translated to. After it's translated the first time, copy the translated text and paste it into the left-hand box for conversion back into English.

If you don't get exactly the original text, the back-translation will in all likelihood still reflect at least part of the original thought: That the actions of the subject fell short of his or her intentions and not that the wine was good but the meat was tasteless, which the phrase could mean in a literal translation.

AI is becoming real. Jackie Fenn, Gartner Analyst

In other words, a machine figured out what you meant, not merely what you said.

"In the 1960s, this was considered impossible," explains Michael Covington, a consultant and retired associate director of the Institute for Artificial Intelligence at the University of Georgia.

For decades the field of artificial intelligence (AI) experienced two seasons: recurring springs, in which hyped-fueled expectations were high; and subsequent winters, after the promises of spring could not be met and disappointed investors turned away. But now real progress is being made, and it's being made in the absence of hype. In fact, some of the chief practitioners won't even talk about what they are doing.

Seasons old and new

"AI is becoming real," says Jackie Fenn, a Gartner analyst. "AI has been in winter for a decade or more but there have been many breakthroughs [during] the last several years," she adds, pointing to face recognition algorithms and self-driving cars.

Researcher Daniel Goehring, a member of the Artificial Intelligence Group at the Freie Universitaet (Free University), demonstrates hands-free driving during a 2011 test in Berlin. The car, a modified Volkswagen Passat, is controlled by 'BrainDriver' software with a neuroheadset device that interprets electroencephalography signals with additional support from radar-sensing technology and cameras.
