Biggest solar flare of the year knocks out radio transmissions

Early this morning the sun erupted, sending billions of solar particles into space at over 600 miles per second, raising the prospect of solar radiation storms above the Earth, according to NASA. A spokesman said the resulting emissions sparked a short-lived radio communications blackout on Earth. The radio disruption has since subsided. The appearance of the strongest solar storm of 2013 is part of an increasingly common sight as astronomers say this is connected to the sun's 11-year activity cycle. More intense solar eruptions are expected later in the year.

Stephen Hawking predicts end-of-Earth scenario

Stephen Hawking, one of the world's greatest physicists and cosmologists, is once again warning his fellow humans that our extinction is on the horizon unless we figure out a way to live in space.

Not known for conspiracy theories, Hawking's rationale is that the Earth is far too delicate a planet to continue to withstand the barrage of human battering.

"We must continue to go into space for humanity," Hawking said today, according to the Los Angeles Times. "We won't survive another 1,000 years without escaping our fragile planet."… Read more

NASA's plan to bag an asteroid wins place in Obama's budget

Turns out that crazy rumor was true: NASA is planning to capture an asteroid.

The plans were included in the space agency's $17.7 billion fiscal 2014 budget, part of the new $3.7 trillion government budget proposed earlier today by President Obama.

In the budgets, about $78 million is set aside for a plan that involves sending a craft to rendezvous with what's described as a "small asteroid," and then moving the space rock into a stable orbit near the moon. Astronauts will later visit the asteroid and scoop up samples for study back on … Read more

Astronauts don't cry: Chris Hadfield shows tears in space

There's no crying in baseball, and there's no crying in space.

While zero gravity doesn't have an impact on tears forming, it has an effect on if they fall -- and they don't. The water that builds up in your eyes from crying will stay there until the bubble gets so big it moves to another spot on your face, or it's removed. It's not very pretty or graceful.

Watch how Canadian astronaut Chris Hadfield -- commander of the International Space Station and maker of all sorts of entertaining space videos -- demonstrates what … Read more

Blast your angry face into space to ward off alien invasions

While NASA has been busy sending friendly messages out into space, it's overlooked one important issue. What if the aliens aren't friendly? Haven't the folks at NASA watched the "Alien" movies? A Kickstarter project is aiming to counteract NASA's open-arms policy by blasting a satellite into space with a less likeable version of humanity onboard.

In the 1970s, NASA sent two Pioneer spacecraft out into the universe bearing plaques with directions to Earth and illustrations of naked humans to show what extraterrestrial visitors could expect upon arrival at our humble planet. Ridiculo.us, creators of the Your Face in Space Kickstarter, is more concerned about warding off hostile invasion forces from beyond our solar system.… Read more

Astronaut Chris Hadfield shows off his spacesuit waltz

Flying aboard the International Space Station isn't just fun and games; members of the crew have to examine their equipment to keep everything in ready-to-use condition. One of the most important pieces of equipment is the spacesuit worn by astronauts when they leave the ISS to go out into the universe.

Spacesuits are made to keep a human body alive in the harsh, anti-gravity environment of space, but they are also used inside a ship should there be a change of pressure.

They are often constructed to help keep the wearer comfortable, keeping in mind mobility and the need to collect solid and liquid waste, "Spacesuits are just really one person spaceships," ISS Commander Chris Hadfield explains in his video. … Read more

Feast your eyes on the Small Magellanic Cloud

Astronomers describe it as a "dwarf galaxy," but the Small Magellanic Cloud, which happens to be one of the Milky Way's closest neighbors, is entirely majestic.

This galactic region takes its name from Ferdinand Magellan, a 16th century explorer who reportedly referred to the cloud's placement in the sky to guide his ship on his worldwide journeys.

In this spectacular composite image released today by NASA's Marshall Space Flight Center, in Huntsville, Ala., scientists are reporting what they say is the presence of X-rays being emitted from young stars -- or "suns" -- … Read more

Watch: How to brush your teeth in space

For those of you who hate brushing your teeth under normal circumstances, think about how much harder it is to clean those pearly whites in space, with zero gravity and no sink to get water from or spit into afterwards.

In another in his series of entertaining how-to videos from space, International Space Station Commander Chris Hadfield shows how to take care of those chompers in space. Does the toothpaste go up your nose? How do you get the toothbrush wet in the first place?

Check out the below video in which Hadfield answers those questions and more. And here's a spoiler: he has a unique way of cleaning his toothbrush post usage. … Read more

Watch astronaut Chris Hadfield's zero-gravity workout

If you think your workout is reaching a plateau, don't complain to the men and women in space. They have to constantly work out to stave off the loss of muscle tissue.

People living in zero gravity can lose up to 5 percent muscle mass a week. Yikes! That's why working out isn't just something astronauts do because they had a double cheeseburger with onion rings for lunch. Curious about what a space workout looks like? … Read more
