Marvel at NASA's mesmerizing 3-years-of-sun-shots video

We've always been told not to stare at the sun, but NASA's Solar Dynamics Observatory (SDO) has been doing just that for the last three years. Since it started operations, the SDO has taken a shot of the sun using its Atmospheric Imaging Assembly every 12 seconds on 10 different wavelengths, giving scientists an unprecedented look at the shifting moods and surface of our nearest star.

NASA put together a 3-minute video of the sun's last three years and set it to lovely music. The result is a yellow, fluctuating, spinning globe, spitting out flares over time. It's nearly hypnotizing.… Read more

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.

What's up with the sun? Plenty

We're currently in the midst of what scientists say is the sun's 11-year solar weather cycle, and it's making for quite the show. Over the last few months, NASA and the European Space Agency have been recording solar flares as they erupt, tracking solar storms that send charged particles in Earth's direction at roughly 1.8 million miles per hour. In case you were tempted to do the math, radiation from solar flares make it to Earth within eight minutes.

What's more, the frequency of the storms is expected to increase and reach its peak … Read more

Earth cozies up super close to the sun today

Looking out my window, it's a beautiful sunny day. Perhaps it's even a bit sunnier than usual here in New Mexico. Turns out, there may be a reason for that. The Earth is as close to the sun today as it will be for the whole year of 2013.

How close is close? The Earth is a mere 91,402,560 miles away from the sun today. Usually, we're right around 93 million miles. The phenomenon of getting all cuddly with our closest star is called perihelion. "Peri" means near and "Helios" was the Greek god of the sun. … Read more

Oracle turns in a mixed bag in 2nd-quarter results

Oracle today reported better-than-expected second-quarter earnings, revenue that was lighter than estimates, and hardware system product sales that fell 23 percent from a year ago.

In other words, Oracle's quarter was a mixed bag (preview).

Oracle reported second-quarter earnings of $2.6 billion, or 53 cents a share, on revenue of $9.1 billion, up 3 percent from a year ago. Non-GAAP earnings were 64 cents a share.

Wall Street was expecting Oracle to report second-quarter earnings of 61 cents a share on revenue of $9.02 billion.

New license and cloud revenue was up 17 percent in the … Read more

World's tallest tower to overshadow monumental goof in Ecuador

MITAD DEL MUNDO, Ecuador--The effort to mark exactly where the equator traverses this tiny country roughly the size of Colorado -- if Colorado were filled with not just tall, jagged mountains, but also with jungle and rainforest and swamp and humid lowlands -- has been filled with centuries of folly and misplaced monuments. Now a provincial government in Ecuador wants to finally get it right, and make a big statement at the same time.

Despite being the longest way around the Earth, the equator is relatively hard to get to. Just take a look at your globe (OK, Google Earth will do) and you'll notice it passes through an awful lot of empty ocean, some remote islands, the Amazon, and some typically inaccessible parts of Africa. These raw geographic realities have made Ecuador particularly important for those on a quest for middle earth (not Middle Earth) for centuries. … Read more

An amazing view to a total solar eclipse

Did you miss out on the total solar eclipse yesterday?

Take a look at our breathtaking gallery that features pictures of the total (and partial) solar eclipse from the northern tip of Australia, various island countries in the South Pacific, and near Chile.… Read more

Where to watch Tuesday's total solar eclipse

Did you know a total solar eclipse occurs tomorrow? Unfortunately, unless you live around certain areas in Australia or find yourself floating in the South Pacific Ocean, you won't really see the full effect -- unless you observe the phenomenon online.

If you want to catch the rare moment where the moon passes between Earth and the sun, Space.com recommends tuning in to the Slooh space camera Web site or a live feed by Tourism Tropical North Queensland on UStream. … Read more

Earth-like planet -- sorta -- spotted in Alpha Centauri

Roughly 25 trillion miles (or 4.3 light years) from home, astronomers have found that the Alpha Centauri star system hosts a planet with a mass similar to that of Earth. Galactic geeks may recall references to this star system in "Star Trek," "Avatar," "Transformers," and countless other fictional entertainment.

The planet, officially named Alpha Centauri Bb, orbits Alpha Centauri B and took more than four years of observing to fully classify. … Read more
