These 7 NASA Photos Show How Complex Our Star Really Is

  These 7 NASA Photos Show How Complex Our Star Really Is NASA has taken some impressive photos of the sun's surface while studying our star.NASA is constantly assessing data from the sun and even has a telescope trained on the sun all the time. The Solar Dynamics Observatory launched in 2010 with the goal of studying solar variability and weather and what impacts those have on Earth and the space around Earth. Every day NASA posts photos taken by the SDO online so that anyone can go look at what the sun is currently up to. On Friday, the image of the sun was detailed and showed a few flares coming off the surface of the giant star and the surface swirling. It was taken in the 171-angstrom wavelength by the SDO.

It is the strongest solar flare yet for 2012. According to Phillips, the big X5.4 solar flare erupted from the giant active sunspot AR1429, which was also responsible for the major sun storm on Sunday.

The sun blasted out seven massive solar flares in as many days in an extraordinary period of space weather that has sparked stunning geomagnetic storms above the earth.

Between September 4 and September 11, NASA observed seven flares, all classed in its strongest “X” category, with the most impressive registering at X9.3, a very significant event.

The latest, at X8.2 also a significant flare, peaked at 12:06 p.m. EDT on Sept. 10. It prompted warnings of possible radio blackouts from the Space Weather Prediction Center, which also issued a geomagnetic storm warning for Wednesday and Thursday.

Why the Northern Lights might have been to blame for the mysterious deaths of 29 sperm whales

  Why the Northern Lights might have been to blame for the mysterious deaths of 29 sperm whales The great beasts weren’t starving or diseased, but had all died in an area where they typically were not expected to be .Marine science was stumped.Now a team of German researchers is arguing that the culprit behind the mass whale killings is also responsible for one of nature’s most breathtaking sights: the Northern Lights. Klaus Heinrich Vanselow, a German marine biologist at Kiel University in Kiel, Germany, says in a new paper in the International Journal of Astrobiology that the whales rely, in part, on the Earth’s geomagnetic field to navigate.

Solar flares occur when a buildup of magnetic energy on the sun is suddenly released. They usually erupt from sunspots, temporary dark and relatively cool patches on our star's surface where the local magnetic field is very strong . Flares generate a burst of radiation across a wide range of the

The X9.3 solar flare was named by NASA as the strongest so far in the current solar cycle, a roughly 11-year period that began in December, 2008. The solar activity has been linked to increased aurora activity in the northern skies.

“The current solar cycle ... is now decreasing in intensity and heading toward solar minimum,” NASA said, “This is a phase when such eruptions on the sun are increasingly rare, but history has shown that they can nonetheless be intense.”

All the flares have emerged from the same “active region” of the sun, dubbed AR2673.

These events have been extremely intense, but none has caused serious disruption on Earth, and there’s no indication that the solar situation is going to get worse.

But that won’t always necessarily be the case in the future. In 1989, Canada’s Quebec state faced a nine-hour blackout from a solar event called a Coronal Mass Ejection. 

Solar flares could also disrupt communications, including crucial satellite guidance system that could affect airplanes.

The Asteroid Belt May Be a 'Treasure Trove' of Planetary Building Blocks .
The asteroid belt may have started out empty, later becoming a "cosmic refugee camp" taking on leftovers of planetary formation from across the solar system, a new study finds. The main asteroid belt, located between the orbits of Mars and Jupiter, makes up 0.05 percent the mass of Earth. The asteroids there can range greatly in mass, with the four largest ones — Ceres, Vesta, Pallas and Hygiea — holding more than half the belt's mass.
