Sun’s Most Powerful Solar Flare of the Year
NASA’s Solar Dynamics Observatory captured this image of an M6.5 class flare at 3:16 am EDT on April 11, 2013. This image shows a combination of light in wavelengths of 131 and 171 Angstroms. Image © NASA/SDO
Fiery Looping Rain on the Sun
Eruptive events on the Sun can be wildly different. Some come just with a solar flare, some with an additional ejection of solar material (called a coronal mass ejection – CME), and some with complex moving structures in association with changes in magnetic field lines that loop up into the Sun’s atmosphere, the corona. On July 19, 2012, an eruption occurred on the sun that produced all three. Watch the video…
Magnificent CME Erupts on the Sun
A long filament of solar material that had been hovering in the Sun‘s atmosphere, the corona, erupted out into space. The coronal mass ejection, or CME, traveled at over 900 miles per second, held on August 31, 2012 at 4:36 p.m. EDT. Watch the video
Incandescent Sun- like you have never seen it before

Solar corona in total eclipse
During this total solar eclipse in 2008, the solar corona can be seen with naked eye.
The beauty of Cloud Iridescence
Cloud iridescence is a fairly uncommon phenomenon and is usually observed in altocumulus, cirrocumulus clouds, most frequently seen near to the sun when small ice crystals in clouds individually scatter light.
Sun’s Magnetic Map
The Sun’s corona is threaded with a complex network of magnetic fields, and this amazing new image from the Solar Dynamics Observatory shows the magnetic field lines associated with a coronal hole that is now turning to face Earth.
