On the 23rd, NASA has published new images in high definition of the nearest star, the mother of our solar system.
NASA observed from the observatory (Solar Dynamics Observatory), images were collected during 12 months from January 11, 2015 to January 21, 2016. The light band in the center of the solar disk is the product of 12 months of observation of bright active areas in the lower crown, whose temperature reaches several million degrees of solar atmosphere.
In approximately 11 years of the solar cycle, magnetic activity from the interior of the Sun becomes more severe, reaching a "solar maximum" when solar flares and coronal mass ejections are common. Cosmic weather can have serious consequences for our planet. These explosive events occur in the active regions - regions of intense magnetic activity, which cause a strong heating of the solar plasma. After the maximum of explosions, the solar's global magnetic field begins to decrease, eventually reaching a "solar minimum" when the Sun subsides at rest. We are currently experiencing a time of rest, since the Sun showed its solar maximum in 2012-2013. But, as you can see from this beautiful portrait, the Sun, of course, does not behave calmly.
The Solar Dynamics Observatory operates only for the sixth year, it was launched on February 11, 2010, its task is to constantly look at the Sun, discovering new, never-seen dynamics of the outer layers of the Sun and its extended corona. This particular series of observations was recorded using a very powerful tool with 171 filters.
As a comparison with the processed image, here is the original single observation from the SDO, recorded today:
