It is actually NASA's Solar Dynamics Observatory that did a 360 and rolled completely around its axis.

NASA’s newly-released animation will make you feel dizzy.

On July 6, Solar Dynamics Observatory or SDO did a stunning somersault and rotated 360 degrees around on one axis. The maneuver was the part of a plan that was intended to collect some crazy data about the Sun. SDO captured an image of the Sun every 12 second for seven hours and turned it into a spinning fireball.

SDO rolls completely around its axis twice a year and helps scientists understand how the outer edge of the Sun looks from spacecraft's perspective. The animation has been created with the help of SDO’s Helioseismic and Magnetic Imager, or HMI – one of the three instruments onboard the spacecraft assigned to take precise measurements of the solar limb or Sun's outer edge and to study the shape of the Sun.

Sun is only visible in extreme ultraviolent wavelengths that are typically impossible to see with naked eye. Therefore, the latest video is colorized in gold for easy viewing.

SDO was launched in 2010 and is designed to study solar activity on small scales of space and time and in many wavelengths simultaneously. The ultimate goal is to understand Sun’s impact on Earth and the space around it.

The Sun has a defined 11-year cycle for its solar activity, during which the sun goes through the periods of great and less activity. With SDO instruments, researchers try to understand how the shape of the sun changes with respect to the solar cycle
