NASA's latest space telescope, the Solar Dynamics Observatory, is delivering unprecedented images of our local star. The telescope was launched on 11 February. NASA released the first tremendously exciting data from the mission on 21 April.
"These initial images show a dynamic sun that I had never seen in more than 40 years of solar research," said Richard Fisher, director of the Heliophysics Division at NASA, in a release. "SDO will change our understanding of the sun and its processes, which affect our lives and society. This mission will have a huge impact on science, similar to the impact of the Hubble Space Telescope on modern astrophysics."
