Surface of the Sun as you’ve Never Seen It
This extraordinary 3 min video looks back on the 3rd year of operation of NASA’s Solar Dynamics Observatory. Since its launch in 2010, SDO’s data and imagery have exceeded everyone’s hopes and expectations, providing stunningly detailed views of the sun. Watch the stunning video…
Happy 540th birthday Copernicus
On February 19th was Nicolaus Copernicus‘s 540th birthday. He is widely known as the father of modern astronomy and for arguing that the Earth revolves around the Sun. He never earned a bachelor’s degree and he practiced medicine, without a medical degree. Image © wikipedia
Magnetic Loops on the Sun
This image of magnetic loops (like flux ropes) on the sun, captured by NASA’s Solar Dynamics Observatory (SDO). It has been processed to highlight the edges of each loop to make the structure more clear. Image © NASA/Goddard Space Flight Center/SDO
Why Scientists Observe the Sun in Different Wavelengths

Earth’s Magnetosphere behaves like a Sieve
ESA’s quartet of satellites has discovered that Earth’s Magnetosphere behaves like a sieve in orbit, and that our protective magnetic bubble lets the solar wind in under a wider range of conditions than previously believed.
Graceful, Gradient Sun
Our Graceful Sun can be seen thru a gradient filter, in this impressive video from NASA’s Goddard Space Flight Center. Sometimes science and art can go along! Watch the beautiful video…
Inverted Sun and Starfield
If this dark ball look somehow familiar, it’s because it’s our Sun. In the above image, the Sun and a starfield are color inverted. Image credit: Jim Lafferty Used with permission.
