As of June 2020, NASA’s Solar Dynamics Observatory – SDO – has now been watching the Sun non-stop for over a full decade. From its orbit in space around Earth, SDO has gathered 425 million high-resolution images of the Sun, amassing 20 million gigabytes of data over the past 10 years. This information has enabled countless new discoveries about the workings of our closest star and how it influences the solar system.
With a triad of instruments, SDO captures an image of the Sun every 0.75 seconds. The Atmospheric Imaging Assembly (AIA) instrument alone captures images every 12 seconds at 10 different wavelengths of light. This 10-year time lapse showcases photos taken at a wavelength of 17.1 nanometers, which is an extreme ultraviolet wavelength that shows the Sun’s outermost atmospheric layer – the corona. Compiling one photo every hour, the movie condenses a decade of the Sun into 61 minutes. The video shows the rise and fall in activity that occurs as part of the Sun’s 11-year solar cycle and notable events, like transiting planets and eruptions. The custom music, titled “Solar Observer,” was composed by musician Lars Leonhard.
While SDO has kept an unblinking eye pointed toward the Sun, there have been a few moments it missed. The dark frames in the video are caused by Earth or the Moon eclipsing SDO as they pass between the spacecraft and the Sun. A longer blackout in 2016 was caused by a temporary issue with the AIA instrument that was successfully resolved after a week. The images where the Sun is off-center were observed when SDO was calibrating its instruments.
SDO and other NASA missions will continue to watch our Sun in the years to come, providing further insights about our place in space and information to keep our astronauts and assets safe.
Looks like a yellowish corona virus.
Anyhow, has it undergone any global warming in the last decade or so?
And God said “Let there be light”. And it was good.
Really fascinating...and mesmerizing.
The sun was really active in 2014. The immediately passed several years are the opposite — very quiet.
A nice perspective on the Solar Min/Max cycle.
Looks like it’s starting to simmer again at the end.
Nice, thanks for posting.
The Lidless Eye!!! Eeek!.
If ya ask me, the whole thing sounds racist.
The sun is white. Time to tear it down.
Exactly. We’ve seen what it does with black sunspots - kills them all within a few weeks.
Sun’s Racist!
Thanks for posting.
That is really interesting.
I recently read that someone launched a solar observatory that will eventually go into a polar orbit - I can’t recall which space program, though.
Another thought - performing an advanced AI analysis of trillions and trillions of pixel data points will discover many solar patterns that were not obvious before.
