Once, we will break the usual advice and tell you that you should stare at the sun very much. Specifically, please include it in NASA’s latest 10-year time-lapse photography video.
In 61 minutes, this awesome video was created from high-resolution images taken by the Solar Dynamics Observatory (SDO) spacecraft over the past decade. Every second in the video represents a day in the center of the solar system.
Observe the sun’s corona-the outermost layer of its atmosphere-blinking and burning every day, while charged plasma particles circulate up and down the surface. This is a view of the sun that is usually hidden from our field of view by its brightness.
Using one photo for each observation hour from June 2, 201
If you want our favorite highlight, check out Venus passing by the sun on June 5, 2012-this will not happen again until 2117. For more highlights, please watch this video.
SDO uses light of various wavelengths to collect pictures for observation to obtain details and functions that may be missed. For this video, the extreme ultraviolet wavelength (17.1 nm) was used.
Since its release on February 11, 2010, SDO has accumulated an amazing 425 million photos by capturing images every 0.75 seconds-a total of 20 million gigabytes of data, enough to fill countless photo albums.
We would like to thank the spacecraft for the discovery of electromagnetic bursts and solar flares on the surface of the sun. Tracking this activity is essential for further understanding of the function of the sun and its impact on other parts of the solar system.
Although the sun is vital to life on our planet, we still don’t know much about it-including the behavior of the corona. Like the observations made by SDO, it should help us find answers faster.
If you suddenly see the sun disappear from the video, don’t panic-it’s the earth, the moon or both hindered it, or the result of a temporary problem with the SDO instrument in 2016.
If the time-lapse video attracts more appetite, we encourage you to check the NASA official page of the Solar Dynamics Observatory. You can see the current view from the spacecraft, find out where you are in the sky, see some of the best photos it has ever taken, and more.
For us, we will return to the beginning of the time in the game and watch it again.
