NASA Releases Time-Lapse of a Full Year of Solar Activity [video]

Turn and move NASA gives us fascinating videos of the Sun, showing huge explosions and simply spectacular plasma ejections - and a bit scary too! For recently, the space agency has decided to release a video featuring time-lapse images containing a full year of solar activity.

According to Anthony Wood of the Gizmag portal, the video was created from images captured by the unmanned Solar Dynamics Observatory spacecraft, which was sent to space in early 2010 and is intended to enable astronomers to study complex electromagnetic processes. that occur in the solar atmosphere. Watch the following video:

Hot and active

According to NASA, the images that make up the time-lapse were captured between January 1, 2015 and January 28, 2016, at 12-second intervals. In addition, each frame of the video represents 2 hours of solar activity, and the recordings were made at 10 different wavelengths.

As the space agency staff explained, in the case of the clip, the images are based on a wavelength of 171 angstroms - that is, at the ultraviolet end, a length normally invisible to human eyes - and show the Sun-recorded activities that reach temperatures of almost 600, 000 degrees Celsius.

And if you pay attention, throughout the clip, our star seems to subtly grow and shrink, move briefly on the screen and even fade in some frames. This is because the spacing of the spacecraft from the sun varies over time - but considering that the earth orbits the star at nearly 108, 000 kilometers per hour and the spacecraft orbits our planet at over 11, 000 km / h, The images are super stable!

With this kind of material, astronomers can better understand the electromagnetic system that causes so much movement in the sun - and understand how this constant activity affects the earth. In addition, images also allow scientists to learn more about other stars that exist in our galaxy.

Do you fear that someday there will be an explosion in the sun that seriously affects life on our planet? Comment on the Mega Curious Forum
