NASA turns images from the Solar Observatory into a time lapse of the Sun's life over the past 10 years – Technology News, Firstpost


NASA's solar dynamics observatory (SDO) completed a decade continuously watching the sun last month. Marking the 10th anniversary, the US space agency released a time-lapse video of the sun in all its glory.

SDO collects images of the sun in high resolution as it orbits the Earth as of June 2010. Over the years, it has accumulated about 425 million photos that were stitched together to form the video. Data worth 20 million gigabytes were collected by the observatory using three main instruments, including the set of atmospheric images (AIA).


This 10-year lapse of the Sun at 17.1 nanometers (an extreme ultraviolet wavelength that shows the Sun's outermost atmospheric layer – the corona) shows the rise and fall of the solar cycle and notable events such as transiting planets and eruptions solar.

Entitled A Decade of the Sun& # 39;, every second of the video shows a full day. So, in just over an hour (precisely 61 minutes), you witness the sun for 10 years.


You can see the rise and fall of the solar cycle, along with "transiting planets and solar flares". However, there were occasional dark frame moments. An article by NASA claims that this is because of the Earth or moon eclipsing the SDO as they pass between the spacecraft and the sun.

A much longer dark phase can be witnessed in 2016; this was caused due to some problem with the AIA instrument that captures images of the sun every 12 seconds in 10 different wavelengths of light.

The article explains that, in cases where the sun is not in the center of the frame, the SDO was "calibrating your instruments".


From the long video, on the 12:24 date stamp, the year is 2012 and we can see Venus passes by the face of the sun. This would not happen again until 2117. Many of these interesting eruptions and eruptions are seen throughout the video.
