The photo was taken on September 24 by a professional astrophotographer from Arizona.
An astrophotographer has captured a unique image of a massive plume of plasma coming from the Sun. A fiery filament, known as a coronal mass ejection (CME), has spread into space more than 1.6 million kilometers from the Sun’s surface, Science Alert writes.
The photo was taken on September 24 by professional astrophotographer and Arizona resident Andrew McCarthy.
The CME is part of a minor solar storm – class G-1, the lowest category on the National Oceanic and Atmospheric Administration’s (NOAA) geomagnetic storm scale – and is about to leave Earth, the expert said.
“The aerial release was the largest CME I have ever seen,” McCarthy wrote.
It is known that the plasma was originally contained in a large loop connected to the surface of the Sun, which is called a prominence, and then broke and rushed into space at a speed of about 161,000 km / h.
The photo itself is a false-color composite time-lapse image that compiles hundreds of thousands of photos taken over six hours.
“30 to 80 separate images were taken every second and then stored in a file that eventually reached about 800 gigabytes in size. The images were then combined to show the CME in detail. In the image, the surface of the Sun and the CME looks orange, but it really isn’t. The chromosphere (the lowest region of the Sun’s atmosphere) and the CME naturally emit a type of light that appears pinkish red to us and is known as hydrogen-alpha, or H-alpha , light,” added the scientist.
Recall that early scientists from the NASA Solar Dynamics Observatory recorded a surprisingly magnetized area on the Sun.
