An astrophotographer has captured a hauntingly lovely picture of an enormous plume of plasma capturing out of the sun. The fiery filament, referred to as a coronal mass ejection (CME), prolonged into space to a distance of greater than 1 million miles (1.6 million kilometers) from the solar floor, in accordance with the photographer.
The picture was captured Sept. 24 by skilled astrophotographer and Arizona resident Andrew McCarthy (opens in new tab), and he shared the beautiful view on Reddit on Sept. 25 within the subreddit r/space (opens in new tab). The CME was a part of a minor solar storm — G-1 class, the bottom class on the Nationwide Oceanic and Atmospheric Administration’s (NOAA) Geomagnetic Storm Scale — and was pointed away from Earth, in accordance with SpaceWeather.com (opens in new tab).Â
The ethereal ejection was “the most important CME I’ve ever witnessed,” McCarthy wrote on Reddit. The plasma was initially contained in a big loop related to the sun‘s floor, referred to as a prominence, after which broke off and streamed into space at round 100,000 mph (161,000 km/h), McCarthy added.

The picture is a false-color composite time-lapse picture that stacks a whole lot of 1000’s of photos captured over a six-hour interval, McCarthy wrote. Between 30 and 80 particular person photos had been captured each second after which had been saved in a file that finally peaked at round 800 gigabytes. The pictures had been then mixed to indicate the CME in superb element.
Within the picture, the sun’s floor and CME seem orange — however in actuality, they don’t seem to be. The chromosphere (the bottom area of the sun’s environment) and CMEs naturally give off a sort of sunshine that appears pinkish-red to us and is called hydrogen-alpha, or H-alpha, gentle. However as a result of the publicity time of every picture was so brief, the unique photos had been virtually fully white. McCarthy digitally added the orange whereas compositing the ultimate picture, to supply distinction between particular person buildings on the solar floor and to focus on the CME.
Nonetheless, as the remainder of the picture was not filtered with orange, the sun retains an eerie white halo that stands out in opposition to the darkish backdrop of space.

CMEs have turn out to be extra frequent in latest months because the sun has entered a interval of elevated solar exercise referred to as the solar most, which lasts round seven years. It will present many extra alternatives for individuals to seize comparable photos.
“We’ll see extra of those as we head additional into solar most,” McCarthy wrote. The plasma plumes are additionally more likely to get “progressively bigger,” he added.
The photographer warned individuals in opposition to attempting to look at the sun with out the correct tools.
“Don’t level a telescope on the sun,” McCarthy wrote on Reddit. “You may fry your digital camera or worse, your eyes.” The telescope he used to {photograph} the CME was “specifically modified with a number of filters” with the intention to safely observe the CME and seize the photographs, he added.Â
