An enormous photo voltaic twister and an enormous plasma eruption had been simply raging on the floor of the sun on the similar time — and a researcher has captured each in a single spectacular picture.
Though the photo voltaic occasions are unrelated, each are the results of disturbances within the solar’s invisible magnetic field, with some plasma compelled right into a twister form and a few plasma launched in a towering eruption often known as an eruptive prominence.
Maximilian Teodorescu, a researcher on the Institute of House Science in Romania, captured each occasions occurring concurrently Wednesday (Aug. 20). He instructed Dwell Science that a big photo voltaic twister is fairly uncommon and he is by no means seen one concurrently an eruptive prominence.
Spaceweather.com reported that astronomers all over the world have been monitoring the twister on the solar’s floor this week, with the earliest photos rising Sunday (Aug. 17). Photo voltaic tornadoes seem like tornadoes on Earth, however the two phenomena have little in common otherwise, notably in the case of dimension.
“[The solar tornado is] about 130,000 kilometers [80,000 miles] excessive,” Teodorescu stated. “Principally a tenth of the diameter of the solar.”
To place that into perspective, Earth is round 7,926 miles (12,756 km) extensive, so this twister is somewhat taller than 10 Earths stacked on high of one another. Photo voltaic tornadoes are usually round 15,500 to 62,000 miles (25,000 to 100,000 km) tall, so this one is a whopper.
Teodorescu estimated that the eruptive prominence was round 124,000 miles (200,000 km) extensive. That is roughly comparable in dimension to a giant solar prominence noticed in July, which was estimated at greater than 100,000 miles (165,000 km) throughout and nicknamed “The Beast.”

Teodorescu first noticed the photo voltaic twister on the Global Oscillation Network Group (GONG) web site Monday (Aug. 18). GONG, which is operated by the Nationwide Photo voltaic Observatory, has six equivalent photo voltaic telescopes that monitor the solar in nearly actual time from completely different international locations all over the world, permitting amateurs and professionals to remain up to date on photo voltaic exercise.
Teodorescu’s spouse and fellow Institute of House Science researcher Eliza Teodorescu helped him align a telescope’s area of view with the twister so he may seize photos of the occasion. The eruptive prominence then emerged, permitting him to snap each on the similar time.
Earth’s tornadoes are whipped up by intense winds and transfer round, whereas photo voltaic tornadoes are fabricated from ionized fuel (plasma) that is rooted in place. They’re formally referred to as tornado prominences, with common prominences additionally held in place by magnetic fields.
Prominences are hooked up to the seen floor of the solar, or photosphere, and prolong into the star’s outer ambiance, or corona, in line with NASA. An eruptive prominence happens when the magnetic area holding the plasma turns into unstable and bursts outward. (Fortunate skywatchers acquired an opportunity to see prominences erupting in real time through the April 8 whole solar eclipse final yr.)
In lots of instances, the plasma launched in a prominence then flies into area as a coronal mass ejection (CME). The sort of photo voltaic storm can collide with Earth’s magnetic area and create auroras, in addition to disrupt our satellites and communication techniques.
Maximilian Teodorescu famous that the eruptive prominence he photographed launched a CME. However it is not heading for us, so it will not lead to any disruptions or northern lights shows, he stated. Earth is, nevertheless, presently being buffeted by photo voltaic winds due to different photo voltaic exercise, so auroras may very well be seen at excessive latitudes tonight, Dwell Science’s sister web site Space.com reported.
The solar is presently in essentially the most lively section of its roughly 11-year photo voltaic cycle — often known as solar maximum — when the star’s magnetic area weakens and flips. Maximilian Teodorescu famous that there is loads of photo voltaic exercise to see even with a small telescope — supplied it’s safely outfitted with a solar filter.
“It is essentially the most dynamic factor you’ll be able to truly see as each [an] beginner and knowledgeable within the sky,” he stated.
