Turbulence in the Sun’s corona
Solar wind is a never-ending stream of charged particles coming from the Sun. Rather than a constant breeze, this wind is rather gusty. As solar wind particles travel through space, they interact with the Sun's variable magnetic field, creating chaotic and fluctuating motion known as turbulence.
This video confirms something long suspected: the turbulent motion of solar wind begins very close to the Sun, inside the solar atmosphere known as the corona. Small disturbances affecting solar wind in the corona are carried outward and expand, generating turbulent flow further out in space.
By blocking out direct light coming from the Sun, the Metis coronagraph instrument on Solar Orbiter (www.esa.int/Science_Exploration/Space_Science/Solar_Orbiter) is able to capture the fainter visible and ultraviolet light coming from the solar corona. Its high-resolution images show the detailed structure and movement within the corona, revealing how solar wind motion already becomes turbulent at its roots.
The red-tinted ring in the video shows Metis observations made on 12 October 2022. At the time, the spacecraft was just 43.4 million km from the Sun, less than a third of the Sun-Earth distance. The video of the Sun in the centre of the video was recorded by Solar Orbiter’s Extreme Ultraviolet Imager (EUI) on the same day. (Read more about Solar Orbiter’s instruments here: www.esa.int/ESA_Multimedia/Images/2020/01/Solar_Orbiter_Instruments.)
“This new analysis provides the first-ever evidence for the onset of fully developed turbulence in the Sun’s corona. Solar Orbiter’s Metis coronagraph was able to detect it very close to the Sun, closer than any spacecraft could approach the Sun and make local measurements,” explains Daniel Müller, ESA’s Solar Orbiter Project Scientist.
Turbulence affects how solar wind is heated, how it moves through the Solar System and how it interacts with the magnetic fields of planets and moons it passes through. Understanding solar wind turbulence is crucial for predicting space weather (www.esa.int/Space_Safety/Space_weather) and its effects on Earth.
‘Metis observation of the onset of fully developed turbulence in the solar corona’ by Daniele Telloni et al. was published today in Astrophysical Journal Letters.

Fly over Mercury with BepiColombo

See Mercury in a whole new light, through the ‘eyes’ of the ESA/JAXA BepiColombo (www.esa.int/Science_Exploration/Space_Science/BepiColombo) spacecraft, as it sped past Mercury during its latest encounter on 4 September 2024. During the flyby, BepiColombo’s three monitoring cameras (M-CAMs) captured detailed images of the planet’s cratered surface. Within these images, Mercury scientists identi...

BepiColombo to measure Mercury’s magnetic environment during fourth flyby
Переглядів 54021 день тому
When we look at BepiColombo’s images of Mercury, it can seem like the space around the planet is empty. But in fact, it is teeming with particles - neutral and charged, energetic and sluggish. Mercury has a magnetic field that interacts with particles from the Sun (the ‘solar wind’). This creates Mercury’s magnetosphere - a bubble in space that is shaped like a windsock extending away from the ...

    @ESA Space Science Hub : For non-specialists like me, could you explain how the two pair of scales are converted (the two scales on the x-axis and the two scales on the y-axis, respectively) ? Also, do the colors indicate a different intensity, or something else? Could you possibly add a legend for the colors ?

      This is a spectrogram of a portion of the electromagnetic spectrum at radio frequencies. The x-axis represents time, increasing from left-to-right, the y-axis is radio frequency, increasing from bottom-to-top, and the color indicates received signal strength with blue representing the weakest signal and dark red the strongest, with the other colors representing intermediate values.

    The introduction and normalization (as if it were not too extremely risk-full, even if it were to just psychologically affect others to engage in it, too) of e.g. physical ice moon explorations will certainly lead to astronomically long lasting forwards-contamination, if it happens in a few months, years, decades, a century, or in millennia. Astronomically speaking, to just keep on risking such forwards-contamination - which just requires a 1-time event of its kind to lead to catastrophic consequences humanity has not a shred of a guarantee being able to avert - is not at all sufficient, as one has to think in astronomical time-scales for this matter, where disregarding the fact that the highly irresponsible playing even with just small chances of planetary protection abidance failure can in repetition lead to essentially the same outcome (as it would either way still happen within the same blink of an eye of a time within astronomical times), namely eventual contamination & rapid exponential population growth of microbes on ice moons But instead, the important part - namely to prevent the chance of unfathomable extents of calamity of to the torturous consequences eventually forcefully subjected sentient species' populations that may emerge as consequence of recklessly playing god, kick-starting evolution by contamination - is to prevent it from happening at all ever, and 'ever' is a very long time. I just wish that among the roughly 2090 people or institutions I've contacted so far over the last 5 months to inform & warn them about this long-term fate of humanity deciding matter, there'd been more than just about 1% of them to respond (though in those cases at least with consent), because that's hardly any sufficient level of re-assurance that within the near-future trajectory of the future, i.e. the most critical phase of all in this regard, forwards-contamination risks will be safely outright prevented one way or another. The JUICE mission, just like the Gan De mission, the Laplace-P mission, the Enceladus Explorer mission, the Europa Lander mission, but also interstellar (rather than interplanetary) projects such as Breakthrough Starlight, Breakthrough Starshot, and especially Prof. Dr. Claudius Gros' Genesis project ALL MUST BE CANCELLED. If only more people had the integrity, a shred of empathy, and the mental capacities for understanding, once provided with the information and explanation... it's truly a bleak outlook for - for their very own sake better to never exist, and especially not for billions of years - r-strategist selection species' populations on any ice moon any time in the future at this point, given the overwhelming amount of peer-reviewed scientific studies pointing at suffering to generally dominate among the experiences animal wildlife generally has. At least the Effective Altruism group is for these reasons also strongly opposed to space colonization attempts, but why they haven't been far more outspoken on this grim issue throughout the last 8 years than they have been is a mystery to me. It really seems like one has to do everything oneself. I guess I'll see with how much understanding my informing is met here (and trust me, I've gathered enough disappointing experience to better know to not have my hopes up for it, and it being a very complex, interdisciplinary matter doesn't help either), but apparently I have thousands of more people and institutions yet to warn, all within not that many months, one after another by contacting them, because seemingly internationally, no media agency can be found to help in that regard, besides TED Talk a little bit. In german we'd call this a Trauerspiel - a fiasco.
