The ultimate steam cooker of our solar system is bubbling inside the sun. But where hydrogen atoms merge into helium under immense forces, a journey begins that experiences an even more intense heat resort outside of the sun in her corona.
The solar orbiter of ESA and NASA has taken the most detailed photo from the most extreme environment in our solar system.
Our sun moves in respectable areas in the galactic sizes, but it wanes in the face of some giants. We tell you about one in this article. In the following video you can see a foretaste of what threatens him:

We destroy the solar system and unleash a gigantic supernova in universe sandbox
Hotter than the interior of the sun
The new admission of the sun from Solar Orbiter Shows various details in the resolution that has so far been hardly known. This includes the darker spots in the glowing orange or the loops of loaded particles that are thrown out of the sun along the magnetic field lines and torn back.
Above all, however, the recording of the dominant ray wreath, which surrounds the sun, captivates Your corona. With it, a mystery envelops the sun, so to speak, because to this day we do not understand how exactly the immense temperatures of the particles come about in it.
The approximately 15 million degrees Celsius at the core, where the merger takes place, are common and logical (extreme pressure). But the bubbling, steadily waving surface of the gas ball reaches only a few thousand degrees, while above, in the Korona 100 to 1000 times higher values can occur.
The outer atmosphere of the sun is extremely thin. But exactly how this can heat up in a ratio in the vacuum is currently the subject of investigations.
Today's models manage to explain the temperatures of up to 40 million degrees, i.e. hotter than in the core of the sun. However, the mighty magnetic field of the star is probably playing an important role here (via Max-Planck-Institut).
On the ESA website Can you look at the photo in original resolution and even take a closer look at some details including information via click spots.
A special one Photo
The term photo can be misleading. In any case, it conceptually does not impose the complexity of the task of the spatial probe the respect that deserves it.
Because the Extreme Ultraviolet Imager
The Solar Orbiter has made more than 200 individual shots that were then combined to form the overall picture-a common method that was used, for example, when recording the Andromeda galaxy by Hubble.
Furthermore, the colors were practically translated into the spectra visible to us. Because our eyes cannot dissolve these details in the sun by nature – a look at the sky on a cloud -free day quickly shows why. The extremely high -energy wavelengths were quasi down so that we can recognize structures and credible colors.
Who now thinks: quite impressive our sun, If you look into the past, this could truly stall your breath. Because our sun has let go of huge storms in the past.
Disduds such as the Solar Orbiter show how successful science projects from NASA and ESA can be. However, the former is faced with surrounding changes-its likely new boss, the multi -illiarist Jared Isaacman, has the quasi-unable to do.
Together with the Parker Solar Probe the orbiter should continue to examine the sun in the coming years, as well as the Ultraheiße Korona. Because not only the latter is one of the facets of our central Gestirn, about which we still have a lot to learn.
Findings on the sun also make us better understand processes in stars – which in turn benefits all astronomy.
