This Mind-Blowing Photo Shows a Skydiver Transiting the Sun

It was an extremely challenging shot to pull off.

Our sun, winner: Active Region of the Sun’s Chromosphere by James Sinclair

This photograph from Utah in the US shows the #chromosphere, the most picturesque part of the sun. Composed of hydrogen and helium plasma, it is manipulated by the intense and tangled magnetic fields of the sun. The chromosphere does not just change day by day, it changes second by second, which is why solar astrophotographers become obsessed with it.

October 3, 2025 — We had been having quit a lot of trouble lately, recording data and reproducing images of Sun with prominences. There was some early success but even those images were a struggle to produce. Taking a look at suggested camera settings found in an article on solar imaging, one thing stood out — gain! We had nudged the camera’s gain setting upward and that’s not helpful and certainly not recommended; the setting should be very low or even zero! A few adjustments in data capture parameters was all it took to make a big difference in image processing and results!

Sun’s northwest quadrant, as recorded in hydrogen-alpha light. Visible are several filaments, as three prominences appear along the star’s limb. The “peach fuzz” appearance of the edge of the solar disk is caused by the presence of innumerable spicules or small prominences.

We’re very pleased with Barlow-boosted views, shown here, though we’re still having some issues with achieving even lighting across whole-disk views — just can’t seem to get them tuned right with the Coronado SolarMax III. Visual observing was also very good, especially with the TeleVue 10mm eyepiece. October 3 conditions: Clear sky, temperature of 74°F, light southeast wind.

MPS Göttingen Aug 27

‪Here are some great shots from our #GREGORSolarTelescope observation campaign in July. Peering into the #photosphere and #chromosphere, we caught several emerging active regions – and a #flare! This will help us study the plasma dynamics in active regions and how energy builds up to create a flare.

Last year, #ISRO 's solar probe #Adiyta-L1 witnessed a X6.3 #flare and captured 1st images from the #chromosphere. Published today by scientists led by #IUCAA and including #MPSGoettingen in #TheAstrophysicalJournalLetters. More here: https://www.mps.mpg.de/8324638/news_publication_24282801_transferred?c=6775 ☀️🔭

Solar Probe Aditya-L1: Explosive Debut in Space

When the Sun hurled enormous amounts of radiation into space in an explosive eruption on February 22 of last year, the Indian space probe Aditya-L1, launched a few months earlier, was watching closely – and thus captured the first images of such a flare in the lowermost solar atmosphere. Today, a team of researchers led by the Inter-University Centre for Astronomy and Astrophysics (India) presents the analysis of the observational data in the journal The Astrophysical Journal Letters. The Max Planck Institute for Solar System Research (MPS) in Germany is also involved in the publication. The observed category X6.3 flare was one of the most powerful of the past year; a few months later, similarly strong flares were accompanied by spectacular auroras visible even in southern Europe. The new observations help to understand how flares originate and propagate in the different layers of the solar atmosphere.

The Sun in H-Alpha light (656.23 nm), 22 august 2024. Prominences.

A couple of images I did manage to save from a session during a quite bad morning for imaging the Sun, due the poor seeing and the sky transparency. I did like the results, though.
