The center of our galaxy rises from the ocean late at night off the east coast of Sweden. The center of the Milky Way is the dense core of the galaxy, located about 25,000–28,000 light-years from Earth in the constellation Sagittarius. At its absolute center is the supermassive black hole Sagittarius A* (not visible in these photos, still under the sealine), which weighs about 4 million solar masses. The area is hidden behind thick space dust and is characterized by an extreme density of stars.
Today's sun with quite a lot of activity. On the western edge of the sun, prominences are seen, also activity from sunspot 4422 which is just over the edge on the eastern side. On the surface, sunspots 4420. 4421 and 4424 etc. are seen with flares which are seen as white areas, also filaments, seen as dark streaks.
Sunspots are temporary, dark and cooler areas on the sun's surface (the photosphere) caused by strong magnetic fields. They arise because the magnetic fields inhibit the flow of energy from within the sun, making these areas cooler than their surroundings. The spots are linked to the sun's activity and are the starting point for solar storms.
And otherwise, structures in the chromosphere are seen via my Ha solar filter.
Without special equipment, the chromosphere cannot normally be seen due to the overwhelming brightness from the photosphere, but it is clearly seen through bandpass filters set to the H-alpha spectral line.
1.9 billion-year-old bedrock, limestone, and marble. Limestone bedrock refers to bedrock that is dominated by limestone, a sedimentary rock that primarily consists of the mineral calcite (calcium carbonate). This type of bedrock creates unique conditions for both plant life and landscape forms. Limestone is a relatively soft and water-soluble rock. When acidic rainwater penetrates the soil, it dissolves the limestone, creating various types of cavities.
The image at the bottom shows something called Boudinage. It is a geological structure that occurs when a relatively stiff (competent) rock is stretched and broken into smaller pieces within a more easily deformable surrounding. The result often resembles sausages lying in a row, which gave rise to the name (from the French boudin, meaning blood sausage).
In the sky, the colors of dusk can be seen, but the northern lights also emerge along with the Milky Way.
