Worm Moon HDR

Today's full moon, called a worm moon, photographed with a telescope and several images stitched together into one image.

At a full moon, the sun illuminates the lunar surface directly from the front, which hides shadows and makes it more difficult to distinguish topographical details such as craters and mountain walls. The use of HDR photography (High Dynamic Range) and stacking (combining many images) is therefore crucial to highlight geological contrasts and mineral variations that are otherwise lost in the bright light.

Geological details at a full moon

Beam systems: At a full moon, bright beam systems appear most clearly, for example from the crater Copernicus. These consist of material (ejecta) that was thrown out during a meteorite impact.

Albedo and minerals: The contrast between the light, calcium-rich highlands (anorthosite) and the dark, iron-rich oceans (basaltic maria) becomes extremely clear. By saturating the colors in an HDR image (so-called "Mineral Moon"), chemical differences in the soil can be visualized.

Bright Craters: Craters with high albedo, such as Aristarchus, shine brightly and can even be seen with the naked eye.

99% moon and the bird

The full moon is slowly rising in the sky, well, almost full, 99% behind a tree with a blackbird sitting at the top.

Tomorrow, 3/3, a total lunar eclipse will occur. The eclipse will be completely visible over northeastern and northwestern North America and the central Pacific Ocean and will be visible rising over large parts of Asia and Australia and setting over North and South America, unfortunately not from Sweden.

Like glowing jewels and Starry Sky

A beautiful view of the coast of Väddö, Sweden. On the ground, algae and seaweed stuck in the ice fluoresce like glittering jewels thanks to UV light. A cold night with beautiful Icelandic scenery and low water. In the sky, the bright star Sirius is also reflected in the water. Sirius, often called the Dog Star, is the brightest star in the night sky with an apparent magnitude of -1.46. Located in the constellation of the Great Dog (Canis Major) and only 8.6 light-years away, it is one of Earth's closest neighbors. It is part of a double star system (Sirius A and B) and is easy to find in the winter sky by extending Orion's belt. The planet Jupiter also shines as a bright star high in the center of the image. To the right, the constellation Orion is visible. Between Orion and Jupiter, our Milky Way galaxy is seen as a faint band.

We live on a beautiful planet.

Let's take care of it and each other - stop these insane wars and misery. It is up to us, the people!
