Earth from Space: The fate of a giant

This Copernicus Sentinel-2 image over the South Atlantic Ocean features a close-up view of the A23a iceberg, once the world’s largest. The unusually cloud-free image shows the first signs that the iceberg will soon disintegrate completely.

If Matter & Antimatter Were Created Equally, What Symmetry-Breaking Mechanism Allowed The Dominance Of Matter We Observe Today?

The observable universe contains an overwhelming abundance of matter over antimatter, with no significant reservoirs of primordial antimatter detected

Here are the launches and landings we’re most excited about in 2026
A lot could happen in space next year, but let's get real about what actually will.

A wide view of the planet Mars fills the frame, shown as a curved, rust-colored world against black space. The bottom edge fades into darkness, marking the planet’s night side, while the upper portion is brightly lit by sunlight. Near the right side are three large, round volcanic mountains of the Tharsis region, each with a wide circular base and a darker central caldera, resembling shallow craters pressed into the surface. North of these volcanoes, stretching almost vertically across the upper right half of the planet, lies Noctis Labyrinthus and Valles Marineris: an immense system of deep canyons and fractured terrain that appears as pale, branching scars and cracks, partly softened by hazy, cloud-like atmospheric features. Near the center of the image, positioned between the volcanoes and the canyon system, a small dark oval appears against Mars’s surface. This is Phobos, one of Mars’s satellites. Its tiny size stands out sharply against the vast scale of the planet below.

There are 10 days left to leave your comment on Trump administration proposals to gut the Endangered Species Act. I know this kind of thing can feel pointless, and I'm not claiming it will change their plans. What it can do, as we saw with public lands sales, is give cover to politicians. Popularity still matters, and the ESA is incredibly popular.

Support is over 80%, at a time in this country when nothing gets 80%. It isn't perfect, but it's one of the best laws we have. It's worth protecting.

I reprocessed the image to remove hot pixels (left) and the stars (right) to make the tail easier to see.

EDIT: The starless image was updated with a cleaner version.

The same image, but with the stars removed, showing 3I/Atlas in the center, visible as a bright fuzzy object with a faint tail pointing upward.
With no stars in the image, the tail is easier to make out, it appears to be a little undulated.

The Outer Giant Planets by JWST - My final version

The image is divided into four sections, each showing one of the gas giants against a black background as seen by JWST. Filters are near infrared and have been colorised.

Top left: Jupiter. It appears as a large, round sphere with horizontal bands in shades of light brown, tan, and white. A bright white oval storm sits on the lower right side. A faint ring is visible alongside Europa, one of its satellites, which appears very bright with a star-shaped artifact.

Top right: Saturn. It has a pale beige surface with soft horizontal shading. Surrounding it is a wide, bright ring system tilted diagonally. The rings look thin and sharply defined, with multiple subtle bands of light and dark.

Bottom left: Uranus. It appears as a smooth blue-green sphere with some whitish circular clouds around the pole that is facing the observer. Surrounding it is a bright circular ring system made up of thin white lines. The rings form a bright, symmetrical halo around the planet.

Bottom right: Neptune. It is a blue sphere with slightly brighter and darker circular features on its atmosphere. It also has a thin ring system, dimmer and less defined than Uranus’s in this image, appearing as a faint double oval around the planet.

Each planet has its name printed below it in white capital letters. — The image is divided into four sections, each showing one of the gas giants against a black background as seen by JWST.

Was bezeichnend ist, es wird immer von "ein deutscher Astronaut" gesprochen. Zwei Männer sehen gleich sich, als mögliche Kandidaten. Die Medien fragen auch nicht, ob auch Astronautinnen in der Ausbildung und geeignet sind.

Warum keine Frau? Aber es ist in der Sprache schon gleich so angelegt, dass gar niemand überhaupt auf die Idee käme, eine Astronautin könnte auf den Mond fliegen.
