    At only $70, this jubilant 4x4” piece on canvas board features a triple system of red, blue and white stars. Are the circles and lines a user interface or tremendous space structures? Message me to get this cosmic view! 😊Support solo artists. Please boost and share! 🙏#ArtForSale #MastoArt #space #scifi #abstractart #geometricart

    Swipe right to see a lot more of MarsWhen our astronauts set foot on the surface of Mars, they could be treated to a panorama like this one, taken by our Curiosity rover earlier this year. Curiosity has been rolling through the Gale Crater region for more than 4,000 Martian days, exploring the Red Planet's geology from a time when it could have once been home to microbial life.Curiosity captured this view on Feb. 7, 2025, as it climbed Mount Sharp, a 3-mile-tall mountain made up of layers which formed in different eras of Martian history. By studying each layer, Curiosity's scientists can learn more about how the planet's environment changed over time from a warmer, wetter, and more Earthlike world to the freezing desert it is today. This view looks back down from the slopes of Mount Sharp into Gale Crater.Image description: A very wide panorama, split into several images, shows off a rocky Martian landscape. A rippled, reddish-brown surface dominates the foreground, with hilly slopes descending into a flat plain—the surface of Gale Crater. The far wall of the crater can be faintly seen in the distance.

    I'm not giving interviews about pre-prints that have not been through peer review yet.Yes, peer-review is deeply flawed, but it's the best we have right now. At least someone tried their best to make sure the result is sound. They may fail, but they tried.Papers before should not be covered. And if I'm asked to comment on an un-reviewed paper, I pretty much have to do the referee work myself (which I can't since a review has often several rounds).#astrodon #science #astrophysics #academia
