Amid a patchwork of fields, towns, and winding rivers and roads in central Brazil stands a monolithic oval-shaped plateau. This conspicuous feature, the Serra de Caldas (also known as the Caldas Novas dome and Caldas Ridge), is perched about 300 meters (1,000 feet) above the surrounding landscape in the state of Goiás.

NASA’s James Webb Space Telescope recently imaged the Sombrero Galaxy with its NIRCam (Near-Infrared Camera), which shows dust from the galaxy’s outer ring blocking stellar light from stars within the galaxy. In the central region of the galaxy, the roughly 2,000 globular clusters, or collections of hundreds of thousands of old stars held together by gravity, glow in the near-infrared. The Sombrero Galaxy is around 30 million light-years from Earth in the constellation Virgo. From Earth, we see this galaxy nearly “edge-on,” or from the side.

Webb has found crystalline water ice in a debris disk around a young, Sun-like star called HD 181327. Based on its presence in our own solar system, scientists have expected to see it in other star systems — but haven’t had sensitive enough instruments to provide definitive proof until now.

It’s time to take a break and blast off into space! However, most of us aren’t billionaires, so we can’t take a quick 10minute break around the planet… But we can use our imagination using memes! Memes are magical because they can metaphorically make you space travel with humor and even facts. Why would you wanna go to a black void of vast nothingness when you can LOL at Jupiter looking cracked out over have too many moons to take care of? That sounds like a much better time to me. Plus, those rickety metal rockets look sus to me, who knows what kind of miscalculations can happen that has you not making it past the ozone layer. Did you know that you can’t even breathe in space? Yep, no air. No sounds. No oxygen. Just crazy stuff that we don’t even know the half off. So let’s just meme about space instead!

Objects in the sky sometimes appear
reflected as lines across water — but why?
If the water’s surface is smooth, then reflected objects would
