ALTThis computer-simulated image shows a supermassive black hole at the core of a galaxy. The black region in the center represents the black hole’s event horizon, beyond which no light can escape the massive object’s gravitational grip. The black hole’s powerful gravity distorts space around it like a funhouse mirror. Light from background stars is stretched and smeared as it skims by the black hole.You might wonder — if this Tumblr post is about invisible things, what’s with all the pictures? Even though we can’t see these things with our eyes or even our telescopes, we can still learn about them by studying how they affect their surroundings. Then, we can use what we know to make visualizations that represent our understanding.When you think of the invisible, you might first picture som...

Although there won’t be any humans aboard Orion, there will be a very important crewmember: the Moonikin! The Moonikin is a manikin, or anatomical human model, that will be used to gather data on the vibrations that human crewmembers will experience during future Artemis missions. But the Moonikin is currently missing something incredibly important — a name! There are eight names in the running, and each one reflects an important piece of NASA...
