At the center of our galaxy lives a supermassive black hole called Sagittarius A*. 🔭 Amanda Peake, a PhD candidate at the MIT Kavli Institute, explores Sagittarius A*, the supermassive black hole at the center of our galaxy. Astrophysicists are deeply fascinated by it because it controls our entire galaxy. The Sun is in orbit around it, and everything in the Milky Way is arranged in a spiral around the massive black hole at the center. #BlackHole #SpaceX #SpaceTok #SpaceFacts #ScienceExplained

We tested the five second rule, and the microbes won. 🍎🦠 @Alex Dainis 🧬🔬 that even after just two seconds on a seemingly clean floor, bacteria were already on the move. Some bacteria have genes that produce sticky proteins and moisture-protecting coatings, allowing them to latch on fast. The verdict? Even a quick drop can lead to contamination. #Microbiology #Experiment #STEM #ScienceTok #LearnSomethingNew #EverydayHacks

How tough can a microscopic animal be? Dr. Chris Mason, Professor of Physiology and Biophysics at Cornell University explains that tardigrades, microscopic “water bears” found in soils around the world, can survive heavy radiation and the vacuum of space. Scientists have also taken genes from tardigrades and put them into human cells to recreate that radiation resistance. #Science #Biology #ScienceFacts #ScienceTok #PopularScience
