Far from mindless predators, sharks are ancient, awe-inspiring creatures that play a crucial role in the ocean ecosystem—and they’ve been unfairly cast as villains for decades. From cartilage skeletons to teeth-shaped skin, there's more to admire about these creatures than fear.

🦈Has a fear of sharks ever made you think twice about jumping in the ocean? Fifty years after Jaws, the film that made sharks infamous, it's time to take a closer look at the real story. 👇

Text reads: “Gaseous Fuel.” There’s an illustration of the interior of a spacecraft. A thermometer is taking the temperature of a white-blue flame from a gas burner. The Milky Way is visible through the spacecraft’s windows. There’s an icon of a ring of fire surrounding water vapor in the bottom right-hand corner of the image.

💡 Cool flames—a fascinating phenomenon in combustion—were first discovered aboard the ISS in 2012 during droplet combustion experiments! Unlike typical flames, these "cool diffusion flames" burn at much lower temperatures and are invisible to the naked eye.
