What Does Space Smell Like? Scientists Uncover the Universe's Aromatic Secrets Mexico City, May 29, 2025 – A recent short video from TV Azteca Aguascalientes has sparked curiosity about the surprising scents of outer space. The video, which has quickly gained popularity, explores the findings of scientists and astronauts regarding the aroma of the cosmos. According to the video, astronauts returning from spacewalks report a distinct, intense odor. This smell has been described as a mix of "burnt meat, hot metal, and welding fumes." The video further explains that these scents are not simply random occurrences; they're linked to the chemical composition of celestial bodies. The video highlights the contrasting aromas of different planets. Titan, Saturn's moon, is said to have an odor reminiscent of "bitter almonds and gasoline" due to its hydrocarbon atmosphere. On the other hand, planet HD189733b is described as smelling of "rotten eggs" because of its high sulfur content. These findings, the video suggests, are not only interesting in themselves but also provide valuable insights into the chemical composition of the universe and the possibility of extraterrestrial life. "The investigation continues, and each new discovery brings us closer to understanding the secrets of the cosmos," the video narrates. The video's popularity underscores the public's fascination with space exploration and the mysteries it holds. The information presented is both engaging and scientifically grounded, making it a valuable contribution to the ongoing conversation about the universe.
