    Hydroxyl (OH) Seen for the First Time in an Exoplanet Atmosphere

    The molecule hydroxyl (HO) is common on Earth, but astronomers have not yet determined how abundant it is on other worlds. For the first time, astronomers have conclusively detected it in the atmosphere of an ultra-hot Jupiter, WASP-33b. WASP-33b is a strange exoplanet. 400 lightyears away from us, the planet is known as an ultra-hot …

    When we realize that patterns don't exist in the universe, they are a template that we hold to the universe to make sense of it, it all makes a lot more sense.
