🎧 The Search for Dark Matter

Up to 95% of the universe is made up of mysterious Dark Matter and Dark Energy. We can see the gravitational influence of Dark Matter and attribute the accelerating expansion of the universe to Dark Energy, but both remain invisible to direct detection. We’ll explore one of Astronomy’s great mysteries in the U.S. National Science Foundation’s “Discovery Files”. “So, we know the dark matter is there because we can detect its presence through how it's affecting other objects, through gravity. Dr. Joe Pesce is an astrophysicist with the U.S. National Science Foundation. The agency supports both scientists and the incredible tools they use for discovery. “It's very important because it's a gravitating mass. It's even more important because some 95% of the material that's out there is something that's completely unknown.” New tools and a comprehensive scientific approach will be needed to definitively reveal Dark Matter. Jointly funded by the U.S. National Science Foundation and the Department of Energy's Office of Science, The NSF-DOE Vera C. Rubin Observatory aims to repeatedly capture the entire visible southern sky with unparalleled completeness, detail and speed, and perhaps reveal deeper understandings of Dark Matter and Dark energy. The observatory is expected to yield a staggering number of new discoveries: billions of stars and galaxies, millions of asteroids, comets and interstellar objects as they pass across the nights’ sky. Not to mention new phenomena that are sure to keep researchers busy for years to come.
