NASA's Curious Universe

Normal matter—the kind that makes up our home planet and everything we can see—adds up to just five percent of the known universe. The other 95 percent is dark matter and dark energy. NASA’s Nancy Grace Roman Space Telescope will settle essential questions about this dark side, especially dark energy, one of the biggest mysteries in all of science. In this encore presentation, hear how NASA astrophysicists study dark matter and dark energy and why they are making scientists reconsider our basic understanding of the universe.

Take a deep dive into the science of NASA’s Nancy Grace Roman Space Telescope with Julie McEnery, Roman's senior project scientist. Learn why Roman’s survey data will be so detailed that they could cover a 4K screen the size of dozens of city blocks and why Julie says she doesn’t hope Roman changes our understanding of the universe—she knows it will.

What makes NASA’s Nancy Grace Roman Space Telescope a powerful tool with an unprecedented wide view of the cosmos? NASA engineers who designed, built, and tested Roman pop the hood to explain the unique technology inside. Go inside the huge NASA clean room where Roman was built, and get an up-close look at the testing campaign that ensures Roman will succeed in the cold, inhospitable conditions of space.

NASA’s Nancy Grace Roman Space Telescope is on a quest to discover planets outside our solar system. NASA scientists Bertrand Mennesson and Vanessa Bailey explain how Roman’s wide view will spot as many as 100,000 new exoplanets in a galactic census that will change how we understand planetary system formation. And we’ll learn about an experimental camera that will allow scientists to take direct pictures of Jupiter-sized exoplanets around Sun-like stars – and analyze their atmospheres.

Meet NASA’s newest space telescope: Roman. With similar resolution to Hubble but a field of view 100 times larger, the Nancy Grace Roman Space Telescope will settle essential questions in astronomy. NASA scientists Josh Schlieder and Alina Kiessling explain how that wide view will help us understand dark energy, one of the most puzzling mysteries in space. We’ll also meet Nancy Grace Roman, who joined NASA at the dawn of the space age and pushed for large space telescopes, which have revolutionized our understanding of the universe.

In its mission to explore the unknown in air and space, NASA ends up inventing a lot of new things. Then, the agency “spins off” those inventions to companies that produce products to make our lives easier and safer here on Earth. From memory foam mattresses and cordless power tools to wireless headphones and dating apps, NASA Technology is all around you, even if you’re not an astronaut.

NASA’s robotic explorers are looking for signs of ancient life on Mars. In its five years and counting on the surface of the Red Planet, the Perseverance rover has collected dozens of rock samples, including tantalizing features that could be signs of past life. Scientists want to keep studying Mars. That’s why NASA plans to send a fleet of next-generation helicopter drones and—one day—astronauts. In this episode, catch up on Perseverance’s biggest discoveries with project scientist Katie Stack Morgan and fly along with Håvard Grip, the pilot for the first-ever flight of NASA’s Ingenuity helicopter.
