    Henrietta Leavitt and the end of the universe

    Henrietta Leavitt and the end of the universe
    In the early 1900s, Henrietta Leavitt made one of the most important discoveries in the history of astronomy: a yardstick to measure distances to faraway stars. Using this tool, scientists eventually transformed our understanding of the universe. They realized space was expanding, that this expansion was accelerating, and that ultimately, everything will end. This episode originally ran on June 30, 2021.

    What The Universe Is Doing RIGHT NOW

    What The Universe Is Doing RIGHT NOW
    A century ago, astronomers were locked in a debate about the scope of our universe. Were we it?

    The answer is no. There are other galaxies beyond the Milky Way, and they are speeding away from us. Answering that question left astronomers with an even bigger puzzle. Why is everything sprinting away from us and what does that mean for the center of the universe? Today, Scientist in Residence Regina G. Barber brings back astronomer Dr. Vicky Scowcroft for the final episode in our series on cosmic distances and humanity's place in the universe. It's a big one: The mystery of our expanding universe.

    SPACE WEEK: The Mystery Of Dark Energy

    SPACE WEEK: The Mystery Of Dark Energy
    It's Space Week on Short Wave! Today, an encore of our episode on dark energy. This mysterious energy makes up almost 70% of our universe and is believed to be the reason the universe is expanding. Yet very little is known about it. To figure out what we do know — and what it could tell us about the fate of the universe — we talk to astrophysicist Sarafina Nance.

    What Is Dark Energy? Physicists Aren't Even Sure

    What Is Dark Energy? Physicists Aren't Even Sure
    Dark energy makes up almost 70% of our universe and is believed to be the reason the universe is expanding. Yet very, very little is known about it. To figure out what we do know — and what it could tell us about the fate of the universe, we talked to astrophysicist Sarafina Nance. She studies cosmology, a field that looks at the origin and development of the universe.
