    Episode 631: Q&A 118: Are We In a New Space Race? And More... Featuring Dr Jessie Christiansen

    In this week's questions show, I talk about how we're in a new space race, and what this means for returning to the Moon. Of course, lots of follow up answers about the Fermi Paradox. Could Betelgeuse release gravitational waves if it explodes? And what is our responsibility if we are truly alone in the Universe?

    Episode 629: Should We Fly to Another Star Soon? Or Wait for Better Technology to Come Along?

    Episode 629: Should We Fly to Another Star Soon? Or Wait for Better Technology to Come Along?

    It’s hard to really wrap your mind around the vast distances between stars. The fastest spacecraft ever launched into an interstellar trajectory right now is Voyager 1. If it was directed at the nearest star, it would take tens of thousands of years to make the journey across the interstellar gulf.


    Even so, groups like Breakthrough Starshot and Icarus Interstellar are working on plans right now to try and send spacecraft to other stars, ideally within our lifetimes.


    But we can see how quickly technology is advancing all around us, from materials science to high energy physics, not to mention reusable rockets.


    It seems reasonable to ask, should we invest in an interstellar mission now, or wait a few decades or even centuries for better technology to come along which could make the trip much shorter?

    Episode 630: Betelgeuse Is Still Dimming! And We Have the Pictures to Prove It

    Episode 630: Betelgeuse Is Still Dimming! And We Have the Pictures to Prove It

    Near the end of 2019, astronomers watching the red giant Betelgeuse noted how much the star had dimmed, continuing to steadily fade for months.


    It’s a variable star, and it’s known to get dimmer and brighter, but the big surprise is that it’s still continuing to dim, recently passing magnitude 1.56 and still getting dimmer. This is unprecedented in the decades that astronomers have been watching the star.


    The world’s biggest telescopes are on the case, and the European Southern Observatory released dramatic new images of Betelguese, resolving features on the star’s surface and surrounding area showing how it’s dramatically changed over the course of 2019.

    Episode 628: Q&A 117: Why Am I So Negative About Aliens? And More... Featuring Dr. Jason Wright

    In this week's questions show, I explain why I've got such a skeptical view about the search for aliens if there might be multiple great filters, and why NASA doesn't just go back and use Apollo hardware to return to the Moon?


    Follow Dr. Wright on Twitter:

    00:40 Are there multiple Great Filters?
    02:35 Could we refuel ships in space to land on Mars
    06:01 Could we put a light on the Moon to prove what we landed there?
    08:18 Will James Webb Launch?
    09:52 What will it take to confirm signs of life?
    12:30 How long until cosmic rays die down?
    16:03 Why don't we just use Apollo hardware to go back to the Moon?
    19:46 Why am I so negative?
    22:29 Good sources of journals?
    25:43 When will you believe that it's actually aliens?

    Episode 627: We've Never Seen the Sun's Poles. That's About to Change With Solar Orbiter

    Episode 627: We've Never Seen the Sun's Poles. That's About to Change With Solar Orbiter

    On February 9, 2020, the European Space Agency’s Solar Orbiter spacecraft launched from Cape Canaveral Florida on top of an Atlas V 411 spacecraft. The spacecraft’s mission is to fly inside the orbit of Mercury, on a tilted orbit that takes it above and below the Sun, capturing images of the Sun’s poles for the first time.


    This is just a year and a half after the launch of NASA’s Parker Solar Probe, which will fly even closer. Together, the two spacecraft will measure the Sun from every angle up close, providing detailed images and insights of our closest star, to help understand how it creates and controls the giant bubble of plasma that surrounds the entire Solar System.
