How can we measure some of the most energetic events in the universe?  This month, we’re exploring the new science being carried out by NuSTAR, a space-based high-energy x-ray telescope.  Plus, we’ll find out why being outside the goldilocks zone might not mean there’s no chance of life, as it seems other sources of heat may make even more planets and moons good places to look for biochemistry...

    01:13 - X-Ray Astronomy and the Nuclear Spectroscopic Telescope Array

    The Nuclear Spectroscopic Telescope Array, or NuSTAR, is a new space-based X-ray telescope, which will be able to observe of some of the most violent and energetic objects in the Universe; including black holes and active galactic nuclei. We find out more...

  • 15:35 - How do we know Martian meteorites are from Mars?

    Hi there all, love the suite of shows! There are a number of meteorites which astronomers classify as Martian. First of all, how do we know they come from Mars? Secondly, a few months ago, there was an article on the Naked Astronomers about a discovery on Mars itself in...

  • 22:16 - How long would a round trip to the centre of the galaxy and back take?

    Given the vast size of the Milky Way, its likely that the only practical method of exploring it will be with automated probes along the lines of the Voyager spacecraft. With that assumption in mind, I have a couple of questions, A) With today's best propulsion technology, how ...

    25:52 - How the Moon was Made

    A new theory about the birth of the moon has the Earth spinning faster than we first thought...

  • 31:56 - Explaining Extra Infrared Emissions

    There is a mystery surrounding the amount of infrared light that bathes the universe –the so called cosmic infrared background radiation. It’s been detected by a number of space based telescopes, but with clusters of higher intensity than could be accounted for by all known gal...

  • 41:21 - How can energy escape a black hole?

    Hi Naked Scientists] I have listened to pretty much all your podcasts, and have built up a lot of dumb questions, and knowing the only dumb question is the one not asked, I have loaded up. (I apologize if any of these have been covered, or if I should have figured them out.) ...

  • 42:14 - How does gravity distort time?

    Hi Naked Scientists] I have listened to pretty much all your podcasts, and have built up a lot of dumb questions, and knowing the only dumb question is the one not asked, I have loaded up. (I apologize if any of these have been covered, or if I should have figured them out .)...

    47:18 - Going Underground - Extending the Habitable Zone

    The "Habitable Zone" around a star is the region in which water can remain liquid, and we think life my exist. New research shows that, if we look below the surface, many more planets may harbour biochemistry...

  • 54:47 - Why is gravity weaker at the centre of the Earth?

    As we progress down to the very centre of the core of the Earth, why does gravity weakens while gravity should increase toward an object? And why does pressure take over? Best regards, Muhammad al-Hakeem
