Episodios

  • Object 7: Circles within Circles

    04/11/2019 Duración: 11min

    30 Ari contains four stars and an exoplanet all arranged in a rather complex set of nested orbits.

  • Object 6: Extra Peculiar

    21/10/2019 Duración: 08min

    HD 98851 is both an Am chemically peculiar star and a delta Scuti variable star, and it has two different pulsation cycles, which makes it really peculiar.

  • Object 5: Some Unexpected Helium

    07/10/2019 Duración: 10min

    RV Octantis would be considered a run-of-the-mill RR Lyrae variable star if it wasn't for the unexpected discovery of helium in its atmosphere.

  • Object 4: A Damp Lyman Alpha Elephant

    23/09/2019 Duración: 13min

    The most interesting thing about the quasar LBSQ 0058+0155 is not the quasar itself but the galaxy between the quasar and Earth.

  • Object 3: Room Temperature

    09/09/2019 Duración: 08min

    HD 85512 is a nearby star slightly smaller and more orange than the Sun. It happens to have an exoplanet that could be close to Earth-like.

  • Object 2: Variable Variability

    26/08/2019 Duración: 09min

    HS Hydrae is a variable eclipsing binary star, which sounds more unusual than it actually is. However, it's precessing, which is not only unusual but also causes the variability to vary over time.

  • Object 1: Not the Pope

    12/08/2019 Duración: 08min

    The Leo IV Dwarf Galaxy is one of several ultra faint dwarf galaxies that orbit the Milky Way. Galaxies like this are weird relics of when the universe first formed; they contain very old stellar populations and abnormally large amounts of dark matter.
