Sinopsis

Science discussions about astronomical objects selected at random locations in the sky.

Episodios

  • Object 107: The Red Rectangle

    18/09/2023 Duración: 10min

    The Red Rectangle (yes, the Red Rectangle) is a uniquely weird protoplanetary nebula formed by a uniquely weird binary star system.

  • Object 106: A Tale of Two Binary Star Systems

    04/09/2023 Duración: 12min

    While some astronomers are interested the globular cluster NGC 6712 because it appears to have been severely tidally disrupted by orbiting too close to the center of the Milky Way, other astronomers are interested in the cluster because it contains a couple of weird yet similar binary star systems.

  • Object 105: Super-Slow Star Formation

    21/08/2023 Duración: 11min

    Located at the edge of the Local Group, the Sagittarius Dwarf Irregular Galaxy has some of the stars with the fewest elements other than hydrogen or helium in the known universe.

  • Object 104: Going Cross-Country for a Supermassive Black Hole

    07/08/2023 Duración: 09min

    Observations with a telescope as large as the Untied States were needed to prove that J16021+3326 is a blazar, a type of galaxy containing a supermassive black hole.

  • Object 103: The Pulsar within the Cosmic Hand

    24/07/2023 Duración: 08min

    PSR B1509-58 is a relatively young pulsar that sits within a supernova remnant that looks like a giant hand.

  • Object 102: Another Ring Thing

    10/07/2023 Duración: 07min

    The spiral galaxy NGC 7552 is best known for its relatively small but bright starburst ring.

  • Object 101: Warm and Cold

    26/06/2023 Duración: 11min

    The star Eta Corvi is surrounded by a disk of dust with a rather complex structure and rather complex origin.

  • Object 100: The Self-Descriptive Nebula

    12/06/2023 Duración: 13min

    The Taurus Molecular Cloud is exactly what it sounds like it is, a cloud made of mulecular gas (mostly molecular hydrogen) in the constellation Taurus, but it is also much more than that.

  • Object 99: No References to the Six Wives of Henry VIII

    27/05/2023 Duración: 09min

    Abell 514 is a cluster of galaxies that contains six radio galaxies, and the polarized radio emission from those six radio galaxies can be used to probe the magnetic fields within the cluster.

  • Object 98: Double the Black Holes for Double the Fun

    15/05/2023 Duración: 11min

    Markarian 266 is a pair of merging galaxies that now contains two supermassive black holes.

  • Object 97: A Runaway Cow

    01/05/2023 Duración: 11min

    Mu Columbae is a bright, blue star that was ejected from the Orion Nebula in a complex gravitational interaction involving three other stars.

  • Object 96: The Proof-Of-Concept Exoplanet

    17/04/2023 Duración: 11min

    WASP-1 was the first star identified as having an exoplanet by the Wide Angle Search for Planets and thus helped to validate the techniques used by that survey.

  • Object 95: Two Non-Archaeological Relics

    03/04/2023 Duración: 08min

    The cluster Abell 168 formed from the merger of two smaller clusters, and this had many weird effects on the intracluster gas between the galaxies.

  • Object 94: So Hot and So Small

    20/03/2023 Duración: 08min

    WD 2211-495 is a small, hot white dwarf with a rather unusual amount of heavy elements in its outer atmosphere, implying that something from a surrounding planetary system occasionally falls into the star.

  • Object 93: Superthin

    07/03/2023 Duración: 09min

    UGC 7321 is an unusually flat (or superthin) spiral galaxy, which is indicative of how it has avoided gravitational interactions with other galaxies that could alter its shape.

  • Object 92: Look at This Elliptical Galaxy Instead

    20/02/2023 Duración: 11min

    The elliptical galaxy contains an abnormal amount of interstellar dust with no accompanying interstellar gas, which is weird.

  • Object 91: The Second Air Pump Galaxy

    06/02/2023 Duración: 11min

    Antlia 2, which was recently discovered orbiting the Milky Way, is the most diffuse galaxy that anyone has ever discovered up to this point in time.

  • Object 90: The Globular Cluster in a Forest Fire

    23/01/2023 Duración: 09min

    UKS 1 probably lies on the far side of the Milky Way, and its light is heavily obscured by interstellar dust, but even though it's hard to see, astronomers are still really interested in it.

  • Object 89: Relationship Status - It's Complicated

    09/01/2023 Duración: 08min

    R Aquarii could be described as one of the closest symbiotic binary star systems to Earth, but it's more complicated than that.

  • Object 88: Some Sort of Weird, Ultraviolet Freak of Nature

    26/12/2022 Duración: 11min

    NGC 6052 looks like a spiral galaxy smashing into a wall of stars, which is more or less what is actually happening.
