George's Random Astronomical Object

George's Random Astronomical Object is a biweekly astronomy podcast featuring science discussions about astronomical objects at randomly selected locations in the sky. The wide range of topics discussed in the show include stars, variable stars, variable variable stars, supermassive black holes, ultracool dwarf stars, exoplanets, howler monkeys, infrared radiation, acronyms, more acronyms, starbursts, measurements of less than 12 parsecs, jellyfish galaxies, diffuse ionized gas, and general overall weirdness.

    Strong Arm Tactics

    One of the spiral arms in the galaxy NGC 3110 is producing unusually huge amounts of new stars as well as unusually huge amounts of infrared emission.

    I Need a 2002 Pop Culture Reference

    The radio source PMN J0134-0931 created a lot of excitement in 2002 when people discovered that it was a quasar gravitationally lensed by another galaxy in front of it, they were really excited.

    Get To Know Your Ultrafaint Neighbors

    Hydrus I is a very small, ultrafaint dwarf galaxy orbiting the Milky Way that was accidentally (or, to use the technical term, serendipitously) found by the Dark Energy Survey.

    Putting It All Together

    NGC 4261 was made famous when Hubble Space Telescope observations in the 1990s showed that this elliptical galaxy contains a supermassive black hole.
