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.

    Wait For It...

    The cluster of galaxies MACS J1149.5+2223 is so massive that it has gravitationally bent (or lensed) the light from multiple things behind it, including one of the most distant galaxies in the universe and a supernova.

    Can You Find the Supermassive Black Hole?

    Can You Find the Supermassive Black Hole?

    NGC 34 (also known as NGC 17) is a chaotic-looking galaxy that formed from two smaller galaxies merging together, and it is a place where astronomers have easily found lots of stars forming in a starburst but where they have had difficulty concluding whether the galaxy also contains a supermassive black hole.

    A Possible Source of the Cosmic Rays that Gave the Fantastic Four Their Superpowers

    A Possible Source of the Cosmic Rays that Gave the Fantastic Four Their Superpowers

    The Monogem Ring, which is one of the largest sources of X-rays in the Earth's sky, was created by a supernova explosion about 86000 years ago, and the core of the star that exploded has been identified as the pulsar PSR B0656+14 at the center of the ring.

    Alpha Table

    Even though Alpha Mensae is in one of the faintest and dumbest constellations in the sky, it's an intriguing star system because it is very close to the Earth, because one of the stars is very Sun-like, and because it may contain an exoplanet or a disk of dust in orbit around that Sun-like star.

    The Golden Standard

    The Golden Standard

    The Type Ia supernova SN 2005cf was observed at multiple wavelengths for three months after its appearance, allowing astronomers to create templates of its spectrum that could be used to measure distances to other Type Ia supernovae.
