Episodes
-
Object 105: Super-Slow Star Formation
21/08/2023 Duration: 11minLocated 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 Duration: 09minObservations 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 Duration: 08minPSR 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 Duration: 07minThe spiral galaxy NGC 7552 is best known for its relatively small but bright starburst ring.
-
Object 101: Warm and Cold
26/06/2023 Duration: 11minThe 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 Duration: 13minThe 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 Duration: 09minAbell 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 Duration: 11minMarkarian 266 is a pair of merging galaxies that now contains two supermassive black holes.
-
Object 97: A Runaway Cow
01/05/2023 Duration: 11minMu 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 Duration: 11minWASP-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 Duration: 08minThe 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 Duration: 08minWD 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 Duration: 09minUGC 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 Duration: 11minThe 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 Duration: 11minAntlia 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 Duration: 09minUKS 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 Duration: 08minR 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 Duration: 11minNGC 6052 looks like a spiral galaxy smashing into a wall of stars, which is more or less what is actually happening.
-
Object 87: The Fake Sphere
28/11/2022 Duration: 09minAlthough at first NGC 6781 may look like a spherical planetary nebula, it actually has a cylindrical shape, which has rather complex scientific implications for analyzing this object.
-
Object 86: Two Hellscapes Orbiting a Red Dwarf
14/11/2022 Duration: 12minThe red dwarf HD 260655 has two large, hot, rocky planets orbiting very close to it.
