Object 170: Don't Forget the Feedback

George"s Random Astronomical Object ·

2026/03/02

NGC 2639 may look like an ordinary spiral galaxy, but it contains an active galactic nucleus with jets of gas that have emerged from that nucleus in four different directions, which is, to use the technical term, quite weird.

Object 169: No Longer a Suspect

George"s Random Astronomical Object ·

2026/02/16

LGS 3 (also known as the Pisces Dwarf Galaxy) is a nearby but faint dwarf galaxy that has provided some interesting clues as to how stars formed in the early universe.

Object 168: A Very Good Looking Scientific Footnote

George"s Random Astronomical Object ·

2026/02/02

While not many professional astronomers have spent much time looking at the open cluster Messier 103, it is still a spectacular object to see in an amateur astronomy telescope.

Object 167: Controversial Radiowaves

George"s Random Astronomical Object ·

2026/01/19

Astronomers have been studying the radiowave emission from the cluster of galaxies Abell 4038 quite intently and have provided both conventional and unconventional explanations for its origin.

Object 166: An Overlooked Cluster

George"s Random Astronomical Object ·

2026/01/05

The southern open cluster IC 2602, also known as the Theta Carinae Cluster or the Southern Pleiades, may not be as famous as some open clusters visible from the Northern Hemisphere, but it is still a good place for professional astronomers to study young stars, and it's also a good amateur astronomy target.

Object 165: A Hole in the Clouds

George"s Random Astronomical Object ·

2025/12/22

Baade's Window is an unusual hole through the interstellar dust in the Milky Way's disk through which astronomers can very clearly see the stars near the center of our galaxy.

Object 164: Not Just Any Quasar But The Quasar

George"s Random Astronomical Object ·

2025/12/08

Markarian 231 is now widely recognized not only as the closest quasar to Earth but also as a very bright ultraluminous infrared galaxy.

Object 163: Ludricous Rotation

George"s Random Astronomical Object ·

2025/11/24

The pulsar PSR J1022+1001 is one of a small subclass of pulsars named millisecond pulsars because they rotate one every few milliseconds.

Object 162: Slightly More Interesting Than a Medieval...

George"s Random Astronomical Object ·

2025/11/10

The lenticular galaxy NGC 1172 contains two different populations of globular clusters, which indicates something about the history of the galaxy.

08:14

Object 161: More Subclassifications

George"s Random Astronomical Object ·

2025/10/27

Dy Pegasi is an SX Phoenicis type variable star, and SX Phoenicis type variable stars are a subset of Delta Scuti type variable stars, and this episode explains why that is confusing but what it also actually means.

Object 160: A Spiral Galaxy Using a Non-Standard Font

George"s Random Astronomical Object ·

2025/10/13

The spiral galaxy NGC 3718 has an unusually weird spiral shape, which belies its unusual history.

Object 159: That One Very Famous Double Star

George"s Random Astronomical Object ·

2025/09/29

While amateur astronomers know that Albireo is a very spectacular-looking double star, professional astronomers are more interested in the dynamical complexities of Albireo's two star systems.

Object 158: Dark Burst

George"s Random Astronomical Object ·

2025/09/15

The gamma ray burst GRB 020819 took place in a galaxy containing so much light-obscuring interstellar dust that people initially misidentified which galaxy contained the burst.

Object 157: Something More Interesting than Three...

George"s Random Astronomical Object ·

2025/09/01

The nearby Sun-like star HD 69830 may have three exoplanets orbiting it, but astronomers seem more focused on trying to understand a hard-to-explain dust disk in the star system.

en

07:56

Object 156: Dust Puffs

George"s Random Astronomical Object ·

2025/08/18

Z Ursa Minor belongs to a class of variable stars that occasionally produce puffs of dust, but this is not the weeirdest thing about them.

en

11:21

Object 155: Pinwheel

George"s Random Astronomical Object ·

2025/08/04

The nearby face-on spiral galaxy Messier 101 is one of the most popular galaxies in the sky for astronomers to study, particularly in terms of studying the relative abundances of various elements within the galaxy.

Object 154: The Binary Star System That Needed to Go...

George"s Random Astronomical Object ·

2025/07/21

A 0535+26 is a rather unusual star system called a Be high mass X-ray binary that periodically produces bursts of X-ray emission.

Object 153: A Wolf Within a Wolf

George"s Random Astronomical Object ·

2025/07/07

Hen 2-113 is a rather unusual planetary nebula that formed not when a Sun-like star died but when a large, massive, and extraordinarily hot Wolf-Rayet star blew away its outer hydrogen layers.

08:39

Object 152: The Spiderweb Flashlight

George"s Random Astronomical Object ·

2025/06/23

The quasar PKS 2126-158 has been popular to observe because astronomers can see many different things between the quasar and Earth, including an entire cluster of galaxies, that are absorbing light from the quasar.

Object 151: A Magnetic Whale

George"s Random Astronomical Object ·

2025/06/09

Beta Ceti is a relatively close giant star where helium fusion has been triggered in its core, but it's a bit unusual compared to other stars that have reached this stage in their evolution.
