Object 67: The Weird Sphere
21/02/2022 Duración: 12minThe abnormal-looking globular cluster Messier 71 is unusual in that its stars contain an excessive amount of heavy elements and in that it is being gravitationally shredded by the Milky Way.
-
Object 66: This Episode Brought to You by the Letter B
07/02/2022 Duración: 14minThe binary star system b Centauri contains an exoplanet named b Centauri b that, despite its confusing name, has changed astronomers' perspectives on how and where planets can form.
-
Object 65: The Infrared Twin
24/01/2022 Duración: 10minEven though HD 106252 has an exoplanet orbiting it, astronomers are much more interested in the fact that HD 106252 looks very similar to the Sun.
-
Object 64: An Actual Use for Einstein's Famous Equation
10/01/2022 Duración: 11minVER J0521+211 is a distant galaxy that produces gamma rays with such high energy that, when the gamma rays hit the Earth's atmosphere, the photons transform into electrons and positrons.
-
Object 63: A Rant About Variable Star Classifications
27/12/2021 Duración: 09minUX Ari is an RS CVn type variable star system, which is a confusing way to classify variable star systems but which means that UX Ari contains two stars very close together with complex, interacting magnetic fields that produce all sorts of weird effects.
-
Object 62: Imaged Before the Hubble Space Telescope Was Fixed
13/12/2021 Duración: 08minNGC 7457 was one of the first things imaged by the Hubble Space Telescope, which meant that the images of it were relatively blurry, but this is not the most interesting fact about this lenticular galaxy.
-
Object 61: Greater Than One
29/11/2021 Duración: 13minSPT-CL J0546-5345 is an abnormally large cluster that formed very quickly after the Big Bang, which places some strong constraints of models of the formation and evolution of the universe.
-
Object 60: Conclusively Inconclusive
15/11/2021 Duración: 09minUM 425 could be either a pair of very similar quasars at the same distance from Earth or a single quasar that has been gravitationally lensed so that it appears twice in the sky.
-
Object 59: Do Not Confuse With VV Cephei
01/11/2021 Duración: 07minVW Cephei is an eclipsing binary star system containing two stars that are so close that they share an outer gas layer.
-
Object 58: Insert Guitar Riff Here
18/10/2021 Duración: 10minChi Cygni is a Mira-type variable star with some of the most extreme variations in brightness among any variable stars in the sky.
-
Object 57: One of 57 Varieties of Active Galactic Nuclei
04/10/2021 Duración: 12min3C 147 is not the first object ever identified as a quasar, but it is sort of one of the first two objects ever called a quasar.
-
Object 56: The Next Best Thing to an Exoplanet
20/09/2021 Duración: 09minAstronomers may not have found an exoplanet orbiting the star HD 191089, but they found the next best thing.
-
Object 55: The Quiet Kid on the Edge of the Playground
06/09/2021 Duración: 09minThe WLM Galaxy is located at the edge of the Local Group where it is relatively unaffected by everything happening around the Milky Way and the Andromeda Galaxy.
-
Object 54: Build Your Own Hypothesis At Home
23/08/2021 Duración: 10minJets of gas that are several light years long are emerging from the blue supergiant MWC 137, and no one knows why.
-
Object 53: Fortified with Iron
09/08/2021 Duración: 09minMost globular clusters are among the first stars to form in the universe, but the globular cluster NGC 6352 seems abnormally young in comparison.
-
Object 52: The 10 Year Long Discovery
26/07/2021 Duración: 10minIt took 10 years of observations for astronomers to determine that the star HD 154345 had a Jupiter-like exoplanet orbiting it.
-
Object 51: Swipe Right for Gamma Rays
12/07/2021 Duración: 09minWhile the gamma ray burst GRB 090926A itself might be interesting to some astronomers (particularly desperate gamma ray astronomers), the interstellar gas between the burst and Earth may be even more interesting.
-
Object 50: It's Blue but not Blueberry
28/06/2021 Duración: 11minIC 10 is a nearby starburst, a type of galaxy that is forming stars at a very high rate (for its size) that should not be confused with the fruit flavored candy.
-
Object 49: Big in the South
14/06/2021 Duración: 08minThe cluster of galaxies Abell S1063 was only reported as a discovery in the 1980s, but it has attracted a lof of attention because of how it gravitationally distorts the light of galaxies behind it.
-
Object 48: It's Too Obvious To Say It's Complex
31/05/2021 Duración: 09minThe S254-S258 Complex is a chain of ionized gas bubbles connected by a filament of cold interstellar gas and dust where star are forming in a complicated (or possibly complex) way.
