Object 87: The Fake Sphere
28/11/2022 Duración: 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 Duración: 12minThe red dwarf HD 260655 has two large, hot, rocky planets orbiting very close to it.
-
Object 85: The Swedish Stellar Superstore
31/10/2022 Duración: 12minAs the largest open cluster that anyone has found in the Milky Way, Westerlund 1 contains a lot of rare and weird stars.
-
Object 84: Eccentricity
17/10/2022 Duración: 09minThe evolved red star HD 214362 is orbiting the center of the Milky Way in a very eccentric way (as in either its orbit is a very elongated ellipse or its orbit is just plainly strange).
-
Object 83: Number 1 in 1970
03/10/2022 Duración: 13minIn 1970, the quasar 4C 05.34 was the most distant known object in the universe, but this is not the only interesting fact about this object.
-
Object 82: Officially Peculiar
19/09/2022 Duración: 09minA large mass of gas fell into the lenticular galaxy NGC 3593 about 2 billion years ago, and this gas both changed the appearance of the galaxy and also created new stars that now orbit the galaxy in the opposite direction from the older stars.
-
Object 81: Unusually Shocking
05/09/2022 Duración: 09minWhat may be most interesting about the pulsar PSR J2124-3358 is not that it is spinning very rapidly but that stellar winds from the pulsar have collided with the interstellar medium, producing a glowing bow shock.
-
Object 80: The Confusing and Controversial Names Episode
22/08/2022 Duración: 10minThe star WR 124 (also called Merrill's Star, although that name ignores two of the people involved in the discovery) is a really hot Wolf-Rayet star that has produced the surrounding nebula M1-67 (which has no relation to Messier 1) and that is hurling through the Milky Way in an unusual direction at an unusual speed.
-
Object 79: The Magic of Circumstellar Semantics
08/08/2022 Duración: 11minThe star HD 131835 had a circumstellar disk of dust and gas that technically is neither a debris disk nor a protoplanetary disk but instead some sort of weird hybrid of these two things.
-
Object 78: A Dwarf Galaxy with Something for Everyone
25/07/2022 Duración: 12minLocated within the Local Group, the dwarf galaxy IC 1613 has been popular with professional astronomers for a variety of reasons, and it is also a notable albeit difficult-to-see amateur astronomy object as well.
-
Object 77: Another 90's Gamma Ray Flashback
11/07/2022 Duración: 10minGRB 980326 was the first gamma ray burst to be associated with a supernova, which was truly groundbreaking even if the astronomers who discovered it were probably using Netscape at the time.
-
Object 76: A Modern Non-Comet
27/06/2022 Duración: 08minSakurai's Object was discovered in 1996 by the amateur astronomer Yukio Sakurai, who had been searching for comets but who had instead found a dying star that had brifly undergone a final burst of fusion, causing it to increase dramatically in brightness.
-
Object 75: The Completely Unconcerned Open Cluster
13/06/2022 Duración: 09minThe open cluster NGC 3680 is 1.4 billion years old, making it unusually long-lived for such a cluster.
-
Object 74: The Brightest Star on the Argo
30/05/2022 Duración: 12minAs the second brightest star in the night sky, Canopus is associated with many different myths, yet as the closest yellow supergiant to Earth, the star is also scientifically important.
-
Object 73: A Very Distant Infrared Smudge
16/05/2022 Duración: 14minThe hyperluminous infrared galaxy IRAS 10214+4724 was the most distant infrared object seen by astronomers in the 1980s.
-
Object 72: No Face Masks Are Needed for Monocerotis
02/05/2022 Duración: 08minGX Monocerotis is a evolved star near the end of its life that is expelling its outer gas layers, and because the star is in orbit in a binary star system, those gas layers have formed a spiral pattern.
-
Object 71: The Black Hole That Didn't Get Its Morning Coffee
18/04/2022 Duración: 09minThe center of the barred spiral galaxy contains multiple regions where stars are forming as well as an inactive supermassive black home that needs some caffeine.
-
Object 70: The Uncredited Star
04/04/2022 Duración: 08minEta Aquilae was the first Cepheid variable ever discovered, but this class of stars was named after Delta Cephei instead.
-
Object 69: How To Avoid Photobombing Asteroids
21/03/2022 Duración: 11minThe North Ecliptical Pole points to a location perpendicular to the plane of the Solar System, which makes it a unique place for certain types of astronomical observations.
-
Object 68: Reflections in Quotation Marks
07/03/2022 Duración: 09minThe spiral galaxy NGC 6814 is a source of strong but variable X-ray emission that astronomers are using to measure the mass of a supermassive black hole at its center.
