Object 149: Spaghetti Leftovers

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.

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.

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.

Wolf 1069 is another nearby red dwarf with an exoplanet, but this time, the exoplanet is more likely to harbor life than other nearby red dwarfs with exoplanets that I may have discussed in previous episodes.

The globular cluster Messier 54 is not part of our galaxy but actually the nuclear stellar core of a dwarf galaxy that has nealy been completely gravitationally torn apart by the Milky Way.

Algol-type variable affected by light travel time effect caused by two smaller red dwarfs on wide orbits; this makes the variability period of the central two stars appear to vary.

Abell 1142 is a peculiar cluster of galaxies that has formed from the merger of two smaller clusters, and its center contains nothing but gas.

SN 2002cx was the first supernova ever identified in a subclass of objects now called Type Iax supernovae.

PSR J1518+4904 is one of the very few identified double neutron stars, and it has provided opportunities to perform unique measurements on the objects.

The stars in the open cluster NGC 6253 contain abnormally large amounts of elements heavier than hydrogen and helium, and no one is quite certain why.
