Object 175: Counterintuitive Supernova Explosions

HD 210121 is a fairly ordinary blue star located behind a relatively thick cloud of interstellar gas and dust, providing astronomers with a unique opportinity to study that dust.

The Cepheus Flare is a nearby regions where a series of supernova explosions have counterintuitively triggered the formation of stars.

The red dwarf TOI-700 has at least four exoplanets orbiting it, and two of them are Earth-sized exoplanets lying within the star system's habitable zone.

G191-B2B is a hot white dwarf with a layer of nearly pure oxygen that has been used as a flux calibration source for one particularly famous telescope.

VY Canis Majoris is not only much, much larger than the Sun but is also ejecting blobs of gas that are forming molecules and dust.

3C 324 was once identified as a possible gravitational lens where one galaxy was bending the light from a galaxy behind it, but it turned out to be something different.

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.

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.

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.

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.
