Object 177: Low

Spica in the constellation Virgo is a well-studied binary star system that also ionizes the interstellar gas that surrounds it.

The Fourcade-Figueroa Galaxy is another example of a very flat disk galaxy seen edge-on from Earth, but that's not the only thing that makes this galaxy unusual.

The gravitationally lensed quasar SBS 1520+530 has been used in a unique way to measure the Hubble constant, but the derived value is rather low.

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.
