Enceladus is a small, volcanic, watery moon orbiting inline with Saturn's outermost ring. It's interesting as it's one of the most likely celestial bodies we know of to support life. This is due to not only the presence of liquid water, but also the presence of volcanic activity. It is also one of the only currently volcanically active bodies in the Solar System.

The TRRAPIST-1 System

The TRAPPIST-1 System is an exoplanetary system located around an ultra-cool red-dwarf named TRAPPIST-1. There are 7 planets in this system, starting with TRAPPIST-1 b, and ending in TRAPPIST-1 h, all of them rocky. Not only are they all rocky, but 3 out of the 7 are in the habitable zone of their star, these being TRAPPIST-1 d, TRAPPIST-1 e, and TRAPPIST-1 f. TRAPPIST-1 e is fascinating in particular as it is the most likely to support life, as it is theorized to have the least water. The other planets, even the ones outside of the habitable zone, seem to house an absurd amount of water based on each planet's density.

The Triangulum Galaxy

The Triangulum galaxy is a small, barless, spiral galaxy located 834.875 thousand parsecs from Earth. In fact, it's much closer to Andromeda than it is to the Milky Way. I personally find it interesting due to how it contains a small, central bar structure that fades away the further away it gets from the center. I also find it interesting as it does not have a central supermassive black hole, which may explain how the bar structure is only maintained near the center; the black hole in the center would have enough gravitational influence to create a small barred system, but not enough to influence the outermost parts of the galaxy.
