Interstellar Objects Might Outnumber Solar System Objects in the Oort Cloud
Our solar system is filled with everything from planets to rocky asteroids to small icy bodies beyond Pluto, but surrounding all of it is a diffuse halo of objects known as the Oort cloud. We haven’t directly observed the Oort cloud, but we’re pretty sure it’s there by observing the distribution of comet in our solar system. They can appear from any direction in the sky rather than just along the common plane of known solar system bodies.

Advanced Civilizations Could be Using Dyson Spheres to Collect Energy From Black Holes. Here’s how we Could Detect Them
Black holes are more than just massive objects that swallow everything around them – they’re also one of the universe’s biggest and most stable energy sources. That would make them invaluable to the type of civilization that needs huge amounts of power, such as a Type II Kardashev civilization. But to harness all of that power, the civilization would have to encircle the entire black hole with something that could capture the power it is emitting.
This is How a Supermassive Black Hole Feeds
At the heart of most massive galaxies in our Universe, there are supermassive black holes (SMBH) that are on the order of millions to billions of times the mass of the Sun. As these behemoths slowly consume gas and dust that is slowly fed into their maws, they release tremendous amounts of energy. This leads to what is known as an Active Galactic Nucleus (AGN) – aka. a quasar – which can sometimes send hypervelocity jets of material for light-years.
