The Kuiper Belt is a collection of small, icy bodies that orbit the sun beyond Neptune, at distances larger than 30 AU (one astronomical unit or AU is the distance between the Earth and the sun). These Kuiper Belt objects (KBOs) range in size from large boulders to 2,000 km across. KBOs are leftover small bits of planetary material that were never incorporated into planets , similar to the asteroid belt .
The discoveries from the most successful Kuiper Belt survey to date, the Outer Solar System Origins Survey (OSSOS) , suggest a sneakier explanation for the orbits we see. Many of these KBOs have been discovered to have very elliptical and tilted orbits, like Pluto .
Quite a lot has been going on:
'Extreme' Kuiper Belt Objects Cast Doubt on Hypothetical Planet Nine | Astronomy | Sci-News.com
In 2016, Caltech astronomers Konstantin Batygin and Mike Brown proposed a strange alignment of icy Kuiper Belt objects (KBOs) on the outskirts of the Solar System could be explained by a massive planet — dubbed Planet Nine — orbiting eccentrically beyond Neptune. Since then, scientists have been busy gathering evidence of its existence. But does Planet Nine actually exist?

Collision of galaxies may have spurred our solar system's formation - Reuters
A star-formation binge in the Milky Way spanning the time when the solar system was born more than 4.5 billion years ago was apparently precipitated by the collision between our galaxy and a smaller one called Sagittarius, scientists said on Tuesday.
Such collisions typically do not involve stars smashing head-on, they said, but can foster conditions for star formation by, for example, amping up the amount of gas in a galaxy or having gas clouds come together.
The Solar System Might Not Exist if There Wasn't a Huge Galactic Collision with the Milky
The Milky Way has a number of satellite galaxies ; nearly 60 of them, depedending on how we define them. One of them, called the Sagittarius Dwarf Spheroidal Galaxy (Sgr d Sph), may have played a huge role when it comes to humans, our world and our little civilization. A collision between the Milky Way and the Sgr d Sph may have created the Solar System itself.
The Sagittarius Dwarf Spheroidal Galaxy was discovered in 1994, and at the time astronomers thought it was the closest dwarf galaxy to the Milky Way. Sgr d Sph is currently about 70,000 light years away from Earth. It travels in a looping polar orbit around the Milky Way.

"We will work with Mercer with their engineering school, and with students from Mercer to lead the project and install the solar panels on each of the houses," said Ivey Hall, executive director of Macon Area Habitat for Humanity.
Habitat for Humanity of Macon plans to complete the project by 2021 to help homes become more energy-efficient.

SAN ANTONIO – Whether you are a homeowner or a business owner, if you have solar panels on the roof, it's important to regularly check the general condition of those panels, experts say.
To ensure your panels have longevity, South Texas Solar Systems has provided four tips on how to maintain your solar panels properly.
Super Small-Scale Solar with a Portable Generator and 100-Watt Panel|MOTHER EARTH NEWS
Using the generator. The power station’s two AC plugs and four USB ports make it easy to plug in and charge away. It has a handy LED display showing its percent charged, which lets us know when we need to get it back to the solar panel as well as how much each of our gadgets uses.
We’ve learned that the LEDs use next to nothing over several hours — maybe a percent. The cellphone uses almost as little, while the computer will drain a few points over a couple hours. My Ryobi tool battery charger drains the power station rapidly — maybe 40% for one battery.
