The Solar System: How do we know how it formed? - BBC Science Focus Magazine

Asking questions about where we come from is one of the traits that marks us out as distinctly human. Yet this inquisitive streak hasn't always led us in the right direction, particularly when we think we are more important than we ultimately are.

The story of our quest to discover how our Solar System formed is littered with false starts, and one that astronomers are still refining.

The world's greatest thinkers originally had the Earth at the centre of creation, with the Sun , Moon , planets and stars circling around us. It's an idea that lasted for more than 1,000 years, dating back to the days of Aristotle and Ancient Greece.

Inverse Daily: The center of the Solar System?

As a kid, I celebrated the 4th of July by going to a grassy field, between a nursing home and jail, to watch the official fireworks set off along a nearby river. I grew up in New Hampshire, a state that is unfortunately known for its fireworks.

It's no coincidence that the nursing home and jail were close together — if you look at a map of many towns and cities this is often the case. Jails and nursing homes are both often designated for the cheapest, least desirable land, away from the center of town.

The collective power of the solar system's dark, icy bodies -- ScienceDaily

The outermost reaches of our solar system are a strange place -- filled with dark and icy bodies with nicknames like Sedna, Biden and The Goblin, each of which span several hundred miles across.

Two new studies by researchers at the University of Colorado Boulder may help to solve one of the biggest mysteries about these far away worlds: why so many of them don't circle the sun the way they should.

The orbits of these planetary oddities, which scientists call "detached objects," tilt and buckle out of the plane of the solar system, among other unusual behaviors.

Scientists found the center of the solar system - Tech Explorist

A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. According to the theory of general relativity, a sufficiently compact mass can deform spacetime to form a black hole.

In the search for previously undetected black holes that are billions of times more massive than the Sun, scientists from the Vanderbilt University with the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) collaboration have moved the field of research forward by finding the precise location – the center of gravity of our solar system – with which to measure the gravitational waves that signal the existence of these black holes .

Things Are Really Weird in The Outer Solar System, And We May Have Figured Out Why

Most of the Solar System is pretty well behaved, but in the distant reaches, out past the orbit of Neptune and far from the light of the Sun, things can get a little… strange. There are a bunch of rocks orbiting the Sun in patterns totally different from the objects found closer in.

Because of this apparent detachment from the rest of the Solar System, these dark, icy bodies are known as "detached objects", and astronomers have been searching for an explanation of why they act so weirdly.

Eastern Mennonite School to Install Largest Solar Power System at any K-12 School in Harrisonburg

HARRISONBURG, Va. , July 8, 2020 /PRNewswire/ -- Eastern Mennonite School has signed an agreement with Secure Futures Solar of Staunton to install and operate solar panels on its Harrisonburg campus. Together, the school's solar arrays will generate a total capacity of 136 kilowatts of power, more than any solar power system installed at a K-12 school in Harrisonburg .

The solar panels at EMS will offset nearly a third of the electricity used by the school's facilities while generating enough clean energy to run the equivalent of 15 average homes and avoid more than 141 tons of carbon dioxide pollution per year. The system is projected to be completed by the fall of 2020.

There’s more to solar systems than module capacity – pv magazine USA

While solar modules are often defined first and foremost by their capacity, higher module capacity doesn't necessarily translate to a more efficient system, or even a longer-term yield. Understanding this and reflecting this idea onto customers can be key to delivering the right technology.

* * *

Considering solar modules as a commodity is an easy trap to fall into. While DC capacity is particularly important, there's so much more to solar modules that needs to be carefully considered to ensure you're delivering the right technology to your customers. While customers care about "first cost," perhaps more so now than ever before, helping explain "total cost" and system yields can have an outsized positive impact in preservation of margin and increased revenues for your business.
