Did a massive ice giant planet once orbit in the outer solar system? And what could evidence for such a world teach us about the original positions of Jupiter and Saturn?
The ancient Solar System was formed from a disk of gas and dust spiraling around the nascent Sun. At first, most astronomers believe, the earliest planets formed in regular, closely-packed, orbits. Soon, however, gravitational tugs from the most massive of these worlds played havoc with the regular orbits of their neighbors.

Wisconsin utilities power on 150-MW commissioned solar system
A large-scale Wisconsin’s solar project is complete and powering Madison-area households and businesses. Madison Gas and Electric (MGE) is a co-owner of the 150-MW Two Creeks Solar facility with Wisconsin Public Service (WPS). MGE owns 50 MW of the system and WPS owns 100 MW.
“We are excited that Two Creeks Solar is now generating cost-effective, carbon-free energy for all our customers,” said Jeff Keebler, MGE chairman, president and CEO. “Growing our use of renewable resources is a key strategy for achieving our goal of net-zero carbon electricity by the year 2050. The completion of Two Creeks Solar is an important step in our ongoing transition toward deep decarbonization.”

Now, this dude takes it a step further by looking at the entirety of the solar stystem. The scale does a rad job of laying out the massive distances between our planets using lights in the desert. Enjoy!

Centrica Business Solutions Completes Shelter Creek Condominiums Solar System
"As we began to review options to make our community more sustainable, it seemed natural to have solar panels installed on our roof space that spans 440,000 square feet across eight buildings," said Ronnie Rosen CCAM-HR.LS General Manager, Shelter Creek Condominium Owners' Association .
Shelter Creek Condominiums is one of the largest multi-family developments in San Mateo County and is leading the way as a sustainable community. The 1,296 condominium style homes sit on 46 acres are built around open reserve areas. Over the past decade, management has been on a mission to transform the 45-year-old facility into one of the most sustainable communities on the west coast.
Nitrogen Atmospheres of the Icy Bodies in the Solar System
This brief review will discuss the current knowledge on the origin and evolution of the nitrogen atmospheres of the icy bodies in the solar system, particularly of Titan, Triton and Pluto. An important tool to analyse and understand the origin and evolution of these atmospheres can be found in the different isotopic signatures of their atmospheric constituents.

Southgate Center flips the switch on new commercial solar system - Paso Robles Daily News
–Local real estate developer, Covelop Inc ., and the other owners of the Southgate Center in Paso Robles, flipped the switch on a newly installed 1,300 panel 500-Kilowatt rooftop solar installation. "We were very pleased to work with Wicks Solar on such a significant project, one of the largest in Paso Robles,” said Damien Mavis of Covelop, Inc.
Located at 1650 Ramada Drive, the Southgate Center is the recently renovated former Paris Precision Products building. The renovation and reposition, led by Covelop, Inc., transformed the 200,000 sf. vacant factory into a Class-A, multi-tenant light industrial facility. "The final step of our business plan was the installation of the solar system,” said Mavis.
About half of Sun-like stars could host rocky, potentially habitable planets -- ScienceDaily
Our galaxy holds at least an estimated 300 million of these potentially habitable worlds, based on even the most conservative interpretation of the results in a new study to be published in The Astronomical Journal . Some of these exoplanets could even be our interstellar neighbors, with at least four potentially within 30 light-years of our Sun and the closest likely to be at most about 20 light-years from us.
The study is authored by NASA scientists who worked on the Kepler mission alongside collaborators from around the world. NASA retired the space telescope in 2018 after it ran out of fuel. Nine years of the telescope's observations revealed that there are billions of planets in our galaxy -- more planets than stars.
