Though researchers continue to hunt for the mysterious Planet 9, experts have discovered evidence that another planet, residing between Uranus and Saturn, “escaped” billions of years ago.
The research, published in the scientific journal Icarus, suggests that an “ice giant” was “kicked out” in the early days of the solar system by unknown forces.
"We now know that there are thousands of planetary systems in our Milky Way galaxy alone," the study’s lead author, Carnegie Mellon University researcher Matt Clement said in a statement. "But it turns out that the arrangement of planets in our own solar system is highly unusual, so we are using models to reverse engineer and replicate its formative processes.

What Do Meteorites and Chondrites Tell Us About Our Solar System?
Meteorites come from a variety of sources, like the Moon, Mars, and asteroids. Some of the oldest meteorites have come from planetesimals like the ones that formed the planets. The fact that we can determine their ages from radioisotope dating means that we can study their features to learn what was happening when they formed.
In this way, meteorites help provide us with a timeline for the formation of the planets by constraining various processes.

Our Solar System: What's a Protoplanetary Disk?
Molecular clouds are seen throughout the galaxy. They are cold, dark, giant regions, with condensates of dust and molecular gasses. They can be over 200,000 astronomical units in size. These molecular clouds serve as nurseries for the creation of new stars.
When small perturbations in the motion of the gas and dust in these clouds happen to cause the density to get sufficiently high in a region, then that area begins to collapse under its own mutual gravitational attraction. It's then called a cloud core.
While you're here, how about this:
7 Clues to Understand How Our Solar System Formed
To answer these questions, we need to understand how the solar system was formed. We weren't there for the formation of the solar system, but over the years we have found some clues. We need to piece these clues together to come up with a scenario that best explains the facts.
The solar system is more than just an arrangement in space. It is also an arrangement over time—vast amounts of time—which means that we need to look back in time. Traveling backwards in time allows us to explain the key features of the solar system that we have been ignoring or taking for granted.
Nelson planning commission sets solar ordinance for public hearing | Latest News | newsadvance.com
Solar panels at Winton Farm, a country club and golf course in the Clifford community of Amherst County, helps Waukeshaw Development, the property's owner, with keeping electric costs lower, according to Dave McCormack, who heads the Petersburg-based company.
The Nelson County Planning Commission unanimously set both a solar ordinance draft and nonconforming ordinance draft for public hearings in December.
Before moving the ordinances for public hearing, commissioners during the Nov. 18 meeting reviewed changes that were made to the drafts.
Hope, the UAE's first interplanetary mission, has its eye on bonus science on way to Mars | Space
The United Arab Emirates' first foray beyond Earth's orbit is going so smoothly that the nation's Hope Mars spacecraft will tackle some bonus observations before it reaches its destination, mission leaders have announced.
The Hope spacecraft launched in July and will arrive in orbit around the Red Planet on Feb. 9, 2021. There, it will study Mars' atmosphere and weather , observations that will help scientists understand how the planet's bubble of gas works.
US Funding For Solar Systems Integration & AI Applications In Solar Energy
Continuing a decades-long trend, the US Department of Energy (DOE) has put a few million dollars into further research and development of solar power technologies — $130 million, to be precise.
The goals of the funding are to “reduce the cost of solar, increase U.S. manufacturing competitiveness, and improve the reliability of the nation's electric grid.”
* * *
$130 million may sound like a lot on the surface, but in the context of the US Department of Energy budget, it’s tiny. Also, considering that the $130 million gets spread across dozens of projects, the support for each effort is probably not as significant as it seems at first glance.
