In our Solar System the eight known planets formed in a flat disk of dust and gas around a single star.
However, new research suggests that's not always how star systems and planets form in the Milky Way. Multiple star systems are common, which could cause "disk tearing" that creates planets with distant, chaotic orbits.

Are there more rogue planets than stars in our galaxy? | Space | EarthSky
A new study suggests there are more rogue, free-floating planets – unconnected to any star – than stars in our Milky Way galaxy. NASA’s upcoming Nancy Grace Roman Space Telescope is expected to begin finding hundreds of them.

Four Bright Planets To Shine In The September Night Sky
If you get a nice evening with clear skies and low humidity, then you may get an out of this world show.
Several planets will grace the night sky through the month of September. Jupiter and Saturn will be visible starting at dusk in the southern sky.
* * *
That is because these two worlds remain bright and beautiful throughout September yet appear highest up for the night right around nightfall.
If you notice just one bright object in the sky after sunset, it might be the very bright Jupiter. This planet outshines all the stars, plus it is near another bright planet, Saturn. You cannot miss these two if the skies are clear.
How do planets form? | Astronomy.com
How long does it take planets to form in solar systems? Since 2014, tens of thousands of volunteers have helped NASA try to answer this question by looking at telescope images of solar systems as their protoplanetary disks are still forming.
NASA’s Disk Detectives is a citizen science project that enlists members of the public to help analyze data. It was designed to discover disks of gas, rock and dust circling other stars. These structures appear early on in planet formation. So, peering into a planetary disk is like looking at a baby photo of a future solar system.

What Makes A Planet? Lessons Learned 14 Years After Pluto's Demotion
Although we now believe we understand how the Sun and our solar system formed, this early view is an ... [+] illustration only. When it comes to what we see today, all we have left are the survivors. What was around in the early stages was far more plentiful than what survives today.
In the 14 years since, however, we've made an amazing slew of discoveries. We've continued to find, identify, and characterize objects in the Kuiper belt. New Horizons visited Pluto and revealed this outer world as never before. Additionally, missions like NASA's Kepler and TESS have found thousands of new exoplanets, while independent observations have discovered an interstellar population of long-suspected rogue planets: planets without parent stars.
Industrial waste can turn planet-warming carbon dioxide into stone | Science | AAAS
At Gahcho Kué, a sprawling diamond mine in Canada's Northwest Territories, researchers are attempting to use the mine's crushed rock waste to trap carbon dioxide for eternity.
In July 2019, Gregory Dipple, a geologist at the University of British Columbia, Vancouver, hopped on a 119-seat charter flight in Yellowknife, Canada, and flew 280 kilometers northeast to the Gahcho Kué diamond mine, just south of the Arctic Circle. Gahcho Kué, which means "place of the big rabbits" in the Dënësu¸łinë language of the region's native Dené or Chipewyan people, is an expansive open pit mine ringed by sky-blue lakes.
No One Has A Monopoly On Caring About The Planet
The businesses with the biggest footprints are some of the most important allies in fighting climate change. Nicole Rycroft, Ashoka Fellow and founder of Canopy, has been transforming supply chains to save our forests for over two decades. She talked to Pip Wheaton, Ashoka's co-lead of Planet & Climate (full bios below).
Nicole Rycroft is creating new paths for big companies and their CEOs to do their part in addressing ... [+] climate change: one supply chain at a time.
Planet Hack 2020: Our Annual Hackathon Goes Virtual
At Planet, our mission is to make change visible, accessible and actionable . In 2017 we achieved that by building the world's largest satellite constellation that images the entire Earth's landmass every day.
Three years later, our platform continues to grow as we develop new ways for people to harness the power of our unprecedented dataset: tools like Planet Analytics leverage deep learning to make unique insights accessible to users around the world.
