9th planet discovered?
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.

No Man's Sky players have built entire rave planets - Polygon
In late 2019, No Man's Sky developer Hello Games added a full-blown synthesizer to the ever-expanding space game, allowing fans to create their own melodies. And in 2020, explorers who are a part of the fan-run Galactic Hub group have come together to build in-game colonies where the dance party never stops, courtesy of that musical update.
Internally, fans refer to these colonies as the "Dual Rave Planets," because they are meant to complement one another, color-wise. Both are bioluminescent worlds that exist on the same planetary system, with one taking on more of a red hue, and the other more tinted toward blue.
Stars | What is an Exoplanet? – Exoplanet Exploration: Planets Beyond our Solar System
The age, distribution, and composition of stars trace the history, dynamics, and evolution of their galaxy. Stars are responsible for the production and distribution of heavy elements, such as carbon, nitrogen, and oxygen.
Different star types have different habitable zones. This is the area around a star where conditions are just right, neither too hot nor too cold for liquid water to exist on a planet’s surface. (For this reason, a star's habitable zone is often referred to informally as its "Goldilocks zone.")
Three New Books That Stare Up at the Stars - The New York Times
Marchant's story starts on the walls of Lascaux cave in southwestern France, discovered in 1940, adorned with pigment depicting animals like bulls and ibexes. Scholars have argued over the meaning of the paintings, which could have been created as far back as 37,000 years ago, with some believing they were "art for art's sake.
From here, Marchant takes the reader on a ride through Western civilization. We learn of Babylonian scholars and the ancient Greeks. Marchant details the fascinating difference between star maps used by Polynesians who settled on islands throughout the vast Pacific over thousands of years, and the approach of Western explorers like Cook.

Sweden is getting on board India's Venus orbiter mission 'Shukrayaan' with a scientific instrument to explore the planet.
Ambassador of Sweden to India, Klas Molin said Swedish Institute of Space Physics (IRF) is engaged in the venture, its second collaborative project with the Indian Space Research Organisation (ISRO).
A Start-Up's Unusual Plan to Suck Carbon Out of the Sky - The Atlantic
Stripe is one of those technology companies that controls the internet's plumbing. It makes payments-processing software that hustles money from your debit or credit card to someone else's bank account. If you've ever purchased groceries on Instacart or supported a project on Kickstarter, you've used Stripe, even if you didn't know it.
Lately Stripe has been helping to build a different kind of plumbing—physical pipes running from the open air to deep underground. In the past year, Stripe has become one of the world's largest purchasers of carbon-removal credits, devoting $1 million to extracting carbon from the sky. Last month, it began allowing its customers—the businesses that use its payment software—to buy carbon removal as well.
Elusive Internal Structure of Mars Revealed by Ancient Zircon Minerals From the Red Planet
By determining the age and hafnium isotope composition of zircons, researchers from the University of Copenhagen have shown that a population of these crystals were sourced from the deep interior of Mars. If the researchers are correct, it means that the young zircons contain information about the deep, inaccessible interior of Mars, which provides insights into the internal structure of the planet.
“Zircon are incredibly durable crystals that can be dated and preserve information that tell us about their origins. Having access to so many zircons is like opening a time window into the geologic history of the planet.” — Professor Martin Bizzarro
Radioactive elements may be crucial to the habitability of rocky planets
Home / 2020 / November / Radioactive elements may be crucial to the habitability of rocky planets
Earth-size planets can have varying amounts of radioactive elements, which generate internal heat that drives a planet's geological activity and magnetism
* * *
That’s because internal heating from the radioactive decay of the heavy elements thorium and uranium drives plate tectonics and may be necessary for the planet to generate a magnetic field. Earth’s magnetic field protects the planet from solar winds and cosmic rays.
