There is around a 25 year window to pinpoint this proposed new dwarf planet, because its orbit takes 25000 years to complete… which probably means that the rate at which new ones will be discovered by the @… will help us better define how empty or how full the space between Neptune and the Kuiper Belt is…

An Extreme Cousin for Pluto? Possible Dwarf Planet Discovered at Solar System’s Edge
A small team led by Sihao Cheng, Martin A. and Helen Chooljian Member in the Institute for Advanced Study’s School of Natural Sciences, has discovered an extraordinary trans-Neptunian object (TNO), named 2017 OF201, at the edge of our solar system.

I don't fully get the instinct to reject and attack the Abundance book. If you think it's too small then it seems easy to "yes and" with your own ideas.
At one point they call the book a conspiracy?
It seems to me Ezra talked with people trying to install solar and got one answer. Aaron says when he talked to similar people he got a different one. that is an interesting topic to look more into!

A Terminology and Quantitative Framework for Assessing the Habitability of Solar System and Extraterrestrial Worlds
The search for extraterrestrial life in the Solar System and beyond is a key science driver in astrobiology, planetary science, and astrophysics. A critical step is the identification and characterization of potential habitats, both to guide the search and to interpret its results. However, a well-accepted, self-consistent, flexible, and quantitative terminology and method of assessment of habitability are lacking. Our paper fills this gap based on a three year-long study by the NExSS Quantitat…

"A mere decade ago, astronomers knew of just 62 #moons around #Saturn. Today the ringed #planet boasts a staggering 274 official satellites. That’s more than any other world in the solar system—and far…

A mix of long-duration hydrogen and thermal storage enables large-scale electrified heating in a renewable European energy system
Hydrogen-based long-duration electricity storage (LDES) is a key component of renewable energy systems to deal with seasonality and prolonged periods of low wind and solar energy availability. In this paper, we investigate how electrified heating with heat pumps impacts LDES requirements in a fully renewable European energy system, and which role thermal storage can play. Using a large weather dataset of 78 weather years, we find that electrified heating significantly increases LDES needs, as o…

Pronounced atmospheric scattering of shorter wavelengths,

progressively reducing solar elevation.

Got some batteries, and now my prototype solar node is ready for being tested in the field.

It's funny how these old closed down coal power plants are coming back online since PJM won't allow crypto mining onto the electric grid. Solar farms are popping up all over (confused because they could do so much better in other places than where it's cloudier than Seattle), but they aren't allowed to connect because a national company forgot to obtain a permit by some hillbilly township with a population of 3.

The role of interior dynamics and differentiation on the surface and atmosphere of lava planets
Lava planets are rocky exoplanets that orbit so close to their host star that their day-side is hot enough to melt silicate rock. Their short orbital periods ensure that lava planets are tidally locked into synchronous rotation, with permanent day and night hemispheres. Such asymmetric magma oceans have no analogs in the Solar System and will exhibit novel fluid dynamics. Here we report numerical simulations of lava planet interiors showing that solid-liquid fractionation in the planetary int…

Investigation of Martian UV Dayglow Emissions in the Southern Hemisphere during Solar Quiet-time Conditions: Insights from Multi-year MAVEN/IUVS Observations
The southern hemisphere of Mars possesses concentrated region of strong crustal magnetic fields (CMF), which generate localized magnetic anomalies that can influence atmospheric dynamics and energy deposition in the Martian thermospheric-ionospheric system. Although their effects on the atmosphere (>200 km) in the southern hemisphere are well documented, however their role in modulating the behavior of atmospheric plasma and neutrals below 200 km are poorly understood. The atmosphere at these a…
