The "bump" near the center is Olympus Mons, the largest volcano in the solar system! If placed on Earth, it would be three times taller than Mt. Everest and cover a land area equivalent to France!

Tidally Locked

Commission for @foxgirlchorix of two moons of her giant planet Kizudea:

Kolayut, the homeworld of the catgirls

Astharulo, the homeworld of the foxgirls

also, Taruvidi, a large as-yet uninhabited satellite planet.

On the right, we orbit Kolayut and can see Astharulo and Taruvidi behind Kizudea. On the left, we orbit Astharulo and can see Taruvidi in front of Kizudea and Kolayut behind it.

Quick and Easy Worldbuilding

Decided the other night I'd make a terrestrial planet with oceans, an ice cap, and some continents.

First, I drew a shitty little map in Krita...

Then I made a sphere in Blender...

Slapped the map onto the sphere as an image texture, then made some smaller spheres for moons...

Went to the Render dropdown and selected the Image option...

...and Voila!

👏👏👏 NASA TESS team. Planet TOI-700 d is “100 light-years from Earth in the constellation Dorado”.

A few months ago, a group of NASA exoplanet astronomers, who are in the business of discovering planets around other stars, called me into a secret meeting to tell me about a planet that had captured their interest. Because my expertise lies in modeling the climate of exoplanets, they asked me to figure out whether this new planet was habitable — a place where liquid water might exist.

These NASA colleagues, Josh Schlieder and his students Emily Gilbert, Tom Barclay and Elisa Quintana, had been studying data from TESS (Transiting Exoplanet Survey Satellite) when they discovered what may be TESS' first known Earth-sized planet in a zone where liquid water could exist on the surface of a terrestrial planet. This is very exciting news because this new planet is relatively close to Earth, and it may be possible to observe its atmosphere with either the James Webb Space Telescope or ground-based large telescopes.

Habitable zone planets

The host star of the planet that Gilbert's team discovered is called TESS of Interest number 700, or TOI-700. Compared to the Sun, it is a small, dim star. It is 40% the size, only about 1/50 of the Sun's brightness and is located about 100 light-years from Earth in the constellation Dorado, which is visible from our Southern Hemisphere. For comparison, the nearest star to us, Proxima Centauri, is 4.2 light-years away from Earth. To get a sense of these distances, if you were to travel on the fastest spacecraft (Parker Solar Probe) to reach Proxima Centauri, it would take nearly 20,000 years.

There are three planets around TOI-700: b, c and d. Planet d is Earth-size, within the star's habitable zone and orbits TOI-700 every 37 days. My colleagues wanted me to create a climate model for Planet d using the known properties of the star and planet. Planets b and c are Earth-size and mini-Neptune-size, respectively. However, they orbit much closer to their host star, receiving 5 times and 2.6 times the starlight that our own Earth receives from the Sun. For comparison, Venus, a dry and hellishly hot world with surface temperature of approximately 860 degrees Fahrenheit, receives twice the sunlight of Earth.

Possible climates for planet TOI-700 d

Based on our models, we found that if the atmosphere of planet TOI-700 d contains a combination of methane or carbon dioxide or water vapor, the planet could be habitable. Now our team needs to confirm these hypotheses with the James Webb Space Telescope.
