I made a joke in my main Discord server about DOOM E1M1 being in a major key and @abigbagofkeys.sickonedude.com actually made it. Jesus fucking Christ listen to this hahahaha

At first glance the density map looks very familiar (galactic core to the right). So perhaps not a lot new but I will take a look.

Giant planets orbiting red dwarfs are uncommon, as are hot Neptunes ("Neptunian desert"), as are exoplanets in polar orbits. On this painting, the host star "observes" its strange planet through a massive polar dark spot.

Theia: The Plot Device

Theia is commonly depicted as a generic airless planet with lava pools on its cratered surface...essentially the popular, outdated depiction of how Earth was when it was young. Here's my take on this hypothetical planet.

#astronomy #space #art #SolarSystem #planet #Theia
The image depicts the hypothetical planet Theia, which was invoked to have collided with Earth to form the Moon when the Solar System was young. The planet is depicted as a temperate world with volcanic islands and even huge magma plume uplifts under the thick, hazy atmosphere. Also in the image is a fictional depiction of the collisional history of the inner planets; the top of this diagram shows the surviving planets: Mercury, Venus, a fictional planet, Earth, Theia, Mars, and another fictional planet. The two fictional planets would later be ejected.

History of Venus

Young Venus probably received too much sunlight for water to ever condense on its surface; instead the water stayed in the atmosphere, gradually lost, until Venus desiccated and became the dry, hot world we know today.

#astronomy #space #art #SolarSystem #planet #Venus
The picture depicts the history of Venus as I understand it. The planet initially started out with a magma ocean, not unlike Earth. When this magma ocean cooled, water began to be outgassed. Unlike Earth however, this water failed to condense out of the atmosphere; instead it remained in the air, making the atmosphere water-rich. Atmospheric water vapour absorbs red light, causing the planet to turn blue, and suppresses cloud formation on dayside. Over time, water was lost, one way or another. This eventually dried Venus up, resulting in the planet we know of today: one with carbon dioxide and nitrogen rich atmosphere maintaining a hot, dry surface, and shrouded by clouds of water and sulfuric acid. The image features a brief "poem" which writes "Where rain ever fell, Tell tales never told, Bold unchanging lands".

Siderian Terra: The Breakthrough

Perhaps one of the most important moments in the history of Terra, one over a billion years in the making.

The image depicts Earth during the Siderian Period, during the event known as Great Oxidation Event. Oxygen produced by cyanobacteria finally began to accumulate in the planet's atmosphere during this time, and the planet enters a glaciation event. Although widely believed to be one, there is little evidence of a global glaciation ("snowball Earth") during this time; evidence suggests something more comparable to the modern day Quaternary glaciation. The atmospheric oxygen reacted with iron dissolved in the ocean, producing swathes of rusty red seas. The oxidized iron sank to the ocean floor, producing banded iron formation.

Hadean Terra: Earth when it was young.

Very little rock remained to tell the story of what the Hadean Eon was like; what we know is mostly based on theories and meteorites.

#astronomy #space #art #SolarSystem #planet #Earth #gijinka
The Hadean Eon is the first eon in the history of Earth, spanning from around 4.5 to 4.0 billion years ago. This image depicts my current understanding of its evolution during the early stages of the Hadean Eon. Towards the beginning of this eon, a Mars-sized protoplanet known as Theia impacted the proto-Earth, producing Earth and the Moon. This event likely melted the planet and creating a magma ocean. During the magma ocean stage, Earth probably had a thick, Venus-like atmosphere of carbon dioxide, carbon monoxide, and nitrogen, and clouds of silicate and salt may have formed. The atmosphere is probably thick enough to scatter the majority of sunlight back to space, producing its pale appearance. The magma ocean took a few million years to solidify. Once this stage ended, water may have begun outgassing, and eventually rained down, forming a global ocean of liquid water. The hot ocean stage featured a liquid water ocean under a thick carbon dioxide-nitrogen atmosphere not unlike Venus's, which enabled water to stay as liquid under surface temperature of 500 Kelvin. Higher up in the atmosphere, a layer of water clouds covered the entire planet, not unlike what is today seen on Venus. Interactions with liquid water gradually transformed carbon dioxide into carbonates, removing it from the atmosphere. After between 10 to 100 million years, most carbon dioxide had been removed. With much of the carbon dioxide removed, the planet's surface temperature would have dropped to temperate levels, and glaciation is also possible. The Earth's crust and mantle were likely weak during this time, and such it may be that very little landmasses, if any, existed during this early time. Terra (personification character) noted that due to the planet's geological activities, very little evidence remained from this eon. Much of what we understand about this time comes from theoretical modelings and comparison with other bodies in the Solar System.

I spent almost 2 hours painstakingly copying the orbits of all 128 Saturnian moons from the announcement MPEC and reformatting them for visualization...

Behold, here are the orbits of ALL 128 MOONS OF SATURN. This isn't just a moon system—it's a literal asteroid belt around Saturn! 🧪🔭☄️
Saturn's outer moon system viewed from the north pole of Saturn. Moons orbiting in clockwise (retrograde) orbits have red-colored orbits while moons orbiting counterclockwise (prograde; in the direction of Saturn's spin) are colored blue. With so many irregular moons occupying the same region and intersecting each other, the irregular moon system looks like a donut-shaped vortex surrounding Saturn. Each of the 128 new moons is highlighted in the diagram with a white point representing their location, and a brighter-colored orbit. Previously-known moons of Saturn are included in the diagram, but are colored darker. The regular moons of Saturn are colored turquoise and the outermost regular moons (Titan, Hyperion, and Iapetus) labeled with their name. At the lower left corner are scale indicators to help visualize the scale of Saturn's irregular moon system. A small gray circle at the left left corner is shown to represent the diameter of the Earth-Moon orbital distance. A linear scale bar is labeled "10 million km" (6.2 million mi) to give a standard distance. View of Saturn's irregular moon system, tilted at an angle to show the toroidal belt-like shape of the system. Each moon is labeled with their names in turquioise. Red orbits = retrograde direction, and blue orbits = prograde direction. Turquoise curves closer to the center are orbits of Saturn's regular moons. Side view of Saturn's irregular moon system, tilted at an angle to show the toroidal belt-like shape of the system. Red orbits = retrograde direction, and blue orbits = prograde direction. Turquoise curves closer to the center are orbits of Saturn's regular moons. The irregular moons of Neptune (dark green) are also visible in the background to the right of Saturn. The horizontal red line protruding right of Saturn is the orbit path of Saturn.
