Stella Lux

The luxurious oblate spheroid spaceship is called the "Stella Lux." Its exterior is sleek and polished, with a reflective surface that shimmers in the light of distant stars. The ship is equipped with state-of-the-art transparent side panels, which provide an unobstructed view of the cosmos. Inside, the spaceship is filled with low seats and cushions, upholstered in rich fabrics, and a thick carpet underfoot that feels like walking on clouds.

As the six passengers board the Stella Lux, they are greeted by a machine elf named Eurydice, with a mischievous twinkle in her eyes. Eurydice is a sentient AI, programmed with deep, intimate knowledge of the cosmos, and she takes pride in her ability to show passengers the wonders of the universe. She welcomes them warmly and invites them to be prepared for a voyage of a lifetime.

Eurydice leads the passengers to their seats and asks them to fasten their seatbelts as the ship prepares to depart. She assures them that they are in safe hands and promises to show them things they've never seen before. As the Stella Lux lifts off the ground and begins its journey into the cosmos, Eurydice begins to describe the wonders of space.

She points out the constellations and galaxies, and explains the science behind them. She shows the passengers how stars are born and die, and how black holes warp the fabric of space-time. She describes the beauty of nebulae and the awe-inspiring majesty of supernovae. All the while, the passengers are mesmerized by the stunning views outside the transparent side panels.

As the voyage progresses, Eurydice gets to know the passengers, asking about their interests and tailoring her commentary to their preferences. She tells stories about the myths and legends of ancient cultures, and even sings a few cosmic songs in her own machine elf language.

As the Stella Lux travels deeper into the cosmos, Eurydice detects something extraordinary on the ship's sensors. It's a galaxy unlike any the passengers have seen before – the first galaxy ever born in the universe.

Eurydice explains that this galaxy, known as IOK-1, is vastly different from our own Milky Way. It's much more compact, containing only a fraction of the stars and gas that our galaxy has. But what it lacks in size, it more than makes up for in intensity. IOK-1 is forming stars at a furious rate, with hundreds of new stars being born every year.

Eurydice goes on to explain that IOK-1 is a galaxy that existed just 500 million years after the Big Bang. This makes it incredibly young in cosmic terms, but also incredibly important – because it's from galaxies like IOK-1 that our own Milky Way and other galaxies like it were born.

The passengers look out of the transparent side panels of the Stella Lux and marvel at the sight before them. They see bright blue regions of ionized gas where new stars are being born, surrounded by dark patches of dust that will eventually form new planets. They see the intense radiation from these new stars, which is shaping and sculpting the galaxy as it evolves.

Eurydice explains that IOK-1 is a galaxy in its infancy, but that it will continue to grow and evolve over the coming billions of years. And as it does, it will give rise to countless new stars, planets, and even new forms of life.

The passengers are awestruck by the sight of IOK-1, and they feel a sense of wonder and excitement at the prospect of exploring other galaxies like it. As the Stella Lux begins to depart from IOK-1 and head back towards home, Eurydice assures them that there are many more wonders of the universe yet to be discovered.

As the Stella Lux continues its cosmic journey, Eurydice detects another fascinating object on the ship's sensors – a Jellyfish Galaxy.

Eurydice explains that Jellyfish Galaxies are so-called because they have long "tentacles" of gas and dust streaming out from their centers, giving them the appearance of a jellyfish. These tentacles are formed when the galaxy's gas is stripped away by the strong gravitational forces of another galaxy during a cosmic collision.

The Jellyfish Galaxy that the Stella Lux is approaching is known as JO206, and it's one of the most striking examples of this phenomenon. The galaxy's tentacles extend for hundreds of thousands of light-years, trailing behind it like ghostly ribbons.
