Did you know? At the edge of the solar system lies a vast "mysterious garden" composed of trillions of icy celestial bodies, resembling an endless ocean of stardust This garden is called the Qost Cloud, the most distant boundary of the solar system and the "cradle" of long-period comets. However, its true form has long remained a mystery — until recently, when NASA's supercomputer unveiled a surprising revelation: the Qort Cloud may possess a peculiar spiral structure, much like the arms of the Milky Way, filled with cosmic poetry and mystery.

The Qort Cloud is the "invisible guardian" of the solar system, shrouding our home like a delicate veil, lying at an immense distance from the Sun. To put it into perspective, if you set out from the Sun, light would take 1.6 years to reach the inner edge of the Qort Cloud and over 1.5 years to reach its outer boundary! This distance makes the Qort Cloud a "transition zone" between the solar system and interstellar space, serving as a "bridge" that connects us to the vast cosmos. Traditionally, the Oert Cloud is considered spherical, like a uniform "shell" encasing the solar system. However, groundbreaking supercomputer simulations have revealed a startling fact: the Qort Cloud may exhibit a spiral structure, akin to the arms of the Milky Way, brimming with dynamic beauty. The formation of this spiral pattern is primarily attributed to the gravitational field of the Milky Way. Galactic gravity is not uniform- it pulls on the bodies within the Oort Cloud like cosmic tides. Over time, these gravitational forces have gradually arranged the icy bodies into a spiral distribution, offering us an entirely new perspective on the evolution of the solar system.

In a way, the Qort Cloud resembles a massive "carousel," with the gravity of the Milky Way acting as an "invisible hand" that sets it in motion. On this celestial carousel, trillions of icy bodies twinkle like scattered lanterns, slowly aligning into a spiral pattern over time. This dynamic elegance makes the Qort Cloud a true "artistic masterpiece" of the cosmos. The formation of the Qort Cloud traces back to the

"childhood" of the solar system. Around 4.6 billion years ago, the Sun and its planetary system emerged from a vast cloud of gas and dust. The icy bodies within the Oort Cloud are primarily composed of water ice, methane ice, ammonia ice, and dust particles remnants of the early solar system. By studying these objects, we can glimpse into the "childhood memories" of the solar system and understand how it evolved from a chaotic cloud of gas into the structured system we see today.

The Kuiper Belt and the Qort Cloud are like the "twin guardians" of the solar system —while the Kuiper Belt is more like the solar system's "backyard," the Qort Cloud serves as its "frontier." Imagine a future where a spacecraft ventures beyond the Kuiper Belt and crosses into the boundaries of the Qort Cloud. Like a fearless explorer, it would traverse the "frontier" of the solar system, bringing back firsthand data about this enigmatic garden. These discoveries would deepen our understanding of the formation and evolution of the solar system and might even unlock further cosmic mysteries.

The Qort Cloud is the most distant boundary of the solar system and one of the most enigmatic regions of the cosmos. Its spiral structure not only reveals the dynamic beauty of the universe but also provides a fresh perspective on solar system evolution.

Although we have yet to directly observe it, with advancing technology. Perhaps one day, we will finally unveil the secrets of this "mysterious garden." 

The mysteries of the universe are boundless, and the Qort Cloud is merely one small part of the grand cosmic puzzle. If you are fascinated by the wonders of the cosmos, stay tuned for discoveries from scientific teams as they continue to unravel the

unknown.
