Morden And Classical
by BOWEN XIE
WINNNER
Description: This work is a star track time lapse photography. Shot in Shenmu, Shaanxi. Shenmu also has classical buildings, there are electric poles, the air is good, the stars are also very clear, so I took this photo. A star orbit is an optical phenomenon, specifically a continuously moving orbit produced by a star in a long exposure image. In other words, the camera does not track the movement of the stars in the night sky; instead, the camera remains stationary, and the stars themselves move over time, resulting in images that show the stars moving in the firmament of the night.

When The Rocket Lifts Off
by ZHAOQIN YANG
2°
Description: First of all, the gas that propels a rocket into space uses internal energy to do work. Second, the fire going down, the rocket going up tells us that the forces are mutual, and then the rocket going higher and higher means that the gravitational potential energy is going up. As the rocket lifts off, there will be a large white air mass at the base of the rocket. Thats because theres a huge pool of water under the rockets launch pad, and when the rockets flames hit the water, the water absorbs heat and vaporizes into steam. Vaporization can absorb a lot of heat, and the temperature of the surrounding environment will be lowered, thus protecting the launch pad. When a large amount of water vapor is liquefied at a lower temperature, it turns into small droplets.

The Nucleation Wonder
by M. Alisherdil
3°
Description: This mesmerising graphic depicts the enchanted realm of bubbles created by the nucleation process in science. The nucleation process manifests itself under a microscope when a liquid, frequently soapy water. Small flaws or foreign materials in the liquid serve as nucleation sites, drawing in gas molecules from the environment. These gas molecules that have been trapped combine, eventually expanding into fascinating bubbles of different colours. Light interference occurs when light waves interact with the thin film of the bubble, causing vibrant hues to appear. You will wonder as you observe the enthralling dance between nucleation and optics that results in a beautiful microcosmic show of rainbow-coloured bubbles.

Magnificent Star Trails
by WENHAO BI
3°
Description: This photo was taken in Kanas, Xinjiang, China, and it captures the trajectories of stars and artificial satellites. Due to the Earths rotation, the stars appear as magnificent star trails in the image. The photo also records the trajectory of the Milky Way - represented by the yellowish band in the middle - as well as the trajectory of an artificial satellite, which is the longest trail in the photo. From this single image, one can both admire the grandeur of the universe and observe the Earths rotation. The settings used for this shot were ISO 100, aperture F4 (with a format of 44mm33mm), and an exposure time of 15 minutes.

Human Interpretation Of The Wavelength Of Light
by ISABELLA VALDEBENITO VALENZUELA
People's Choice Winner
Description: It is an optical phenomenon called "Rayleigh Scattering". During the day, when the Sun is high, sunlight is scattered in all directions as it interacts with molecules in the atmosphere, primarily nitrogen and oxygen. This scattering is most effective for shorter wavelengths like blue and green, which explains why the sky appears blue during the day. However, at sunset, the Sun is closer to the horizon and sunlight has a longer path through the atmosphere to reach our eyes. During this longer path, scattering is more effective and shorter wavelengths are scattered further. This means that blue and green are scattered more and are less visible to us. In contrast, colors with longer wavelengths, such as red, orange, and yellow, have much less dispersion compared to blue and green.

Lunar Occultation Of Venus
by BOCHUN CAO
4°
Description: I took this photo in Sanya, Hainan. When the Moon passes in front of Venus, Venus disappears behind the dark side of the Moon and then reappears on the other side. Rare lunar occultations of Venus, visible to few worldwide. China had only six suitable observations in the last thirty years.

Magic Star
by KAICHUN QIN
5°
Description: The image shows the Seagull Nebula, a giant nebula in the border region between the constellations Monoceros and Canis Major, taken with an astronomical telescope. The Seagull Nebula is quite similar to the Eagle Nebula in the constellation Serpens, so some people call it the Eagle Nebula. In the physical sense, the universe is defined as all space and time and its content, including all forms of energy, among which ordinary matter includes planets, satellites, stars, galaxies, galaxy clusters, and intergalactic matter. The main components of the nebula are gas and dust, that is, hydrogen and helium. The dust and gas are relatively scattered, and gravity pulls the dust and gas together. The clumps are getting bigger and stronger, and the gravity is getting stronger.

Principles Of Interference And Thin-film Interference
by JINGXUAN LV
6°
Description: Principles of interference and thin-film interference: Iridescence in a soap bubble occurs due to interference of light waves reflected from its inner and outer surfaces. Varying thicknesses of the soap film cause constructive and destructive interference, reinforcing certain colors and canceling others. As a result, different wavelengths of light are observed as vibrant colors. The changing thickness of the film and the dynamic nature of the bubble lead to beautiful shifting patterns of colors. In essence, the interplay of interference and thin-film properties creates the mesmerizing and colorful lines seen in a soap bubble under a light source.

Sky’s Painter
by WENXING WANG
7°
Description: When you gaze at the night sky, are you moved by the secrets it holds, or are you conquered by its beautiful spectacle? In the starry sky, we seem so close, yet so distant. Light has a speed limit, as stated in Einsteins theory of relativity; no meaningful matter in the world can exceed this maximum speed. However, due to the expansion of the universe, even the shining stars are beyond our visual reach, creating a natural dark canvas in the sky. Stars generate tremendous energy through nuclear fusion, and this energy is emitted in the form of photons. The color of light is directly related to its energy; when the released energy is too high and the temperature is higher, the wavelength of light becomes shorter, resulting in a blue color.

Cast Iron Blossom
by HAOLUN LIU
8°
Description: The iron is put in the furnace at high temperature and melted, the flower beater picks up a wooden spoon with one hand to carry the iron water at 1600 degrees, and the other hand holds a wooden stick and runs into the open, a fierce blow instantly forms a rain of iron flowers several stories high, golden sparks bloom in the night sky, such as meteors across the sky, suddenly bright as day, the iron water smashes to the ground and splashes pieces of gold flowers. When the temperature rises, the metal atoms will be affected by diffusion and vibration, resulting in the melting of the metal, and the gap between the atoms becomes larger, and the metal will become liquid.

Description: This photo shows the steel wool flinging sparks, the use of camera long exposure and tripod to shoot. One of the steel wool pyrotechnics material for ultra-fine mild steel, low ignition point and flammable, melted into liquid after ignition, the use of "throw" action in contact with a large amount of oxygen in the air, in the process of "dumping" to create a large number of ultra-fine iron, you will see like fireworks fireworks! The same.

An The Rainbow Bubble
by Ruosi Shi
10°
Description: The Rainbow Bubble
This picture of a soap bubble is fascinating because it captures two physical phenomena simultaneously: reflection and interference. The colorful, rainbow-like stripes on the bubble surface are caused by thin film interference. For the soap bubble (considered a thin film), light is partially reflected and partially refracted on the upper surface. Some of the light that passes through is again reflected on the bottom surface. Because the second ray travels some extra distance, it may be in or out of phase with the first light ray, depending on its wavelength. The two light rays interfere with each other, and if they interfere constructively, the intensity of the light ray is strengthened, and we see its corresponding color.

Star Trails Near The Equator
by QIHAN ZHOU
11°
Description: Star trails in the equatorial region differ from those in other areas due to Earths rotation. The equatorial region is located near Earths equator, and its rotation axis is parallel to the equator. Consequently, when photographing star trails at the equator, stars appear to revolve around Earths axis in a straight line or arc.

The Milky Way Of The Gobi Spring
by RUIYAO QIN
13°
Description: The Milky Way is made up of dense clusters of stars. This "belt" region is the densest because of the vast lenticular system of more than 100 billion stars that houses the solar system. From the solar system, humans can see the outer parts of the disk as a belt. This area of the sky has the densest stellar projection, and this is the Milky Way as seen. This massive system of stars is also named the Milky Way, after the Milky Way. The Milky Way can only be seen with the naked eye if the limit apparent magnitude is above 5.5 or the light pollution index level is below 5. This photo was taken at the Gobi Spring in Guazhou, Gansu Province. After completing the Gobi coming-of-age ceremony that night, I photographed the beautiful Milky Way under the night sky.

Saturn Conjunct Moon
by WENJING LI
14°
Description: When Saturn and the moon have the same apparent right ascension when viewed from the center of the Earth, it is called a conjunction of Saturn and the moon. Usually during a lunar month, when Saturn is relatively close to the moon. At the time of the lunar eclipse, the phenomenon of Saturn merging with the Moons right ascension and reaching mid heaven occurs in the same geographic longitude area on Earth. When Saturn and the moon meet at a very small angle, the phenomenon of lunar eclipse of Saturn may occur in some parts of the Earth. During this period, Saturn will wear a straw hat shaped halo and display its "star pose" at close range to the moon, allowing the naked eye to see the astronomical interest of "Saturn merging with the moon".
