Description: Aurora is a large-scale discharge process around the earth. As part of the solar wind, charged particles rush to the earth at a speed of 3 million kmh. When they reach near the earth, they are captured by the earths magnetic field, causing some of them to approach the north and south poles along the field line. When these charged particles enter the polar upper atmosphere, they collide with atoms and molecules in the atmosphere, which will produce 1 million trillion energy. Small particles in the earths atmosphere will release energy; for instance, oxygen atoms emit green or red light, oxygen molecules emit red or yellow light, and nitrogen molecules emit purple or pink light.

Description: If you stand by a lake and look down at the water beneath your feet, you will see that the water is transparent and not particularly reflective; If you look at the lake in the distance, you will see that the water is not transparent, but the reflection is very strong. This is called the Fresnel effect. This photo was taken in Xia pu tidal-flat area in Fujian Province, China. In the evening, after the low tide, fishermen are fishing for shellfish in the shallow water. The sunset shines on the water, reflecting the light and shadow, creating a unique scene of abundance.

Description: In the morning scene shown in the photograph, the spiders web above a succulent plant is decorated with dewdrops like a veil of crystal, making the flowers even more delicate. Dewdrop formation is a liquefaction phenomenon. In the warm season, the air is relatively humid, and when the temperature drops gradually, the water vapor in the air cools and liquefies into small droplets that fall on plants and form transparent dewdrops which shine incredibly bright due to total internal reflection. At the same time, the nano-scale natural hydrophobic layer on the plant surface allows the landscape to be preserved.

Description: The butterfly uses camouflage or crypsis as a defense method, especially in these seasons of the year where its colors become more opaque and serve to hide, we can also appreciate in this type of butterfly its points that are like eyes that serve to confuse to the attackers.

Description: This picture shows the star trails under the radio telescope. The star trails are the path of light produced by a star moving across the sky using a long exposure. The distance variation and azimuth variation of stars relative to the solar system can be ignored.The earths rotation axis points to the position of Polaris, so it looks like all the stars will rotate from east to west around Polaris. The position of the stars does not move with respect to the stellar background. The image was taken between 12 and 1 a.m. at the Miyun Radio Astronomy Observatory.

Description: In this photo you can see the band of our home galaxy, the Milky Way, stretching across the night sky. Visible at the bottom of the band is a brighter and larger region of the Galaxy, called the Bulge, which is the star-dense central region of the Milky Way, home to the Galactic Center. This is actually a supermassive black hole around which the stars orbit before falling into it and disappearing forever. However, this black hole is not directly visible because it is obscured by the many dust clouds of the Milky Way. These dust clouds can be seen in the photo as dark spots on their band. These dust clouds are also the birthplace of new stars. Thus, it can be said that every part of our Milky Way hides secrets and is interesting.

Description: When numerous species are poised to feed on them, it is difficult for a butterfly to live its life to the fullest. Butterflies wing patterns have developed to frighten off predators by resembling their eyes, which also helps in camouflaging. Butterflies have long tongues called proboscis that can curl and uncurl for drinking nectar.

Description: Hydrogen atoms of the chromosphere (hot gas layer above the photosphere of the Sun) emit a specific red light which corresponds to the H-α spectral line. I assembled a 9 panels mosaic of the Sun using a dedicated refractor that shows different structures such as prominences, filaments or sunspots.

Description: The sunlight is refracted in atmosphere and that’s why the Sun is still visible after it’s geometrically below the horizon. Hence, a red shape is still visible in the clouds at the photo, even tough, the Sun was apparently below the horizon. Moreover, pink, orange colours are present because the blue light is scattered and only longer- wavelength hits the clouds.

Description: Lets be the change we want to see in the world. . . Small acts can and do make a big difference. It is time to make changes, improve and correct errors, pollinators are in decline, ⅓ of food, biodiversity and habitat balance depend on them. Bees are more than just honey, their most important task is pollination, they are a lineage with more than 20,000 known species, and the biodiversity of forests depends on all of them. Each one is irreplaceable, they play an essential role because without their help nothing will be the same. Among them there are already some that are in extinction, so it is vitally important to take care of them and protect them. The basis of this protection is the regeneration of habitats and the decontamination of chemicals. Remember that your house is also ours.
Description: I met this scene when I was travelling in Yunnan. It is called solar halo. It is an atmospheric optical phenomenon which appears when the sunshine through the volume layer cloud and reflects or refracts by the ice crystals. When the sunshine rip into the ice crystals in clouds, it will become different color lights go to different direction with the twice refraction. It usually comes in spring or summer. It is also a sigh which means wind and rain is coming soon. In some countries, there will be more than one hundred and thirty days with the solar halo in a year. When I first saw this scene, I just thought it was like an eye of the sky.

Description: Wood fungi are plants that lack chlorophyll. That is why they cannot produce their food, and it is the carbohydrates contained in the wood that they feed on. In addition, the average temperature and existing humidity favor the growth of wood fungi.

Description: Damselflies can be commonly seen mating in the rainy season in the bushes. This picture covers the same thing.

Description: Because of the rotation of the Earth, circumpolar constellations can be seen in several directions overnight and throughout the year. I standed for an opportunity to see the Great Bear running on the horizon, pursued by the Herdsman. I also found a secret passageway ; if you light it with your red headlamp, it should lead you to these giants in the sky!

Description: This picture shows the solidarity of snails. Some garden snails prefer to eat from the same food source as another snail, even if there is another food right next to it. Family dinner?... Who doesnt love?...The shell of the recently discovered species Angustopila dominicae is less than .1 mm (about 0.8 mm) and as such is probably the smallest land snail ever found. If you line up 10 of these creatures in a row, they can all go through a pinhole together. Snails shorter than 5 mm are called microgastropods.
