Towards the end of the year, looking back at 2023, humans have sent "envoys" to celestial bodies such as Jupiter, the Moon, and asteroids to further reveal their "true face of Mount Lu"; The James Webb Space Telescope has captured unprecedented high-definition images of the universe, showcasing its vastness and splendor to people; Some of the mysteries of the universe, including gamma ray bursts, have also been revealed under the relentless pursuit of scientists. Since the James Webb Space Telescope began sending back photos, many of its images have amazed the world, showcasing the colorful colors of the universe. This year, the Webb Space Telescope captured new images of amazing circular nebulae. The image shows that the entire nebula is surrounded by a layer of oxygen, which causes the nebula to emit green light when the light emitted by the star passes by. The annular nebula is approximately 2600 light-years away from Earth and is located in the direction of the constellation Lyra. It is a product of dust and gas ejected from the outer layer of a dying star. This image reveals the final chapter of a star's life and can also be seen as a preview of the future fate of the sun, helping to further understand the future of the solar system. Saturn is clearly the most photographed planet in the solar system. On June 30th this year, NASA released a photo of Saturn taken by the near-infrared camera of the Webb Space Telescope, revealing its fine structure that cannot be seen at other wavelengths. A young star in the Perseid molecular cloud has released a stunning interstellar rapids, forming the Herbig Haro 211 celestial body. Similar to the newborn baby sun that has only been born for tens of thousands of years, Webb's high-resolution near-infrared observation and related spectral analysis of Herbig Haro 211 allow people to glimpse the evolution of the solar system. Sending more "envoys" to the universe In 2023, scientists have sent many "envoys" to the universe. In April of this year, the European Space Agency launched the Jupiter Ice Moon Explorer (JUICE) towards Jupiter. According to the plan, JUICE will undergo 8 years of space travel and arrive in the Jupiter system by 2031. At that time, it will explore Jupiter and its three ice satellites (Europa, Ganymede, and Callisto), study Jupiter's atmosphere and magnetic field, the ice crust on the surface of the ice satellites, and the composition of compounds, and explore the possibility of life on the ice satellites. The moon can be described as a super internet celebrity in the field of space exploration. In August of this year, India's Luna 3 spacecraft landed at the South Pole of the Moon, making it the first spacecraft to land near the South Pole of the Moon. The lander and rover ran for a lunar day (equivalent to two weeks on Earth), and then died in the severe cold of the lunar night. The data it collects on the moon has not yet been analyzed and released, but the goal of the mission is to find water sources near Antarctica, which may be crucial for manned missions and even the construction of permanent lunar bases in the coming decades.
