After delayed 14 years and more than 20 times the budget, the Weber telescope consumed by more than $ 10 billion was successfully launched, and 5 precious photos were passed back to half a year later.

On July 12, the National Aeronautics and Space Agency (NASA) announced a series of full -color deep space images and its spectrum data of James Weber Space Telescope. This is by far that we can observe so far The deepest and clearest infrared image of the distant universe.

"James Webb Telescope is the most extensive wantpaper generator in the world." "

Weber telescope is the most expensive wallpaper generator in the world.

Between the stars and the stars, between the clockwise, the nebula is all showing

From ancient times to the present, human beings have been questioning the truth of the universe. Chinese poet Qu Yuan more than 2000 years ago in "Skywi":

"At the beginning of the ancient times, who preached?

Why is it not formed up and down? "

Song Dynasty poet Su Shi once sighed in "Red Cliff Fu":

"Sending it in the heavens and the earth, one of the sea of ​​Miao Cang.

The sorrow of my life is the endlessness of the Yangtze River. "

Compared with the bright stars, the rushing Yangtze River is not worth mentioning, not to mention that we can only look at the shining mortals of the stars?

Just last month, the "Wannian Pigeon King" James Weber Space Telescope (JWST) sent the first full color postcard. At the Lagram L2 point about 1.5 million kilometers away from the earth, the micro -creature crafts in the depths of the space of human beings was looking back at the beginning of the universe, the first group of stars.

This is a photo of 4.6 billion light years from Earth, SMACS 0723 galaxy group located in the south of Feiyu Constellation. In this photo, there are thousands of galaxies. And its size is equivalent to putting a grain of your fingertips in a free arm, which can cover the sky.

Among them, some galaxies even came from 13 billion years ago. According to scientists, the birth of the universe is only about 13.7 billion years. In other words, the nebula we see is the "baby universe" at the beginning of the Big Bang. This is the first time that we have such a clear look at the early universe. JWST surpasses the ability of Hubble Space Telescope, which can directly observe part of the space and time that humans have never seen before, and will stare at the era of the first star and galaxy 13.5 billion years ago.

The successful launch of the James Weber Space Telescope indicates that humans have obtained an innovative perspective of observing the mysterious universe. Dr. Susan Mullally of the Institute of Space Telescope Science participated in the project, and she talked to Frontiers about this rare opportunity. Mullally has also served as Deputy Director of The WHOLE Earth Telescope, responsible for coordinating the one -month -old star -variable observation activity of Tellawa University, and serving as a scientist at Cairple Space Task at the Armos Research Center and Seti Institute of Astronomical Agreement. Looking for Lingri foreign planets. She is currently working with Frontiers as deputy editor -in -chief of Frontiers in Astronomy and Space Sciences (IF: 4.055), which is responsible for the content of the external planet field.
