根据第一段中的"The James Webb Space Telescope (JWST)had been billions of dollars over budget ... before it was launched on December 25th, 2021.”可知,詹姆斯 · 韦伯太空望远镜在2021年发射之 前已经超出预算几十亿美元。 故选A 6.C [细节理解题。 根据第三段中的“ This ability to look back...
The James Webb Space Telescope (JWST), expected to launch in 2021, will be the next premier observatory for astronomers worldwide. It is optimized for infrared wavelengths and observation 1.5 million kilometers from Earth. JWST includes an Integrated Science Instrument Module (ISIM) that contains ...
That light can't be seen by the iconic Hubble, which Webb will eventually replace. Hubble was designed to study visible light wavelengths but even so, it has detected galaxies dating back to within a half billion years of the Big Bang. ...
The James Webb Space Telescope (JWST) has potentially smashed one of its own records again, potentially spotting the earliest and most distant galaxies ever seen. The five candidate galaxies are so distant that the powerful space telescope sees them as they were just 200 million years after the...
As one of the first objects captured by the powerful James Webb Space Telescope in the summer of 2022, this simple splotch represents the dawn of a new age for astronomy because of how utterly ancient it appears to be. And now, scientists have officially confirmed precisely how old the uni...
The James Webb Space Telescope (JWST) is a revolutionary orbiting observatory that will peer deeper into the universe than ever before. With its unparalleled capabilities, the telescope will reveal the secrets of our cosmos, including the first galaxies that formed after the Big Bang, and t...
Let’s start with the big stuff. The Webb has peered back about as far as is possible and found something that…..shouldn’t exist. According to existing cosmological theories, the universe is about ??13.787 billion years old. This is determined by the cosmic microwave background radiation ...
James Webb Telescope Discovers Distant Globular Clusters A team of astronomers used the James Webb Telescope (JWST) to identify the most distantglobular clustersever discovered. These dense groups of millions of stars may be relics containing the first and oldest stars in the universe. ...
The images were created from a composite of several images from Webb and show auroras extending to high altitudes above both the northern and southern poles of Jupiter. The Great Red Spot, a storm so big it could swallow Earth, appears white in these views, as do other c...
The Webb telescope will look at every phase of cosmic history, including the first glows after the big bang that created our universe and the formation of the galaxies, stars and planets that fill it today. Its capabilities will enable the observatory to answer questions about our own solar sy...
