Back in 1990, after significant cost overruns and delays, the Hubble Space Telescope was finally carried into orbit aboard the space shuttle. Astronomers rejoiced, but within a few weeks, elation turned to dread. Hubble wasn't able to achieve anything like the results anticipated, because, ...
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...
This side-by-side comparison shows observations of the Southern Ring Nebula in near-infrared light, at left, and mid-infrared light, at right, from NASA’s Webb Telescope. (NASA/ESA/CSA/STScI) The Southern Ring Nebula, also called the “Eight-Burst,” is 2,000 light-years away from ...
The James Webb Space Telescope (JWST) had been billions of dollars over budget and years behind schedule before it was launched on 25 December 2021. It was a key part of an international mission to launch this huge telescope a million miles from Earth. Scientists said the telescope would be...
For the first time,NASA’s James Webb Space Telescopehas detected and “weighed” a distantgalaxyfrom about 600 million years after theBig Bang. Remarkably, this galaxy appears to have a mass similar to what the Milky Way’s might have been at the same stage of development. Most galaxies ...
Webb’s images reveal a wealth of galaxies glimmering in the distant cosmos, appearing as they did just a few hundred million years after the Big Bang, 13.8 billion years ago. The telescope’s astonishingly sharp pictures have shattered astronomers’ preconceptions about the early Universe....
Astronomers have discovered an early strand of the universe’s cosmic web using the James Webb Space Telescope, existing just 830 million years after the big bang. The study also examined eight quasars in the young universe and revealed significant insights into the assembly and influence of super...
Using the James Webb Space Telescope (JWST), astronomers have discovered star clusters in the "Cosmic Gems" arc that existed just 460 million years after the Big Bang. This marks the first discovery of star clusters in an infant galaxy, seen as it was when the 13.8 billion-year-old univers...
In its first year alone, the telescope has already identified some of themost distant galaxies ever observed, which formed just a few hundred million years after the big bang. Studying these galaxies, which have been beyond the observational reach of other telescopes, can hel...
