Webb/JWST Science

You might recall the SMACS deepfield image from the first set of images released by JWST, where it showcased gravitational lensing in stunning detail. Recently, a new deep-field image has been released, accompanied by a scientific paper. Let's take a fast overview of this new image and paper to po

Fast Facts Webb used the NIRCam instrument to study globular cluster NGC 6440 orbits within the bulge of the galaxy 28,000 light years away. Globular clusters include thousands to millions of older stars tightly bound together by gravity. Main Sequence Bi-modality: Webb discovered a split in the m

The Data Astronomers used Cepheid variable stars to measure distances across the Universe. These observations were used to calculate the Hubble constant, the rate of the universe's expansion. This study presents a significant discrepancy between the expansion rate calculated from Cepheids and th

Hot stars fade, and cooler gas and dust glow. Points of light indicate embedded protostars that are still gaining mass within these stellar nursery clouds. Unlike shorter wavelengths of light that are absorbed or scattered by dust grains in the nebula, longer mid-infrared wavelengths penetrate t

Straight to the point Enceladus, a wee moon of Saturn, has been detected as emitting an immense plume of water vapour by NASA's James Webb Space Telescope. Water expelled from Enceladus may be significantly impacting the surrounding environment and reaching other celestial bodies within Saturn's s

Straight to the point The mighty James Webb Space Telescope has peered into the atmosphere of a scorching exoplanet called WASP-39 b. There was a lot of organic stuff detected by Webb, as you can see from the data. The Data Scientists used multiple powerful instruments on Webb to analyze starli

Throwback to July 11, 2022, when we first marveled at the infrared data provided by the technological marvel, the James Webb Space Telescope. The spectra data from Webb revealed the chemical composition of galaxies in the very early universe. This incredible achievement was made possible by th

The Science This graphic presentation compares the spectral data of the kilonova GRB 230307A as observed by the James Webb Space Telescope with a kilonova model. Both display a distinct peak in the spectrum region associated with tellurium, highlighted in red. The detection of tellurium, which is

Did you know that we can now measure the composition of galaxies over 13 billion light-years away? This incredible feat is thanks to the James Webb Space Telescope. The Data • In this Webb science data, we'll explore this graph, which analyses a distant galaxy in the SMACS 0723 galaxy cluster. Th
