Webb Telescope Finds Water Vapor – But Is It From a Rocky Planet Or Its Star?

The seven galaxies highlighted in this James Webb Space Telescope image have been confirmed to be at a distance that astronomers refer to as redshift 7.9, which correlates to 650 million years after the big bang. This makes them the earliest galaxies yet to be spectroscopically confirmed as part of a developing cluster. Credits: NASA, ESA, CSA, T. Morishita (IPAC). Image processing: A. Pagan (STScI)

Composite image of dwarf galaxy Markarian 71, 11 million light years from Earth. Optical and infrared observations of Mrk71 resolve a question about two methods used to measure the composition of galaxies and could lead to improved studies with infrared space telescopes. (Hubble Space Telescope)

Making Better Measurements Of The Composition Of Galaxies

This image of the Hubble Ultra Deep Field was taken by the Near-Infrared Camera on NASA’s James Webb Space Telescope. The Webb image observes the field at depths comparable to Hubble – revealing galaxies of similar faintness – in just one-tenth as much observing time. It includes 1.8-micron light shown in blue, 2.1-micron light shown in green, 4.3-micron light shown in yellow, 4.6-micron light shown in orange, and 4.8-micron light shown in red (filters F182M, F210M, F430M, F460M, and F480M).

This illustration shows the swirling clouds identified by the James Webb Space Telescope in the atmosphere of exoplanet VHS 1256 b. The planet is about 40 light-years away and orbits two stars. The planet’s clouds, which are filled with silicate dust, are constantly rising, mixing, and moving. Credit: NASA, ESA, CSA, Joseph Olmsted (STScI)
