James Webb Space Telescope

The Webb Space Telescope has provided evidence that contradicts existing theories by confirming the existence of long-lived protoplanetary disks in heavy-element-deficient environments, suggesting the need to change our understanding of planet formation in the early universe.

This image of the Sombrero galaxy, taken by Webb's Medium AA camera, is shown with compass arrows, a scale, and a color key. The image shows wavelengths of medium AA light translated into visible light colors. The color key shows the filters used when they collected the light. The color of each filter name is the color of the visible light used to represent the AA light passing through that filter. The north and east compass arrows show the direction of the image in the sky. Credit: NASA, ESA, CSA, STScI

An international team of astronomers using the NASA/ESA/CSA James Webb Space Telescope has directly imaged an extrasolar planet about 12 light-years from Earth. Although there were hints that the planet existed, it was not confirmed until Webb photographed it. The planet is one of the coldest exoplanets observed so far.

long image captionThis is part of the Evolution of the Universe Early Science Survey (CEERS), consisting of several near-infrared points from the NIRCam (Near Infrared Camera) camera on the James Webb Space Telescope. These observations are being made in the same region studied by the Hubble Space Telescope, known as the Extended Groth Belt. Arrows showing the directions north and east show the direction of the image in the sky. It should be noted that the relationship between north and east in the sky (as seen from below) is reversed compared to the half directions on the map of the earth (as seen from above). The image shows invisible near-infrared wavelengths converted to visible colors. The color key shows which NIRCam filters were used to collect the light. The name color of each filter is the visible color that represents the infrared light passing through that filter. The barrel ruler is marked with arc-seconds which are a measure of angular distance in the sky. One arc-second is equal to an angular measurement of 1/3600 of one degree. There are 60 arc-minutes in a degree and 60 arc-seconds in an arc-minute. (The full moon has an angular diameter of about 30 arc-minutes.) The actual size of an object that covers one arc-second in the sky depends on its distance from the telescope.

The first galaxies were much less developed than the spiral and spherical galaxies that exist today, which are actually the result of mergers, both because of the stage of development but also because of the conditions that prevailed at the time

In this image, brightness indicates a high altitude . The many white "dots" and "marks" are likely very high-altitude cloud edges of condensed convection. The auroras, shown in red in this image, extend to higher altitudes over both the planet's north and south poles. In contrast, dark bands north The equatorial region has no cloud caps.

A star exploding is a dramatic event, but the debris the star leaves behind can be even more dramatic. A new mid-infrared image from the James Webb Space Telescope provides one stunning example. It shows the remains of the supernova Cassiopeia A (Cas A), created by a stellar explosion 340 years ago. The image shows bright colors and complex structures. Cas A is the youngest known remnant of a massive exploding star in our galaxy, offering astronomers an opportunity to understand the star's death process. Image credit: NASA, ESA, CSA, D.

Two of the most distant galaxies ever seen have been revealed in Webb Space Telescope images of the outer regions of the giant galaxy cluster Abell 2744. The galaxies are not inside the cluster, but many billions of light-years behind it. The galaxy shown in the top image in the center was extracted from the image on the left. It existed only 450 million years after the big bang. The galaxy shown in the lower center image is drawn from the image on the right. It existed 350 million years after the big bang. Both galaxies appear to be very close in time to the Big Bang that occurred 13.8 billion years ago. These galaxies are tiny compared to our Milky Way. Webb Space Telescope photo, ESA/NASA
