A multi-color view of MACS0416, a galaxy cluster about 4.3 billion light-years from Earth. The image was created by combining infrared observations from NASA's James Webb Space Telescope with visible light data from NASA's Hubble Space Telescope. The resulting prismatic panorama of the blues and reds gives clues to the distances of the galaxies. Credit: NASA, ESA, CSA, STScI, Jose M. Diego (IFCA), Jordan CJ D'Silva (UWA), Anton M.

The stunning image represents one of the most comprehensive views of the universe ever taken, revealing a rich landscape of galaxies along with more than a dozen variable objects discovered for the first time
The large galaxy at the front of the image is LEDA 2046648, and it looks just over a billion years back in time, while most of the others are even further away, and therefore look further back in time. Credit: ESA/Webb, NASA & CSA, A. Martel

Jupiter (Webb NIRCam image): This image of Jupiter from NASA's James Webb Space Telescope NIRCam (Near Infrared Camera) shows spectacular detail of the planet, which is impressive in infrared light. 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. Milisavljevic (Purdue University), T. Temim (Princeton University), I. De Looze (UGent), J. DePasquale (STScI)

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

One of these galaxies is observed as it appeared about 300 million years after the Big Bang and shines much brighter than expected. This figure now makes researchers estimate that the first galaxies were formed 100 million years after the Big Bang. "It's like an archaeological dig, when you suddenly find a lost city or something you didn't know about," said one of the researchers
