James Webb Space Telescope

This galaxy experienced a tumultuous and fast life: the star formation process worked quickly and suddenly ended, a situation that is not expected at such an early stage in the evolution of the universe. It is still unclear whether the "frozen" state of the galaxy is temporary or permanent, and what is the reason for the cessation of the star formation process
Webb's measurements provide new light on a decade-long mystery known as the Hubble voltage - the differences in the age of the universe between the Hubble observations and past observations that remain unexplained * Prof. Adam Ries, winner of the Nobel Prize in Physics for the discovery of dark energy heads the project
The Webb telescope has observed what appear to be young methane deposits on the surface of Eris and Maki Maki
These are relatively close galaxies that face the Earth. The research reveals new details about the way galaxies are formed
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
Beta Pictoris is a solar system in the making and relatively close so that the gas disks can be seen. It turns out that Webb was able to discover a structure that was not noticed in photographs with less sensitive instruments, thus he discovered a disk of gas tilted from our main disk and because of our vantage point it looks like a cat's tail
The James Webb Space Telescope discovered a previously unseen jet stream in Jupiter's atmosphere. Similar phenomena have been observed in Saturn, and both may be related to temperature variations in the atmospheres of the gas giants
Herbig-harrows are luminous regions surrounding young stars. They form when stellar winds or jets of gas ejected from these stars create shock waves that collide at high speeds with nearby gas and dust.
The Ring Nebula, formed by a star shedding its outer layers, is a classic example of a planetary nebula and is also relatively close to us.
This is the first time that such an emission of water has been seen from such a great distance, and in addition, the web allows researchers a direct view, for the first time, of how this emission feeds the water supply of the entire system of Saturn and its rings
The galaxy is currently 25 billion light-years away, but when light began to travel from it to us about 12.5 billion years ago, it was much closer, because the universe is expanding
The first findings from the James Webb space telescope hinted at galaxies so early and massive that they are somewhat inconsistent with our understanding of the formation of structure in the universe. A new study tries to deal with these contradictions
The belts surround the hot young star, which can be seen with the unaided eye as the brightest star in the southern group Southern Pisces. The dust belts are fragments from the collisions of larger bodies, corresponding to asteroids and comets, and are often described as "fragment disks"
Webb recorded what remained after the death of a star only 11 thousand light years away from us. It is a relatively new supernova - only 350 years old
The Webb Space Telescope photographed in detail 11 of the rings surrounding Uranus-Uron
Previous infrared studies of the NGC 346 nebula have focused on stellar embryos heavier than five to eight times the mass of our Sun. With the help of the Web, it is possible to reach even lighter protostars, as small as a tenth of our sun
However, the conditions there are more reminiscent of Venus than Earth. It orbits a red dwarf in an orbit that lasts only two days * Webb was able to confirm the existence of the planet after only two orbits
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
NASA's James Webb Space Telescope captured a rich and highly detailed view of the "Pillars of Creation." A region where new stars form within dense clouds of gas and dust that was previously captured in an iconic image by the Hubble Space Telescope at the start of its operation and returned to after upgrades, along with Strong landmasses
Webb's instruments reveal new details about star formation
The light spectrum - which contains information about the composition of a planetary atmosphere 1,150 light years away - reveals a clear signature of water * The strength of the signal that Webb detected hints at the significant role that the telescope will play in the search for potentially habitable planets in the coming years
The proximity of four of the five Stefan galaxies to each other (the fifth only seems close) allows astronomers to ignite galactic mergers and intergalactic reactions. And also how black holes affect the flow of matter between galaxies
