This year, the James Webb Space Telescope celebrated its first full year of operation, during which it returned a treasure trove of images. And it’s just getting started.
Since it first began sending pictures back home in July 2022 from its location 1.5 million kilometers beyond Earth’s orbit, JWST has peered deeper in space and farther back in time than any previous telescope could manage (SN: 7/11/22). Hundreds of scientific papers have already been published based on JWST
When the Hubble Space Telescope launched, we soon learned its images were blurry. Engineers had to build the equivalent of eyeglasses for it. Were there any such problems with J.W.S.T. early on, given its very complicated deployment?
Because of the way it worked, when Hubble went up in space, the optics had to be perfect. For J.W.S.T., we launched mirrors that were able to fix themselves. There are eighteen primary mirror segments—those beautiful gold hexagons—and the idea is that you
Since launching on Christmas Day 2021, NASA’s $10 billion (£7.4 billion) James Webb Space Telescope (JWST) has beamed back astonishing images of the cosmos with unprecedented detail.
Webb was launched with the aim of looking back in time to the dawn of the universe so it can capture what happened a couple of hundred million years after the Big Bang.
It will spend more than a decade at an area of balanced gravity between the sun and Earth called L2

Mehrere markante Oberflächenmerkmale sind gekennzeichnet: Kraken Mare gilt als Methanmeer; Belet besteht
Die NASA wollte sich die Gelegenheit nicht entgehen lassen Erobere seinen historischen Hinterhalt eines Asteroiden durch die Augen seiner mächtigsten Weltraumobservatorien. Am Donnerstag veröffentlichten die NASA und die Europäische Weltraumorganisation neue Bilder, die von den Teleskopen Hubble und James Webb aufgenommen wurden und den Moment zeigen Die Raumsonde DART stürzte in den Asteroiden Dimorphos.
DART wurde als erstes Experiment der Menschheit zur kinetischen Aufprallminderung entwickelt, was viele Silben bedeutet, dass das Ziel darin bestand, ein Raumschiff in einen Asteroiden
Space enthusiasts across the world were starstruck by the first set of full-colour photos taken by NASA’s James Webb Space Telescope (JWST) released yesterday.
But what they may not have spotted hidden among the 60-page commissioning report are two brand new photos of Jupiter.
The glowing snaps of the gas giant – the closest one to Earth in our Solar System – were taken by the telescope when it was being tested.
They show Jupiter’s rings as well as three
President Joe Biden shared the first image from NASA’s James Webb Telescope tonight – the deepest and sharpest infrared look at the distant universe to date – revealing a picture of a cluster of galaxies 4 billion light-years away from Earth.
‘These images are going to remind the world that America can do big things and remind our children that there’s nothing beyond our capacity,’ Biden said.
‘We can see things no one has seen before and go places no
The first target of the NASA James Webb Space Telescope is a sun-like star in the Great Bear constellation, but it is just to check the mirrors are properly aligned.
The $10 billion telescope is months from being ready to begin operations, despite arriving at its final orbit on January 24, as it has to cool down and undergo weeks of calibration work, to ensure the 18 segments of the main mirror ‘work as one’.
After reaching its orbit, at
Thousands of astronomers are sitting anxiously waiting for the launch of a space telescope that could dictate the next decade of their careers.
The James Webb Space Telescope (JWST) is NASA’s successor to Hubble, but it goes much further than the iconic observatory, able to view more than Hubble could.
When a $10 billion piece of equipment launches, it brings with it thousands of research proposals, observation time and researchers hoping to uncover the secrets of our universe, and answer
In the beginning, the universe was dark. The Big Bang had electrified the cosmos into existence, and the new landscape buzzed with particles, chaotic and hot, before cooling off into a calm expanse of hydrogen and helium. Then something began to happen in the fog. Gravity drove pockets of gas to collapse in on themselves and ignite, creating the first stars. The radiant orbs began to cluster, forming the first galaxies: messy, misshapen things, not as polished as
