The James Webb Space Telescope (JWST) is the most complex and sophisticated observatory ever deployed. Using its advanced suite of infrared instruments, coronographs, and spectrometers – contributed by NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA) – this observatory will spend the next ten to twenty years building on the achievements of its predecessor, the venerable Hubble. This includes exoplanet characterization, star and planet formation, and the formation and evolution of the earliest galaxies in the Universe.
However, one of the main objectives of the JWST is to study the planets, moons, asteroids, comets, and other celestial bodies here in the Solar System. This includes Mars, the first Solar planet to get the James Webb treatment! The images Webb took (recently released by the ESA) provide a unique perspective on Mars, showing what the planet looks like in infrared wavelengths. The data yielded by these images could provide new insight into Mars’ atmosphere and environment, complimenting decades of observations by orbiters, landers, rovers, and other telescopes.
Here’s the Tarantula Nebula like we’ve never seen it before. The James Webb Space Telescope turned its detectors towards the Large Magellanic Cloud about 161,000 lightyears away to take a look at 30 Doradus, more commonly known as the Tarantula Nebula. JWST’s exceptional infrared view has now revealed thousands of never-before-seen young stars in this stellar nursery, as well incredible views of the wispy, dusty filaments and the impressive collection of massive older stars.
There is so much detail in this image, if you download the full-sized version, you can pan and zoom around to see details on stars and the surrounding dust and gas. And there are even other, more distant galaxies dotting the background. If you have a big screen, even better, as it takes up over 14,000 x 8,000 pixels. Or, take a look at the video tour, below.
An early – and exciting — science result from the James Webb Space Telescope (JWST) was announced today: the first unambiguous detection of carbon dioxide in the atmosphere of an exoplanet. This is the first detailed evidence for carbon dioxide ever detected in a planet outside our Solar System.
A team of scientists using the James Webb Space Telescope have just released the largest image taken by the telescope so far. The image is a mosaic of 690 individual frames taken with the telescope’s Near Infrared Camera (NIRCam) and it covers an area of sky about eight times as large as JWST’s First Deep Field Image released on July 12. And it is absolutely FULL of stunning early galaxies, many never seen before. Additionally, the team may have photographed one of the most distant galaxies yet observed.
In a recent study submitted to MNRAS, a collaborative research team has utilized the first set of data from the James Webb Space Telescope (JWST) discovering a galaxy candidate, CEERS-93316, that formed approximately 250 million years after the Bing Bang, which also set a new redshift record of z = 16.7. This finding is extremely intriguing as it demonstrates the power of JWST, which only started sending back its first set of data a few weeks ago. CEERS stands for Cosmic Evolution Early Release Science Survey, and was specifically created for imaging with JWST.
Over the years, members of the public have regularly made exciting discoveries and meaningful contributions to the scientific process through citizen science projects. These citizen scientists sometimes mine large datasets for cosmic treasures, uncovering unknown objects such as Hanny’s Voorwerp, or other times bring an unusual phenomenon to scientists’ attention, such as the discovery of the new aurora-like spectacle called STEVE. Whatever the project, the advent of citizen science projects has changed the nature of scientific engagement between the public and the scientific community.
Now, unusual brown dwarf stars discovered by citizen scientists will be observed by the James Webb Space Telescope, with the hopes of learning more about these rare objects. Excitingly, one of the citizen scientists has been named as a co-investigator on a winning Webb proposal.
The James Webb Space Telescope (JWST) continues to both dazzle and amaze with its latest image, this time of Galaxy IC 5332, also known as PGC 71775, which is an intermediate spiral galaxy located approximately 30 million light years away. This comes after JWST released its first images at its full power, which includes the Carina Nebula, Stephan’s Quintet, Southern Ring Nebula, and SMACS 0723, the last of which was the deepest and sharpest image of the distant universe to date.
The JWST is grabbing headlines and eyeballs as its mission gains momentum. The telescope recently imaged M74 (NGC 628) with its Mid-Infrared Instrument (MIRI.) Judy Schmidt, a well-known amateur astronomy image processor, has worked on the image to bring out more detail.
After the ‘big reveal’ earlier this week of the James Webb Space Telescope’s first full color images and spectra of the universe, the science team has now released data from closer to home. One stunning shot includes Jupiter and its moons, and there are also data from several asteroids. These latest data are actually just engineering images, designed to test JWST’s ability to track solar system targets, as well as test out how the team can produce images from the data. The quality and detail in these test images have excited the mission scientists.
A ‘throwaway’ engineering image from the James Webb Space Telescope’s commissioning phase has turned out to be a stunningly deep view of the cosmos. It rivals the deepest of Hubble Deep Field images in revealing previously unseen distant galaxies.
