1/ 🆕 Webb reaches new milestone 📍 in the quest for distant galaxies, having discovered some that date back to less than 400 million years after the #BigBang 🎇 The light from these galaxies has taken more than 13.4 billion years to reach us. 
2/ “It was crucial to prove that these galaxies do, indeed, inhabit the early universe. It’s very possible for closer galaxies to masquerade as very distant galaxies,” said astronomer and co-author Emma Curtis-Lake from @UniofHerts UK
@UniofHerts 3/ The observed region in this image is 15 times larger than the deepest infrared images produced by @HUBBLE_space yet is even deeper and sharper at these wavelengths.
1/ This new Webb picture of the month shows IC 1623, a pair of interacting galaxies, plunging into one another. Their collision has ignited a spate of star formation creating new stars at a rate above 20 times that of the Milky Way. Read more 👉 esawebb.org/images/potm221… and 👇
2/ Astronomers used Webb's #MIRI, #NIRSpec, and #NIRCam instruments to investigate IC 1623. This will allow scientists to unravel the interactions in galactic ecosystems. These observations are also accompanied by data from other observatories, like @HUBBLE_space #BFFinSpace
@HUBBLE_space 3/ The luminous core of this merger is very bright and highly compact, so much so that Webb’s diffraction spikes appear atop the galaxy in this image. The 8-pronged diffraction spikes are created by the interaction of starlight with the physical structure of the telescope.
📢 #Webb reveals never-before-seen details of galaxy group “Stephan’s Quintet”, giving astronomers a ringside seat to galactic mergers and interactions. Read more here: esawebb.org/news/weic2208/ or below 👇
Stephan’s Quintet is a visual grouping of 5 galaxies with only 4 of the galaxies truly close together & caught up in a cosmic dance — a fantastic “laboratory” for scientists to see in detail how interacting galaxies trigger star formation & how gas is being disturbed 👇
Tight groups like this may have been more common in the early universe when their infalling material may have fuelled very energetic black holes. Even today, the topmost galaxy harbours an active galactic nucleus, a supermassive black hole 24 million times the mass of the Sun 👇
📢 #Webb delivers deepest image of the Universe yet, looking far back in time when the Universe was less than a billion years old. The image is about the size of a grain of sand held at arm’s length, yet it reveals thousands of galaxies. Read more esawebb.org/news/weic2209/ or 👇
This is Webb’s First Deep Field, the deepest, sharpest infrared image of the distant Universe so far. It shows galaxy cluster SMACS 0723 as it appeared 4.6 billion years ago, with many more galaxies in front of and behind the cluster 👇
The combined mass of this galaxy cluster acts as a gravitational lens 🔎 magnifying more distant galaxies, including some seen when the Universe was less than a billion years old 👇
1/ #NIRSpec has three modes of operation: multi-object spectroscopy mode, fixed slits spectroscopy mode and integral field spectroscopy mode:
2/ 🔴 multi-object spectroscopy mode — #NIRSpec will be the 1st multi-object spectrograph in space, able to record the spectra of up to 200 objects at the same time. A capability enabled by microshutters.
3/ 🔴 fixed slits spectroscopy mode — #NIRSpec will also be able to carry out single-object, high-contrast spectroscopy using a set of five fixed slits. It will provide high contrast spectra of sources and a key to the study of exoplanets.
Tutto pronto per seguire il lancio del telescopio spaziale #Webb alle 13:20 ora italiana #Jwst
