Spying a spiral through a cosmic lens
Expand your imagination 🍥 What appears to be a single galaxy is actually two that are very far apart! The closer galaxy lies in the center of the image, while the more distant galaxy appears to be wrapped around it in a phenomenon we call an “Einstein ring.” Einstein rings occur when light from a distant galaxy gets bent by the gravity of a massive closer-by object, in this case another galaxy. The light from the distant galaxy that would otherwise travel in a straight line follows the bend of gravitationally warped spacetime, brightening the light from behind the galaxy and acting as a sort of natural magnifying glass. Einstein predicted this effect in his theory of relativity. https://esawebb.org/images/potm2503a/ [https://esawebb.org/images/potm2503a/]
JWST finds ‘smoking gun’ evidence of early galaxies transforming the universe
Using the James Webb Space Telescope (JWST), an international team of astronomers has found compelling evidence that early galaxies were responsible for the reionization of the early universe. This is the process by which neutral hydrogen atoms are ionized, making the universe transparent to light at wavelengths that would have been absorbed by the atoms. The research was done by members of the EIGER collaboration, which is using the JWST’s Near Infrared Camera (NIRCam) to study light from quasars in the early universe. https://physicsworld.com/a/jwst-finds-smoking-gun-evidence-of-early-galaxies-transforming-the-universe/ [https://physicsworld.com/a/jwst-finds-smoking-gun-evidence-of-early-galaxies-transforming-the-universe/]
The peculiar galaxy NGC 3256 dominates this image from the James Webb Space Telescope. This Milky Way-sized galaxy lies about 120 million light-years away in the constellation Vela, and is a denizen of the Hydra-Centaurus Supercluster. https://www.flickr.com/photos/nasawebbtelescope/53019007937/in/album-72177720305127361/ [https://www.flickr.com/photos/nasawebbtelescope/53019007937/in/album-72177720305127361/]
Webb Celebrates First Year of Science With Close-up on Birth of Sun-like Stars
Cheers to our first year! Let’s celebrate one year of Webb science by taking a brand-new look at Sun-like stars being born in this detailed close-up of Rho Ophiuchi, the closest-star-forming region to Earth. Webb spotted around 50 young stars, many close in mass to our star, giving us a glimpse into the early life of the Sun. Dark, dense dust cocoons still-forming protostars, while an emerging stellar newborn (top center) shoots out two huge jets of molecular hydrogen. https://www.flickr.com/photos/nasawebbtelescope/53040527259/in/album-72177720305127361/ [https://www.flickr.com/photos/nasawebbtelescope/53040527259/in/album-72177720305127361/]
NASA’s Webb Catches Fiery Hourglass as New Star Forms
Hidden in the neck of this “hourglass” of light are the very beginnings of a new star — a protostar. The clouds of dust and gas within this region are only visible in infrared light, the wavelengths that Webb specializes in. https://www.flickr.com/photos/nasawebbtelescope/52504158265/in/album-72177720301006030/ [https://www.flickr.com/photos/nasawebbtelescope/52504158265/in/album-72177720301006030/]
Webb Captures the Spectacular Galactic Merger Arp 220
A stunning smash-up of two spiral galaxies shines in infrared with the light of more than a trillion suns. Collectively called Arp 220, the colliding galaxies ignited a tremendous burst of star birth. Each of the combining galactic cores is encircled by a rotating, star-forming ring blasting out the glaring light that Webb captured in infrared. This brilliant light creates a prominent, spiked, starburst feature.

Webb found complex organic molecules similar to smoke or smog in a galaxy more than 12 billion light-years from Earth. https://www.flickr.com/photos/nasawebbtelescope/52958010034/in/album-72177720305127361/ [https://www.flickr.com/photos/nasawebbtelescope/52958010034/in/album-72177720305127361/]
