A small image of a galaxy that has been distorted into a faint ring by gravitational lensing. At the top of the ring are three very bright spots with diffraction spikes coming off them, right next to each other: these are copies of a single quasar in the borrowed galaxy, duplicated by the gravitational lens. … Read more
Researchers investigated three mysterious objects in the early universe. Shown here are their color images, compiled from three NIRCam filter bands aboard the James Webb Space Telescope. They are remarkably compact at red wavelengths (earning them the name “little red dots”), with some evidence of spatial structure at blue wavelengths.

The James Webb Space Telescope (JWST) has provided a breathtaking glimpse into the early stages of star formation, capturing the dramatic development of a protostar in a luminous hourglass-shaped cloud. This observation, which illuminates the complex processes involved in star birth, provides profound insights into the behavior and evolution of young stellar objects. Observation of … Read more
One of the surprising discoveries of the Webb telescope is an early population of compact red galaxies at redshifts above 7, a time when the universe was 20 times younger than it is today. The galaxies are redder than expected based on their cosmological redshift, suggesting additional reddening by a layer of dust. Some of … Read more
L1527 and Protostar (MIRI image). Credit: Space Telescope Science Institute The cosmos seems to come to life with a crackling explosion of pyrotechnics in this new image from NASA’s James Webb Space Telescope. Taken with Webb’s MIRI (Mid-Infrared Instrument), this fiery hourglass marks the scene of a very young object in the process of becoming … Read more
This image is a mosaic of visible light and infrared views of the same frame from the Pillars of Creation visualization. The three-dimensional model of the pillars created for the visualization sequence is displayed alternately in the Hubble Space Telescope version (visible light) and the Webb Space Telescope version (infrared light).

9 Using the joint NASA, European Space Agency (ESA) and Canadian Space Agency (CSA) James Webb Space Telescope, a group of scientists have discovered a variety of never-before-seen features in Jupiter’s upper atmosphere. The features were found in the atmospheric region above the iconic Great Red Spot, a high-pressure area in Jupiter’s atmosphere that creates … Read more
This infrared image from NASA’s James Webb Space Telescope was taken by the Near-Infrared Camera for the JWST Advanced Deep Extragalactic Survey program – Credit: NASA, ESA, CSA, STScI, Brant Robertson (UC Santa Cruz), Ben Johnson (CfA), Sandro Tacchella (Cambridge), Phill Cargile (CfA) For two years, an international team has been studying what astronomers call … Read more
Using the James Webb Space Telescope (JWST), astronomers have discovered previously unseen structures and activity in Jupiter’s atmosphere above the Great Red Spot. These strange features appear to be caused by powerful atmospheric gravitational waves. The Great Red Spot is the largest storm in the solar system, twice the size of Earth, and has been … Read more
The gleaming towers of cosmic dust and gas at the heart of the Eagle Nebula have inspired awe for decades since they were first captured by the Hubble Telescope. Now NASA issued the most detailed visualization of the iconic celestial structure, revealing all its dreamlike features across multiple wavelengths of light. Webb telescope visualizes the … Read more
