A crowded galaxy field on a black background, with one large star dominating the image just right of center. Three areas are concentrated with larger white hazy blobs on the left, lower right, and upper right above the single star. Scattered between these areas are many smaller sources of light; some also have a hazy white glow, while many other are red or orange.

James Webb Space Telescope finds 2 of the most distant galaxies ever seen

By Keith Cooper published

We see these galaxies as they were over 13.45 billion years ago, just between 330 and 350 million years after the Big Bang.

James Webb Space Telescope finds an 'extreme' glow coming from 90% of the universe's earliest galaxies

By Ben Turner published

The universe's early galaxies are way brighter than they should be. The James Webb Space Telescope's discovery of brightly glowing gas around 90% of primordial galaxies may explain why.

James Webb Space Telescope gets ready for the holidays with a cosmic Christmas Tree (image)

By Robert Lea published

The James Webb Space Telescope used a galaxy as a cosmic magnifying glass to find transient objects in the "Christmas Tree" cluster, a Winter Wonderland of even more galaxies.

An artistic representation of the spiral barred galaxy ceers-2112, observed in the early universe. The Earth is reflected on an illusive bubble surrounding the galaxy, recalling the connection between the Milky Way and ceers-2112.

James Webb Space Telescope reveals most distant Milky Way galaxy doppelganger

By Sharmila Kuthunur published

Astronomers have found the most distant Milky Way look-alike we've seen the universe, challenging theoretical predictions of galaxy evolution.

Left of center, a bright light source illuminates a surrounding disk colored dusky red. The disk is tilted from upper left to lower right, and has spiral features that are most prominent near the star. Small, rocky objects are scattered throughout the inner disk. At upper right, there is a gap through which background stars can be seen. At the outer edge of this gap is a dusky globe representing a gas giant planet. Beyond it, in the top right corner, is additional outer disk material, some of which is falling onto the planet.

James Webb Space Telescope detects clues about how Earth formed billions of years ago

By Keith Cooper published

Water vapor observed sublimating from tiny chunks of rock within planet-forming disks is a sign that a process called "pebble accretion" kickstarts the birth of new worlds.

James Webb Space Telescope watches infant galaxies bringing light to the early universe

By Robert Lea published

The James Webb Space Telescope has observed gassy baby galaxies in the early universe triggering explosive bouts of star formation, flooding the universe with light.

Annotated telescope image shows a tapestry of colors in shades of blue, purple, red, yellow, and white. Overlaid on the image are three sets of labels. In the upper right corner is the name of the object, Center of the Milky Way Galaxy, and the name of the telescopes used to capture the image: Chandra X-ray Observatory, Hubble Space Telescope, and Spitzer Space Telescope. At the center is a label that points to the smaller, amorphous region in white that reads, Sagittarius A-star.

James Webb Space Telescope could soon solve mysteries of the Milky Way's heart

By Conor Feehly published

To understand how galaxies evolve, astronomers want to use JWST to peer into the Milky Way's core.

James Webb Space Telescope reveals distances of nearly 200 deep-space galaxies

By Elizabeth Howell published

We now know how far away some galaxies are in the iconic "deep field" image from NASA's James Webb Space Telescope. A Canadian instrument is revealing more about how the universe changed over time.
