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.

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.
