A spiral galaxy, seen up close and face-on. It is colored yellow and glowing brightly at the oval-shaped center, showing older and cooler stars, and it becomes bluer out to the edge of the disc where the stars are younger and hotter. It has a number of somewhat patchy spiral arms curling around, with sparkling areas where stars form. The black background is visible in the corners.

At center right is a compact star cluster composed of luminous red, blue, and white points of light. Faint jets with clumpy, diffuse material extend in various directions from the bright cluster. Above and to the right is a smaller cluster of stars. Translucent red wisps of material stretch across the scene, though there are patches and a noticeable gap in the top left corner that reveal the black background of space. Background galaxies are scattered across this swath of space, appearing as small blue-white and orange-white dots or fuzzy, thin disks. There are two noticeably larger points, foreground stars, with diffraction spikes: an orange-white point on the left, and a blue-white point in the top right.

NASA’s Webb Peers into the Extreme Outer Galaxy

Astronomers have directed NASA’s James Webb Space Telescope to examine the outskirts of our Milky Way galaxy. Scientists call this region the Extreme Outer Galaxy due to its location more than 58,000 light-years away from the Galactic Center. (For comparison,…

This is an artist's depiction of a pair of active black holes at the heart of two merging galaxies. They are both surrounded by an accretion disk of hot gas. Some of the material is ejected along the spin axis of each black hole. Confined by powerful magnetic fields, the jets blaze across space at nearly the speed of light as devastating beams of energy.

An image of a celestial scene showing two bright stars against a dark background, with one star appearing larger and more luminous on the right, and a smaller, dimmer star to the left. A planet is silhouetted as it transits in front of the larger star. The background is filled with a soft glow and scattered faint stars.

Amid a field of galaxies, a repeated, elongated red galaxy forms a shape like the top of a question mark, with another galaxy positioned like the question mark’s dot. In each occurrence, another white, clumpy galaxy with an overall circular shape appears perched on top of the red galaxy. A very bright foreground galaxy appears to the right of the bottom curve of the question mark shape. To the lower right, among other galaxies, another occurrence of the galaxy pair appears, unaffiliated with the question mark shape.
