The image shows the barred spiral galaxy NGC 1559 as seen by the James B. Space Telescope. The galaxy contains a clear central region with a distinctive open pattern in the loose spiral arms. NGC 1559 is about 35 million light-years away in the little-observed southern constellation, the Reticulum. Credit: ESA/Webb, NASA & CSA, A. Leroy, J. Lee and the PHANGS team.

An artist's impression of the large-scale landscape of FU~Ori. The image shows the currents created by the interaction between strong stellar winds triggered by the outburst and the remnant mantle from which the star formed. The stellar wind drives the shock wave into the mantle and the CO gas carried away by the shock is the new discovery of the ALMA observatory. Credit: NSF/NRAO/SDagnello

Image: Horsehead Nebula (NASA Webb NIRCam): This image of the Horsehead Nebula, taken by NASA's James Webb Space Telescope, focuses on a portion of the "Horse's Mane" that is about 0.8 light-years across. It was taken using a camera Webb's NIRCam (near-infrared camera) The airy clouds at the bottom of the image are dominated by cold molecular hydrogen. Red streaks extending above the main nebula represent mostly atomic hydrogen gas in this region, known as the photodissociation region and from nearby masses creates a mostly neutral region of gas and dust between the fully ionized gas above and the cooler nebula below. As in many Webb images, distant galaxies are scattered in the background. This image consists of light at wavelengths of 1.4 and 2.5 microns (shown in blue), 3.0 and -3.23 µm (cyan), 3.35 µm (green), 4.3 µm (yellow), and 4.7 and 4.05 µm (red). Credit: NASA, ESA, CSA, K.

The galaxy AM 1054-325 has been warped from a normal pancake-like spiral shape into an S shape by the gravitational pull of a neighboring galaxy, as seen in this Hubble Space Telescope image. As a result, new star clusters were formed along a tidal tail stretched over thousands of light years, resembling a string of pearls.

These six images represent the variety of star-forming regions in nearby galaxies. The galaxies are part of the Hubble Space Telescope's Legacy ExtraGalactic UV Survey (LEGUS). This is the largest and most comprehensive survey of ultraviolet (UV) light observations of star-forming galaxies in the near Universe. the neighbor The six images include two dwarf galaxies (UGC 5340 and UGCA 281) and four large spiral galaxies (NGC 3368, NGC 3627, NGC 6744 and NGC 4258).

An animation showing how the orbits of stars in the Milky Way may change. In the picture you see two pairs of stars (marked in blue and red). Each couple started their life on the same path and suddenly one of the stars in the couple changed its path. The star marked in red has completed its transition to its new orbit while the star marked in blue is still moving.
