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.

The redshift of this galaxy reaches 9.51 meaning that it was seen when the age of the universe was only 550 million years old. The rate of star formation in it is 10 times greater than the Milky Way
NASA's James Webb Space Telescope captured a rich and highly detailed view of the "Pillars of Creation."

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). The images are a mixture of ultraviolet and visible light from Hubble's Wide Field Camera No. 3 and its Advanced Survey Camera. CREDIT: NASA/ESA/LEGUS TEAM

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.
