Mapping Dark Matter – This image shows two massive galaxy clusters. The vast number of galaxies and foreground stars in the image were captured by NASA’s James Webb Space Telescope in near-infrared light. Glowing, hot X-rays captured by NASA’s Chandra X-ray Observatory appear in pink. The blue represents the dark matter, which was precisely mapped by researchers with Webb’s detailed imaging.

An Eye-catching Star Cluster

Westerlund 1 is the biggest and closest “super” star cluster to Earth. Data from Chandra and other telescopes are helping astronomers delve deeper into this galactic factory where stars are vigorously being produced. Observations from Chandra have uncovered thousands of individual stars pumping out X-ray emission into the cluster.

Picture of the day





A close-in image of a protoplanetary disc HH 30 around a newly formed star produced by NASA/ESA/CSA James Webb Space Telescope. It is surrounded by jets and a disc wind, and is located in the dark cloud LDN 1551 in the Taurus Molecular Cloud. Herbig-Haro objects are small nebulae found in star formation regions, marking the locations where gas outflowing from young stars is heated into luminescence by shockwaves. HH 30 is an example of where this outflowing gas takes the form of a narrow jet. The source star is located on one end of the jet, hidden behind an edge-on protoplanetary disc that the star is illuminating.

25th Anniversary Cupola Photo

The 25th anniversary logo is visible in the cupola of the space station in this July 17, 2025, image. The central astronaut figure is representative of all those who have lived and worked aboard the station during the 25 years of continuous human presence. In the dark sky of space surrounding the astronaut are 15 stars, which symbolize the 15 partner nations that support the orbiting laboratory.

Stellar Duo

The bright variable star V 372 Orionis takes center stage in this image from the NASA/ESA Hubble Space Telescope, which has also captured a smaller companion star in the upper left of this image. Both stars lie in the Orion Nebula, a colossal region of star formation roughly 1450 light years from Earth.

Far Out

The star cluster Pismis 24 lies within the much larger emission nebula called NGC 6357, located about 8,000 light-years from Earth. The gas below the stars glows through ionization caused by intense ultraviolet radiation from the massive young stars within the cluster.

Webb Sees Sombrero Galaxy in Near-Infrared

NASA’s James Webb Space Telescope recently imaged the Sombrero Galaxy with its NIRCam (Near-Infrared Camera), which shows dust from the galaxy’s outer ring blocking stellar light from stars within the galaxy. In the central region of the galaxy, the roughly 2,000 globular clusters, or collections of hundreds of thousands of old stars held together by gravity, glow in the near-infrared. The Sombrero Galaxy is around 30 million light-years from Earth in the constellation Virgo. From Earth, we see this galaxy nearly “edge-on,” or from the side.

Sculpted by Luminous Stars

This new image showcases the dazzling young star cluster NGC 346. Although both the James Webb Space Telescope and the Hubble Space Telescope have released images of NGC 346 previously, this image includes new data and is the first to combine Hubble observations made at infrared, optical, and ultraviolet wavelengths into an intricately detailed view of this vibrant star-forming factory.

Like Sands Through the Hourglass…

Shimmering ejections emitted by two actively forming stars make up Lynds 483 (L483). High-resolution near-infrared light captured by NASA’s James Webb Space Telescope shows incredible new detail and structure within these lobes, including asymmetrical lines that appear to run into one another. L483 is 650 light-years away in the constellation Serpens.
