This NASA Hubble Space Telescope image features a galaxy cluster, called CL0016+1609 or MACS J0018.5+1626, that is very bright at X-ray wavelengths and is one of the most extensively studied clusters at X-ray and radio wavelengths. The X-ray observations of this cluster revealed that it is two clusters merging along our line of sight.

Engineers at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, have completed their final inspection of a key element for the agency’s Nancy Grace Roman Space Telescope: the primary mirror. This 7.9-foot (2.4-meter) mirror will collect and focus light from cosmic objects near and far, helping Roman capture stunning panoramas of space.

Which comes first, the galaxy or the black hole? We don’t know, but scientists have long thought it could be the galaxy: Large stars within an existing galaxy consume their fuel and collapse to form black holes, which can gobble up surrounding material and merge over time to form more massive entities. But it’s hard […]

Look closely at this image from NASA’s Hubble Space Telescope and you’ll see galaxies of various shapes and sizes clustered together toward the center-left of the image. A few foreground stars shine brightly and are easily distinguished by the spikes that appear to extend outward from each star. These spikes, called diffraction spikes, are the […]

A luminous swirl set against the deep black of space, the barred spiral galaxy IC 486 glows with a soft, ethereal light in this new NASA Hubble Space Telescope image. IC 486 lies right on the edge of the constellation Gemini (the Twins), around 380 million light-years from Earth. Classified as a barred spiral galaxy, […]

The Artemis II crew captured this photo of our galaxy, the Milky Way, on April 7, 2026. The Milky Way’s elegant spiral structure is dominated by just two arms wrapping off the ends of a central bar of stars. Spanning more than 100,000 light-years, Earth is located along one of the galaxy’s spiral arms, about […]

The broadest planned survey by NASA’s upcoming Nancy Grace Roman Space Telescope will reveal hundreds of millions of galaxies scattered across the cosmos. After Roman launches as soon as this fall, scientists will use these sparkly beacons to study the universe’s shadowy underpinnings: dark matter and dark energy.
