Red, white, and blue stars glitter like a sparkler being waved on a dark night in this new image from NASA’s Hubble Space Telescope.
More than 500,000 stars blaze red, white, and blue in this NASA Hubble image of the globular cluster Messier 3 (M3).
The subject of today’s NASA/ESA Hubble Space Telescope image is an ancient inhabitant of our galaxy. This sparkling scene features a globular cluster: a collection of tens of thousands to millions of stars, all tightly bound together under the influence of gravity. There are more than 150 globular clusters in our galaxy, though there may be […]
Researchers using two of humanity’s most powerful observatories — NASA’s James Webb and Hubble Space Telescopes — have definitively shown that Terzan 5 is not a globular star cluster as it was once classified, offering new insight into how galaxies like our own form and evolve over time. A globular star cluster typically has only […]
This image of Westerlund 2 released on March 19, 2026, features Chandra X-ray Observatory data (pink) and infrared data from NASA’S James Webb Space Telescope (red, orange, green, cyan, and blue). Scores of gleaming stars ringed in neon pink stretch across the frame, highlighting a cluster where stars are between one and three million years […]
This near-infrared image released on May 6, 2026, shows a section of one of the spiral arms of Messier 51 (M51). M51 is one of four nearby galaxies observed by NASA’s James Webb Space Telescope in a study of nearly 9,000 star clusters. Data from the study shows that more massive star clusters emerge more […]
Scientists have found that young stellar cousins of our Sun are calming down and dimming more quickly in their X-ray output than previously thought, according to a new study using NASA’s Chandra X-ray Observatory. A paper describing the results published Monday in The Astrophysical Journal. Unlike in the new movie “Project Hail Mary,” this quieting […]
Data from Chandra adds red, green, and blue twinkling lights in this Dec. 22, 2025, image of Pismis 24 from NASA’s James Webb Space Telescope. Pismis 24 is a young cluster of stars in the core of the nearby Lobster Nebula, approximately 5,500 light-years from Earth in the constellation Scorpius. Home to a vibrant stellar nursery […]
