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 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 […]

Astronomers have revolutionized our understanding of a collection of stars in the northern sky called the Pleiades. They used data from NASA’s TESS (Transiting Exoplanet Survey Satellite) and other observatories as NASA explores the secrets of the universe for the benefit of all, from the Moon to Mars and beyond.

This NASA/ESA Hubble Space Telescope image released on Sept. 12, 2025, features a cloudy starscape from an impressive star cluster. This scene is in the Large Magellanic Cloud, a dwarf galaxy situated about 160,000 light-years away in the constellations Dorado and Mensa. With a mass equal to 10–20% of the mass of the Milky Way, the Large […]
