How do rogue planetary-mass objects -- celestial bodies with masses between stars and planets -- form? An international team of astronomers has used advanced simulations to show that these enigmatic ...

"We were surprised by the streams of light that were visible near the center of the galaxies, as nothing similar has been observed in the past." When you purchase through links on our site, we may ...

Ursa Major III, previously classified as a dwarf spheroidal galaxy due to its high mass, is proposed to be a compact star cluster located 32,600 light-years from the Milky Way. The research team ...

For the first time, astronomers using NASA’s Fermi Gamma-ray Space Telescope have traced a budding outflow of gas from a cluster of young stars in our galaxy — insights that help us understand how the ...

Using the Hubble Space Telescope, astronomers have made the first direct observation of star clusters colliding and merging at the hearts of dwarf galaxies. The discovery could help scientists settle ...

The final ESA/Webb Picture of the Month feature for 2025 showcases a festive-looking region filled with glowing clouds of gas and thousands of sparkling stars. This star cluster, known as Westerlund 2 ...

The constellation Taurus is readily identifiable in the Northern Hemisphere's fall and winter skies, characterized by its prominent V-shaped Hyades cluster and the bright, reddish 1st-magnitude star ...

Spring means it’s time to look up into our night sky and find one of the oldest objects in our galaxy: the M3 Cluster. NASA and other sky experts call this group of ancient stars “a truly distant ...

Star clusters are of great importance in any galaxy: they are the birthplace of new stars, often containing massive stars of 10 solar masses or more. Such massive stars often drive powerful winds; the ...

A new 527-megapixel image captures two open star clusters, NGC 456 and NGC 460, orbiting our Milky Way galaxy. The image uses two different telescopes, the Hubble Space Telescope and the James Webb ...

A new simulation could help solve one of astronomy’s longstanding mysteries—how supermassive black holes formed so rapidly—along with a new one: What are the James Webb Space Telescope’s (JWST) ...
