NASA's Hubble Images Show Binary Stars Can Shape the Evolution of Star Clusters
Astronomers studying the young star cluster Pismis 24 in the Lobster Nebula found many stars exist in binary systems

Hubble Reveals How Blue Straggler Stars Stay Young in Ancient Clusters
Astronomers using the Hubble Space Telescope have uncovered new clues to the mystery of blue straggler stars—unusually hot, bright stars found in ancient globular clusters. By studying ultraviolet light from 48 clusters, scientists discovered that blue stragglers are more common in sparse clusters, supporting the idea that they form through binar...

NASA Hubble Space Telescope Uncovers One of the Youngest Known Blue Straggler–White Dwarf Systems
Italian astronomers using the Hubble Space Telescope have discovered a white dwarf orbiting a blue straggler star in the globular cluster 47 Tucanae, located 15,300 light-years away. The rare system, among the youngest detected, sheds light on stellar mass transfer and offers vital clues to the evolution of binary stars in dense clusters.

Hubble Observations Give Forgotten Globular Cluster Its Moment to Shine
NASA’s Hubble Space Telescope has unveiled ESO 591-12, a long-overlooked globular cluster glittering with multicolored stars. Captured during a survey of missing clusters, this image provides new insight into stellar evolution and the early Milky Way. It marks a vital step in resolving the structure and origin of ancient star systems hidden withi...

Hubble Telescope Captures NGC 4536, a Starburst Galaxy with Intense Star Formation
NASA’s Hubble Space Telescope has captured a striking image of NGC 4536, a starburst galaxy 50 million light-years away in the Virgo constellation. The galaxy’s sweeping spiral arms are filled with young blue star clusters and ionized hydrogen gas, indicating rapid star formation. Astronomers believe its bar-like structure channels gas toward t...

Webb Telescope Tracks Formation and Expansion of Carbon-Rich Dust Shells in Star System
As per the latest report by NASA, the system consists of two stars in an elongated orbit. When these stars come closest, their stellar winds collide, compressing material and forming carbon-rich dust. As reported in an official press release by NASA, Emma Lieb, a doctoral student at the University of Denver and the study's lead author, noted that t...

NASA’s Hubble Observes Rare Blue Lurker Star with Unusual Evolution in M67 Cluster
NASA’s Hubble Space Telescope has identified a rare stellar phenomenon called the “blue lurker” in the M67 star cluster. Located 2,800 light-years away, this star is part of a triple-star system and has an unusual evolutionary history. The blue lurker’s accelerated spin, taking just four days, contrasts with the typical rotation of Sun-like...

Astronomers Unlock Clues to Star Birth in Neighbouring Galaxy
After analysing images of 2,753 young, blue star clusters in the neighbouring Andromeda galaxy (M31), astronomers with the help from "citizen scientists" have found that M31 and our own Milky Way have a similar percentage of new-born stars based on mass.
