Reseachers detect a new ultra-metal-poor star

Astronomers report the discovery of a new ultra-metal-poor star as part of the Southern Photometric Local Universe Survey (S-PLUS). The newly found star, designated SPLUS J210428.01−004934.2, turns out to have the lowest ...

New ultra metal-poor star discovered

An international team of astronomers has detected a new ultra metal-poor star with the lowest ever measured abundance of iron. Designated SMSS J160540.18−144323.1, the newly found object is the most iron-deficient star ...

Artificial intelligence finds the first stars were not alone

By using machine learning and state-of-the-art supernova nucleosynthesis, a team of researchers have found the majority of observed second-generation stars in the universe were enriched by multiple supernovae. Their findings ...

A rare star opens a window on the beginning of time

EPFL astrophysicists actively participated in the discovery of a very rare star, which is particularly old and metal-poor. As a messenger from the distant past, it will allow the scientists to learn more about the young universe, ...

Beyond the brim, Sombrero Galaxy's halo suggests turbulent past

Surprising new data from NASA's Hubble Space Telescope suggests the smooth, settled "brim" of the Sombrero galaxy's disk may be concealing a turbulent past. Hubble's sharpness and sensitivity resolves tens of thousands of ...

Metal-poor stars are more life-friendly, suggests study

Stars that contain comparatively large amounts of heavy elements provide less favorable conditions for the emergence of complex life than metal-poor stars, as scientists from the Max Planck Institutes for Solar System Research ...
