Using the Ankara University Kreiken Observatory (AUKR) in Turkey, astronomers have performed high-resolution spectroscopic observations of a metal-poor star known as HD 1936. Results of the observations campaign, published ...
Astronomers have discovered a new stellar system in the outskirts of the Milky Way as part of the Kilo-Degree Survey (KiDS). The newfound system, named Sextans II, is most likely an ultra-faint dwarf galaxy. The finding is ...
An international team of astronomers reports the detection of a new extremely metal-poor star using the Gemini High-resolution Optical SpecTrograph (GHOST) at the Gemini South telescope in Chile. The finding was presented ...
The first stars illuminated the universe during the Cosmic Dawn and put an end to the cosmic "dark ages" that followed the Big Bang. However, the distribution of their mass is one of the great unsolved mysteries of the cosmos.
