The ESO team has provided conclusive evidence linking cosmological gamma-ray bursts to hypernova explosions, suggesting a direct connection between the two events. The study uses unprecedented spectral data from the VLT KUEYEN telescope to determine the distance of the burst as approximately 2,650 million light-years.
Researchers have obtained near-infrared images of the hot spots in radio galaxy 3C 445 using advanced instruments on the VLT ANTU telescope. The images show synchrotron emission associated with an intergalactic shock, providing evidence of cosmic accelerators far from the galaxy and its main jets.
Astronomers uncover a star with extremely low element abundance, providing a unique window into the Milky Way's early stages. The discovery challenges current theories and offers hope for finding 'unpolluted' Big Bang material.
A star orbiting the massive Milky Way centre has been observed approaching the central black hole to within three times the distance between the Sun and Pluto. The new measurements provide conclusive evidence for the existence of a supermassive black hole at the centre of our galaxy.
A team of astronomers has directly observed a Dark Matter object, confirming the theory that it consists of small, faint stars in galaxies like our Milky Way. The detection was made using the Hubble Space Telescope and the European Southern Observatory's Very Large Telescope.
An international team of astronomers has discovered a very massive stellar black hole in the Milky Way Galaxy, weighing 14 times more than our Sun. The black hole is located in the binary system GRS 1915+105 and feeds on a low-mass star through a steady flow of stellar material.
A team of Belgian and French astronomers have discovered three distant stars with extremely high Lead abundances, exceeding other elements heavier than Iron. This finding aligns with current stellar models predicting the buildup of heavy elements in stellar interiors.
Scientists have successfully observed an optical coronal line from iron ions in a star called CN Leonis, located 8 light-years away. This achievement marks the first time such a detection has been made outside of our solar system and opens up new avenues for studying stellar cycles.
