Most Massive Stellar Black Hole in our Galaxy found

The image shows an artist’s impression of a massive star, shining brightly in a white-yellow colour, orbiting a stellar black hole. The star’s orbital path is elliptical, outlined faintly in blue, with the major axis oriented vertically. The black hole is only visible as a red circular outline, and is located towards the bottom of the ellipse.

Astronomers have identified the most massive stellar black hole yet discovered in the Milky Way galaxy. This black hole was spotted in data from the European Space Agency’s Gaia mission because it imposes an odd ‘wobbling’ motion on the companion star orbiting it. Data from the European Southern Observatory’s Very Large Telescope (ESO’s VLT) and other ground-based observatories were used to verify the mass of the black hole, putting it at an impressive 33 times that of the Sun.

Stellar black holes are formed from the collapse of massive stars and the ones previously identified in the Milky Way are on average about 10 times as massive as the Sun...

The basal ganglia are subcortical structures located at the base of the forebrain. They are comprised of the caudate and putamen, which both make up the striatum, as well as the globus pallidus, substantia nigra, and subthalamic nucleus. ‘Basal Ganglia’ by Casey Henley is licensed under a Creative Commons Attribution Non-Commercial Share-Alike (CC BY-NC-SA) 4.0 International License.

Researchers at the University of Iowa in a new study have linked a region in the brain to how humans redirect thoughts and attention when distracted. The connection is important because it offers insights into cognitive and behavioral side effects to a technique being used to treat patients with Parkinson’s disease.

The subthalamic nucleus is a pea-sized brain region involved in the motor-contro...

Unleashing Disordered Rocksalt Oxides as Cathodes for Rechargeable Magnesium Batteries

Unleashing Disordered Rocksalt Oxides as Cathodes for Rechargeable Magnesium Batteries

Researchers at Tohoku University have made a groundbreaking advancement in battery technology, developing a novel cathode material for rechargeable magnesium batteries (RMBs) that enables efficient charging and discharging even at low temperatures. This innovative material, leveraging an enhanced rock-salt structure, promises to usher in a new era of energy storage solutions that are more affordable, safer, and higher in capacity.

Details of the findings were published in the Journal of Materials Chemistry A on March 15, 2024.

The study showcases a considerable improvement in magnesium (Mg) diffusion within a rock-salt structure, a critical advancement since the denseness of atoms in this confi...

The mystery of how Pluto got a giant heart-shaped feature on its surface has finally been solved by an international team of astrophysicists led by the University of Bern and members of the National Center of Competence in Research (NCCR) PlanetS. The team is the first to successfully reproduce the unusual shape with numerical simulations, attributing it to a giant and slow oblique-angle impact.

Ever since the cameras of NASA’s New Horizons mission discovered a large heart-shaped structure on the surface of the dwarf planet Pluto in 2015, this “heart” has puzzled scientists because of its unique shape, geological composition, and elevation...
