Astronomers observe a strong superflare from giant star
Using the Neutron Star Interior Composition Explorer (NICER) and various ground-based telescopes, an international team of astronomers have performed observations of a strong X-ray superflare which occurred in 2022 on a giant star known as HD 251108......»»
Improved spin and density correlation simulations give researchers clearer insights on neutron stars
When a star dies in a supernova, one possible outcome is for the remains to become a neutron star. Inside a neutron star, the protons and electrons combine into uncharged neutrons. This substance is called neutron matter......»»
Traces of a giant landslide deep in the southern Baltic Sea—researchers investigate a potential tsunami
Off the coast of Blekinge, in southern Sweden, at a depth of around 50–60 meters, the bottom sediment has scars that are tens of kilometers long and appear to have been caused by a huge submarine landslide. However, what caused this landslide and e.....»»
