SDSU professor helps discover precursors to the tools we use to map the universe.
Astronomy & Astrophysics publishes the work of researchers from the University of Vienna, who have found a river of stars, a stellar stream in astronomical parlance, covering most of the southern sky. The stream is relatively nearby and contains at least 4000 stars that have been moving together in space since they formed, about 1 billion years ago.
What is a black hole? In an article that has just appeared in the journal Nature Astronomy, Ludwig-Maximilians-Universitaet (LMU) in Munich philosopher Erik Curiel shows that physicists use different definitions of the concept, depending on their own particular fields of interest.
Measurements of gravitational waves from approximately 50 binary neutron stars over the next decade will definitively resolve an intense debate about how quickly our universe is expanding, according to findings from an international team that includes University College London (UCL) and Flatiron Institute cosmologists.
Queen Mary University of London has led a study which describes the first direct measurement of how energy is transferred from the chaotic electromagnetic fields in space to the particles that make up the solar wind, leading to the heating of interplanetary space.
The option to measure the gravitational waves of two merging neutron stars has offered the chance to answer some of the fundamental questions about the structure of matter. At the extremely high temperatures and densities in the merger scientists conjecture a phase-transition where neutrons dissolve into their constituents: quarks and gluons.

Inside Earth's magnetic bubble, scientists have long been listening in on space sounds created by various electromagnetic waves, and now they've found one that booms like a drum.
The Earth's magnetic shield booms like a drum when it is hit by strong impulses, according to new research from Queen Mary University of London.
Earth's solid surface and moderate climate may be due, in part, to a massive star in the birth environment of the sun, according to new computer simulations of planet formation.
