Distant, spiralling stars give clues to the forces that bind sub-atomic particles

Space scientists at the University of Bath in the UK have found a new way to probe the internal structure of neutron stars, giving nuclear physicists a novel tool for studying the structures that make up matter at an atomic level.
Neutron stars are dead stars that have been compressed by gravity to the size of small cities. They contain the most extreme matter in the universe, meaning they are the densest objects in existence (for comparison, if Earth were compressed to the density of a neutron star, it would measure just a few hundred meters in diameter, and all humans would fit in a teaspoon). This makes neutron stars unique natural laboratories for nuclear physicists, whose understanding of the force that binds sub-atomi ....

Ancient light illuminates matter that fuels galaxy formation

E-Mail
ITHACA, N.Y. - Using light from the Big Bang, an international team led by Cornell University and the U.S. Department of Energy s Lawrence Berkeley National Laboratory has begun to unveil the material which fuels galaxy formation.
There is uncertainty on the formation of stars within galaxies that theoretical models are unable to predict, said lead author Stefania Amodeo, a Cornell postdoctoral researcher in astronomy in the College of Arts and Sciences, who now conducts research at the Observatory of Strasbourg, France. With this work, we are providing tests for galaxy formation models to comprehend galaxy and star formation. ....

The storms, which consist of brightenings and broadenings of the dawn flank of an oval of auroral activity that encircles Jupiter s poles, evolve in a pattern surprisingly reminiscent of familiar surges in the aurora that undulate across Earth s polar skies, called auroral substorms, according to the authors.
The new study is the first to track the storms from their birth on the nightside of the giant planet through their full evolution. It was published today in ....

SwRI researcher theorizes worlds with underground oceans support, conceal life

SAN ANTONIO March 16, 2021 One of the most profound discoveries in planetary science over the past 25 years is that worlds with oceans beneath layers of rock and ice are common in our solar system. Such worlds include the icy satellites of the giant planets, like Europa, Titan and Enceladus, and distant planets like Pluto.
In a report presented at the 52nd annual Lunar and Planetary Science Conference (LPSC 52) this week, Southwest Research Institute planetary scientist S. Alan Stern writes that the prevalence of interior water ocean worlds (IWOWs) in our solar system suggests they may be prevalent in other star systems as well, vastly expanding the conditions for p ....

Radio telescopes are the world s most sensitive radio receivers, capable of finding extremely faint wisps of radio emission coming from objects at the farthest reaches of the universe. Recently, a team of astronomers used the National Science Foundation s Karl G. Jansky Very Large Array (VLA) to take advantage of a helping hand from nature to detect a distant galaxy that likely is the faintest radio-emitting object yet found. ....
