Scientists have discovered tadpole-shaped jets coming out of the Sun that may help explain why the corona (the wispy upper atmosphere of our star) is so inexplicably hot.
Presented during FAPESP Week London, instrument created in São Paulo will be improved in collaboration with Russia and will measure solar flares; launch is scheduled for 2022.
The hunt for Earth-like planets, and perhaps extraterrestrial life, just got more precise, thanks to record-setting starlight measurements made possible by a National Institute of Standards and Technology (NIST) 'astrocomb.'
Volunteer working with the Backyard Worlds: Planet 9 project has found the oldest and coldest known white dwarf star, ringed by dust and debris.
The oldest and coldest known white dwarf -- an Earth-sized remnant of a sun-like star that has died -- could be the first known white dwarf with multiple dust rings. The discovery, made by a volunteer working with the NASA-led Backyard Worlds: Planet 9 project, forces researchers to reconsider models of planetary systems.
Feature describes the first fully kinetic model of plasma particles showing that fast reconnection can indeed occur in partially ionized plasma.
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.
