NASA research reveals that the heliosphere, our solar system's protective bubble, may resemble a deflated croissant rather than a comet. This new model, based on the behavior of solar wind particles, ...

In a groundbreaking study, researchers have controlled and observed Kelvin waves in superfluid helium-4 for the first time. Using an electric field to manipulate nanoparticles trapped in vortex lines, ...

Astronomers have seen analogous bubbles around hot stars, dying stars and baby stars — but not sunlike stars. “We don’t see them around … average, everyday stars that might host life,” said astronomer ...

Astrospheres, analogous to the heliosphere that surrounds our solar system, are bubbles of plasma blown into interstellar space by stellar winds. These winds are responsible for numerous processes ...

Infrared image of the shockwave (red arc) created by the massive giant star Zeta Ophiuchi in an interstellar dust cloud. The tenuous winds of sun-like main-sequence stars are much more difficult to ...

Astronomers have, for the first time, detected stellar winds blowing from three main-sequence stars similar to the sun. The observation helped determine the rates at which these stars lose mass via ...

"Our estimated mass-loss rates can be used as a benchmark for stellar wind models and expand our limited observational evidence for the winds of sun-like stars." When you purchase through links on our ...

In addition to that, the distance to the stars makes it very difficult to disentangle the signal emitted by the astrosphere from the actual X-ray emission of the star itself, part of which is "spread" ...

(Nanowerk News) An international research team led by a researcher from the University of Vienna has for the first time directly detected stellar winds from three Sun-like stars by recording the X-ray ...
