(Phys.org)—A team of researchers affiliated with several institutions in Japan has found evidence showing that condensed aluminum oxide dust surrounding the star W Hydrae plays a key role in accelerating the stellar wind. ...
This spooky sight, imaged by the NASA/ESA Hubble Space Telescope, resembles fog lit by a streetlamp swirling around a curiously shaped hole – and there is some truth in that. While the 'fog' is dust and gas lit up by the ...
