The phenomenon of stellar bow shocks arises when high-velocity stars, known as runaway stars, traverse the interstellar medium at supersonic speeds. As these stars emit powerful stellar winds, the ...

Extremely interesting footage shows the bow shock wave around an F-104 Starfighter flying supersonic. As already explained in a previous article, Piercarlo “Capone” Ciacchi is the Director of Flight ...

The leading explanation for the origin of galactic cosmic rays is particle acceleration at the shocks surrounding young supernova remnants (SNRs), although crucial aspects of the acceleration process ...

A nearby white dwarf is generating three times more energy than expected, hinting at unknown magnetic processes.

It’s one of the first things any of us learn about astronomy – stars twinkle while planets don’t. However, other point-like objects in the radio sky also twinkle, or “scintillate,” including spinning ...

A team of astrophysicists led by Dr Kalliopi Dasyra discovered fast winds of molecular and atomic gas that were caused by the interaction of the jet of a supermassive black hole with interstellar ...

This Hubble Space Telescope image shows a bow shock around a very young star called LL Ori. Named for the crescent-shaped wave made by a ship as it moves through water, a bow shock can be created in ...
