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 ...
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 ...
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 ...
Astronomers are finding dozens of the fastest stars in our galaxy with the help of images from NASA’s Spitzer Space Telescope and Wide-field Infrared Survey Explorer, or WISE. When some speedy, ...

These Galactic Clusters Smashed Into Each Other. Giant Bow Shocks Suggest They're About To Go For Round 2
For anyone disappointed that the Milky Way – our host galaxy – may not collide with our closest neighbor Andromeda after all, we have good news to keep your collision-hungry minds satisfied.
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 ...
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 ...
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 ...
