Gamma-ray burst buried in dust (artist’s impression)

An artist’s conception of the environment around GRB 020819B based on ALMA observations. The GRB occurred in an arm of a galaxy in the constellation of Pisces (The Fishes). GRBs are huge explosions of a star spouting high-speed jets in a direction toward the observer. In a complete surprise, less gas was observed than expected, and correspondingly much more dust, making some GRBs appear as “dark GRBs”.
