Gemini and DECam showcase a young Type Ia supernova‎

A star's explosive demise has added a shiny new feature to NGC 1433, a barred spiral galaxy approximately 50 million light-years away in the southern constellation Horologium (the Pendulum Clock). New images of supernova SN 2026ahvu from the U.S. Department of Energy–fabricated Dark Energy Camera (DECam) and the Gemini South telescope capture the explosion against its galactic surroundings, recording an event that is changing in appearance from night to night.
