Astronomers took this image as they were observing an extraordinary exploding star – a supernova – near the galaxy’s central yellow core! The star rapidly evolved from a supernova containing very little hydrogen to one that is hydrogen-rich — in just one year. This rarely observed metamorphosis was luminous at high energies and provides unique insight into the poorly understood final phases of massive stars. By studying similar galaxies we hold a scientific mirror up to our own, allowing us to build a better understanding of our galactic environment, which we cannot always observe, and of galactic behavior and evolution as a whole.

Did you see that start up!? Fun Fact: Hot gases exit the nozzle at 13X the speed of sound! The full-duration, 365-second test helped verify that the flight controller – the engine’s “brain” – can properly communicate with the rocket. This test also used a 3D-printed component on the engine as an ongoing effort to use advanced manufacturing techniques as a means of reducing engine construction costs. Credit: NASA
