This Galaxy Looks Normal… Until You Zoom In

[00:00:01]There's a galaxy 100 million light-years away that looks like it's hiding something. It has a bright core, a faint hint of spiral structure, and a face covered in dark filaments of dust, but no spiral arms at all. This is NGC 1266, a lenticular galaxy caught between being a spiral and an elliptical. But, that's not what [music] makes it strange. NGC 1266 is a post-starburst galaxy, a rare phase where a galaxy [music] has young stars, but almost no star formation left. Only about 1% [music] of galaxies look like this. Astronomers think NGC 1266 collided with a smaller galaxy 500 million years ago.

The black hole woke up, turned into an active galactic nucleus, and began blasting the galaxy with powerful jets [music] and winds. Over time, those jets stripped the galaxy of star-forming gas and stirred the rest into turbulence so violent that new stars couldn't [music] form anymore. Hubble and other telescopes now see gas being blown out of the galaxy, [music] and the space between its stars looks shocked and disturbed. Only a tiny region in the core [music] still forms stars. Everything beyond it has gone silent. It's possible the black hole itself [music] is shutting the galaxy down, ejecting the very material needed to create new suns. NGC 1266 is a galaxy in transition, a place where starbirth is dying, and a quiet elliptical future is taking shape.
