The Death of Our Own Star

Yt hubble has been observing this star for decades now, we can actually see the light echoes moving through this region. Can see how the shape of the bubbles that it has blown out are changing over time. We don't fully understand the pulsation mechanism these massive stars, but stars like myra can breathe in and out over the period of roughly a year in a rather irregular manner. And on the way back in, they do always bring every hum with them.
