Wonder of Science

The star RS Puppis captured by the Hubble Space Telescope. This Cepheid variable star changes brightness by almost a factor of five every 40 days, resulting in a "light echo" on the surrounding gas and dust.

@wonderofscience A light echo?!? I need to have a lie down now. That distances are som immense that light echoes hurts my brain.

@wonderofscience that is really an amazing visualization. To see light move!

@wonderofscience

Nothing, but NOTHING, will ever dim the awestruck face I have every time I see these photos. Hot damn. We are less than specks in a tiny time frame in the history of the universe.

We are all stardust.
