ESOcast 182 Light: ALMA and MUSE Detect Galactic Fountain (4K UHD)

Observations by ALMA and data from the MUSE spectrograph on ESO’s VLT have revealed a colossal fountain of molecular gas powered by a black hole in the brightest galaxy of the Abell 2597 cluster — the full galactic cycle of inflow and outflow powering this vast cosmic fountain has never before been observed in one system. 

The video is available in 4K UHD. 

The ESOcast Light is a series of short videos bringing you the wonders of the Universe in bite-sized pieces. The ESOcast Light episodes will not be replacing the standard, longer ESOcasts, but complement them with current astronomy news and images in ESO press releases.

  1. How stupid! These gases are PRIMORIDIAL and are not being "pumped" out of ANTHING!!! Its cosmic rays that are being pumped out to ionize the gas so you can see it, while the gases remain stationary. You IDIOTS!
