ESOcast 127 Light: Ageing Star Blows Off Smoky Bubble (4K UHD)
Channel: European Southern Observatory (ESO)
Date: 2017-09-20

Astronomers have used ALMA to capture a strikingly beautiful view of a delicate bubble of expelled material around the exotic red star U Antliae. These observations will help astronomers to better understand how stars evolve during the later stages of their life-cycles.

This short podcast takes a look at this important new result and what it means.

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.
