Event details

Stars are ever present and never changing in our night sky. But sometimes this changes and causes a big commotion, especially when the star is a bright star in an iconic constellation, as it happened with Betelgeuse.

Betelgeuse is one of the most recognisable stars in the night sky, a bloated red supergiant, that since last autumn and until a few weeks ago looked like it might be on the verge of exploding as a supernova. Prof Maurizio Salaris (ARI) will give us an insight into this star's story in his talk What's up with Betelgeuse? We will look at what we know about Betelgeuse and red supergiants in general, their internal structure, their brief and tumultuous life; and we will also discover that maybe some of these stars are not what they seem.

Given the current COVID-19 situation, this event is not taking place as a public NTU event. However, Prof M Salaris (ARI) will provide an online talk on this topic to everyone who is booked onto this event. We will email a link to the material on YouTube to everyone who has booked. We will be happy to answer questions posted during the talk.
