At that time, there were no known stars in our galaxy that were expected to go supernova within the next 60-70 years.
However, it's important to note that predicting exactly when a star will go supernova is very challenging. Supernovae are relatively rare events, and their timing is difficult to determine with precision. Scientists generally monitor and study stars that are known to be in advanced stages of their evolution and have the potential to go supernova in the future, but making accurate predictions about specific timeframes is currently beyond our capabilities.
It's always a good idea to stay updated with the latest astronomical research and discoveries to learn about any new information regarding potential supernovae in our galaxy.
