Astronomers are excitedly waiting for a "new star" to appear in the sky soon. T CrB consists of a double star system: a white dwarf and a red giant. The white dwarf draws matter from the red giant, causing periodic nova explosions. According to historical records, this event repeats approximately every 80 years. Its last eruption occurred in 1946, and the next eruption is expected any time until September 2024.
T CrB is a mysterious nova because it enters a phase called 'high state' before and after the explosion. There is also a second, smaller explosion after the main explosion. This time, astronomers will be able to observe T CrB in more detail thanks to advanced technologies. This could yield new information about white dwarfs, novae, and even the crisis of cosmology. For this reason, the T CrB nova is not only a celestial event, but also a gateway to the universe.
