T Coronae Borealis, a binary star system located 3,000 light-years from Earth, is a ticking time bomb waiting to explode. And if the recurring nova follows its usual pattern, we can expect to see a new, albeit temporary, star appearing in our night sky any day now.
The bright star Betelgeuse, a prominent member of the Orion constellation, is set to be occulted by the asteroid Leona on December 11. This occurrence, expected to last no more than 10 seconds, will cause the star to temporarily vanish from sight, a phenomenon visible along a narrow path on Earth.
