Estrela vai desencadear enorme explosão termonuclear
March 27, 2025 - Uma estrela situada a 3.000 anos-luz da Terra poderá tornar-se visível a olho nu a 27 de março – uma oportunidade única na vida de observar uma explosão de nova que só ocorre a cada cerca de 80 anos
Astronomers predict a star located 3,000 light-years from Earth is about to become visible to the naked eye for the first time in almost 80 years – a once-in-a-lifetime viewing opportunity caused by a massive thermonuclear explosion.
Forecast to happen on March 27, the event will be triggered by T Coronae Borealis (T CrB) – a binary system where a white dwarf star is collecting matter from an unstable and nearby red giant – eventually setting off a nova burst that will be visible from Earth.
T CrB, last exploded in 1946, with astronomers historically observing it doing the same thing in 1866 and 1787 – meaning we’re due another one about now.
