There have been many must-see space events in the last year, such as the solar eclipse and the Aurora Borealis. Witnessing some celestial phenomena is not uncommon. Some occurrences, such as the Great Conjunction or Halley’s Comet, are so unusual that they only happen once in a lifetime. The fact that T Coronae Borealis, popularly referred to as the Blaze Star or T CrB, is approaching a cosmic explosion that would make it glow brighter than the North Star is why it’s such significant news. We might only ever witness this once, so if you blink, you might miss it. Astronomers reported in February 2016 that T CrB had reached a “phase of unprecedented high activity.” After eight years, specialists anticipate that solar Witnessing some celestial phenomena is not uncommon.

Astronomers reported in February 2016 that T CrB had reached a “phase of unprecedented high activity.” Experts now anticipate that, eight years later, solar activity may cause a nova outburst large enough to be seen with the unaided eye from Earth.
A white dwarf star absorbs solar material from a nearby red giant during a nova explosion. A thermonuclear explosion occurs when the temperature and pressure are too great. This causes the white dwarf to look brighter in the sky, but it does not explode; instead, the star returns to its initial brightness when the explosion has subsided. It’s a nova, that tremendous eruption.
For up to a week following its occurrence, the nova can be observed with the unaided eye. It will appear as though a new star has emerged in the sky during that time. NASA said the explosion could occur at any moment between now and September, day or night, though experts think it might take longer.
