T Coronae Borealis (‘T CrB’) is late to its expected brightening event, but recent research suggests an imminent outburst.T CrB, also known as the 'Blaze Star', is a recurrent nova that brightens once every 80 years.Located about 2,000 light-years away, the star typically spends most of its time below +10th magnitude.Although it's not expected to be the brightest star ever, its outburst will still be a rare and interesting celestial event.
