NEW DELHI: The cosmos is offering a “once-in-a-lifetime” spectacle as Nasa anticipates the explosion of a star system anytime from now until September, T Coronae Borealis, also known as T CrB, expected to dramatically illuminate the night sky. This “nova outburst” represents a momentous event occurring roughly every 80 years, with the last explosion recorded in 1946.
This event centers around T Coronae Borealis, known colloquially as the “Blaze Star,” part of a binary system that includes a red giant and a white dwarf star. The former, a dying star nearing the end of its life cycle, sheds its outer layers, transferring material to the latter, leading to a dramatic increase in brightness – a process known as a nova.
William J Cooke, lead of Nasa’s Meteoroid Environment Office, elucidated the rarity and unpredictability of such events, saying, “However, T Coronae Borealis is one of 10 recurring novae in the galaxy… the star will get dimmer for just over a year before rapidly increasing in brightness.” The expected timeframe for this spectacle is between now and September, adding an element of suspense to its occurrence.
Typically invisible to the naked eye due to its distance—3,000 light-years away—T Coronae Borealis’s upcoming outburst will enable onlookers to view a brightness matching that of the North Star, Polaris, without the need for telescopes, a phenomenon likely to last several days.

Nasa plans to monitor the nova using the Hubble Space Telescope and the Neil Gehrels Swift Observatory, contributing to the understanding of mass transfers and thermonuclear runaways in such binary systems.
Astronomy enthusiasts are encouraged to acquaint themselves with the Corona Borealis constellation, where the nova will manifest as a bright new star. Updates and insights on this celestial event are to be shared via Nasa’s social media channels.
Updates on this imminent cosmic event will be shared via the NasaUniverse account on X, providing enthusiasts and researchers alike with real-time information.
Reflecting on the transformative nature of such phenomena, Cooke reminisced about witnessing Nova Cygni in 1975, an event that solidified his passion and career in astronomy. While Nova Cygni may not reoccur, the anticipated brightness from T Coronae Borealis offers a similar, awe-inspiring experience for current and aspiring astronomers alike.
