A spectacular cosmic event is on the horizon as the star system T Coronae Borealis, also known as the ‘Blaze Star,’ is expected to explode within days. Located 3,000 light-years away from Earth, this binary star system consists of a red giant and a white dwarf, and it offers North Americans a chance to witness a breathtaking display in the night sky.
Understanding the Star System
T Coronae Borealis comprises two distinct types of stars. The red giant is in its final stages of life, expanding significantly, while the white dwarf is the remnant of a star that has exhausted its nuclear fuel and is gradually cooling down.
The interaction between these two stars is crucial for understanding stellar evolution and the life cycle of stars.
The upcoming explosion is not a supernova but a different kind of event that highlights the complex dynamics within binary star systems.
This occurrence is particularly significant, as it happens approximately every 80 years.
NASA’s assistant research scientist, Rebekah Hounsell, emphasises the educational impact of this event, stating, “It’ll fuel the next generation of scientists.”
The explosion is caused by the white dwarf absorbing material from its companion red giant, leading to a thermonuclear explosion.
How to Observe the Event
Astronomers anticipate that the explosion will occur by the end of September, although the exact timing remains uncertain.
To witness this celestial phenomenon, viewers should locate the Northern Crown (Corona Borealis), where T Coronae Borealis is situated.
To find it, start by identifying the Big Dipper; following the curve of its handle will lead you to the bright star Arcturus, with Vega shining to the northeast.
The Northern Crown will be visible between these two stars, so make sure to escape light pollution for the best viewing experience.
