Astronomy enthusiasts, mark your calendars! NASA has announced a celestial event that promises to be a “once-in-a-lifetime” experience. Sometime this summer, a rare nova explosion will light up the night sky, visible even to the naked eye.
The Blaze Star in Corona Borealis
The spotlight falls on T Coronae Borealis, affectionately known as the “Blaze Star.” Located approximately 3,000 light-years away in the constellation Corona Borealis (or the “Northern Crown”), this binary system is captivating scientists and stargazers alike.
The Dramatic Dance of Stellar Partners
T Coronae Borealis consists of two stellar partners: a white dwarf and an ancient red giant. The white dwarf, a compact remnant of a dead star, orbits its red giant companion. As the red giant sheds hydrogen, the white dwarf greedily accumulates it on its surface. Eventually, this hydrogen buildup triggers a thermonuclear explosion—a nova event.
Once Every 80 Years
According to NASA, the T Coronae Borealis nova occurs approximately once every 80 years. The last time Earth witnessed this cosmic spectacle was back in 1946. Now, after nearly eight decades, we’re on the brink of another eruption.
A Bright Show Close to Home
What makes this nova unique? Its proximity to Earth! Typically, these events occur far away and remain faint. However, T Coronae Borealis will erupt so close that astronomers anticipate a clear view of the energy release. Dr. Elizabeth Hays, chief of the Astroparticle Physics Laboratory at NASA Goddard, explains, “We can’t wait to get the full picture of what’s going on.”
How to Spot the Northern Crown
To witness this stellar fireworks, look west of the Hercules constellation. Start by locating the two brightest stars in the Northern Hemisphere—Arcturus and Vega. Draw a straight line from Arcturus to Vega, and you’ll arrive at Hercules and the Corona Borealis.
Remember, this cosmic spectacle won’t last long. Once it erupts, the Blaze Star will dazzle us for less than a week. So, keep your eyes on the night sky this summer—you won’t want to miss it!
