A ‘Once-In-a-Lifetime’ Astronomical Event Will Be Visible This Summer

By: Sam Watanuki | Published: Jun 17, 2024

This summer, a rare celestial event will illuminate the night sky — a nova explosion visible to the naked eye.

Described as a “once-in-a-lifetime event” by NASA scientists, this spectacular display offers a unique opportunity for stargazers and budding astronomers to witness a white dwarf’s dramatic eruption.

Understanding a Nova

A nova occurs when a white dwarf star suddenly lights up due to a thermonuclear explosion. Unlike a supernova, which marks the death of a star, a nova is a dramatic ejection of accumulated material from a white dwarf.

This summer, the white dwarf in the T Coronae Borealis system will create this rare phenomenon.

The T Coronae Borealis System

T Coronae Borealis, also known as the “Blaze Star,” is a binary star system located around 3,000 light-years from Earth.

It consists of a white dwarf and a red giant. The red giant’s hydrogen is siphoned off and accumulated on the white dwarf’s surface over decades, leading to periodic nova eruptions.

A Spectacular Display

Scientists predict that the flash will be bright enough to see with the naked eye. This event will be the first nova observed from this system since 1946, offering a rare glimpse into such cosmic phenomena.

The Science Behind the Eruption

A nova happens when the white dwarf pulls enough hydrogen from the red giant to trigger a thermonuclear explosion. This process repeats approximately every 80 years for the T Coronae Borealis system.

The upcoming nova will be a striking display of this cycle, creating a spectacle similar to a nuclear bomb’s blast.

Observing the Northern Crown

To witness the nova, look for the Northern Crown constellation, also known as Corona Borealis. It appears as a horseshoe-shaped curve of stars west of the Hercules constellation.

On clear nights, this will be the prime location to see the nova’s bright flash.

Inspiring Future Scientists

“This event will create a lot of new astronomers out there,” said Rebekah Hounsell, an assistant research scientist at NASA.

The spectacle is expected to ignite curiosity and inspire a new generation of scientists, offering a hands-on experience with a rare astronomical event.

Citizen Scientists' Role

NASA encourages citizen scientists to observe and collect data on the nova. “It’s equally critical to obtain data during the early rise to eruption,” Hounsell noted.

Why This Nova is Special

Recurrent novae like T Coronae Borealis are rare, with very few repeating outbursts occurring within a human lifetime.

The close proximity of this nova, relatively speaking, makes it a unique opportunity for observation and study, highlighting the dynamic nature of our universe.

Preparing for the Event

Stargazers should prepare by finding a dark location away from city lights. Using binoculars or a small telescope can enhance the viewing experience.

The Last Nova in 1946

The last time a nova was observed from T Coronae Borealis was in 1946.
