In an astounding revelation which has left astronomers and space enthusiasts reeling in amazement, the James Webb Space Telescope (JWST) has made a game-changer find regarding Betelgeuse — the mysterious red supergiant star which is found in the Orion constellation. The discovery is so earth-shattering that it's caused shockwaves throughout the scientific community and beyond.
A Star on the Brink?
Betelgeuse, the brightest star in the evening sky, has been a source of intrigue for centuries because of its gargantuan size and erratic nature. Late 2019 and early 2020 saw the star suddenly grow much fainter, setting off wild rumors: Was it on the verge of exploding into a supernova?
The fading was subsequently attributed to a colossal cloud of dust partly hiding the star, but fascination as to its wellbeing never really dissipated. Today, due to the unparalleled resolution and infrared sensitivity of JWST, astronomers have achieved their sharpest glimpse ever — and it is nothing short of breathtaking.
James Webb Peers Into the Heart of a Giant
With its potent infrared detectors, JWST looked beyond the dust and turbulence enveloping Betelgeuse to take photos and readings of the star's inner layers. What it found was a turbulent and unstable atmosphere — far more so than ever before conceived.
Researchers say that Webb found giant convective plumes — really, towering pillars of gas — erupting from within Betelgeuse. They're bigger and more turbulent than any ever seen on a star. Such instability indicates Betelgeuse is in its later life stages, nearer to a supernova explosion than thought before.
A Supernova Within Our Lifetime?
If Betelgeuse were to go supernova, it would be something that could be seen from Earth — even during the day. Although still unknown when this will happen (it might be tomorrow or 100,000 years from tomorrow), the data from JWST are that the star is showing signs in line with the last stages of evolution prior to such a disaster.
This is the most precise information ever gathered on a star in the late stages leading up to a possible supernova," Dr. Emily Martinez, an astrophysicist working on the Webb science team, said. "We're not predicting it's going to explode any moment now, but Betelgeuse is definitely a star worth keeping an eye on."
What Does This Mean for Earth?
Luckily for us, Betelgeuse is approximately 642 light-years away — near enough to blast us with a harmless fireworks display if it does go supernova, but remote enough to be of no danger to our planet. Still, the event would be historic. It would mark the first naked-eye supernova to be seen since 1604, and the first ever with the entire arsenal of contemporary scientific tools to watch it unfold in real time.
Astronomers internationally are already increasing levels of surveillance, and amateur astronomers are urged to monitor Orion over the next few months and years.
The World Watches the Skies
In a world often dominated by terrestrial concerns, moments like this remind us of the vast, mysterious universe we’re part of. The James Webb Space Telescope — still in its early years of operation — has already lived up to its promise, and its revelations about Betelgeuse could be just the beginning.
Whether Betelgeuse blows next year or in a thousand, this is certain: Earth's eyes — and the JWST — are watching.
