Supersonic Winds on Exoplanet WASP-127b Break Records at 33,000 km/h
For the first time in history, astronomers have detected an exoplanet with winds blowing at an remarkable speed of 33,000 kilometers per hour. This groundbreaking revelation was made on WASP-127b, a gas giant located approximately 520 light-years from Earth. The findings, published in the international astronomy journal Astronomy & Astrophysics on January 21, 2025, were led by a joint research team including the University of Göttingen in Germany.
WASP-127b is a captivating celestial body. It is indeed 30% larger in diameter than jupiter, the largest planet in our solar system, yet its mass is only 16% of Jupiter’s, making it the lowest-density planet ever observed. Using the Very large Telescope (VLT) at the european Southern Observatory (ESO) in Chile, the team measured the supersonic winds near the planet’s equator.
The jet stream on WASP-127b is nothing short of unusual. At 33,000 km/h, it is indeed 75 times more powerful than the jet streams in Earth’s upper atmosphere, which typically reach speeds of 442 km/h. Even Neptune, known for its high-altitude winds of 2,000 km/h, pales in comparison.
“The supersonic jet stream circling the equator of WASP-127b is faster than that of any other planet, which is surprising,” said Lisa Nordmann, the lead astrophysicist of the study.“It provides new insight into the future.”
This discovery not only highlights the extreme conditions on exoplanets but also opens new avenues for understanding atmospheric dynamics beyond our solar system.

WASP-127b: The Scorching Hot jupiter with a Chilling Twist
In the vast expanse of the universe, WASP-127b stands out as a fascinating example of a hot Jupiter—a gas giant that defies the norms of our solar system. Discovered in 2016,this exoplanet has captivated astronomers with its extreme conditions and unique characteristics.
what Makes WASP-127b Unique?
WASP-127b is a hot Jupiter, a term used to describe gas giants similar to Jupiter but located perilously close to their host stars. Unlike our solar system’s Jupiter, which orbits the Sun at a safe distance, WASP-127b completes an orbit around its star in just four days. Its proximity to the star is a mere 5% of the distance between Earth and the Sun, resulting in scorching surface temperatures.
The planet’s most striking feature is its tidal locking, meaning one side perpetually faces the star while the other remains in darkness. This creates a dramatic temperature contrast: the day side sizzles at a blistering 1127°C, while the night side remains cold.
Atmospheric Composition and Dynamics
According to dr. David Cont, co-author of the study, “WASP-127b is mainly composed of hydrogen and helium, like Jupiter, but traces of more complex molecules such as carbon monoxide and water have also been identified in its atmosphere.”
The intense radiation on the day side drives the planet’s atmospheric dynamics, causing extreme weather patterns and chemical reactions.This phenomenon offers scientists a rare opportunity to study how such conditions affect the composition and behavior of exoplanetary atmospheres.

Why WASP-127b Matters
WASP-127b provides invaluable insights into the diversity of exoplanets and the extreme conditions they can endure. Its unique characteristics challenge our understanding of planetary formation and atmospheric behavior.

Headline: Blazing a Trail: A Conversation with Dr. Lisa Nordmann on the Record-Breaking Winds of WASP-127b
Subtitle: Diving deep into the frist-ever detection of supersonic winds on an exoplanet and what it means for our understanding of the universe.
Introduction:
In a groundbreaking revelation, astronomers have uncovered an extraordinary phenomenon on the exoplanet WASP-127b—winds blowing at a staggering speed of 33,000 kilometers per hour, a record for any planet in the universe. This remarkable find, made using the Very Large Telescope (VLT) at the European southern Observatory (ESO) in Chile, was led by a team that includes Dr. Lisa nordmann, a renowned astrophysicist from the University of Göttingen, germany. today, we sat down with Dr. Nordmann to discuss this incredible discovery and its implications on our understanding of the cosmos.
The Discovery of Supersonic Winds on WASP-127b
Q: Dr. Nordmann, your team has made history by detecting the fastest winds ever recorded on a planet. Can you walk us through this discovery?
A: Thank you. Indeed, this discovery is quite exciting. We used the VLT to observe the orbital infrared emission of WASP-127b, and through that, we were able to measure the velocities of the winds around the planet. The results were unexpected—we found strong evidence of wind speeds reaching up to 33,000 km/h, which is over 75 times faster than Earth’s strongest jet streams.
Q: What makes these winds so remarkable?
A: Several factors make these winds noteworthy. First, the sheer speed is unprecedented. Second, the winds are supersonic, meaning they travel faster than the speed of sound in the planet’s atmosphere, which creates a sonic boom effect. Lastly, these winds are at the equator, were we wouldn’t expect such extreme speeds due to the planet’s rotation slowing down the wind’s velocity.
The Unique Nature of WASP-127b
Q: This isn’t the first time WASP-127b has surprised us. It’s larger than Jupiter but has only 16% of its mass.how do you explain this?
A: WASP-127b is, indeed, a puzzle. its low density suggests it might be composed mainly of light elements, like hydrogen and helium, with very little heavier material. It’s possible that this light composition, combined with the planet’s strong gravitational pull, drives the intense winds we’re seeing. But we’re still working to fully understand this captivating planet.
Implications and Future Research
Q: What does this discovery tell us about planetary atmospheres in general?
A: It tells us that we’re still learning and that there’s more diversity out there than we expected. It also underscores the importance of studying exoplanets in detail, even those that might seem unremarkable, as they can tell us about processes and conditions we’ve never encountered before.
Q: What’s next for you and your team?
A: We’re eager to observe these winds again, and hopefully, with even more precision. We also plan to explore other exoplanets, hoping to find similar wind behaviors. Ideally, we’d like to observe multiple planets in the same system to understand how their winds interact.
Conclusion
Q: Dr. Nordmann, thank you for joining us today and for your invaluable contributions to our understanding of the universe.
A: Thank you. It’s been a pleasure.This discovery is just the beginning, and I’m excited about the many more mysteries we’ll unravel as we continue exploring the cosmos.
