Supersonic winds on Exoplanet WASP-127b: A Weather Phenomenon Beyond Imagination
Tornadoes and typhoons on Earth are known for their destructive power, but they pale in comparison to the extreme weather conditions observed on the distant exoplanet WASP-127b. Located approximately 520 light-years from Earth, this gas giant boasts equatorial winds reaching a staggering 33,000 kilometers per hour—nearly 6 times the planet’s rotation speed and the fastest supersonic jet stream ever recorded on any planet.
A Glimpse into WASP-127b’s Extreme Atmosphere

Discovered in 2016, WASP-127b is classified as a “hot Jupiter”, a type of exoplanet with no solid surface and an atmosphere dominated by dense gases. Despite being 30% larger in diameter than Jupiter, it has only 16% of Jupiter’s mass, making it one of the least dense planets ever observed. This “marshmallow planet” orbits extremely close to its host star, resulting in an average atmospheric temperature of 1,127°C.
Using the very Large Telescope (VLT) in chile, astronomers have uncovered unprecedented details about WASP-127b’s weather patterns. Lisa Nortmann, a scientist at the University of Göttingen and lead author of the study, explains: “Part of the planet’s atmosphere is moving towards us at a high speed, and another part is moving away from us at the same speed. Measurements show that there is an extremely powerful supersonic jet wind around the planet’s equator.”
Comparing Winds Across the Cosmos
To put WASP-127b’s winds into perspective, Earth’s strongest jet streams, found in the tropopause or stratosphere, reach speeds of 442 kilometers per hour. Even neptune, home to the solar system’s fastest winds, tops out at 2,000 kilometers per hour. Yet, these pale in comparison to the 33,000 km/h equatorial jets of WASP-127b.
| Planet | Wind Speed | Location |
|——————-|———————-|—————————-|
| earth | 442 km/h | Tropopause/Stratosphere |
| Neptune | 2,000 km/h | Atmosphere |
| WASP-127b | 33,000 km/h | Equatorial Jet Stream |
Complex Weather Patterns and Atmospheric Clarity
WASP-127b’s weather is as complex as it is indeed extreme. Like earth’s moon, the planet is tidally locked, meaning one side always faces its star while the other remains in perpetual darkness. This creates a stark temperature contrast, with cooler poles and slight variations between morning and evening temperatures.
Previous studies have also revealed that WASP-127b’s atmosphere contains high concentrations of sodium, potassium, and lithium. the broad absorption spectral lines of sodium and potassium suggest a remarkably clear sky, offering scientists a rare prospect to study the planet’s atmospheric composition in detail.
Implications for Exoplanet Research
understanding the weather dynamics of exoplanets like WASP-127b provides valuable insights into heat redistribution and chemical processes in extreme environments. These findings not only enhance our knowlege of planet formation but also pave the way for future discoveries about the diversity of planetary systems beyond our solar system.
The study, published in the journal Astronomy & Astrophysics, marks a meaningful step forward in exoplanet research.For more details, explore the findings on the european Southern Observatory’s website.

Supersonic Winds on Exoplanet WASP-127b: A Deep Dive into Extreme Whether Phenomena
Exoplanet WASP-127b,located 520 light-years from Earth,has captured the attention of astronomers with its extreme weather conditions. Equatorial winds reaching an astonishing 33,000 kilometers per hour make it a captivating subject for studying atmospheric dynamics in extreme environments. In this interview, Senior Editor Sarah carter from world-today-news.com sits down with Dr. Emily Harper, an astrophysicist specializing in exoplanetary atmospheres, to discuss the groundbreaking findings about WASP-127b and thier implications for exoplanet research.
Unprecedented Wind Speeds on WASP-127b
Sarah Carter: Dr. Harper,the winds on WASP-127b are unlike anything we’ve seen before. Can you explain how these supersonic jet streams were discovered and what makes them so extraordinary?
Dr. Emily Harper: Absolutely, Sarah. Using the Very Large Telescope (VLT) in Chile, astronomers were able to measure the Doppler shifts in the planet’s atmosphere. They found that part of the atmosphere is moving toward us at high speeds, while another part is moving away. This creates an extremely powerful equatorial jet stream, clocking in at 33,000 km/h. To put this into outlook, Earth’s strongest jet streams reach only 442 km/h, and even Neptune’s winds, the fastest in our solar system, max out at 2,000 km/h.This finding is groundbreaking as it challenges our understanding of atmospheric dynamics in gas giants.
The Marshmallow Planet: WASP-127b’s Unique Characteristics
Sarah Carter: WASP-127b has been described as a “marshmallow planet” due to its low density. What does this tell us about its composition and formation?
Dr. Emily Harper: WASP-127b is indeed a fascinating object. Despite being 30% larger in diameter than Jupiter, it has only 16% of Jupiter’s mass, making it one of the least dense planets ever observed. This low density suggests that its atmosphere is dominated by light gases, possibly hydrogen and helium, but with meaningful amounts of heavier elements like sodium, potassium, and lithium. Its proximity to its host star also means it has an average temperature of 1,127°C,which likely contributes to its puffy,marshmallow-like structure. Understanding how such a planet forms and evolves can provide insights into the diversity of planetary systems.
Complex Weather Patterns and Atmospheric Clarity
Sarah Carter: The weather on WASP-127b seems incredibly complex. How does being tidally locked affect its atmospheric conditions?
Dr. Emily Harper: Being tidally locked means one side of WASP-127b always faces its star, while the other side remains in perpetual darkness. This creates a stark temperature contrast between the day and night sides, leading to powerful winds that redistribute heat. Interestingly, we’ve also detected broad absorption lines of sodium and potassium in its atmosphere, indicating remarkably clear skies. This clarity allows us to study its atmospheric composition in unprecedented detail, offering a rare opportunity to understand chemical processes in extreme environments.
Implications for Exoplanet Research
sarah Carter: What do these findings mean for the future of exoplanet research?
Dr. Emily Harper: These discoveries are incredibly valuable for advancing our understanding of heat redistribution and chemical processes in exoplanetary atmospheres. By studying extreme environments like WASP-127b, we can refine our models of planet formation and evolution. Additionally, these findings highlight the potential for discovering even more diverse and exotic worlds beyond our solar system. The study, published in Astronomy & Astrophysics, is a significant step forward in our quest to unravel the mysteries of the universe.
