Supersonic Winds on WASP-127b: The Fastest Jet Stream Ever Recorded
In the vast expanse of the Milky Way, about 520 light-years from Earth, lies a planet that defies inventiveness. WASP-127b, a gas giant orbiting a sun-like star, is home to the fastest jet stream ever recorded, with winds reaching a staggering 20,500 miles (33,000 km) per hour.These supersonic winds,swirling around the planet’s equator,are unlike anything observed in our solar system or beyond.
To put this into outlook, Earth’s jet stream, which can reach speeds of over 275 miles (442 km) per hour, pales in comparison. Even Neptune, known for its fierce winds of about 1,200 miles (2,000 km) per hour, is no match for the howling gales of WASP-127b. As astrophysicist Lisa Nortmann of the university of Göttingen in Germany explains, “There are very fast circumplanetary jet winds on this planet. The wind speeds are very high.”

WASP-127b is classified as a “hot Jupiter,” a type of exoplanet that resembles Jupiter in size but orbits extremely close to its parent star. With a diameter 30% larger than Jupiter’s but only 16% of its mass, WASP-127b is one of the least dense planets ever discovered. “WASP-127b is a gas giant planet, meaning it has no rocky or solid surface beneath its atmosphere,” says astrophysicist David Cont of the Ludwig Maximilian University of Munich.
The planet’s proximity to its star—just 5% of the distance between Earth and the sun—results in scorching temperatures. One side of WASP-127b is perpetually facing its star, reaching temperatures of about 2,060 degrees Fahrenheit (1,127 degrees Celsius), while the other side remains in eternal darkness. This extreme temperature gradient is believed to drive the planet’s atmospheric dynamics, including its supersonic winds.
What Fuels These Winds?
The primary energy source for WASP-127b’s winds is the intense radiation from its parent star. Though,as Cont notes,”answering the question of what drives these strong winds is challenging,as several factors influence wind patterns in exoplanet atmospheres.” Other elements, such as the planet’s composition and rotation, also play a role in shaping these powerful jet streams.
WASP-127b’s atmosphere, composed mostly of hydrogen and helium, also contains traces of complex molecules like carbon monoxide and water.These compounds, detected in the study, provide valuable insights into the planet’s atmospheric chemistry and dynamics.
A record-Breaking Revelation

Scientists Uncover Surprising Atmospheric Dynamics on Distant Exoplanet
In a groundbreaking study, researchers have unveiled new insights into the atmospheric dynamics of a distant exoplanet, revealing unexpected wind patterns and temperature variations. Using advanced observational techniques, the team tracked the speed of molecules in the planet’s atmosphere, shedding light on the complex interplay of winds and chemical processes.
The observations were made using the CRIRES+ instrument on the European Southern Observatory’s Very Large Telescope in Chile. By employing the transit method, the researchers monitored changes in the brightness of the planet’s parent star as the exoplanet passed in front of it from Earth’s perspective. This approach allowed them to gather detailed data on the planet’s atmospheric composition and behavior.
“We are moving beyond inferring average properties,such as global mean temperature or chemical abundance,to exploring three-dimensional aspects of this atmosphere – for example,studying winds,temperature variations,and chemical processes at different longitudes and latitudes,” said one of the lead researchers.
The findings highlight the rapid advancements in exoplanet research, driven by improvements in instrumentation, observation techniques, and data analysis. “These results show how much remains to be discovered and how each new observation surprises this rapidly developing field,” the researcher added.
