First detailed observation of the atmosphere of a planet 900 light years from Earth

Wind speeds many times faster than bullets leaving the barrel on the planet Tylos challenge humanity's understanding of how weather works on such distant worlds .

This simulates the weather on the planet Tylos, with the orange areas indicating temperatures exceeding 2,000 degrees Celsius.

Astronomers have for the first time mapped the planet's atmosphere in detail, revealing the fastest winds ever observed around a celestial body in the vast universe.

The results showed that a powerful, sodium-rich wind stream traveled at speeds exceeding 72,420 km/h along a narrow path along the equator of Tylos, an exoplanet located approximately 900 light-years from Earth. Meanwhile, the bullet's speed upon leaving the barrel was around 3,000 km/h.

Below the main airflow are slower-moving layers of wind containing titanium and iron.

No one could survive in the atmospheric conditions of the planet Tylos, according to a report published in the journal Nature .

Tylos is classified as a "superhot Jupiter," being so close to its central star that a year on the planet is equivalent to only 30 hours on Earth.

One side of the planet Tylos is locked onto its central star, causing daytime temperatures to consistently exceed 2,000 degrees Celsius. The other side is shrouded in perpetual darkness and is approximately 1,000 degrees Celsius. The boundary between day and night is always maintained in a state of twilight.

Researchers used the European Southern Observatory's (ESO) VLT telescope in Chile to collect light from the Tylos atmosphere reaching Earth. The data recorded was used to analyze the signatures of elements and compounds.

This is the first time Earth astronomers have been able to study the structure of the atmosphere of an exoplanet.

"The atmosphere of the planet Tylos behaves in ways that completely defy human understanding of weather patterns, not just on Earth but on all planets in the universe," according to ESO report author Victoria Seidel.
