1/ Using our Very Large Telescope (VLT), astronomers have discovered extremely powerful winds pummelling the equator of the giant gas exoplanet WASP-127b, 500 light-years away.

Reaching speeds up to 33 000 km/h, the winds make up the fastest jetstream of its kind ever measured on a planet.

In comparison, the fastest wind ever measured in the Solar System was found on Neptune, moving at 1800 km/h.

How did they do it? Keep reading...

Artist's impression by ESO/L. Calçada

Artist’s impression showing WASP-127b, a giant gas planet. The planet takes up almost the full frame, with its atmosphere showing whirling motion all over the planet. Wispy ripples of blueish white mixed with orange imply motion, with white being the dominant colour at the equator and the planet’s poles, and a band of more orange-red between them. In the black background are some tiny white stars.

2/ When the planet crosses between its host star and us, molecules in the planet's atmosphere absorb specific colours or wavelengths. These colours shift to blue if the molecules are moving towards us and red if they're moving away.

The spectrum of WASP-127b shows both blue- and redshifted features, meaning that part of the atmosphere is moving towards us while the other part is moving away. In other words: there is wind circling around the planet.

The larger the wavelength separation between the peaks in the spectrum, the faster the wind, which in the case of WASP-127b moves at an impressive 9 km per second.
