Astronomers discovered an extraordinary exoplanet resembling a 'hell planet' in 2013. WASP-76b, located 640 light-years away in Pisces, astonishes with its extreme conditions..

Extreme Heat and Iron Rain

WASP-76b orbits its star every 1.8 Earth days. Its dayside reaches temperatures over 2,000 degrees Celsius. This intense heat vaporises iron, which then condenses and falls as iron rain on the cooler night side.

The planet is tidally locked, meaning one side always faces its star. Intense winds encircle WASP-76b, transporting iron atoms through its atmosphere. Researchers from the University of Geneva have detected these iron winds using the ESPRESSO spectrograph on the European Southern Observatory's Very Large Telescope.

Advanced Observations and Findings

The study employed high-resolution emission spectroscopy to analyse the planet’s visible light spectrum. This technique revealed the presence of iron moving from the lower to upper atmospheric layers. The findings were published in Astronomy & Astrophysics.

Research into exoplanet atmospheres, like that of WASP-76b, helps us understand extreme planetary environments. This gas giant's unusual conditions offer insights into worlds with extreme radiation from their host stars.
