Toxic 2,400C 'hell planet' Wasp-76b that rains liquid iron found – and it would vaporise you instantly

A HELL planet 390 light years from Earth is so hot it has rain made of iron pellets, scientists have discovered.

The scorching world Wasp-76b has 10,000mph winds and temperatures reach over 2,000C at its surface – hot enough to vaporise you in seconds.

Its clouds continuously rain molten iron, according to experts in Swirzerland, who found the planet.

Researchers have identified an iron absorption line on the ultra-hot exoplanet, a world outside our solar system.

Published in the Nature journal, the findings suggest it could rain iron on the nightside of the planet.

Some days its surface temperature exceeds 2,400C, hot enough to evaporate metals.

But at night the cooler temperatures mean the vapour turns into drops of iron.

Wasp-76b is known as a hot Jupiter – a gas giant that orbits very close to its star.

As a result, the iron rain never hits a "surface", and instead sinks down to the planet's core where it quickly re-vaporises.

This is the first result with a new high resolution instrument mounted on the European Southern Observatory's Very Large Telescope (VLT) in Chile.

It's known as Espresso, or the Echelle Spectrograph for Rocky Exoplanets and Stable Spectroscopic Observations.

Astrophysicists have identified chemical variations between day and night on the planet.

They detected the trace of iron vapour just at the division between the daytime and the night-time sector of the planet.

David Ehrenreich, a researcher at the University of Geneva and the first author of the article, said: "However, surprisingly we do not see this iron vapour at dawn.

What is an exoplanet?

Here's what you need to know…

  • An exoplanet is a planet that is located outside of our Solar System and one that is orbitting its own star, like how Earth orbits the Sun
  • They are very hard to see with telescopes because they are often hidden by the brightness of their star
  • Nasa sent the Kepler space telescope into orbit with the purpose of finding Earth sized exoplanets that might support life
  • Over 4,000 exoplanets have been discovered so far and more missions to find even more exoplanets are planned
  • A good way to spot an exoplanet is to look for "wobbly" stars because a disruption to star light can indicate that a planet is orbitting it and therefore blocking out light on occasion
  • Expoplanets are very common in the Universe and the more we find that look like Earth the closer we get to knowing if we're not alone out there

"The only explanation possible for this phenomenon is that it rains iron on the dark side of this exoplanet with extreme conditions."

Jonay I Gonzalez Hernandez, a researcher at the Instituto de Astrofisica de Canarias, Spain, said: "Just like the moon around the Earth, this planet always keeps the same face towards its star as it rotates around it.

"This causes this extreme difference in temperature between day and night on the planet."

In other news, Nasa recently spotted a nearby Earth-like planet that humans could one day colonise.

Distant planets may host even more life than we have here on Earth, according to one shock study.

And, last year Nasa boss Jim Bridenstine admitted he believed Pluto should still be classified as a planet.
