  Uranus stinks! Scientists discover a cloud of 'rotten egg gas' surrounding the planet.

  It’s a smell that make most people gag, but it seems that Uranus has the distinct aroma of rotten eggs.

  Scientists from the University of Oxford have discovered a cloud of hydrogen sulphide - the gas that gives rotten eggs their smell - surrounding the planet.

  While astronomers have previously theorised that Uranus’ clouds contain hydrogen sulphide, this is the first study to prove it.

  Unlike Uranus, Jupiter and Saturn have no hydrogen sulphide in their clouds, and instead have ammonia.

  These differences could provide key insights into how the planets formed.

  The researchers also speculated about what the effects of the levels of hydrogen sulphide around Uranus would be on humans.

  Dr Irwin said: “If an unfortunate human were ever to descend through Uranus’s clouds, they would be met with very unpleasant and odiferous conditions.

  “Suffocation and exposure in the negative 200 degrees Celsius atmosphere made of mostly hydrogen, helium, and methane would take its toll long before the smell.”
