Could any human dare to explore a planet that smells like rotten eggs? Scientists have discovered a planet close to Earth that does just that.
International media reported on an intriguing discovery in astronomy. Using the James Webb Space Telescope (JWST), scientists discovered a planet outside our solar system with the size of Jupiter. Roughly 64 light years from Earth, it is thought to smell like rotten eggs due to atmospheric irregularities.
The planet, known as HD 189733 b, is a blue planet that orbits its star in a mere 2.2 days. Its close proximity to its star – just 4.8 million kilometers (3% of the distance from Earth to the Sun) – results in a surface temperature of 1,700 degrees Fahrenheit (926.6 degrees Celsius).
According to a report in the journal Nature, the James Webb Space Telescope detected an exoplanet, a gas giant similar to Jupiter but larger and more massive, in the direction of the constellation Vulpecula.
The atmosphere contains hydrogen sulfide, a colorless, toxic and flammable gas. On Earth, it is found in decaying organic matter and volcanoes.
Dr. Guangwei Fu, an astrophysicist at Johns Hopkins University, stated: “We are not looking for life on this planet because it is too hot. However, the discovery of hydrogen sulfide is a significant step in searching for this molecule on other planets and understanding how different types of planets form. Moreover, we have measured the sulfur content of this exoplanet.
Sulfur is a key ingredient in the formation of complex molecules, alongside carbon, nitrogen, oxygen, and phosphate. Scientists need to study it to fully understand the formation and composition of planets.
The likely reason for the planet’s rotten egg smell, though not yet confirmed by scientists or astronauts, is the presence of hydrogen sulfide and sulfur.

A Planet That Smells Like Rotten Eggs?

Would you dare to explore a planet that smells like rotten eggs? Scientists have discovered an exoplanet, a planet outside our solar system, that emits the unmistakable aroma of sulfur.
The Discovery: A Smelly Gas Giant
Using the James Webb Space Telescope (JWST), a team of scientists have identified a gas giant similar to Jupiter, located approximately 64 light-years from Earth in the constellation Vulpecula. This planet, named HD 189733 b, is a blue planet that orbits its star in a mere 2.2 days. Its proximity to its star, just 4.8 million kilometers (3% of the distance from Earth to the Sun), results in a scorching surface temperature of 1,700 degrees Fahrenheit (926.6 degrees Celsius).
The most intriguing aspect of this discovery is the presence of hydrogen sulfide in the planet’s atmosphere. Hydrogen sulfide, a colorless, flammable gas, is also found on Earth in volcanic emissions and the decay of organic matter. It’s the same compound responsible for that notorious rotten egg smell.
Significance of the Discovery
While HD 189733 b is too hot to support life as we know it, the discovery of hydrogen sulfide holds significant implications for our understanding of planetary formation and the search for life beyond Earth.
Dr. Guangwei Fu, an astrophysicist at Johns Hopkins University, explains the importance of this discovery: “We are not looking for life on this planet because it is too hot. But the discovery of hydrogen sulfide is an important step in searching for this molecule on other planets and understanding better how different types of planets form. We have also measured the sulfur content of this exoplanet.”
Sulfur is a crucial element in the formation of complex molecules, alongside carbon, nitrogen, oxygen, and phosphate. Studying the sulfur content of exoplanets helps scientists unravel the mysteries of planetary formation and their constituent materials. This knowledge might be fundamental to future searches for habitable planets.
A Smelly Future for Exoplanet Exploration
Though scientists haven’t physically confirmed the scent of HD 189733 b, the detection of hydrogen sulfide and sulfur strongly suggests this planet likely gives off an unpleasant rotten egg aroma. This discovery adds a new dimension to our understanding of exoplanets, highlighting the diverse and sometimes unusual features they may possess.
The exploration of exoplanets continues to reveal fascinating and unexpected characteristics, pushing the boundaries of our knowledge regarding the universe. This discovery reminds us that our cosmic neighborhood is full of surprises, some fragrant, some not so much.
