The scientists searching for life on Jupiter

Could there be life in Jupiter’s clouds? A study into possible life on Venus has shown that nothing could survive on the planet. But scientists hope for more luck on the gas giant, Jupiter.

What’s happening

Last year, a new study added hope to the theory that there was once life on Venus.

A year on, it seems life is less likely. But the studies have led to a surprising breakthrough. There might not be life on Venus, but there might be on Jupiter.

Researchers from Queen’s University Belfast have been studying clouds on different planets.

Their research found that Jupiter’s clouds have the right water conditions to permit Earth-like life.

Dr John Hallsworth is one of the scientists working on the study. He explained: “One thing which we found which was unexpected was that the clouds of Jupiter actually have the right temperature and water activity combination to support active life.

“We absolutely hadn’t expected that.”

Jupiter is the biggest planet in the solar system and is the fifth planet from the Sun.

It is known as a gas giant because of its size – over 300 times greater than Earth. It also has gas rings and 67 moons.

Could there really be life in Jupiter’s clouds?

Some say…

Probably not. Jupiter is a gas giant. It has no solid ground. It can get as hot as 24,000C. The gases in the clouds are poisonous. The clouds are thick and the magnetic field is super strong. Even if life could exist in theory, there is no way anything could survive on the planet!

Others think…

Maybe! Life does not have to be exactly how we imagine it. Even though Jupiter would be an impossible home for humans, something different might love it there. The boiling temperatures and dangerous gases might be perfect for an alien lifeform. The best thing about the universe is that we know so little. Anything could be out there!
