Extreme Environments: Searching for Habitable Worlds

In Extreme Environments: Searching for Habitable Worlds, astrobiologist Louisa Preston explores how life in extreme environments on Earth can provide clues for finding life on Mars. Scientists believe that if life can survive in Earth’s harshest conditions, similar life could exist on Mars. This exploration not only advances our search for life on Mars but also helps us better understand the origins of life on Earth and may lead to future innovations in space exploration.

Lesson Express

Q: What kinds of extreme environments on Earth are similar to the conditions found on Mars?
A: Some examples include the dry valleys in Antarctica, extremely acidic rivers, and deep caves, where life still manages to thrive despite harsh conditions. These examples show how life might survive in extreme Martian environments.

Q: Why is it important to study life in extreme environments on Earth?
A: By studying how life survives in extreme conditions on Earth, scientists can apply this knowledge to find life on Mars, which has similar harsh conditions, such as cold temperatures and limited water.

Q: What is the main goal of studying life on Mars?
A: The goal is to find evidence of life on Mars, which could help us understand how life began on Earth, and it may eventually lead to the possibility of human colonization or gardening on Mars.

Getting Started: Life on Earth and Mars

In Getting Started: Life on Earth and Mars, Professor Brian Cox explains the conditions that are required for life to begin. Learn how Earth and Mars had these conditions at the same time. Could life have started in two places at once? Or might the life on Earth have come from outer space? This video is excerpted from BBC’s The Planets, a series that explores the dramatic lives of the eight planets in our Solar System.

Postcards From the Surface of Mars
In Postcards From the Surface of Mars, Professor Brian Cox examines the geographic evolution of Mars, noting the vast canyon called Valles Marineris. He looks at photographs taken from the surface of Mars that look eerily similar to Earth: sunsets, clouds, and landscapes. There is, however, one glaring difference: no sign of water. This video is excerpted from BBC's Wonders of the Solar System, a spellbinding documentary series that explores the most extreme locations on Earth to explain how the laws of physics carved natural wonders across the Solar System.

Once a Red Planet, Always a Red Planet? The Birth of Mars
In Once a Red Planet, Always a Red Planet? The Birth of Mars, Professor Brian Cox explains how when Mars and Earth were born, they had similar atmospheres and were made of similar material, but the two planets took dramatically different paths. Learn how different Mars is from Earth, and how much Mars has changed in 4.6 billion years. This video is excerpted from BBC’s The Planets, a series that explores the dramatic lives of the eight planets in our Solar System.
