Jupiter’s moon Europa is the target of several exploration missions that will be sending data back to Earth over the coming years. Find out more about this moon and what these missions are investigating by reading our free articles, courses and other resources.

As we explore the Solar System, it is important that we do not accidentally contaminate untouched and unspoilt extraterrestrial environments in any way. This is especially true when searching for evidence of life. This article explores the concept of ‘Planetary Protection’ and why it is critical for the future of space exploration.

As our understanding of life and its potential beyond Earth improves, attention is moving towards smaller bodies, including moons and dwarf planets in the outer regions of our Solar System. But how can we strike a balance between exploring these new worlds and ensuring they remain unspoilt?

Mars continues to be at the forefront of international space exploration programmes, but as plans to bring samples back from the red planet and perhaps even send humans there edge closer, how can we ensure we do not contaminate the very environment we’re interested in understanding more about?

The Inaugural International COSPAR Planetary Protection Week is 22–25 April so we’ve collated some FREE resources on protecting planetary bodies as humans explore extra-terrestrial environments.

Space exploration is full of possibilities, especially when searching for signs of life. But the reality is complex. What lies behind the many decisions that have to be taken to design and run a space exploration mission?

In April 2023, the European Space Agency launched the JUICE (JUpiter ICy Moons Explorer) mission. JUICE will explore the environment around Jupiter and study its three icy moons (Ganymede, Europa and Callisto). Could moons like these, orbiting giant gas planets, be habitable?

In the coming years, Jupiter’s moon Europa will be a focus for planetary exploration because of the tantalising possibility that it might harbour life. This article introduces you to this enigmatic moon and why space scientists and astrobiologists are excited about exploring it further.

At over 3100 kilometres across, Europa is the fourth largest moon of Jupiter and the sixth largest moon in our Solar System, rivalling the size of Earth’s moon. Of interest to many scientists, space enthusiasts and science fiction authors is the potential for a vast, global ocean to exist below Europa’s outer icy shell; but why do we think there...

Jupiter’s moon Europa has a distinctive icy surface, with a network of cracks, ridges and chaotic terrain. These features are formed by powerful gravitational forces from Jupiter that reshape the moon’s landscape and offer clues about its geological activity. This article explains these features and the processes that underpin them.

We are at the beginning of an exciting new phase of Solar System exploration, in which Jupiter’s enigmatic ocean moon Europa will be front and centre. Here we look at what two upcoming missions hope to achieve and why this is important for space scientists and astrobiologists.

The potential for an ocean on Jupiter’s moon Europa opens up the possibilities of it being habitable for life. With missions due to visit the moon in the coming decade, it is an exciting time for astrobiologists. This article explores why Europa might be a target in the search for life, and what the potential might be of finding it there.
