The team at the Max Planck Institute for Astronomy (MPIA) in Germany have been looking for exoplanets to search for 'biosignatures' - evidence of alien life, past or present.

When it is completed, it will be the world's largest optical telescope, some five times larger than the top observing instruments in use today.

Just last month, NASA's planet-hunting spacecraft TESS detected TOI 700 e, the latest potentially habitable exoplanet 100 light-years away from Earth.

They noticed a small, periodic shift in the frequency of light it emits, which indicates the star is wobbling slightly due to a planet pulling on its gravity.

Dr Diana Kossakowski, the study's lead author, said: 'When we analysed the data of the star Wolf 1069, we discovered a clear, low-amplitude signal of what appears to be a planet of roughly Earth mass.

The Earth's magnetic field is largely generated by the superheated, swirling liquid iron that makes up its outer core, 1,900 miles (3,000 km) below our feet.
