Looking for magnetic fields on exoplanets

Up into space now, and looking for Earth MK. 2. The pace of discovery of rocky planets out in space like this one, or exoplanets as they’re known, has really accelerated over the past 10 to 15 years. Looking for signs of life, or that another planet might be habitable, astronomers have a list of criteria when deciding which planets to investigate further - whether another planet might have water for example. If it was so essential for life here on earth, it might hold the key to finding it elsewhere.
