Data sent back by the two Voyager spacecraft have shed new light on the structure of the Solar System.
Forty-two years after they were launched, the spacecraft are still going strong and exploring the outer reaches of our cosmic neighbourhood.
By analysing data sent back by the probes, scientists have worked out the shape of the vast magnetic bubble that surrounds the Sun.
The two spacecraft are now more than 10 billion miles from Earth.
Researchers detail their findings in six separate studies published in the journal Nature Astronomy.
