Nasa scientists have found new evidence of the mysterious ‘Hydrogen Wall’ that surrounds all the planets and objects in our solar system.
This mysterious bubble marks the boundary between the solar system and interstellar space and provides a marker for the edge of the Sun’s influence.
According to the latest findings, the barrier is actually a vast amount of trapped hydrogen atoms caught up in the solar wind of our star.
These produce waves of ultraviolet light in a very distinctive way, which have been detected by the sensors aboard the New Horizons interplanetary space probe.
