The space has always been a mystery to us. Recently NASA discovered the outer boundary of our solar system called as hydrogen wall.
Earlier it was thought to be not properly defined. Now NASA has said that their New Horizon spacing has seen that invisible boundary which is located on the edge of our solar system.
The hydrogen wall has been said as the ge place where bubbles of solar winds cease to exist.
Solar winds are jets of matter as well as energy thrown out by jets.
According to scientists, beyond the pluto the solar winds merged with milky way's galactic energy but now they have proved that the matter as well as energy that the solar wind carry is collected in some regions that builds hydrogen wall.
The Sun which is mostly composed of hydrogen burnt to give energy and helium, an inert gas to Sun.
But scientist have said that it may not be a final discovery maybe New Horizon could have detected ultraviolet ray and not hydrogen wall.
