A giant hydrogen wall has been spotted at the edge of this Solar System, and scientists of NASA think that their new Horizon Spacecraft can witness it. The hydrogen wall is the outer limit surrounding the solar system, the zone where the bubble of solar wind of the Sun ends and a mass of too small interstellar matter busting through that wind develops, pressing inward. The powerful jets of matter and energy of the host star flow outward for a prolonged time after leaving the sun; far away surpassing the orbit of Pluto. But at a particular point they tail off and their capability to thrive back the dust particles and other matter, which includes mysterious, thin stuff floating around the walls of the galaxy, dwindles, and a visible boundary gets formed. On its other side, in direction to Sun’s movement across the galaxy, there’s a set-up of interstellar matter that has hydrogen.
As of now the researchers of NASA are quiet sure that the New Horizons; the probe that popularly scooped off former Pluto back in 2015, can view that boundary. Things that the New Horizons for sure sees is some extra UV rays signalling the two Voyager space-craft, as the researchers stated in a published paper back in 7th August, in the Geophysical Research Letters journal. He farthest travelling probes of NASA that launched way back in 1970; spotted right back in 1192. However, researchers also stated that the signal is yet to deliver a sure sign regarding the Hydrogen Wall, or what Voyager did.
All the three probes could have literally detected the ultra-violet ray from some other source lying much deeper in the galaxy, as written by researchers. New Horizons will keep up with scanning the Sky for the UV light twice in a year, as per researchers’ statement where reports are stated. But the onboard New Horizons instrument; Alice is responsible for this outcome and is way sensitive than anything that was offered before on board by Voyagers.
