Scientists from NASA has identified a layer of hydrogen wall covered on all the planets and objects in the solar system.
In the past, the New Horizon space probe travelled across Pluto then discovered filled space ‘Kuiper Belt’. Then NASA believed that a structure covering the outer solar system region. But, New Horizons detected a distinctive ultraviolet glow called the Lyman-alpha line. These produced by solar photons hitting the hydrogen atoms and scattering in 2017.
Solar system surrounded by Hydrogen wall
An ultraviolet captured with New Horizon space probe Alice UV spectrometer. It was the strongest evidence to prove that a layer between solar system and outer space is “Hydrogen wall”
The hydrogen wall considered as an utmost border of the solar system called as “Heliopause”.But the space consists an extremely low pressure where solar winds push back to the outer space.
The other side of the boundary heliopause there are neutral hydrogen atoms travelling through the interstellar space and slowdown in reaching close the boundaries meant to be congested and prepare to build another heliopause.
This phenomenon occurs during the sunlight travel across the solar system. The detection of ultraviolet isn’t new already identified by the voyager long ago.
The background glow could be something else, farther away out there in space; the only way to be sure is to do more sciencing. Which means more Alice observations with New Horizons – around twice a year for the foreseeable future.
The probe’s next encounter with a Kuiper belt object named Ultima Thule minor planet.
New Horizons won’t reach that point until sometime after, but if it’s still in operation, it may be able to take more observations as it moves more deep into.
