Report: Scientists Find 'Hydrogen Wall' at End of Solar System

The end of our solar system might be marked by a "hydrogen wall," according to measurements by the New Horizon's spacecraft, Gizmodo reported.

"We assume there's something extra out there, some extra source of brightness," Southwest Research Institute's Randy Gladstone told Gizmodo. "If we get a chance with New Horizons, we can maybe image it."

New Horizons is reportedly nearly four billion miles from Earth, far beyond Pluto, measuring "a wall of hydrogen" where the waning of our Sun's energy is "creating a boundary where interstellar hydrogen piles up at the edge of the outward pressure caused by the solar wind's energy."

"When [scientists] looked into the distance away from the Sun, they saw an added brightness to the signal," Gizmodo reported. "This could be from hydrogen particles beyond the solar system interacting with the furthest reaches of the solar wind, creating what appears to be a boundary in the distance, according to the paper published this week in Geophysical Research Letters."

A similar measurement was taken by the Voyager explorer 30 years ago, according to Gizmodo.
