Today on our continuing tour of this true strange universe, an amazing huge feature in space: there is new evidence from NASA of a vast glowing wall of hydrogen at the outer boundary of our planetary system.
There’s a “hydrogen wall” at the edge of our solar system, and NASA scientists think their New Horizons spacecraft can see it.
That hydrogen wall is the outer boundary of our home system, the place where our sun’s bubble of solar wind ends and where a mass of interstellar matter too small to bust through that wind builds up, pressing inward. Our host star’s powerful jets of matter and energy flow outward for a long stretch after leaving the sun — far beyond the orbit of Pluto. But at a certain point, they peter out, and their ability to push back the bits of dust and other matter — the thin, mysterious stuff floating within our galaxy’s walls — wanes. A visible boundary forms. On one side are the last vestiges of solar wind. And on the other side, in the direction of the Sun’s movement through the galaxy, there’s a buildup of interstellar matter, including hydrogen.
… What New Horizons definitely sees, the researchers reported in a paper published Aug. 7 in the journal Geophysical Research Letters, is some extra ultraviolet light — the kind the researchers would expect such a wall of galactic hydrogen to produce. That replicates an ultraviolet signal the two Voyager spacecraft — NASA’s farthest-traveling probes, which launched in the late 1970s — spotted all the way back in 1992. …

This is clearly going to change a lot of what we do on Earth from now on. How can you do what you’ve always done, knowing there is a big glowing wall out there? How can anyone? We must do something about it, obviously. Ideas?
Update: We haven’t heard anything about the wall in the news this week, so the entire thing has probably moved on to some other solar system by now. 😉
