New Horizons Spacecraft Sees Possible Hydrogen Wall at the End of the Solar System

Source: Gizmodo

As it speeds away from the Sun, the New Horizons mission may be approaching a “wall.”

The New Horizons spacecraft, now at a distance nearly four billion miles from Earth and already far beyond Pluto, has measured what appears to be a signature of the furthest reaches of the Sun’s energy—a wall of hydrogen. It nearly matches the same measurement made by the Voyager mission 30 years ago, and offers more information as to the furthest limits of our Sun’s reach.

“We assume there’s something extra out there, some extra source of brightness,” study author Randy Gladstone from the Southwest Research Institute told Gizmodo. “If we get a chance with New Horizons we can maybe image it.”

The Sun’s light sends charged particles outward, causing hydrogen particles in the space between planets to release characteristic ultraviolet light. But eventually, the Sun’s energy should wane, creating a boundary where interstellar hydrogen piles up at the edge of the outward pressure caused by the solar wind’s energy.

Have some science to distract and entertain you from our train wreck of a President.

It'd be my honor.

22. It takes oxygen for the bang to happen.

Most oxygen out there is in the form of water and is frozen.

6. Maybe one day when

we're sending humans to another planet we'll be able to pass through this and find out more.

Serious research into space propulsion is needed to make this possible and anti-matter or some kind of fusion drive would be nice.

But how do you unfold it?

in to unfold it.

7. Remember, although there may well be a concentration of hydrogen out there

It's still what we on Earth would term "hard vacuum".

11. I wish military spending would be cut and a portion of it would be spent on space exploration

scientific accomplishments rather than the building of war machines would be a much better focus for our patriotic urges. I'd love to see parades and holidays for scientific accomplishments rather than our military actions and loss.


As far as capitalism is concerned, I'd even be happier to buy a mattress or a bedroom set on a holiday sale associated with a day of science rather than a day of war and death - like Memorial Day. Why would I feel compelled to spend money and have a good time on a day that is meant to commemorate the death of people I served with or led in combat?

25. What I was thinking

is using the space force to suck defense spending into making such possible.

Much bigger amount of money to build ships, bases and to do real exploration.

Maybe one day it could become the federation of planets.

27. link with more explanation:

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.

29. Wouldn't it be awesome to learn that Earth is some sort of prison colony planet

And that on the other side of this Hydrogen Wall, it's like this Utopian universe. Did I just write a script for the next great SciFi novel?
