A Sense of Doubt blog post #2683 - Wall of Fire in Space?

I know I am a little late to the party on this news, although I will admit that I think I did read about it in late 2018 or early 2019.

Just hearing about a wall of fire in space sounds like something out of a pulp science fiction story, but once one understands the science of the sun and the solar system, it makes good sense.

Still, it's cool to think of boundaries to our local space as if they were not naturally occurring but out there by a race of alien beings that created us and watch over us.

It's very cool that Voyager still voyages and crossed the Heliopause and ventured beyond the "confines" of our solar system and into international space.

In 40,000 years, when humans may no longer exist, Voyager 2 will arrive in the vicinity of Proxima Centauri.

This is today's share.

Thanks for tuning in.

Enjoy.

OUR SOLAR SYSTEM IS BLANKETED IN A GIANT WALL OF FIRE

VOYAGER 2 BROKE THROUGH, BUT THE WALL COULD MAKE INTERSTELLAR TRAVEL DIFFICULT.

Literal Firewall

At the outermost edges of our solar system lies a barrier of super-hot plasma — a giant wall of fire from the Sun that defines the edge of interstellar space.

As Voyager 2 began its journey into interstellar space in late 2018, it recorded temperatures as high as 49,427 degrees Celsius (89,000 degrees Fahrenheit), according to Nerdist. And while the space probe seems to be fine, the plasma shield could pose a problem to NASA as it moves towards its planned interstellar mission.

Defining Boundaries

Scientists are just now measuring the plasma layer, which was created and is maintained by solar winds that blow outward from the Sun to form a giant bubble, according to research published this month in Nature Astronomy.

According to a release from NASA's Jet Propulsion Laboratory, the new research suggests that Voyager 2 may not actually be in interstellar space yet, but rather stuck in a wide transitional region made of incredibly hot, compact plasma just beyond the outer reaches of the solar system.

Blog Vacation Two 2022 - Vacation II Post #119

I took a "Blog Vacation" in 2021 from August 31st to October 14th. I did not stop posting daily; I just put the blog in a low power rotation and mostly kept it off social media. Like that vacation, for this second blog vacation now in 2022, I am alternating between reprints, shares with little to no commentary, and THAT ONE THING, which is an image from the folder with a few thoughts scribbled along with it. I am alternating these three modes as long as the vacation lasts (not sure how long), pre-publishing the posts, and not always pushing them to social media.

Here's the collected Blog Vacation I from 2021:

Voyager's Terrifying New Discovery SHOCKS The Entire Space Industry!

Jun 14, 2022

Future Unity

The Voyager 2 spacecraft is one of the testaments to human ingenuity! More than four

decades after launch, the spacecraft continues to function, even in the harshest

imaginable condition of deep space! Despite being billions of miles away, the tenacious

spacecraft continues to send back amazing and even terrifying discoveries to the

mission controllers on earth! One of the discoveries was a huge wall of fire when

Voyager 2 crossed the boundary of our solar system! What happens at this boundary,

and how do the events at this boundary affect us on the earth? Join us as we dive into

Voyager 2's discovery of a wall of fire at the edge of our solar system

89,000°F WALL OF PLASMA SURROUNDS OUR SOLAR SYSTEM

by Matthew Hart

Nov 20 2019 • 7:00 AM

Imagine you’re running the faucet above a sink, and picture specifically the way the falling water from the faucet continuously splashes outward against the bowl, creating a little area where the standing water in the bowl can’t invade. It turns out the Sun does kind of the same thing as the water falling from the faucet, only instead of flinging water outward, it flings solar wind in every direction, and instead of standing water around it, there’s a particle soup made up of interstellar plasma. And while scientists have known about this dynamic for years, they’ve now discovered, thanks to the Voyager 2 space probe, that the region around the outer edge of our “shield” made up of solar wind, which clashes with the interstellar plasma soup, consists of an 89,000 degree Fahrenheit wall of (low density) plasma.

The sphere of piping hot plasma—which, again, is low density, meaning Voyager 2 can pass right through it without a problem— is discussed in the video above from YouTuber and high school science, math, and computer science teacher, Anton Petrov. In the video, which comes via Digital Journal, Petrov discusses one of NASA’s latest discoveries, made when its Voyager 2 space probe (launched in ’77) began passing through a region surrounding our solar system known as the heliopause. In this region, Voyager 2 discovered the spherical wall of interstellar plasma, which Petrov calls a “wall of fire.”

That “wall of fire,” Petrov notes, can be thought of as “an actual physical physical barrier,” and is “almost like a wall of hot plasma and… cosmic radiation that suddenly jumps up as soon as we cross into the so-called interstellar space.” That wall of hot plasma ranges in temperature from 30,000 to 50,000 kelvin (roughly 53,000 to 89,000 degrees Fahrenheit), according to a paper published earlier this month in the journal Nature Astronomy. In the abstract for that paper, the authors say that “The [very local interstellar medium, a.k.a. the wall of hot plasma] is variable near the [heliopause] and hotter than expected. The abstract also notes that “Voyager 2 observations show that the temperature [in that region] is 30,000–50,000 K, whereas models and observations predicted a [very local interstellar medium] temperature of 15,000–30,000 K.”

Needless to say, we earthlings are ridiculously lucky to have that solar-wind shield. The heliosphere, which the Sun provides, blocks out 70% of the interstellar cosmic rays. If we didn’t have the heliosphere, those cosmic rays would otherwise charge in and interact with us here on Earth, causing a serious uptick in the amount of radiation we’d absorb.

It’s unclear how difficult this wall of hot plasma will make interstellar travel, once we decide to go beyond Mars and eventually leave our solar system, but considering both Voyager 2, and even Voyager 1 (also launched in ’77) made it through OK, it seems like at least our interstellar ships wouldn’t be too negatively affected. Although it’s unclear how the plasma wall will affect we biological beings. Regardless, the discovery is exciting because, as JPL notes, this is the “cosmic shoreline… where the environment created by our Sun ends and the vast ocean of interstellar space begins.”

What do you think of this temperature check on the massive plasma wall around our solar system? Does it provide any extra reason for you to never leave our solar system, or would you fly through it like Crowley from Good Omens driving through a wall of fire in his demonic Bentley?

- Days ago = 2547 days ago

- New note - On 1807.06, I ceased daily transmission of my Hey Mom feature after three years of daily conversations. I plan to continue Hey Mom posts at least twice per week but will continue to post the days since ("Days Ago") count on my blog each day. The blog entry numbering in the title has changed to reflect total Sense of Doubt posts since I began the blog on 0705.04, which include Hey Mom posts, Daily Bowie posts, and Sense of Doubt posts. Hey Mom posts will still be numbered sequentially. New Hey Mom posts will use the same format as all the other Hey Mom posts; all other posts will feature this format seen here.
