Scientific Red Flag Spotted in Milky Way’s Dark, Dusty Center – Oddity Moving in the Direction of Earth

Milky Way Galaxy

Scientific ‘Red Flag’ Reveals New Clues About Our Galaxy

Figuring out how much energy permeates the center of the Milky Way — a discovery reported in the July 3 edition of the journal Science Advances — could yield new clues to the fundamental source of our galaxy’s power, said L. Matthew Haffner of Embry-Riddle Aeronautical University.

The Milky Way’s nucleus thrums with hydrogen that has been ionized, or stripped of its electrons so that it is highly energized, said Haffner, assistant professor of physics & astronomy at Embry-Riddle and co-author of the Science Advances paper. “Without an ongoing source of energy, free electrons usually find each other and recombine to return to a neutral state in a relatively short amount of time,” he explained. “Being able to see ionized gas in new ways should help us discover the kinds of sources that could be responsible for keeping all that gas energized.”

University of Wisconsin-Madison graduate student Dhanesh Krishnarao (“DK”), lead author of the Science Advances paper, collaborated with Haffner and UW-Whitewater Professor Bob Benjamin — a leading expert on the structure of stars and gas in the Milky Way. Before joining Embry-Riddle in 2018, Haffner worked as a research scientist for 20 years at UW, and he continues to serve as principal investigator for the Wisconsin H-Alpha Mapper, or WHAM, a telescope based in Chile that was used for the team’s latest study.

To determine the amount of energy or radiation at the center of the Milky Way, the researchers had to peer through a kind of tattered dust cover. Packed with more than 200 billion stars, the Milky Way also harbors dark patches of interstellar dust and gas. Benjamin was taking a look at two decades’ worth of WHAM data when he spotted a scientific red flag — a peculiar shape poking out of the Milky Way’s dark, dusty center. The oddity was ionized hydrogen gas, which appears red when captured through the sensitive WHAM telescope, and it was moving in the direction of Earth.

The position of the feature — known to scientists as the “Tilted Disk” because it looks tilted compared with the rest of the Milky Way — couldn’t be explained by known physical phenomena such as galactic rotation. The team had a rare opportunity to study the protruding Tilted Disk, liberated from its usual patchy dust cover, by using optical light. Usually, the Tilted Disk must be studied with infrared or radio light techniques, which allow researchers to make observations through the dust, but limit their ability to learn more about ionized gas.

“Being able to make these measurements in optical light allowed us to compare the nucleus of the Milky Way to other galaxies much more easily,” Haffner said. “Many past studies have measured the quantity and quality of ionized gas from the centers of thousands of spiral galaxies throughout the universe. For the first time, we were able to directly compare measurements from our Galaxy to that large population.”

Krishnarao leveraged an existing model to try and predict how much ionized gas should be in the emitting region that had caught Benjamin’s eye. Raw data from the WHAM telescope allowed him to refine his predictions until the team had an accurate 3-D picture of the structure. Comparing other colors of visible light from hydrogen, nitrogen and oxygen within the structure gave researchers further clues to its composition and properties.

At least 48 percent of the hydrogen gas in the Tilted Disk at the center of the Milky Way has been ionized by an unknown source, the team reported. “The Milky Way can now be used to better understand its nature,” Krishnarao said.

The gaseous, ionized structure changes as it moves away from the Milky Way’s center, researchers reported. Previously, scientists only knew about the neutral (non-ionized) gas located in that region.

“Close to the nucleus of the Milky Way,” Krishnarao explained, “gas is ionized by newly forming stars, but as you move further away from the center, things get more extreme, and the gas becomes similar to a class of galaxies called LINERs, or low ionization (nuclear) emission regions.”

The structure appeared to be moving toward Earth because it was on an elliptical orbit interior to the Milky Way’s spiral arms, researchers found.

LINER-type galaxies such as the Milky Way make up roughly a third of all galaxies. They have centers with more radiation than galaxies that are only forming new stars, yet less radiation than those whose supermassive black holes are actively consuming a tremendous amount of material.

“Before this discovery by WHAM, the Andromeda Galaxy was the closest LINER spiral to us,” said Haffner. “But it’s still millions of light-years away. With the nucleus of the Milky Way only tens of thousands of light-years away, we can now study a LINER region in more detail. Studying this extended ionized gas should help us learn more about the current and past environment in the center of our Galaxy.”

Next up, researchers will need to figure out the source of the energy at the center of the Milky Way. Being able to categorize the galaxy based on its level of radiation was an important first step toward that goal.

Now that Haffner has joined Embry-Riddle’s growing Astronomy & Astrophysics program, he and his colleague Edwin Mierkiewicz, associate professor of physics, have big plans. “In the next few years, we hope to build WHAM’s successor, which would give us a sharper view of the gas we study,” Haffner said. “Right now our map `pixels’ are twice the size of the full moon. WHAM has been a great tool for producing the first all-sky survey of this gas, but we’re hungry for more details now.”

In separate research, Haffner and his colleagues earlier this month reported the first-ever visible-light measurements of “Fermi Bubbles” — mysterious plumes of light that bulge from the center of the Milky Way. That work was presented at the American Astronomical Society.

  1. Could that be Einstein’s sneaky action at a distance?

    • Torbjörn Larsson | July 4, 2020 at 3:25 pm | Reply

      I think you mean Newton’s action at a distance, which is a property of classical physics – and modern quantum physics – fields. There isn’t any description of entanglement, which is what Einstein referred to.

      They are looking for an energy source. It is unlikely to be a quantum field. The LINER-like emissions in galaxies are not attributed to active galaxy nuclei – and here it starts away from the galactic center – but to distributed sources (could be giant stars, or what have you) [ https://arxiv.org/abs/1109.1280 ]

    Did we instantiate any (laser?) photon event streams to capture intelligence via atmosphere.. I would whisper quantum but that is not even fempto-scale vs. temporal presence of the core.

  4. People think it’s a joke but in all reality the Lord Jesus Christ will soon return

    • I don’t disagree while adding The Lord is integral to our presence; Jesus Christ strives to Live through OUR Hearts , words, deeds – So that we can know our incredible potential as the children of God. Many people are awakening to clues indicating Christ returns via OUR Christ-like ascent; our collective consciousness and bliss found being unified in the knowledge WE ARE CHRIST – we are of the same intelligent, loving energy source – and capable of manifesting our reality. When it boils down to it, I see only two forms of matter from which everything is formed:

    What I dont get is how Hydrogen is striooed of Electrons (Plural) when it only has 1 elevtron and without that 1 electron its only a Proton and not Hydrogen at all? Ut should be inpossible to Ionise Hydrogen because there is only 1 electron????

    • I was with you on this thought. I think it’s an oversight or perhaps shorthand for “many single electrons from single hydrogen atoms” but I’m leaning toward the former.

    • Torbjörn Larsson | July 4, 2020 at 3:34 pm | Reply

      Hydrogen is often a molecule of di-hydrogen. Hence the molecule can lose two electrons.

      In “our lifetimes”? The galactic center is 50,000 light years away, so it takes even light 50,000 years to get here.

      From the article: “The structure appeared to be moving toward Earth because it was on an elliptical orbit interior to the Milky Way’s spiral arms, researchers found.” In other words, the gas is in an orbit – which it will no easily leave – around the center of the galaxy, far away from us.

      Really, the title and the article is just trying to be interesting. The way to beat that is to try to learn how to read this stuff.

      • Torbjörn Larsson | July 4, 2020 at 3:40 pm | Reply

        I should add that even if the physics is limited – part of an odd system at the center of the galaxy – it is somewhat interesting (tells about where the dominant center activity drops off). But not as much as the title would lead you to believe.

      Not at all. I got interested in cosmology again when they found dark energy some years ago, and the old big bang universe cosmology was replaced by the modern inflationary big bang cosmology for sure. It took a year to get up to speed, but then again I like to read the science papers directly.

  19. Hmm Ionized plasma… hmm 12k year cylcles and the Ridge Study (2019 nov I think) that shows waves in out glactic sheet that hit us roughly 11.5k years ago and tossed all kind’s of fun at us and possibly super heated plasma due to a direct hit to our star (aka 1700c + damage on most older the 11k+ structures ). Bad news boys and girls it’s not a “blackhole” in the middle of 1/3 of galaxies there much scarier Quasars type and if that’s the case we are now just seeing the gas ionized and I’d put it 1k to as little as 500 years before we are well (inset your catastrophe) don’t worry tho we should be getting the faster heavyer particals to confirm this in the next 5-10 years. Now these will cause things in the entire solarsystem to heat up o wait (Mars2017 study/Global warming on earth (I wonder) co2 is still way below some of earth spikes in ice cores and lava cuts over a 25k year time span (deep core 2016-2020 study)temperature rising and new storms on our gas big boys out there …remeber we are already seeing the light. Now I am not trying to scare not at all and I can refer to almost 200 study that point at the elephant in the room.

      This isn’t directly about central super massive black holes and the quasars active such galactic centers make. Nor is it a threat to us, the article says explicitly the observed gas is in an elliptic orbit around the galactic center.

    According to the article, “… free electrons usually find each other and recombine to return to a neutral state in a relatively short amount of time”.

    But electrons are negatively charged and they repel each other. How could they possibly “recombine” and become neutral? This makes no sense at all.

    • Anton Szautner | July 6, 2020 at 12:21 pm | Reply

      The free electrons recombine with ionized atoms which are missing electrons in their electron shells because they are struck by energetic photons which kick them out, which is why there are so many free electrons available. The ionized atoms are POSITIVELY charged and readily welcome the negatively charged electrons. But I would agree that was inadequately described in the article.

    The hyped blather in the pop “news” about the visible portion of the structure “headed for Earth” is pathetic and as excruciating as ever. Pointing that out is just as significant to the actual story as noting that half the kids riding on a merry-go-round in Los Angeles are moving toward mystified observers in New York. Gee, what a tremendous coincidence! It is obvious we must be very special and hold a privileged position in the cosmic scheme of things: “THEY” are aiming straight at us!
