A mysterious X-ray signal from the Perseus cluster of galaxies, which researchers say cannot be explained by known physics, could be a key clue to the nature of Dark Matter.

It really is incredible how one little line can spawn a multi-million dollar project. I love science.
ITS THE GETH
QUICK, LOCATE SHEPARD
Meh.. the Geth have been upstaged by The Darkness...skipped the Destiny beta I see.
30mmBalistic why are you talking to me???? who said you could talk to me? i need to fire them
Nicole Miller Meth head say what?
30mmBalistic I'll go with the Geth, since destiny seems to be using Mass Effects discarded storyline. ;) *shots fired*
Reaper reaper.
Why couldn't it be a new, unknown element being produced in such an extreme environment?
Could it be a previously undiscovered stable heavy element?
It appears that way.
An interesting hypothesis, but if that is the case, why only one spike in the readings? If it were a stable element, we would be seeing multiple spikes using the same technique that discovered this one. Then again, perhaps it is only detectable using certain means and this was a fluke.
Would be pretty bitchin if we could harvest some of this stuff. I have a feeling it would answer quite a few questions about a number of things.
+Adam Kelley Where would this 'new element' fit in the periodic table? In any case, there would have to be a huge mass of this material or phenomenon, for it to be detectable at such intensity and distance. Does that tell us more about its source?
I read papers of Bulbul and Boyarsky carefully. In my recent work I am going to check evidences for 7 keV sterile neutrino by counting dwarf X-ray galaxies. Preliminary results gives lower bound for DM particle mass - 7-8 keV.
One question: the mystery line was detected recently because of having better instruments (Chandra and other telescopes orbiting Earth) or because of the galaxies and clusters that are being observed?
This is certainly a very interesting discovery which warrants further investigation. While the researchers haven't been able to identify the emission line as being associated with known materials, that it is detected by multiple observatories is most important. Even if it turns out *not* to be dark matter emission, it would only open up a greater mystery to be solved.
What does this mean? Dynamic physics? (No constants?)
Astrophysicists might also consider laboratory plasma phenomena as a possible explanation, alongside new physics. In the laboratory, there are things like critical ionization velocities and state changes between dark, glow & arc modes. It's fine to suggest that cosmic plasmas are probably unlike laboratory plasmas in more than one regard, but at the inferential step, it seems only logical to at least consider electrical laboratory plasma physics explanations in our attempts to understand a highly ionized, superheated plasma which is observed emitting unexpected x-rays. After all, there are some plasma researchers (like Anthony Peratt) who insist that plasma phenomena do approximately scale over enormous magnitudes. And radio astronomer Gerrit Verschuur continues to publish on his claimed observations of critical ionization velocities associated with interstellar filaments -- which he insists will not be seen with some algorithmic approach.
To a person who views the universe as fundamentally gravitational, certain sudden large-scale changes are not expected. To a person who additionally or alternatively questions the cosmic plasma models, sudden, dramatic large-scale changes are still on the table, and there are many classical physics tools at their disposal to explain them. If the consistent choice that is made is to take observations which tend to refer to electricity -- ions, hot plasma, x-rays -- and to use that to point to dark matter, then as an outsider layperson looking in at this activity, I have to wonder what is going on here. The cosmic plasma models seem to be treated as unquestionable fact. They manage to completely escape questioning, even though they significantly deviate from our plasma observations from the laboratory.
If, as the researchers narrow in on this signal, they notice that it's originating from an object that involves twisting plasma filaments, then I don't mean this as disrespectful to any of the scientists involved in this research, but maybe it's time to question space's claimed electrical neutrality. Quasi-neutrality does not necessarily imply a lack of conductance ...

Amen Chris Reeve!
Nice! And If I may add... as a person "looking in", quit nullifying your accomplishments with poor sportsmanship.
But... if it radiates, then by definition it isn't dark matter, right?
Right so it can't be this "DARK MATTER" That they love to use to explain everything.
However it can be the signature of dark matter - i.e, an echo or distortion of space/time. As the article states - it isn't any known matter or transition of matter, hence it may be some form of artifact of an event or antimatter.
It would be like how we can verify the Higg's Boson. We can't 'see' the boson directly - only the effect of its presence or temporary existence. The shockwave of the event - not the cause of it. If that helps.
You are asking as if part of the problem is already solved, when nothing is actually. They have nothing but hints and clues.
seffard That's why it's call research honey. ;)
Nexus2Eden Yes, ok. Im not sure you know I meant to Wratched's comment.
how about the idea that everything in the whole of everything influences each and every part within the whole of everything as to influence and placement meaning no part is randomly placed but directed by the influence of a massive whole. there then is a reason for placement and function and influence and appearance.
Thank you!
Could this be some kind of communication?
Some people need lessons on history of science. First, the cycle of: we don't know something, so call it this or that, then look for what it may be, already happened many times. That's how science goes forward some times. If you don't want to accept it, that's your problem. Just make sure to educate yourself.
LOL. So you would like for them to say "Anomaly 384875?" That's too hard to remember. For now Dark Matter is the scientific name it shall have until it is explained. Headline: Update on "The we don't know what it is phenomenon" but have found something unbelievable". That title isn't too catchy. It also sounds ridiculous.
A lot of trolls in these feeds.
I wonder why these anti-science people even waste their time.
Of course their presence here makes about as much sense as the comments they make. So who knows, maybe they actually are interested in the world around us. They just don't have the knowledge & the world view to try to understand it.
Then again we have a word for people who learn stuff but cant understand it don't we.
ScienceRules Because they suck at science and denouncing it as rubbish is much easier for them than actually taking the time to learn it. JMO
Aliens.
Aliens 3 & 4

lol according to Michichu Kaku? xD
send in the marines!
Wait sorry for my ignorance but what can this possibly mean? A new element or demension? Or????
Or the sound of dark energy or dark matter.
Poptart. I bet it was a Poptart.
I'll like the video to pretend that I understood everything.
we proud of you! :)
String theory has no less than 10^60 explanations for it already. Win.
Q/Hermoso es el Universo, gracias por mostrarmelo, Tan Deslumbrante!!!!
Definitely Geth.
What? Something that scientists admit they don't know? Usually they give us some theory as a fact.
uhh I don't think you follow science that well. Unless you get your science articles from the Daily Mail, you'll see that scientists find things that they can't definitively explain and they admit it all the time. They usually just suggest a plausible hypothesis. It's just the media sensationalizes it and presents it as fact or proven theory. That's why you get articles saying things like: "Smelling other peoples farts could prevent cancer" :/
darkxfbi lol
No they don't. I think you're mistaking scientists for theists.
Glad your interested in Science.
But it sounds like you're trolling for comments. Since everyone that stayed awake during 8th grade science class would know what you are saying is not true.
And of course, you cant be a Christian. Since Exodus 20:16 has a nice comment about bearing false witness and we wouldn't want to sin would we?
Perhaps it is Carl Sagan trying to communicate with his fellow scientists!!. "Contact", what a wonderful science fiction movie!!
Aren't chemists trying to isolate an "island of stability" in the periodic table? Perhaps an element from this "island" has been formed in the cluster somehow?
I hope the new element, or whatever it is, will be named a 'Bulbulon', or a 'Bulbulino', or similar. Bulbul led the team that discovered it and published a paper on it first. So, it should be named after her. :D
1:27 3560 keV? He means 3560 eV (3.56 keV like the chart shows). 3560 keV would be 3.56 MeV.
I wish I had known I love universe so much back when I was younger. Now in 27 years its too late I think to study math again and get to some science which deals with anything in universe, planets, stars, galaxies, whatever. Well, at least I can wish a lot of luck to those who've found out that earlier than me. :)
This mystery may go on 100 years from now.
And it couldn't just be a new unknown element/molecule?
3,560 keV? 1:26
AMAZing discovery. Nobel prize stuff, if it leads to what dark matter really is. PS love her name "Bulbul" it's one of my favorite birds!
Its cool that can be found so far away.. but a missing plane can not be found on earth. hmm
Didn't Ting(discoverer of the Charmed quarke back in the 1970s) find evidence of dark matter by means of odd x-rays from our own galaxy also?
The evidence mounts!
Does it mean that there is a power source supplying all these galaxies and stars in the universe as mention in the Book of Job 38:19-20 and Enoch 17:3?
A red/blue shifted object imposed behind would explain it.
aliens?? lol
Hey, it could be.
aliens everywhere then lol
Maybe we should call it the "Devil" particle.
Science.nasa.gov describes this object as looking like "a cloud of gas in which each atom is a whole galaxy"...
I watching NASA because i want learn more with the space and im 10years old
pleiadians! :D
nice ... narrated by HAL3000
That Esra Bulbul is pretty sweet. Bet those scientists are just trying to get laid by suggesting its named after her. Don't blame them :P
an echo?
Dark mass effect; while dark energy and dark matter are the same in nature by conception.
Go Get Those Geckos!!
Clearly aliens. I always take the least probable possibility to win high.
Does Kryptonite ring a bell to any of you geniuses’?
WE'VE LANDED ON THE MOON!
Big Mystery in the Perseus Cluster.
Mystery Bubulon!
Here, no more than 15 kms deep, we don´t know all. There, millions of light years must be all possiblities of other materials ands rares species Congratulations, NASA
dark matter! yeah! hooray dark matter!
Everything doctrine called "dark", will never be deciphered using the funds of matter and energy, because it's something that does not belong to this entity. Who can argue that calculate how the universe has matter and dark energy and dark matter, if at all and neither does what it represents the dark. This perception of the universe is, indeed, not knowing the nature of the universe completely.
get a grip on things a little closer to home first.
eiπ + 1 = 0
Es claro la ciencia no tiene nada q ver con creencias la realidad humana seria diferente si no nos gobernaran las falacias.
God Knows
First nerd to comment.
If it were.not for God there would be no universe. No nothing. This wonderful science only proves His Greatness even more.
Thanks and Praise to You JESUS +
Constructive interference.
