Visit science.nasa.gov/ for more. 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.
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.
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.
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?
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.
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 ... www.thunderbolts.info/faq/quasineutral.htm
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.
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?
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
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. :)
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" :/
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?
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.
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?
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
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.
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 +
