F. Parker, I am so glad to see you back. You are the best up to date source for news on Tabbys star I have. Made my day to wake up and see you here!☺😎 Thanks for all the work you do, Glen
The spectrum of the dimming event is highly indicative of a dust cloud. A contiguous solid structure would show a dimming across a wider range of the spectrum. A dust cloud is going to block some wave-lengths better than others depending on the average size of the particles.
Very interesting. I always check here to see the latest happenings with Tabby's Star. It will be interesting it the James Webb Space Telescope can see anything new with this star.
stefan r , No. If the fluctuations are due to the alien activity, it's plausible that the active construction of a Dyson sphere/swarm could have a similar light absorption profile as dust. Construction sites are messy places, after all. I really hope it's not aliens. Oh God, please not aliens.
Mickytdi, Dyson sphere has not been ruled out for Vega (alpha lyrae). Vega looks like it has a Kardeshev 1.8 civilization. Could also be a much smaller civilization that pollutes a lot and/or suffers from Kessler syndrome. It is possible there is no civilization there. No one knows what is going on around KIC 8462852. Vega is 50 times closer (25ly vs 1250ly) and was the first star ever photographed.
Hey, there seems to be some issue while donating using a card in where is the flux page (possibly because I'm not in US?). Can you please check that if possible.
Astronomers publish papers. A media circus is not really helpful. People the astronomers consider colleagues and serious student candidates for an astronomy program will all be comfortable reading publications in astrophysical journals. The major observatories have each others phone numbers and can call to say "hey take a look at this, sending attachment in e-mail". They do not need a utube audience in the loop. Not much of the public is interested in graphs.
John Michael Stock i dont see Dr tabitha mention long term dimming or much about the sudden brightening event. Last i heard was a paper they published saying it was dust. Then nothing else.
Because everyone was working on the kilonova event? I think they set a record on how many pages (triple digits) were needed for listing authors, before the actual short article.
I wonder if the inhabitants of that star system tried to do something to the star to reverse the downward trend. The effort may have caused a very short term recovery cycle, only to fall through the floor. If this isn't the case, it still makes a good basis for a sci-fi story.
Bill Cape, The science fiction version people want is a Dyson Sphere construction. The star is a perfectly normal (except with aliens) type F3V star. We see a dimming because the light goes into solar farms instead of traveling here. The sad version is that there was a construct that caused the 20% dimming events seen by Kepler. That broke up and now we are seeing dust. Other sci-fi includes starlifting. People deliberately shrink and dim stars.
iok-1, That might depend on how they go about it. Any of the orbital structures would cause dimming. Also the gas and dust that gets lifted could dim a lot. In this Hubble image of ll pegasi www.spacetelescope.org/images/potw1020a/ all of the star's visible light is blocked. For stars that are spinning it depends on the angle you are looking from. Vega's (alpha lyra) pole is brighter and bluer than the equator. It would take a long time to change the star's spin. The flairs seen on Proxima Centuari or UV ceti are much brighter in x-ray.
So a long term project would account for the long term dimming at a continuous rate and the short brightenings and dips would be caused by excesses of dust that they stir up. This began hundreds of years before 800 CE. I wonder if it's still going on.
It's fun to speculate about this being a feature of some kind of advanced technology at work. Less fun is to speculate about all the possible natural causes. Here's an idea: Maybe two large planets collided recently in this system...
Hmm, I hope whoever made this graph has her/his statistics knowledge in order. I mean, claiming the downward trend is EXACTLY as it was before based on a mathematical function that approximates these average values in some granularity is pretty shady. If one chose a higher order polynomial for that approximation that statement would fall apart pretty quickly. Also your statement at the end about extraterrestrial intelligence is pretty uncalled for imo. Just because we don't know the cause yet does not mean it's aliens. That's like not understanding thunder and saying it is god. ETI is the last resort in this question.
lz factz "further investigation" talking about big words, huh? You don't know me. I have a background in mathematics and computer science. and you have? An edgy way to spell "facts"?
Iz factz I can hardly believe I am wasting my lunch break with you, but I suggest you check your mood in the future before writing anything on the internet, especially if you are about to call people trolls without any substantial facts to back that claim. Apart from that, the scientific method only works if scientific work holds against scrutiny. I do not say the authors of the presented paper did their statistics wrong; after all I have not read the paper. I just pointed out something that struck me as odd as we are talking about measurements with a high variance and some claims made in this video seem to me to be pretty bold considered the nature of the underlying data. I don't know if you engage in reading scientific papers regularly, but there are many out there whose claims are based on flawed statistical methods, at least in my field. The presented graph was published at the same day this video went up and seems to have been made by a single person, so I feel right in the position to ask whether the claims made about the data have been approved by other scientists in the field, and possibly against other measurements of the light coming from Tabby's star. So, Iz factz, if you want to engage with me in a scientific discussion about the topic and tackle any of the remarks I made, you are more than welcome. But I won't accept to be called a troll by someone who knows me from looking at the totally unrelated videos I uploaded four years ago.
DagarCoh, Aliens may be the last resort if you want to publish in Astrophysical Journal. In UA-cam comments section you need present a clear model that is much more believable. Aliens is the default . If you argue that the aliens are not in one place you need to explain were they went and what prevents colonization. It is like walking into a church and declaring that lightening can not exist because the sun is shining.
Aliens is not the default. The default is "We don't know (yet)". That's like saying that until the Higgs Boson was found, the default was that god made the list of particles with a flaw because he/she liked it that way. And I don't know which videos you watch, but I have seen good, rational discussions in comment sections that did not jump the gun. This is my first video of Mr Parker though, I don't know if this is a common trend here. And I could hardly care less tbh. Lastly, for your points about what I would need to explain: if you infer aliens around Tabby's Star, you would have an equal load of stuff to explain. For both views there can only be hypotheses, but I reserve myself to scepticism when it comes to "higher power" explanations such as god or aliens.
Iz factz Sadly I cannot read your last comment fully, maybe because you deleted it shortly after posting? So I can only comment on the first sentence: How many universities DO you know that check youtube channels of students before giving them their degree? To use your words (just spellchecked): Go troll elsewhere.
F. Parker, I am so glad to see you back. You are the best up to date source for news on Tabbys star I have. Made my day to wake up and see you here!☺😎 Thanks for all the work you do, Glen
My eyes brighten up when I see your update. Thanks a bunch!
Thank you very much for the update! I jumped on this one first thing when I saw it.
That parallelogram really spooked me
Tabby also said today that the current dip is at roughly 4% right now, the deepest one seen since 2013.
they have totally new data. I think fredrick made is video a day early,
Keep up the good work. We look forward to your updates.
It's amazing to me how similar the graph is now to what it was when I started watching here
The spectrum of the dimming event is highly indicative of a dust cloud. A contiguous solid structure would show a dimming across a wider range of the spectrum. A dust cloud is going to block some wave-lengths better than others depending on the average size of the particles.
except for the lack of IR
Very interesting. I always check here to see the latest happenings with Tabby's Star. It will be interesting it the James Webb Space Telescope can see anything new with this star.
Am very skeptical about the whole alien thing, but will admit this is getting spooky.
David Dirré-Moire Would be spooky if there was no sign of ETI.
stefan r , No. If the fluctuations are due to the alien activity, it's plausible that the active construction of a Dyson sphere/swarm could have a similar light absorption profile as dust. Construction sites are messy places, after all. I really hope it's not aliens. Oh God, please not aliens.
Dyson sphere has been ruled out! Unfortunately
David Dirré-Moire, I meant galaxy wide. Would be spooky if everyone was dead. Seeing signs of life suggests there is a way to survive.
Mickytdi, Dyson sphere has not been ruled out for Vega (alpha lyrae). Vega looks like it has a Kardeshev 1.8 civilization. Could also be a much smaller civilization that pollutes a lot and/or suffers from Kessler syndrome. It is possible there is no civilization there. No one knows what is going on around KIC 8462852.

Im curious why this isnt bigger news. Why arent more astronomers talking about this?
Who says that isn't happening?

John Dlugosz, The kilonova discovery was a different set of instruments.
4 % dimming in 2 years! What would happen if our sun dimmed this way ?
4% less light would reach KIC8462852 in 1,252 years.
I wonder if the inhabitants of that star system tried to do something to the star to reverse the downward trend. The effort may have caused a very short term recovery cycle, only to fall through the floor. If this isn't the case, it still makes a good basis for a sci-fi story.

That broke up and now we are seeing dust. Other sci-fi includes starlifting. People deliberately shrink and dim stars.
Would starlifting cause dimming or brightening over the short term?

In this Hubble image of ll pegasi www.spacetelescope.org/images/potw1020a/ all of the star's visible light is blocked. For stars that are spinning it depends on the angle you are looking from.

Why are Aliens being in this video a lot of dreaming here!? It has been ruled out it can’t be extraterrestial a few months ago.
Mickytdi, Who makes this rule?
Hmm, I hope whoever made this graph has her/his statistics knowledge in order. I mean, claiming the downward trend is EXACTLY as it was before based on a mathematical function that approximates these average values in some granularity is pretty shady.

Its probably Alien.
who cares....we wont ever be able to get to it so just forget about it,move on
Narrow mind detected. We can learn about the nature of the universe by analyzing that data.
