small misspeaking, but large difference - M106 is not 22 to 25 lightyears away, but 22 to 25 megalightyears
You mean the mega maser quasar is mega parsecs away?
That had me confused too.
Yes, if it was 25 light years away we'd be in serious trouble!
I know astrophysicists love approximations, but this is ridiculous
Not the biggest astronomy error I have ever witnessed (that was 10 ** 200), but this one got my attention. Ha!
I love M106, thanks so much for sharing your knowledge!
Fascinating information, this galaxy is a very popular target in the night sky for astrophotographers.
You should cover the very recent discovery of a probable Seyfert event in the Milky Way about 3.2 Myr ago, by Joss Bland-Hawthorn and his team. Their analysis combines the Fermi bubbles data with the ionization of hydrogen clouds in th Magellanic stream. So we may be living in a Seyfert galaxy, which may just be a temporary condition of any galaxy. Worth your attention.
I guessat 9:50 you meant 22-25 million light years away? 25, 25 thousand and 25 billion wouldn't make sense and the number 22 to 25 is too specific for it to be something else like 2,5 or 250 something.
[EDIT] yeah, 5 second google for NGC 4258 would have told me that.
Oh my Universe - my chipped nails 🙈no one look!
I am far to interested in you being excited about space to notice your nails
Becky the gorgeous star I see that sparkles in any deep field returns. If I discover a star Becky I would name it after you
I'm already busy looking at the octocat in the background!
Your enthusiasm makes up for it!
Tackling actively accreting black holes will play havoc with your nail finish.
Fantastic video. I always find these very interesting. Especially the parts I actually understand. ;)
It's pretty crazy that lasers/masers occur in nature; they require pretty contrived situations to appear on earth, and I guess they're pretty rare in the cosmos too. Super interesting, and I really love Dr Becky's enthusiasm, pretty sure she just coined a new term ;).
I'd love an episode on the distance ladder and the different clever ways cosmologists have come up with to measure distances with little more than a few smudgy dots of light on a photographic plate.
I love all videos with Becky !
This galaxy is my favorite. Thank you for this information!
Nice piece on the Today program about Mercury vs Astrology :-)
Still have a backlog of material with Dr Becky? Sweet!
Mega Masar will be a thing from now on :-)
1:08 In this version of physics, electrons do Hohmann Transfers between energy levels. Neat.
Jebediah Kerman up to his old antics I'm sure
really pulls it together there at the end VERY COOL btw nice job on event horizon
Awesome video! Very interesting :)
I have to make 2nd visit, it's so sheared, smeared looking with high emissions. Very interesting to image like M63.
I can’t draw a straight line without a scale, but from this I learned I can draw a black hole. And a clump of Maser emission looks like a smashed spider.
Mega Maser Quasar = MEMAQ Pronounced, "me mak". Used in a sentence: "Holy cow look at that memaq emission"!
Wowzers!! She's sharp as a thumbtack! My brain hurts thinking about a water maser... Universal SuperSoaker.
thanks for the informative series of videos ...and for all the work u do @DeepSkyVideos
just a curious comment ...y does @Dr.Becky use the "normal" way to calculate distance of m106 from earth ; i thought space was curved (as mr einstein said) and there must be some pretty fancy mathematical way of calculatin distances in space ........ unless.............................................................
Very cool. I keep imagining a version of Spaceballs in some bubble universe has a mega maser.
..."Aaaaim de laaayzzaar.... FHIGHAR DE MEGAA MAAZAAHRRR!!!"
AMAZING MASAR
Really appreciate teaching skills here - good teachers take complex ideas and explain them in ways the layman can understand [sort of :-)]
Very cool.
Love the high tech laptop stand! ;)
Considering the contents of that laptop stand, describing it as "high-tech" is probably accurate. :-)
Yet another great video. Here's an idea for a video. The nebula flyby in the video got me thinking, how bright would a nebula be if you was really close? The clip on the video gave the impression it would be really bright, but how bright would say the Orion nebula be if we were say less than a light year away, or even just a few AU? I was always under the assumption that as they were so massive, the luminance per area is actually low. Would love to hear your charming explanation!
They maybe massive but are also rather big so the density will be rather low, *I think*. SO when you get quite close the brightness will be low as you will be seeing the darkness of space through the glowing gas.
@@BaronSamedi1959 That's what I think aswell. Would be nice to get the Doc's opinion on it tho!!
So are we seeing just the glowing accretion disk or are we seeing the jets pointing at us or both? also does this mean the mega maser light is highly polarized like in lasers?
love her enthusiasm
Cosmologists often leave out the mega or million when talking with each other.
Wait... she said that the distance to the Mega Masar was 25 light years. Surely that can't be correct?
Missing "millions".

8:49 Dr. Becky's nice eye.
Dr Becky is back :D
Does the gas heat up by friction, or just the pressure?
I share your love for this galaxy. I even have it tattooed on me 😊
22 to 25 light-years away? That can't be or we would all be toast.
Had to re - ring the bell. wth YT?
How is the graph made?
I hope that Dr Becky is having a good day.
That's the tidiest scientist's office I've ever seen! Where are the piles of journal extracts dating back to 1973?
Line Noise right
😂 I’m a neat freak. Also - pixels not paper!
@@DrBecky I LOVE YOU!!! Honestly your genuine wholeheartedness motivates me to be more enthusiastic when I interact with people throughout the day. Your happiness is infectious and I hope to be the same way.
New DSV, thank you!!!
Now ignitine the Mega-Maser-Quasar-Blaster,
and the world is ours!
we get the office video on a different channel?
Bradys channels are well worth watching.
I saw that galaxy it with a 10x50 binocular but it takes a very dark night.
Have any blue nugget galaxies discovered so far have massive galactic central black holes?
Does it have any satellite galaxies?
Sweet octocat mini
9:30 is the distance 20 to 25 ly??? That sounds like inside our own Galaxy. Did you mean 25 million ly? Or are we talking about the distance between that blob and the black hole?
Who says "QM says"...?, Why? What? How does it "say" outside of the Anthropic Principle? (String Theory Mathematics)
This is the next posit of harmonic resonance-> coherent interference radiation in sequence since Vera Rubin's "Dinner Plate" galaxy rotation observation. Interesting and an illustration of the Conformal Fields=> i-reflection/black-hole Modulation Mechanism of probabilities in potential possibilities QM-TIMESPACE, e-Pi-i interference Principle.
Can we just make masar an official term?
@9:52 oops. 22-25 LY away would put it inside the milky way.
Oh my frack!! My notifications are turned off for this channel and I DEFINITELY didn't have it set that way. What the eff?
you still have it in your feed so just dont sub to 20000 chans and youll be fine
Get that fixed!
@@Axonteer yeah, thanks. It's more of a "why did that happen" comment, though.
@@DeepSkyVideos you better believe I fixed it immediately!
Thanks for a reminder.
The CZcams cor-rector's do love you Dr Becky! Best regards!
Columated mega masers, yes I said to myself, that's what I was thinking .
You are my favourite...
I find the answer why discoveries are going so slow :( they are done on Mac's
Is there any life on this M106 galaxy?
That's what I've always said, things like Gamma Ray Bursters, things that blast high energy photons anisotropicly across space distantly especially are kind of naturally occurring lasers. The jets of ionized matter acreating into things like black holes form a population inversion preferentially in a particular direction or vector and through super-radiance, single pass laser gain without a fabry perot cavity, these structures preferentially blast out energy at higher than expected levels due to stimulated emission along the jet axis.
I've also wondered that if one set up an actual resonant cavity with gallium arsenide, zinc selenide or first surface gold mirrors on a suitable substrate in the atmosphere of Mars, would you get a CO2 laser beam at 10.6 microns?
We had a naturally occurring, water moderated, nuke reactor in Africa. Why not naturally occurring lasers?
Maybe not freakin' sharks with freakin' laser beams on their heads but what about Gamma Ray Bursters?
I'm not sayin' anything, just sayin'.
mega maser quasar laser phaser goes brrr
@5:46 a photon has exited an electron to go to a higher band, and then a second photon 'stimulates it down', emitting one(?) photon? What am i missing here?
You've basically got it right. The weird-seeming thing here is the “stimulating it down” part, but actually this shouldn't be too surprising: all the emission / radiation processes are reversible, so coupling to a down-transition is in principle just as well possible as to an up-transition. The reason we don't usually notice that as much is that in most situations, there are far more electrons in the low-energy state than in the high-energy one, so up-stimulation has simply much more opportunity than stimulated emission. The few instances where that does happens normally go unnoticed because the emitted radiation is indistinguishable from the stimulating one.
That's very different in a laser/maser though, the crucial thing being the population inversion: there are more electrons in the _high_ energy state, thus you actually get more energy out after the stimulation and that's the light/microwave _amplification_ mechanism.
en.wikipedia.org/wiki/Population_inversion
@@leftaroundabout Aha. Thanx. From that wikipedia page: en.wikipedia.org/wiki/File:Stimulated_Emission.svg
22-25 Mly is not ±3%. It's nearer ±8%
This is what CZcams is for
IT'S INSIDE OUR GALAXY!!! RUN AWAY!!! RUN FOR YOUR LIFE!!
"Quantum mechanics says..."
LOL
in 5:40 both photons should leave the vicinity of the atom.... the way it is now, it looks like that the stimulating photon is being absorbed, which is not right
Is the universe not FASCINATING?
In my universe M106 sets the fan speed.
Aristarchus is the singular Earthbound source to all skylights. but you are a doctor so the Earth can't be flat and stationary and all the reflected skylights can't be local reflections off of a contoured watery mirrorlike barrier. carry on.
Gaser?
Darth Vader wanted me to ask, can you put that technology on a "moon"? 😉
Could fast radio burst be the equivalent of the x Ray maser, by polar reversal of the singularity ?
Masers were invented before lasers.
Megazord
Halton Arp Seyfert Galaxy, what did he find? Seeing RED? Why would a astronomer get banned for trying to publish his observations? Science after all is questioning the Narrative even if it means you get Blacklisted! Why is that?
I love how passionate she is.
Am I the only person terrified by massive clouds in space shooting microwave lasers? What would happen if an inhabited star system passed through the beam? I imagine the distances are big enough that this scenario is very unlikely but imagine a whole planet being boiled or sterilized by a huge beam randomly sweeping through the neighbourhood...
Yeah pretty sure quasars are not habitable
Me, thinking about gamma ray bursts.

Ill bet her dotted dress was chosen because of deep sky videos and it sort of imitates the night sky ;-)
23-25 light years ^ - 3 away , so, on the page
Pesky ould critterz those interfering antiferometerz; al ways cloud prognosiable aspects in shadow like a drought oasis that was a dream within a dream? 'T was a Mirage al' de time! No joke ;
The universe is a grand menagerie, filled with animals we can barely imagine.
what if red shift measurement is wrong? Maybe the universe is not expanding.
What if the measured evidence I have of your making of this comment is wrong? Maybe you never made this comment.
Dr B trying to find D
@ 9:54 - "22 to 25 ly away" - MILLIONS!!!!!!!!!!!!! OMG, you didn't notice that when you edited the video??????
How can yous say that is a real image?
Rule #276 of The Patriarchy *clearly* states that women are not allowed to know space...things.
(no, I was not actually serious)
Wrong pronunciation of Seyfert.
You're accidentally touching an interesting issue: How does it come that maths are so incredibly good at describing our universe? Your comment of course is still totally insane of course.
does anyone else like notice the oddness of a British scientist using a manner of speech reminiscent of like, California valley girls?
Doesn't the university own a tripod 4 that camera. The filming of this made me carsick.
l u .
You know you've been single for too long when an attractive doctor talking about collimation makes you a little weak at the knees.
Allah understands our prayers even when we can’t find the words to say Them.
Beckey's dimples are just so distracting.
Solder Joe Who’s Becky? I only see dimples
rubbish
omg chipped nails i cant watch anymore, unsubbed
This is all bad science
