Not the biggest astronomy error I have ever witnessed (that was 10 ** 200), but this one got my attention. Ha!

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.

Fascinating information, this galaxy is a very popular target in the night sky for astrophotographers.

Tackling actively accreting black holes will play havoc with your nail finish.

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.

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.

Fantastic video. I always find these very interesting. Especially the parts I actually understand. ;)

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 :-)

really pulls it together there at the end VERY COOL btw nice job on event horizon

Awesome video! Very interesting :)

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.............................................................

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.

I have to make 2nd visit, it's so sheared, smeared looking with high emissions. Very interesting to image like M63.

Wowzers!! She's sharp as a thumbtack! My brain hurts thinking about a water maser... Universal SuperSoaker.

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!

@BaronSamedi1959

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.

Very cool.

love her enthusiasm

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?

Does the gas heat up by friction, or just the pressure?

8:49 Dr. Becky's nice eye.

I hope that Dr Becky is having a good day.

22 to 25 light-years away? That can't be or we would all be toast.

Cosmologists often leave out the mega or million when talking with each other.

Had to re - ring the bell. wth YT?

Dr Becky is back :D

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?

@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?

@leftaroundabout

4 жыл бұрын

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

@9:52 oops. 22-25 LY away would put it inside the milky way.

In my universe M106 sets the fan speed.

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'.

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

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?
