11:48 SOFIA is a joint DLR (Germany's space agency) and NASA project (cf. plane markings). Specifically, DLR is responsible for the SOFIA telescope which was made in Germany, while NASA operates the Boeing 747SP aircraft. So let's not only credit NASA all the time.
@berlindude75, you, sir, are correct. As a Floridian and a lover of NASA, I'm glad to see international teams work together with the very hard engineering and science of space exploration. đ
Thanks for the correction đ

NASA is a satanic scam.

How gullible are you.
Ahh, time stamps. How satisfying
Although shouldn't there be a 'Bloopers' one, or are we dangling those as a treat at the end that people shouldn't be able to easily skip to ?
@@AthAthanasius bloopers are normally at the end of the video anyways
Onalenna Sehume
Yeah, but how close to the end?
@@ragnkja jeez man I don't know lol. Normally the last few seconds of the video
Ditto!
Yes! Please include short vids of the people who write those papers you talk about. So exciting!
Thanks for the Timestamps and Chapters in the description! đ
@28.xx YES Doc, yes! Not only is getting astro-science news from a science literate 'reporter' like you SO much more valuable than the broken telephone you get from a "normal" science article written for the layman's consumption. But its more accurate in general since its not:
A) written by someone who will summarize the science in such a way as to misinterpret the findings.
OR
B) When the EDITOR get their grubby hands on the article and (RE)WRITE the headlines to be clickbait so as to outright (intentionally or otherwise) misinform the public!
C) We get to hear you converse with pros directly involved with the science in question!
Kudos to you and your contribution into making the world more science literate!
Love the retro NASA worm logo t-shirt!
21:00 I vote we call it the "Smethurst Cluster" for obvious reasons.
@@nousernamejoshua1556 What are you talking about? I'm talking about the galaxy cluster she is mentioning here. "Smethurst" is Dr. Becky's surname.
Watching this letâs me know, if I watch your older videos, lets me understand your newer ones.
Thank you.
Love your posts.
My school astronomy club is going to have so much fun when we go stargazing with our telescopes in June!! Thanks Dr. Beckyđ€
Southern Hemisphere:) but we should still be able to see a few planets
Great photos/visual aids thanks!!!
"It's chucking it down here." You're a hoot.
Thanks for this nice video; its nice to get "the news" from somebody that knows what she is talking about, and get it understandeble. Thank you for the (hard) work you put in it every time. Keep up the good work. Greetings from Belgium.
Dr. Becky, you've got the best astronomy/astrophysics/cosmology show ever, imo.
Thanks for all the hard work!
And the SuperMassive podcast too :)
Thank you Dr Becky. You make astronomy very easy to understand.
The coolest astrophysicist ever! Love the quirky references too lol
From the bottom of my heart, thank you so much for making these videos
Wow, just found your channel and love it!.....Dont get to close to them black holes :D
I always love to see scientists excited about their work, and it was cool that you had been office-mates.
P.S. It's so nice knowing other people remember Doug!
Thanks a bunch. Beautifully explained. đ«đœđ«
I'm really excited to hear what we see from the period of re-ionisation. Holding out for it being NOTHING like we expect
Awesome!!! I enjoy Night Sky News so much... BTW, 20:34 "first place" or "first plaze"? đ
Hey awsome vid got lost quite a bit but I'm fascinated by it all. Love the way u deliver ur commentary. P.s keep the hair x
Another great upload Becks. Thank you. Always appreciated..... đ
Thanks for watching :)
i love you becky !!!
what a great time we have here
Me: " A new Dr. Becky!...Oh, 30 minutes, I don't have time now. ... Wait, time stamps, I can break it up... ... ... ... Well, that was a worthwhile half hour!"
Thanks Dr. Becky, always riveting videos.
My thoughts exactly!
Is it possible to add a timestamp for the blooper section? Thanks for adding these, it's very helpful! đđ
No -- that's your reward for watching the entire video!
Love this Dr. Becky! and love the shelving in your living room! :)
Thank's for the informations....I will see it all
Dr. Becky I purchased your book on Kindle in the USA and thoroughly enjoyed it. My only complain is that it was too short :). Congratulations!!
Thanks for making this video.
That was really cool. Thanks for that.
Dr. Becky, you're a wonderful science communicator doing a lovely job of demystifying astronomy and letting us see your enthusiasm for this fascinating field. You should feel good :)
Live in South Wales U.K. Just bought a 150 m/m Skywatcher brand reflector telescope. This content will help me study the sky. Thank you so much, space is just amazing.
Thank you Dr.Becky for making such an excellent video with your smiling full explained.Hopefully,for the future hard works too.
Another great video! Just received my copy of Space at the Speed of Light. A wonderful text for anyone! Thanks enjoying reading this afternoon. After watching the video you have just created. đ
@nomlomomlo Her book just published here in the US
Nice Timestampwork there, really helpfull!
She makes this Incredibly fun, her way of explaining everything is a complete pleasure to listen to and watch.
That's a lot of cool news!
Supernova poop, very interesting concept for the formation of new stars.
The image behind you in the thumbnail is intriguing. Reminds me of Van Gogh Starry Night!
9:00 "The More You Know"
Dr Becky you might not know of those NBC PSAs from the 90s but that graphic instantly reminded me of that.
Great episode đ
Splendid video. Well done.
First things first. Oh so amazing! Thanks I try to let the little ones get this. Take care blessings to you and yours. So nessarry and important.
It's the first time I ever heard the expression, "Toenail moon"! It's so perfectly descriptive!
the part with the intervening matter was realy smart. i liked it very much. maybe you can give more of it.
She said, "The Toenail Moon is pared ... with Venus." And for a moment my brain had this wonderful image of the old goddess doing her toilette. I love the way Dr. Becky brings the cosmos to life.
I can't wait for JWST. That's probably going to be the most nerve wracking launch that I'll see in a long time.
Love your vids,ordered your book. So stoked!
Great episode. I too love the interviews. We will take em when you can get em! Got the book! Hope to have time to read it soon. P.S. I think the long hair is cute.
Great Video!
Very informative....I like her...Thanks
I like how excited she gets when she wants to teach us astrophysics
Such an official sounding horn at the beginning! Lol good video as always
Great video đ
Saw your toenail moon this morning on the way to work! :)
Maybe a video about black holes and how the different properties they exhibit might be a good topic. Much of the talk about BH's is about a special case of a non-rotating BH, whereas, it would appear that most (?) are rotating, and that means they have different properties (i.e. related to the "No Hair theorem). Might clear up some misconceptions?
Made my dayđđŒđđŒ
Woohoo! Always look forward to these.
Getting time on the new telescope would be a massive privilege. Hereâs hoping you get some. đ€đ»
Always nice to put a face to a name.
P.S. your hair didnât interrupt the mic at all. Also, itâs not long. Itâs just right. It could be longer actually. đđ»đ. His name is Doug.. đ
A good comparative reference for the distance between baryons that are one meter apart, would be that the next closest person to you is approximately 3 times the distance from here to Pluto (making vague approximations) đč
@becky Is gravitational red shift observed in black holes?
If yes then how?
I think I can handle watching an awesome 30 min video.
Can you do a video about why our sun is so calm compared to other g type main sequence stars.
Did you speed it up when editing? It looks like it's playing at like 1.125
I think it's depth. Either new lighting or camera. The dimensional depth is much better, not as flat so seemingly more layers or higher Processing by cmos or just a much better light.
I have no idea.
Really cool to see the scientist behind the paper!
Amazing videođđđ
I'm a bioinformatician and would like to hear you talk about some of the statistical methods you use. I learn a lot by listening to particle physics experimentalists, and other disciplines talk about the way they approach their statistical methods.
Bioinformatician, never ran across one. I'm a bio-engineer, but mostly worked in the aerospace/defense field. Could of used a combination like your a few times in life support/zero G botany/bacteriology. Statistics didn't quite cover some growth rates that caught the specialists by surprise.Probably could have used somebody like you then, late 80s to early 90s.
All you need to know is space is not what you have been told and the only thing any so called space agency sent to space was your imagination đđ€Ł
@@ger8956 Are you a flat earther?
Is a farbok like a springbok but further away?
Would it have to be an actual particle 1 per cubic meter? Or could some of this be virtual particles that on average resolve to approximately the same mass as one particle per meter? Just thinking?
Great video! Minor critique/typo. At 19:45, the image caption says: "Hubble Space Telescope as seen from the International Space Station". Hubble orbits at 340 miles while ISS is around 250 miles, therefore I doubt that this caption is accurate. I think that view is probably from the shuttle.
Great observation!
If the objects orbiting are essentially falling laterally, could the ISS be looking "up" and still have a circular frame in reference?
I think you're right though.
How about, Does the sun arc across the sky or the stars move?
I was thinking maybe the earth has a dual axis spin, denoting the sun and the moon's arc. But they are not the same arc as the night time just like our solar system is not in the same plane as the MIlyway , right? Still not sure of a dual axis but certainly the stars didn't move.
According to photos of galaxies they seem to settle on whatever plane. đ€·ââïžđ
I don't know how to thank you for all the informationsđđđ
fully support the faces behind the papers idea! đ go for it Becky đȘ
Was watching Djuma cam in south africa (here on youtube) a few days back and a sliver Cresent Moon from south africa looked like a Full moon in the early morning as the Earth shined on the Moons dark side in the east an hr before sunrise ... with a Venus accompaniment... was amazing ...
What is the radius of the accretion disk compared to our solar system, the sun, the black hole itself?
(thumbed up) sun diagram "not to scale" lol ... I'd like an added momentary slide showing actual scale for "mind blow moment" and subtle education to adjust trajectory of the world's minds toward science
Hi Becky. Can you tell me what the difference is between Magnetism and Electro-Magnetism? Thanks................
Can magnetic fields that strong influence or even override gravitational influence at the distanced between stars?
excelent video as ever dear Rebecca
Does our distance to the sun have any effect on temperature at all? After all, the southern hemisphere has its summer when the Earth is closest to the sun, and summer temperatures do seem to be generally higher than in the northern hemisphere summers.
I am always amazed at what can be measured and detected these days, it is just cool. I also wonder how the magnetic field around the black hole is generated, presumably it is the accretion disc?
Ooh a new video!
21:03 Call it Cluster McClusterface.
Clustery McClusterface
Just looking at the coordinate designation, j0416.1-2403, and using alphanumeric replacement, I get joaig i zaoe, which kind of sounds, to me, like "joey zöe," which is a cute name. So I'm calling it the Joey Zöe Cluster in my head from now on.
How do people become a GTO for a telescope? I loved this video! đđ
They apply with a specific project in mind ahead of time - they get picked and JWST makes that one of their main science goals
Feels like I started circling a black hole sometime back in March. A day has passed for me since then, but 3 months have passed here on Earth! đ
i love the way you say "doust"
Doug reference?? I'm in love...
I would call it Brian. Yes, Brian is an excellent name for a Galaxy cluster. Thanks for another brilliant episode.
Still anxiously waiting for the JWST .. just don't know how long the anxious wait will go on :)
It's so funny because the amateur astrophotography community loves the dust lanes because it gives texture and a sense of depth.
Dr Becky, can we have some news about the new eRosita x-ray images please! (Spektr-RG)
Wow! Timestamps.........great.
I had a quick search on web why Xrays etc don't red shift to visible light, or do they?
I love your material and you explain this subject so well. Can you get a star named tmlong2?
those polarization movements... raving betty of yore coming through?
Dr. Becky I have a question about M dwarf stars. I know they are old, small and a little lower mass than the sun. My question is an M-dwarf star normally stable or does it become chaotic in closer periods or longer periods? Not sure I asked correctly so there it is. Thank you..
Supernova poop! What a great description...
Yayyy new vid đđ
I wish infrared. LWIR, N-band 8-12ÎŒm would be observable from the ground. There is an atmospheric window that should have similar transmission rates to visible light.
Sadly my cameras and lenses get absolutely zero signal. But it's possible to see the moon, and I have seen a paper of people observing the moon with a 2M scope and a OTS camera similar to the one I have.
I knew the JWST would be the answer when I first heard about the paper. You need a lot of light gathering capability deep into the infrared because of the extreme redshift. JWST!
Can you please tell me from where you read this all scientific(specifically astronomical) research papers bcoz I'm really interested ?
and yaa PLZZ PLZZZZ REPLY...
