Congratulations for 25 years of great work. Here's to another 25!

[@charleslaurice]

I’m 70 years old now days and live in deep poverty area in the southern Philippines. Thank you for playing your part in making the world a better place,you are so very kind natured and love to listen to you on the edge of my seat. God bless you young man 👍

[@revmsj]

Awesome!

[@RichardClark13]

Congratulations on doing what you do so well for 25 years. Good to go for another 25.

When I visited Australia from the US we went to a dark sky location to see the milky way (MINDBLOWING), but I was pointing out Orion to my GF and suddenly realised it was upside down, really blew my mind realising that, finally converted me from a flat earther (only kidding) but just rocked my world seeing that, may not sound amazing but seeing it IRL and realising my position on the planet was giving me this new perspective really put things in, err, perspective.

[@chrisendacott8765]

And your Upside-down to me is the only way I've ever seen it. Hope to be in the north one day to experience it the other way too.

[@realzachfluke1]

Happy 25th, Fraser. I hope I'm able to find that same kind of spark for myself one day, and I'm so glad you did. My life without Universe Today would've taken a totally different course, and I'm convinced it would've been a worse course, because that's just the quality of content we're talking about here. Here's to many more 🎈📡🔭

[@thebogsofmordor7356]

Congratulations on a quarter century Fraser & universe today team! You know the old saying "Bulls of a horn flock together!"

[@itsmodsiw]

Congratulations for the 25 years of devotion. You're amazing.

[@markfrancis5164]

You are hilarious today Mr Universe. The equatorial crescent Moon will now always be a ‘The Balls of a horn’ moon. I spat my cuppa tea across the kitchen table and laughed so hard. Thank you, you made my day !

[@moremindsbetter]

Huge congrats on the anniversary Fraser. Universe Today is amazing - thanks to you and the entire team for the entertainment and learning I get here

[@josephmcphee9143]

[@gary3808]

Vendiker, 25 yrs of space journalism is amazing. Congratulations!

[@runrin_]

Risa was my fav this week. Congrats on 25 years Fraser. Having Universe Today remain relevant through all the changes in how people learn and consume information is a true feat.

[@kyoteecasey]

Gratz on 25 years Fraser! Love your work mate

[@Roguescienceguy]

Congrats Fraser And thank you to you and your team for all that you do

[@ilessthan3bees]

Happy anniversary! Universe today (and all you do) is a big part of why I love space. Here's to 25 more!

[@aurtisanminer2827]

0:32. Congrats!! I was 14 when you started. Glad you went this direction and stuck with it!

[@FrancisFjordCupola]

Congrats on the 25th birthday Universe Today!

[@brettclarke8892]

Happy Anniversary. I like your channel.

[@NovaDeb]

Congratulations on your 25th anniversary of starting Universe Today. Today's episode is one of your very best for teaching us fundamental concepts. I learned so much. Thanks.😊

[@revmsj]

This was a great week! 👍🏾

[@Nowherenear-w1d]

Congrats with such a significant anniversary. That was great, we liked it

[@markmcdougal1199]

Congratulations, Fraser. Great job, thanks for all the excellent reporting.

[@universemaps]

Happy 25 years of Universe Today, Fraser! 🎉

[@RoxasXaviar]

Little late to saying this but congrats on 25 years. Your content is stellar glad I found you earlier this year.

[@Severe_CDO_Sufferer]

There it is... (at 25:42) right in the middle. (right where it belongs) 👉 it's a Plasmoid. 👈 and it's always "right in the middle." (of stars, galaxies, and perhaps even atoms)

[@booradley4237]

Congrats! My child is 25 years old... and so is yours

[@camsy83]

'Bulls of a horn' passed through my brain as an entirely normal phrase, and it's only when you corrected yourself that I realised 😂

[@frjoethesecond]

Andoria. Great question and great answer.

[@thorstenkrug144]

YAY !!! So good. May the next 25 years bring us all more awesome news. ❤Keep on rocking and break for nobody. 😊

[@TheAces1979]

Congratulations on a quarter century of excellence! Cheers mate!

[@ruphind8376]

Wow congratulations 🎉 I’ve been watching you for over 23 yrs

[@Aetoski]

Congrats! You're the best out there!!

[@tonywells6990]

[Andoria] Best answer of the week.

[@12345.......]

Southern hemisphere stargazing is on my bucket list

[@isitme1234]

Best videos on youtube by far.

[@bobhillier921]

Thank you for 25 years

[@markfrancis5164]

Congratulations Fraser on your 25th anniversary! Wow, what an achievement! Fantastic! I began listening to you on the early iTunes podcast around 2002 I think. It’s when you did a weekly audio show with a lady astronomer and I remember I had over 200 episodes on my titanium Mac laptop- and I still have it on life support?!

[@Dan-Simms]

Cait was the best question, cool to learn about your history and congratulations on 25 years since the website!

[@AubriGryphon]

During the 2012 Tulum cruise, I remember you mentioning the moon being in a different orientation because we were so far south and I was like, "Uh, I guess? A little?" Then I realized you were speaking mainly to people who didn't already live around 30N and the difference was much more significant to you. XD

[@JohnSostrom]

When you were talking about what you can see in the southern hemisphere you left out the Great Southern Cross. The first time I saw it I was stationed on a US Guided Missile Frigate on our way to Australia. The size is amazing. I loved going out on the weather deck after midnight out at sea and watching the sky. Particularly in the Pacific Ocean, hundreds of miles from any land. On a clear calm night there is nothing like it❤❤❤

[@benjaminbeard3736]

Ansonia: really good question! Great answer. Super detailed and thorough , as usual.

[@coulie27]

I've often wondered about moon moons myself 😅

[@NullCreativityMusic]

Moon-Moon

[@parthhappy]

Great videos. I am now a regular consumer :) you are so knowledgeable and yet so humble. Huge respect for you ! Keep up the good work.

[@mrxmry3264]

10:48 when a white dwarf exceeds the chandrasekhar limit, shouldn't it collapse into a neutron star instead of exploding? 22:39 now why does that thing remind me of the eagles in space 1999? 36:11 also, don't forget that the universe was much smaller and therefore much denser than it is today. that's gotta have some kind of effect.

[@tonywells6990]

A type 1A white dwarf supernova has a carbon-oxygen core, not a dense iron core, so when it goes supernova its entire core is blown apart and does not undergo core collapse into a neutron star.

[@topquark22]

Thank you Fraser for answering our questions, from stupid laypeople, in an understandable manner. Your pedagogy is exceptional.

[@jaygarricktheflash]

Congrats on the amazing accomplishment

[@richardreumerman5449]

Congrats on your 25 year anniversary!

[@DarlinDarable]

Congrats on your anniversary!

[@rayg5146]

You should do an anniversary show with the most exciting events over the past 25 years

[@bbbenj]

Thanks a lot 👍

[@gwenever7286]

Congratulations on your sites Silver Jubilee!

[@Chris.Davies]

22:15 - any Mars cyclor would be artificially kept in the Earthy moon system longer than the single loop-back pass. This is because in order for a space station to be useful, it's gotta carry a lot of stuff. And so you stick it in an Earth-Moon figure 8 while you load it up for the Mars leg. Because there is no moon to orbit at Mars, everything gets dropped at once , and the station heads back to earth. I like the idea for freight, because it's very efficient. But it is also very slow, and so putting people on board would be a Bad Idea.

[@eamonia]

I love the way my wife snores. It's so cute. Cute little snore. ❤️

[@loft82]

Hi Frasier, love your channel 😊 Question: would the universe be colder if there had been no stars, galaxy's ect. .?? Congrats on your 25 years ...

[@marvinmauldin4361]

The orientation of the crescent Moon changes even when you stay in the same place. There is a folk tale that drought is caused when the Moon "holds water," that is, looks like a bowl held horizontally. When the Moon bowl is tipped so the water can flow out, the rain will come.

[@JayKay-d5p]

Congratulations

[@dontcare397]

thank you for your awesome show Frasier

[@araucaj7]

Congratulations 🎉❤,🙌

[@recterbert]

Congratulations Frasier! Been listening to you since Astronomy Cast when the iPod mini first come out lol.

[@austinsapp5867]

Risa! Such a cool concept

[@pewterhacker]

Another great KZbin channel is Graviton Media.

[@nardocallanta3039]

Happy 25th! Wooooh Hoooh!

[@hoppyrabbit1833]

Is there any chance you could snag Nobel laureate George Smoot for an interview, especially for his work on COBE? Your interviews are outstanding! Congrats on 25 years!

[@DeannaGilbert616]

One of the highlights of a trip to Buenos Aires for me was seeing Alpha Centauri for the first time. I didn't even realize at first I was looking at it, until I saw a bright star, and then saw Crux and realized where I was looking. Ironically enough a few months before that I'd gone to Hawaii for the first time and it was pretty cool to see so much of Scorpio.

[@laurachapple6795]

From Ushaia, Argentina, I got to see the moon looking fully upside-down. I knew it would do that but it was still very weird to see.

[@EngineeringAllAround]

Thank you!

[@DanBennett]

Congrats on the 25th anniversary!

[@Severe_CDO_Sufferer]

at 11:37 What if Halton Arp was right about what causes a redshift in light? (what if light is not analogous to sound) Has anyone made a map of the distribution of stars and galaxies, where redshift is a function of the age of an objest, rather than distance?

[@jeremyeharris]

Cait! Thanks for sharing your astronomy origin story :)

[@crowlsyong]

Happy 25th anniversary!

[@sergey9986]

Regarding Laniakea, we have a perfect reference frame - CMB. Our movement in relation to it is measured quite precisely. Without this correction, all measurements of the Hubble constant do not make sense.

[@savetheplantet5799]

Congrats man!!!

[@BrokenhornKT]

ConGrats on 25 years!! Wow time fly's Fast and thank you for all your Great information.

[@MistSoalar]

Aeturen. Never traveled to the other hemisphere, but never thought of it. Totally makes sense.

[@Dop3Dawg]

Congratulations Fraser! Here's to 25 more years👍

[@ninatolfersheimer]

I heared from people like Dr. Becky that we don't really know how the supermassive black holes at the centres of galaxies formed. What's the deal with this? Could you talk about black hole formation for a bit?

[@pi1392]

Wow the show is the same age as me. Well done Fraser ❤

[@steveriese8338]

Remus. Great program!

[@elviscera4661]

Aeturen One can never have too many flat-earth counter arguments.

[@koleoidea]

I've heard that all of the hydrogen in the universe was formed during the big bang. What sort of energies would be needed to synthesize a proton? Have there been any papers or ideas on how this might theoretically be done?

[@isitme1234]

25 years??? Wow congratulations!!

[@Greeniykyk]

Omega Centauri can be seen from the northern hemisphere in May and June. I saw it from The San Luis Valley in southern Colorado around 38 degrees north. A dark unobstructed southern horizon (no clouds, trees, hills, mountains) is necessary.

[@aizquier]

25 turns around the Sun!!!!! Congratulations!!!!

[@Severe_CDO_Sufferer]

at 23:54 Have you ever heard of the Structured Atom Model? (aka: SAM)

[@RectalRooter]

Vendikar The StarTrek documentary series shows just how we drop subspace beacons all over the place for this purpose.

[@culture-nature-mobility7867]

I'm a big fan of the Plonk-satellite!

[@onebylandtwoifbysearunifby5475]

Planck satellite gave us amazing Universe information. We need more science satellites and fewer bombs.
