    At 4:28 and 5:42, you can very briefly see the ‘extra stuff’ is mostly located in a very thin disc around the center of the galaxy.

  2. Richard Weeden

    I wish I was born a few million years in the future, when Andromeda shines as bright as the moon in the sky, What an awesome sight that would be.
    Edit: probably billions rather than millions

  3. vivec the not false god

    Wow, that’s big.

  4. Piotr

    Simeis 147 nebula is few Moons wide, like really huge :)

  5. Peter Toth

    How would this newly discovered halo of baryonic matter effect gravity, and the question of “dark matter” existance?

    I’m just here for the algorithm

  12. Gondolin

    1:24 BTW: Rio de Janeiro showing in the southeast of Brazil right there, the city where i come from. It’s pretty illuminated seeing it from space, wow! Sao Paulo even more.

  13. Dr. Otto

  17. 정윤교

    do you live in seoul?
    I live in seoul.

  18. RacingMachine

    Please do a video on the Urantia Book Master Universe Model!

  19. ErikJ Reddington

    What does this mean for dark matter? Is there enough matter there now around so the spinning speeds are possible?

  20. MC's Creations

    Really interesting!!! 😃

  21. Ben Heald

    I very much appreciate your efforts to provide us with science news! Keep it up, my friend!

  22. Kenny from Philly

    You are the best! Also, I now dream of kissing you, Anton! Cheers, Kenny from Philly

  23. Yankee Jim

    Interesting, good stuff, thanks!

  24. Tamás Gulyás

    imagine the view from those starsystems :)

  25. Silas Dense

    Really interesting findings.
    Thanks Anton.

  26. Alfred Sutton

    Wonderful report you wonderful person.

  27. Niklas Starow

    “We are going to build a wall against this foreign galaxy and the Andromedans will pay for it.”

  28. Michael Angelos

    That’s what she said.

  29. daniel aguayo

    The internet is fine, how many light years does it take a toaster to recieve 1 bit of info

  30. Chris J

    What a great channel. And Anton is wonderful.

  31. Omni Versal

    I thought it was 3.75 billion light years away. Either time flies really fast or there’s been some improvements with the meseurment.

    (that’s what she said)

  32. Junior Ranklin

    Incredible… makes me wonder how big our milkyway galaxy truely is? How big is our halo?

  33. kevin mcdonald

    Got to love those hotel internet connections lol

  34. M3me_EAter YT

    For you war robots players, yeah that’s what it means. Halo/Corona but what about Glory?

  35. Turbo Wizard

    I hope you’re doing well Anton, we really appreciate all of the content, but if you need to take some time for yourself, please do! <3

  36. JC DFFOO

    I read an article recently that said the halo around Andromeda Galaxy stretches about 1.3 million LY and its already touching our own Milky Way halo! Incredible!

  37. Carlos Ramirez

    See I’m not number one woohoo. 😂

  38. Brian Betron

    Nice Job! Thanks for bringing this to our attention.

  39. Denis Tyrant

    What’s scary is that the halo that points 1.3 million light years away from the Andromeda is only half way to our galaxy. So that means that the other half of the halo is likely 1.3 million light years. So it’s very likely our halo could be the same size which I believe the study mentioned.

  40. John White

    I hope you find a great place to live soon!

  41. HylanderSB

    Need an ultraviolet image of the Andromeda Galaxy? Hubble gotchu!

  42. OoMetaLHearToO

    Hey wonderful Anton. Are you still looking for a name on the channel? It just came to me one of your catch phrases that you use often… “In Other Words”. I like the sound of this quiet a lot actually. Just throwing ideas if you also like :)

  43. Thomas Dunn

    Is it because it is traveling towards us at an alarmingly quick pace?

  44. Dan Ramos

    Oh man… I still remember what it was like to download a 1-bit RLE encoded picture on a 300 baud modem off the gopher network back in the late 80s/early 90s. You shouldn’t complain. ;)

  45. Antaxtic II

    in conclusion, andromeda is a 3-c THICCC

  46. Allen Russell

    Where I live I can only see Andromeda with the naked eye of I don’t look directly at it. 🤔

  47. Edward Evans

  49. Random Being

    My favorite galaxy compared to other Samsung galaxy …

    Finally my wait is over of how andromeda’s measure, tnx Anton !
    Sorry im bad in english …

  50. donny mcgahan

    Ty for the videos, friend!

  51. Nick Lehman

    Wheres the “what da math” theme song?

  52. Swamp Voodoo Wizard

    Is it only gravity or more energy being exchanged as electricity, heat, radiation?

  53. H D

    You think Andromeda galaxy is big then you find out about the Virgo Supercluster…

  54. jack barnes

    Thanks for these vids Anton. You make these complicated astronomical wonders far more accessible to us laymen.

  55. goookklleb uhh

    Hi Anton! I hope you’re doing well and got your situation sorted. Much love from California

  56. Evangelos Araouzos

    best channel to watch after i just came home from work!

  57. jragomaster25

    Thats so weird cause i was just taking pics of Adromeda the other night!

  58. Bony's Miniature's

    wow that luvoir telescope could see into the windows of alien houses to see what they eating , i mean how big is it jesus

  59. Two Tone

    Needs a name change to the Borg Galaxy, because we are going to be assimilated!

  60. Mod Nation

    Imagine Anton finishing up his science class and he tells his students, “Thank you for listening and sign up for the science fair if you still haven’t, share this with someone who loves learning about space and sciences, maybe come back tomorrow to learn something else”.

  61. Dan JK

    I like to wave back at Anton 😄

  62. Squirrel ASMR

    Wow that halo is massive! Plus andromeda is already massive. Thank you for sharing!

  63. bang your head

    I thought the internet in South Korea was light years ahead of everyone else. What city are you in?

  64. Coady Donovan

    I’m unable to express my excitement for the future of science!

  65. Trill Mixin

    a halo? by the ringss

  66. 4.669

    I was just looking at Andromeda through my scope last night, always incredible every time I observe it!

  67. Raymond Castillo

    Even through these hard times, I’m sure your passion will lead you to great things man. Keep it up. Ill be watching.

  68. Yael Dragwyla

    “Lovoir” is pronounced “Lo-VWAH.” The second syllable is pronounced the way it is in French. :-)

  69. Patrick

    No sir, YOU are pretty cool!

  70. Ellie Beats

    There must be someone else looking at us from the galaxy….

  71. What's Next?

    You’re the best Anton, so glad you’re back! 😍
    It’s amazing how little we know about our nearest spiral galaxy

  72. Johnny Guillotine

    Much love wonderful Anton

  73. Howtard

    Well I, for one am in support of getting rid of that pesky atmosphere. Our night skies could be so much prettier!

  74. Space Ghost

    lensing…..woooo! wacky stuff like this is why im here Petrov +suspicious herb noises+

  75. joey15151

    Being able to step away from the insanity filling up our collective information streams gives some much needed respite. Thank you for keeping up with the scientific insight that feels so grounding in times like these.

  76. Osmosis Jones

    Could be anyone in the Andromeda looking back at our galaxy or is to much ration

  77. Joseph Grant

    Makes me think that Milky Way is similar.

  78. KittoO

    I remember when you made a video around 6-8 months ago or so that scientists were reporting based on dark matter found its actually Milky way that can be as much as twice the massive than Andromeda

    Lol scientists never gets tired of trolling us

  79. Logic Plague

    “What is Halo, anyway?”

    Halo is a weapon!

  80. Henry Warwick

    Imagine you live on a planet around a sun midway between Milky Way and Andromeda. Then you figure out Andromeda is heading toward you and will sweep you up as it collides with Milky way. But in the mean time, you have a fabulous view of two great galaxies. Awesome.

  81. DemoGorgonZola

    11:33 90s Internet via modem flashback, ouch…

  82. Galen Thurber

    Halo wonderful person

  83. Korpsaw

    Welcome to what ‘da math

  84. Nicholaa Dunham

    Night used to be a lot more beautiful to Egyptians. Huge purple halos. And parts of the milky way. No wonder egyptians believed in gods back then

  85. Adymn Sani

    glad I waited for the outro, enjoy your coffee

  86. The Bendu Order

    *Does it mean that some of us may already have a couple of atoms from the Andromeda Galaxy?*

  87. Shadowdeamon91

    Second….. lol

    We love you wonderful anton!

  88. Randy Sullivan

    Do we need to wear a mask for the Andromeda Strain?

  89. MeanGreen

    So the collision has officially begun. We are touching tips.
    I’m not sure how I feel about that.

  90. Winston Smith

    Halo, wonderful person.

  91. Eric Upchurch

    Noah Hawley – Enterprise-G
    Gene Roddenberry – Andromeda TV Series

  92. Cknmonster R

    Andromeda galaxy’s halo. Hello wonderful persons

  93. Luke Sonsorius

    Its funny, I haven’t watched you content since like 2016. I am very happy to see that your channel and great content is still has cool as I remember.

  94. Tara Fojtasek

    I read about this about a month or so ago.. but I was waiting to see if he would bring it up. Yayy

  95. Dwight Alexander

    I already know to not get my hopes up on the luvoir space telescope, after getting disappointed by the jwst so many times

  96. Antony Stringfellow

    That bit at the end was funny!
    A lot of people will miss that by closing the vid when the music starts.

  97. DeathsHead Knight

    maybe all this extra matter is part of or related to galactic filaments

  98. Scott Humphreys

    ‘If everything goes well’ sounds weird in 2020.

  99. Manny Irrizarri

    I never miss to watch your daily uploads.. I don’t always agree with everything you post, but I always learn something new from your channel. I can see how passionate you are about science specially about our unknown and always more mysterious universe. And congratulations on hitting 600k subs, can’t wait to see you hit the 1 million mark. Your steady growth will get you there soon wonderful person Anton.
