    Hello wonderful Anton,yet another awesome video brutha,they just keep getting better&better,keep up the good work,have a great night!!!

  2. Snippy Cutwell

    It’s never aliens and that star Isn’t going to explode… real boring Universe…

  3. Chris Herb

    Studying the evolution of (different types of) stars is an important part for the understanding of our universe if not the golden key to it I’m convinced. –
    Sometimes I’m wondering if we (that are made out of elements born into our universe) are the manifestation of self awareness of this universe.
    Life here and there lighting up shortly like neurons in a huge, cold and dark brain. ๐Ÿ˜…

    I gave some random smol spider that decided to live inside my house the name of Antares. Rip i hope you are in somewhere better

  7. WalkingTheWoods

    I knew it! It’s those damn Antarans, they are up to no good!

  8. GoreQuill NachoVidal

    OMG it has an atmosphere! There is is life on that star!!!!

  9. Silas Dense

    Another fascinating subject with new findings and discoveries that are interesting to hear.
    Thanks Anton !!

  10. RobertMStahl

    Please excuse my French, but, I do not think you have your Sun calorimeter properly calibrated, from sea to shininG plasma. “Hey, let’s go into the deeper freeze of outer space and get hotter out there!” “And, again!” You do know Mills has myriad upon myriad ways to measure dark matter as well as produce dark matter. The only byproduct is oxygen but, already, I am off the subject. Bye for now. :/D

  11. keneuter valve

    You seem down today anton. Smile.

  12. Boris Be loud us

    Beetle juice Beetle juicewill be better than Antares with the super nova

  13. alertonoff 4

    ..erm .. the correct arabic phonetic pronunciation is ‘Bet-elgeurze’ .. and doesn’t it sound infinitely more sexy ..

  14. KamuiPan

    Those planets maybe dead for life now, but after the star transformation they would not be inundate with the basic elements for life? Like a second generation for life to form? If, of course it’s in the right distance. Just some random speculation.

  15. It's Not THAT Complicated

    I just looked down… and…. weโ€™re wearing the same shirt! Oh snap! Love the channel. Incredible content with amazing research/detailed information.

  16. Troy W

    See the black hole yet its on a 360ยฐ set out???? Want to know what dose the heat belt ????????? On the thermal!

  17. Roman Sapp


  18. chester clarke

    So it’s a star with weak gravity because its expanded to the point its mass is thinly distributed

  19. Matt CA

    uh, we know much of the liquid water on Earth will evaporate in the next 500 millions to 1 billion year due to increase luminosity of the Sun alone, would this new fact mean we have even less time to relocate life ?

  20. Chris Yunge

    Is there a new type of radiation producing such anomalies, but have you the tech to see…??????

  21. Giovanni Salazar

    Anton. What is your thinking of thoughts of those really massive round dark objects they cought around our sun taking plasma, or something from our sun, then they take off extremely fast.. and they are extremely huge, much larger then the earth.. have you see this???

  22. Andrew H

    Easy answer for why there is a layer of hot plasma on the surface is leaking fusion plasma over the years trapped in a natural magnetic bottle in a vacuum. Lets say each of the boiling bubbles that pop carry even just a few pounds of plasma you will have a huge amount fast in that trapped pocket.

  23. John Johansen

    This time I was early!

  24. Quinton Honeycutt

    Why do super massive red giants pictured to look so clumby and uneven surface?

  25. Jim Curtis

    Thanks for yet another great video Anton. I think I can speak for everyone here and say we all appreciate the hard work you put in to this channel. I always feel like I’ve learned something I did not know before. ๐Ÿ˜‰๐Ÿ‘

    Keep up the amazing work bro… ๐Ÿ–๏ธ๐Ÿ˜

  26. Yaldabaoth

    Imagine the Antarans living on their equivalent of Neptune’s moon, which is perfectly warm and habitable. Then they discover freaks like us who basically live in our star’s backyard.

  27. lasarith2

    Ah oh he said Corona.

  28. Scott Cole

    Anton, you kept calling Antares and Betelgeuse red giants, When they are red Supergiants…Iโ€™m sure it was an honest mistake

  29. zwartehoutentafel

    Hello wonderful Anton. This is person

  30. Skyman 58

    Just imagine UY Scuti’s cromosphere!

  31. Mark Kaidy

    Scientists keep observing more and more matter in the universe ; i.e the halos of galaxies, the distributed atoms of “empty space”, black hole matter and big chromospheres around large stars. Dark matter/energy is the very stuff we could not observe in the past and now are beginning to see….nothing exotic but very interesting indeed.

  32. AL Can


  33. No Body

    good video. Interesting. Lots of facts. very little speculation. wish all the videos were like this.

  34. El Chivo

    hello wonderful person

  35. William Taylor

    When our planet explodes its going to be great, ill be on the navigator bridge and we all pull the trigger on the count of three, everybody agree to destroy the world? High five, rebellion party. A bunch of teardrop craft from the second superforce dimension infected the planet, take that earth! They got all banged up crossing the asteroid belt. It appears the speed of light was different here and destroyed their computers. They were corroded from the ice stuck to the hull, we recovered Galileo and it was a second diety that made teardrop junk into a side warp craft for us to go and invade the second superforce dimension with our own overmind opera oblivion mentality.

  36. Jeffrey Stumpf

    Hi Anton

  37. martin burns

    the stars are powered by the galactic birkeland currents, it somewhat explains why the outer layers are so much hotter than the interior

  38. jupiter

    Oh… i had the hope of surviving… but i guess i’ll die too… F

  39. billiondollardan

    What happens to normal matter when it encounters these very high temperature atoms in very near vacuum? Say you gave a cow a spacesuit and had it way out in the far chromosphere of Antares. When the cow hits the individual atoms, would there be any significant interactions noticeable on a macro scale?

  40. pentagramprime

    America will go supernova before Antares does.

  41. Luke Skywalker

    Oh my god

  42. Patrick Parker

    Only reason why I know of Antares is because it is in Scorpio, the constellation that correlates with my birth date.

  43. Leiion Reyn

    I think that sun going to explode?

  44. James Aron

    Wonderful chromosphere

  45. j s

    did not Uhuru from star trek sing about antares?

  46. Gorbaz The Dragon

    Although ALMA and VLA operate in different frequency bands, they are very similar systems which operate on many of the same fundamental principles and a lot of systems in ALMA are closely related to those of the VLA.

  47. Mike O'Keeffe

    15th. P.S. Im craving a Danish. Edit Im hungry I forgot to put Hello Anton. Stay wonderful.

  48. George Holloway

    Would it be a threat to earth if it became a magnetar or pulsar?

    You are always so surprised, Anton.

  59. Gregg Weber

    Are those “dark” patch either terrestrial sort of material that is caught over a subduction zone?

  60. Art Science Wonder


  61. RustyCobalt

    The unexplained source of energy for the chromasphere may be explained in part by cosmic electrical currents such that are proposed by the Safire sun model (also electric universe by thunderbolts project)

  62. Itachi Uchiha

    Makes me wonder how far Antares corona extents.

  63. William Mellor

    Speak up Anton! That crackly voice drives me crazy

  64. Bob in the West

    So… more questions than answers you say?
    I bet no one saw THAT coming…

  65. Ace

    So…the “Antares Maelstrom” that Khan Noonien Singh said he’d “Chase Kirk around before he gave him up!” is actually a thing?

  66. walt7500

    I demand action!

  67. Brandon Sergent

    Have you done a video on recurrent micronova anywhere? If not, would you please?

    What if god were his own destructive radiation, so powerful that we, tho hubrisly valuable were mockery…? So let me laugh.

  73. Patrik Malnar

    and i thought this day couldn’t get any better… thanks Anton! :D

  74. Jim Carrie Fan club

    That moment when Anton says Antares will go super nova in 10,000 years but we wonโ€™t be here to witness it.

  75. Stephen Thomas

    In today’s thrilling adventure, evil genius Anton moves the red guant Antares to the centre of The Solar System and causes it to go supernova! Can all the wonderful people be saved? Find out in today’s exciting episode of What Da Math!

  77. Gregg Weber

    Back in the day when the only time you could take a picture of the outermost part of the Sun was during a Solar Eclipse there were streams going away that varied from eclipse to eclipse. Will they get so numerous that they will seem to cover most if not all of the Sun?

    11:55 If the stuff is blown away from, it is being blown to. Not to the same place at first, but into the ballpark.

  83. Edward John

    YOU are a wonderful person
    Thanks for another insightful vid ๐Ÿ‘

  84. Neurons

    When I think of Antares, I think of Master of Orion 2… classic game. A pity the most recent reboot wasn’t as good.

  85. Alpha Scorpii

    Since I am a Scorpio, Antares is my favorite star:)

  86. Pup314

    The sun doesn’t have enough mass to become a “super” giant but only a giant.

  87. John Westwood

    Ohhhhh Anton was sponsored by Coke everyone!!!!

  88. Russian Bot

    I always get what I want in ten years. I want to see that star blow

    I went back to your old videos and realized youโ€™re an IB student lol i was too. Funny thereโ€™s quite a few of us out there now

  90. TOMAS

    I want to know how your pup “YODA” is doing ??

  91. ScratchTicket Seb

    Hey Anton, I would like to see a video about Orcus the Dwarf Planet please! Thank you and good day, love ur vids!

  92. Marc C

    Antares is my favorite star. For whatever reason, it appears way more red than other red giants like betelguese or arcturus

  93. ShauntSerelu

    We love you Anton! Thanks for educting us every day :)

  94. Robert Smith

    You know, when you put things into perspective like that, i can’t imagine what it would be like to actually look at an object like that, that big and take it all in ๐Ÿ˜ฎ๐Ÿ˜ฎ๐Ÿ˜ฎ

  95. Ben DC4L

    My favorite star, the heart of the Scorpion ๐Ÿ˜‰

  96. Xanna Via

    I like your channel, I learn a lot. I do have a question can you do a video about Alfa Centauri gravitational lensing that is predicted for May 2,028? Thank you keep up the great work.

  97. Osmosis Jones

    About a planets size a being able to have an atmosphere. .with if its half’s earths size but flies into cloud behind a hot Jupiter. . or the moon of a super or medium maybe even Minny puff

  98. Guan Joe

    Same t-shirt for like 10 vids lol
