    Short of Rebuilding from scratch. What can they realistically do?

  3. Hidden Marty

    It’s not how you pronounce that name XD

  4. paul charlesworth

    Noooooo we loved you arecibo RIP

  5. Antonio Pizzolato Troia

    I posted the news some days ago, Arecibo decommissioned 💔 such an icon 😢🥺🥺 I know that is structural falling apart but we should start a petition for, at least, save some parts of the main structure for tourism or archeoscience trip. Save Arecibo. 🥺

  6. Liberty4Ever

    Coming Soon! The Arecibo Skate Park. Dude!!!

  7. The Pickle

    This is a real shame, maybe soon we could build an even bigger one on the moon.
    I remember the excitement of seeing Arecibo on an X-Files episode called ‘Little Green Men’ way back in the early 90’s.

  8. Cole Dedhand

    So long and thanks for all the fish..

  9. Michael

    Sad to see it go

  10. Mireillie Montalvo

    A preventable loss

  11. 黃屍


  12. Priapos93

    We need Arecibo 2.0

  13. Alexander Stollznow

    Looking at the general state of repair, it doesn’t appear hard to understand what happened!
    Something rusted, and broke.

  14. Ranibow Sprimkle

    I know what its first transmission is, but I wonder what is its last.

  15. Anon archist

    How do I say goodbye to what we had?
    The good times that made us laugh
    Outweigh the bad

    I thought we’d get to see forever
    But forever’s gone away
    It’s so hard to say goodbye to yesterday

    I don’t know where this road
    Is going to lead
    All I know is where we’ve been
    And what we’ve been through

    And if we get to see tomorrow
    I hope it’s worth all the wait
    It’s hard to say goodbye to yesterday

    And I’ll take with me the memories
    To be my sunshine after the rain
    It’s so hard to say goodbye to yesterday

    And I’ll take with me the memories
    To be my sunshine after the rain
    It’s so hard to say goodbye to yesterday

  16. NyceBryce

    Off topic, but you are such a wonderful person Anton. =]

  17. skaruts

    Who needs real science and engineering. Hyperloops and solar roadways, that’s the future worth dumping millions in!

  18. Webtrauma

    Nooooooo :(

  19. j stanton Good

    The Polish name is pronounced like English Volsh-chan

  20. Zoe Shur

    The shutdown officially marks the beginning of Idiocracy as we know it.

  21. Delannoy

  22. Sebastian K

    Polish names are indeed difficult :)

  23. SSS🌙

    Where’s Elon? He could fix it.

  24. Bintang Aslama

    I was introduced to Arecibo when i was a child. It was shown in Nat-Geo space documentary that i forgot what the title is. Since then I took astronomy as my main interest. Without it I won’t be who i am.

    Thank you Arecibo and Anton for making this video

  25. Mykowser

    What did you do to Arecibo you wonderful person?

  26. rxibot

    Thank you for your service.

  37. clay c

    Wait… Arecibo is in Battlefield 4! I never realized!

  38. Aaron Greenfield

    One does not simply tear down Boromir’s resting place.

  39. Gerrie

  45. Dman557

    It does need to go through

  46. Rob Goodsight

    Perfect…really a good news. 😶
    Humanity had a good tool and has been let to rot.

  47. Kakashi ReadingLog

    Anton buT got tight when talking about aliens 👽 I can tell he didn’t want to say more but really less because he’s nah believer

    Sorry bru we aren’t the smartest beings in the universe.

  48. Gregg Weber

    4:15 How large are the side lobes? Can that signal be heard by someone closer?

  49. ForOrAgainstUs

    I like the idea of someone standing at a podium, announcing to a crowd of reporters that “we’ve sent a binary encoded message to another star system, hopefully aliens are on the receiving end, hopefully peaceful aliens, possibly not a good idea now that I think about it.”

  50. Uriels Machine

    Thanks wonderful Anton, a great tribute to Arecibo.

  51. Army Nation

    It will be sad for it to go. Thank you for sharing Anton.

  52. Ahmed Syed

    Let’s start gofundme for the replacement of this telescope.

  53. Mike Johnson

    Maybe no more funding because new technologies will be declassified.

  54. Starlings murmuration

    TWEET THIS at Elon Tusk or Bezos they will buy it off lol

  55. Steve Hacker

    I’m still trying to find out what the wonderful music is at the end of your videos… Thanks!

  56. Rockin BoBokkin

    I saw Anton in the comments for a Zefrank video and this made me smile.

  57. Helvet 666

    Hey, I’ll move down there to repair it. Dying by telescope seems like a pretty cool way to go

  58. Nerd3Ddotcom

    Sigh 2020 … it just keeps giving.

  59. Carl Guderian

    well done, excellent eulogy – farewell Aricebo

  60. Greg Murphy


  61. necroorcen

  64. onradioactivewaves

    Glad you’re doing well Anton. Your channel is amazing🙏

  65. Bevin Z

    It’s almost as if we lost a great member of the human species.

  66. 8infinite8monkey8

    Pop culture fact: arecibo featured heavily in James bond golden eye. Amongst others.

  67. Thomas George Castleberry

    Anton is amazing, thank you sharing, this was fantastic.

  68. Dok Nomis

    Remake it, new tech, new materials, new construction techniques from 50 years ago.

  69. Donavan B LoForte RPN, RC

    And what would you do with 8 million dollars in Puerto Rico

  70. Fred Kost

    What keeps a fast spinning pulsar from flying apart?

  71. 11 BRAVO 10

    Went there with my daughter. It was a very visitor friendly and a grand sight up close. What a heartbreak.

  72. leon hunter


  73. Robert Trotter

    “only had military-application to begin with…”
    !WONDERFUL! …!?!…
    Thank you as always for the post of the subject Anton.

  74. 沁水灣

    Every good thing comes to an end. Arecibo served us well. RIP

  75. ruy monroe

    Hi. I live in Puerto Rico amd the news said that is out of service while doing reaparings so they say that “will continue at service after” we are not sure of it. pardon my writing i am better in spanish.

  76. Nunya Bidniz

    Anytime I hear “Arecibo,” I think of the episode of _Connections_ that featured it [which was the 1st time I learned of it.]

  77. jt wee

    well poo… i’d heard about that first cable snapping, but not the 2nd…

  78. Rob E.

    Thank you and Dave Jones for covering this. This is bad news but I believe good things can still come from this.

  79. Angel Figueroa

    I used to take my kids there. It’s was hit very hard by the hurricane Maria too. RIP😪

  80. Omni Versal

    Thank you! Wonderful Anton ✨

  81. Real Dixon

    I have been there it was amazing. :-(.

  82. Ryan Rauber

    Thanks for the memories even though they *were so great!

  83. J Haywood

    I say rebuild it!!! Get funding from some one other than the Gov’t… Other big telescopes are being built… why doesn’t a billionaire step up and form an endowment fund for it?

  84. Vampirerockstar

    006 is finally defeated

  85. Ana Trejos

    You will only see it in the movie “CONTACT”

  86. Morbo Guano

    😕😢😫😰 such a loss. Not only a magnificent instrument but a land mark.

  87. Rsmith415

    Hello wonderful people

    R.I.P Arecibo

  88. Killkor

    I’ve seen it countless times in Discovery Science astronomy documentaries, as a kid.
    And now it’s a thing of the past.

  89. IsaQuest

    I got to go there once as a kid. I lived at PR back then. I’ve always wanted to go back, but I guess I can’t anymore. RIP

  90. Demir Cruz

    Im puertorican, I live here in Arroyo, Puerto Rico, and all I can say is Thank you Mr. Petrov. I swear, I will build a new Observatory here in my Island, and it will be the Greatest, and it will be named with a name you like. Thank you again 👍🇵🇷👌.

  91. belstar

    Fail more budget cuts more money for politicians less for science and regular people.

  92. Smeif Chapman

    battlefield 4. destroying the cables was the best shit ever. then sniping from the top with the 50 cal

  93. JRR31984

    Someone needs to do something else there in Puerto Rico.

  94. Crosis of Borg

    OMG that’s where the majority of my Seti@home data packs come from.

  95. Killjester

    Greetings from Puerto Rico.

  96. RVM451

    I hadn’t heard. Now I’m sad.

  97. The Exoplanets Channel

    We will miss Arecibo a lot!!

    I hope we finish building the *1 kilometer SKA radiotelescope* soon.

  98. Perpetual Punster

    It should have been listed as a UNESCO World Heritage Site.

  99. Cact-us Brix

    That’s what happens when my wonderful island is ruled by incompetent people. Stealing the $ and not fixing the problem. We all puertoricans agree with that
