    They say it is space dust in the way of the galactic center? Can't they just observe the radio waves like the other one?

    Not sure why but I've known for years that they "can't see" the whole milky way because of position. Although I have not read the details about this black whole and its galaxy- it's probably "easy to see" because of it's position...easier to point telescopes at. While they would need to leave the milky way and travel some ridiculous number of light years to get a view in its entirety with the black whole.
    I don't really think dust is relevant for the kind "pics" they took?

    And if you think about it- in terms of the scale of the universe, when trying to depict massive objects in their entirety, distance may actually be your friend.

    I see what you mean. Accordingly to the model we're in a position in one of the arms of the milky way and can't see the whole galaxy. From the CGI visuals I've seen it looks like a bright cloud when looking to the center.

    Radio waves should go through space dust to observe the galactic center, then again it's like 50 thousand light years away.

    If you think about it, they had to find a black hole that is in the correct position for the telescopes. I'm assuming most of the telescopes are stationary. So to form one big telescope that points in exactly "one direction" may have been more dependent of object's position( that happened to be the one). There are many black holes, but this may have been the perfect one for the telescopes. I'm just taking guesses btw.

    I have really no clue at all how they did it. So they can pretty much come up with anything. That's why space is the magicans dream theatre. A dark infinitly deep hat he can pull out whatever he wants. But I think that's how they say they did it. Multiple dishes collected data.

    The nearest "black hole" is the one that supposedly exists in the center of the Milky Way, a so-called "supermassive blackhole." Supposedly it's big, it's massive, it gobbles up stars for dinner-- so why isn't their a pic of it? Or some kind of indication that the center of the Milky Way is a giant whirlpool into Dimension X?

    It's also an easier target rather than a random-ass "black hole" supposedly 53 million light-years away from Earth? NASA can take a pixelated picture of some "black hole" in another "galaxy" but it can't take a picture of the "supermassive blackhole" in the center of the Milky Way.

    Hahaha.
    The M87 black hole is actually bigger than our Sagitarius A* black hole. Also, it's a lot clearer to see. Sagitarius A* is smaller in size and is surrounded by a lot of gas and matter that makes it harder to see from Earth's perspective. The team is working on getting a photo of Sagitarius A* it's the time scale for the project's completion is currently unknown.

    In relation to our black hole -why would size be the reason they aren't able to produce a pic of Sag. M87 is like 55 million LIGHT years away. Size would probably matter in comparison to similar black holes in the universe. If Sag was as big M87 we def wouldn't be able to see it with today's technology.
