The European Space Agency’s Euclid space telescope has discovered 31 of the most ancient quasars ever found. Two of these giant and dazzling galaxy cores, powered by gargantuan black holes, are the earliest quasars yet observed in cosmic history. They shone with the light of a trillion Suns back when the Universe was 670 million years old – just 5% of its current age.

I love listening to the recorded black holes and quasars. Does anyone know where you can find more? I've only found a few short ones on YouTube and here:

    What is the ray of light perpendicular to the plane of the disc?

    Jets of material, a byproduct of the accretion disk and the black hole at the center:

    A good analogy might be water swirling down a toilet. Or a hurricane, viewed from above. As gas swirls in, it heats up/"speeds" up so much that some of it tends to get flung out at the poles of the disk very quickly.

    The actual physics of how that happens are unintuitive in like a hundred different ways, though, as the conditions are ridiculously extreme. It's very hot, the density of stuff varies wildly, there's a lot of radiation and electromagnetic interaction; it doesn't really resemble anything on Earth.

    Energy builds up to a point where it can’t be contained, then blows out it through the poles — I guess.

    I only see it coming out of one pole. How does it decide which pole?

    TIL Euclid is still alive. Thank you, science vampire!

    Good thing we can see the entire universe and have thoroughly surveyed all of it so this type of headline is reasonable.
