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 only see it coming out of one pole. How does it decide which pole?
I googled it. Both jets exist. The jet that’s pointed away from you is harder to see, because the light particles are literally moving away from you.
It comes out both sides. The photographer was just too lazy to walk over a bit so you can see.
