Is this a moaning skull, aflame with Halloween madness?
Actually, it's something far
scarier: a gigantic black hole gobbling down matter and spewing out vast amounts of high-energy radiation.
In the heart of the Perseus cluster of galaxies lies the monster Perseus A, a huge galaxy that is blasting out X-rays. In this image
by the orbiting Chandra X-ray Observatory, the galaxy is between the two "eyes", which are most likely gigantic bubbles of gas expanding away from the supermassive black hole at the heart of the galaxy. Those dark regions are each half the size of our own Milky Way galaxy, 100,000 light years across! Image credit: NASA, IoA, A.
