“Ultramassive black holes — that is, black holes with masses exceeding 10 billion solar masses — are probably not rare; several and even dozens of these colossal black holes may exist.” -Julie Hlavacek-Larrondo
The largest black hole in the Universe was a shocker when it was first discovered. At 40 billion solar masses, it certainly is impressively large. Like other quasars and active galaxies, it has a luminous accretion disk that can be seen from a great distance. Like only a few, one of its two incredibly energetic, polar jets is pointed directly at Earth, creating a blazar, the brightest of all active galaxies.
But what makes this object, known as S5 0014+81, so special is that it got so big and massive so quickly. Its light comes to us from a time when the Universe was only 1.6 billion years old: just 12% of its current age. If this brilliant, massive object were located a mere 280 light years away, or ‘only’ 18 million times the Earth-Sun distance, it would shine as brightly as our life-giving star.
