The Brightest, Most Energetic Explosions In The Universe Aren’t From Where We Thought

Astronomers have tracked a mysterious, super-bright beam of light to a hidden explosion in deep space 1.1 billion light-years from Earth. This distant explosion, presumably caused by the collision of two ultra-dense neutron starscould upend scientists’ understanding of how the brightest, most energetic light in the universe is created. In five new studies published on …

We Finally Know How Black Holes Produce the Brightest Light in the Universe

We Finally Know How Black Holes Produce the Brightest Light in the Universe

For something that emits no light that we can detect, black holes love to blanket themselves in radiation. In fact, some of the brightest light in the Universe comes from supermassive black holes. Well, not really black holes themselves; it is the material that surrounds them as they actively suck up large amounts of matter …

How huge galactic black holes become the brightest objects in the universe

How huge galactic black holes become the brightest objects in the universe

Some black holes release enormous, extremely bright jets of high-energy particles into space – yes, black holes, the epitome of darkness, cause some of the brightest lights in space. Specifically, some gigantic black holes around which most galaxies are built. While many of these galactic black holes are relatively docile, like the one at the …
