Nothing can escape from a black hole. So where do Hawking radiation, relativistic jets, and X-ray emissions around black holes come from?

Plants at room temperature show properties we had only seen near absolute zero.
In a recent paper, biologists outlined a three-part hypothesis for how all life as we know it began.
If there are three neutrino species, all with different masses, then how is energy conserved when they oscillate from one flavor to another?
In the infant Universe, particle physics reigned supreme.
When supermassive black holes merge, they emit more energy than anything else to occur in our Universe except the Big Bang.
Two fundamentally different ways of measuring the expanding Universe disagree. What’s the root cause of this Hubble tension?
How (not) to end up in the ash heap of history.
In the quest to measure how antimatter falls, the possibility that it fell “up” provided hope for warp drive. Here’s how it all fell apart.
Although the Big Bang occurred at an instant in time long ago, we still see the light from it. Will the evidence ever disappear completely?
From how life emerged on Earth to why we dream, these unanswered questions continue to perplex scientists.
Quantum uncertainty and wave-particle duality are big features of quantum physics. But without Pauli’s rule, our Universe wouldn’t exist.
The Universe isn’t just expanding, the expansion is also accelerating. If that’s true, how will the Milky Way and Andromeda eventually merge?
Wind farms seem less productive when scientists incorporate more realistic atmospheric models into their output predictions.
From the Big Bang to dark energy, knowledge of the cosmos has sped up in the past century — but big questions linger.
In general relativity, white holes are just as mathematically plausible as black holes. Black holes are real; what about white holes?
If it weren’t for the intricate rules of quantum physics, we wouldn’t have formed neutral atoms “only” ~380,000 years after the Big Bang.
Cosmologists are largely still in the dark about the forces that drive the Universe.
NASA’s only flagship X-ray telescope ever, Chandra, still works and has no planned successor. So why does the President want to kill it?
When you combine the Uncertainty Principle with Einstein’s famous equation, you get a mind-blowing result: Particles can come from nothing.
As we pursue the leadership difference we seek, we attract fuel and generate heat. The trick is to avoid burnout.
The Big Bang’s hot glow faded away after only a few million years, leaving the Universe dark until the first stars formed. Oh, the changes!
Just by observing the tiny amount of deuterium left over from the Big Bang, we can determine that dark matter and dark energy must exist.
Just 13.8 billion years after the hot Big Bang, we can see objects up to 46.1 billion light-years away. No, this doesn’t violate relativity.
The future belongs to complexity.
Practically all of the matter we see and interact with is made of atoms, which are mostly empty space. Then why is reality so… solid?
From the explosions themselves to their unique and vibrant colors, the fireworks displays we adore require quantum physics.
The “first cause” problem may forever remain unsolved, as it doesn’t fit with the way we do science.
Since its observation discovery in the 1990s, dark energy has been one of science’s biggest mysteries. Could black holes be the cause?
You can only create or destroy matter by creating or destroying equal amounts of antimatter. So how did we become a matter-rich Universe?
