How can you escape from a black hole?

Typically particles approaching black holes are captured in a matter of milliseconds, but a small fraction may have a chance to escape. This is suggested by the latest observations from the Integral satellite of the European Space Agency (ESA) , with which particles have been detected a millisecond before being trapped .

Now astronomers have discovered that this chaotic region is crossed by a complex network of magnetic fields , which have a complex structure in the form of tunnels through which some particles manage to escape from the gravitational well . For the first time, the presence of these gravitational fields has been identified so close to a black hole.

A team led by Philippe Laurent, a researcher at the CEA (Commissariat à l'atomique énergie) in Saclay (France), made the discovery by studying the s i binary stema of Cygnus X-1, where the gravity of the black hole is dismembering Star accompanying it. The results suggest that this magnetic field is strong enough to pull particles out of the gravitational well and pump them out, projecting a jet of matter into the vacuum of space. The particles that make up these jets gain speed through spiral paths , which affects a property of radiation known as polarization.

These are the most Earth-like exoplanets

Among the more than 5,000 exoplanets discovered to date, these are some of the most similar in size, mass, temperature or star to the one they orbit.
