Further evidence for quark-matter cores in massive neutron stars

Neutron-star cores contain matter at the highest densities reached in our present-day universe, with as much as two solar masses of matter compressed inside a sphere of 25 km in diameter. These astrophysical objects can indeed ...

What happens if you put a black hole into the sun?

In a hypothetical scenario, small, primordial black holes could be captured by newly forming stars. An international team, led by researchers at the Max Planck Institute for Astrophysics, has now modeled the evolution of ...

Permafrost: A ticking time bomb beneath our feet

Nearly a quarter of the Earth's land surface is permanently frozen. These areas, known as permafrost, are found in northern polar regions and at high altitudes. But the permafrost is now starting to thaw—with potentially ...

What have the stars done for humankind?

Professor Roberto Trotta from Imperial College London's Department of Physics is a theoretical physicist by training and astrophysicist by trade. His work explores how statistics and machine learning can help us turn complex ...

Could there be a black hole inside the sun?

It's a classic tale of apocalyptic fiction. The sun, our precious source of heat and light, collapses into a black hole. Or perhaps a stray black hole comes along and swallows it up. The End is Nigh! If a stellar-mass black ...
