An underwater observatory recently detected a startlingly energetic cosmic neutrino. One possible cause involves a phenomenon ...

A blazing supermassive black hole can influence far more than its own galaxy. Scientists found that quasars emit radiation strong enough to shut down star formation in nearby galaxies millions of ...

What kind of physics is happening inside a black hole? Scientists have a lot of ideas, but taking any concrete measurements is borderline impossible—that is, unless you want to be spaghettified or ...

In 1916, only a year after Albert Einstein had published his general theory of relativity, Karl Schwarzschild used mathematical calculations to show this: If sufficient mass could be placed into an ...

Scientists have traced a 3,000-light-year-long cosmic jet streaming out from the first black hole ever imaged to its likely source point with the help of "significantly enhanced coverage" from the ...

Some things in cosmology may simply be unknowable. Why is there something rather than nothing? What lies outside the universe? What is inside a black hole? That last one has been niggling at ...
