If Earth-like planets require an extremely rare supernova encounter, then water-depleted rocky planets might be exceptional. But if cosmic-ray immersion is sufficient—and common—then the conditions ...

A new study reveals an intriguing possibility: asupernova explosion might have sent a surge of cosmic rays toward Earth around 10 million years ago, with consequences etched in ocean rocks. The ...

Rocky planets like our Earth may be far more common than previously thought, according to new research published in the journal Science Advances. It suggests that when our solar system formed, a ...

A supernova is a cataclysmic stellar death that leaves behind a black hole or neutron star. It is the biggest, brightest, and most violent type of explosion scientists have observed in the universe.

When a star explodes, it sends high-energy particles out in all directions. This burst of energy can travel through space for thousands of light-years, traversing solar systems and even galaxies. In a ...
