Astronomers have uncovered a new extreme in the universe's catalog of violent phenomena — a class of cosmic explosions so powerful that they rank among the most energetic events since the Big Bang.

Cosmic “touchdown airbursts” — explosions of comets or asteroids above Earth’s surface — may be far more common and destructive than previously thought, according to new research. Unlike ...

NASA’s Chandra Observatory reveals a 25-year time-lapse of Kepler’s Supernova Remnant. Glowing debris expands at different ...

The most extreme fireworks in the universe are supposed to follow rules. Gamma-ray bursts, the brightest explosions known, are neatly sorted into categories, each tied to a familiar kind of cosmic ...

Scientists reveal how two unstable nuclei trigger neutron star explosions and power intense X-ray bursts across the universe.

The vast emptiness of space is growing emptier one star at a time. That's because 80 billion lightyears from Earth, three cosmic beasts are devouring stars ten times the size of the sun. Stream Los ...

Astronomers have long struggled to capture the true nature of stellar nova explosions. However, thanks to cutting-edge ...

My research focuses on supernova explosions, cosmic-ray acceleration, and nuclear processes in astrophysical environments. By combining models of high-energy astrophysics with planetary science, I ...

Artist's rendition of GRB 250702B's ultra-relativistic jet (moving at nearly the speed of light) escaping from its dusty, massive host galaxy. Astronomers at the University of North Carolina at Chapel ...

Cosmic explosions of various kinds are a common occurrence in our Universe. In fact, such events, ranging from exploding stars to black holes, are some of the driving forces of reality. And an ...
