A massive burst of gamma rays produced by the explosion of a star almost two billion light-years away was so powerful that it changed Earth’s atmosphere, according to scientists. Gamma rays are ...
The "needle in the haystack" discovery of a powerful explosion from a mysterious unknown object outside our galaxy has ...
On March 15, 2024, a space-based observatory detected bursts of low-energy X-rays from deep in the ancient universe, ...
"The gamma-ray burst traveled through intergalactic space at the speed of light for eleven billion years, during which time the Sun and the planets were born." — Timothy Ferris, in the film ...

Brightest gamma-ray burst of all time leads to both questions and answers, U of U researchers saysSALT LAKE CITY (ABC4) — Approximately a year and a half ago, a massive star collapsed and exploded 2 billion light-years away from Earth creating the brightest gamma-ray burst ever recorded ...
The powerful burst was also traced to an unprecedented 130,000 light-years from its associated galaxy’s center, where few other stars exist. Fast radio bursts, strong pulses of energy detected ...
A huge detector in the Mediterranean Sea spotted the most energetic neutrino from space to date. The particle could shed light on the universe’s most extreme phenomena.
The highly energetic explosion was initially attributed to a burst of gamma rays emitted either by the collision of two neutron stars or from the death of a massive star. Soon, however, the ...
Astronomers call such X-rays "soft," even though they are still far more energetic than visible or ultraviolet light. The burst lasted for more than 17 minutes and fluctuated in brightness before ...
The burst lasted just 2.5 milliseconds and carried the same brightness of other fast radio bursts. But it was notable because the light released by the burst was highly polarized, meaning that the ...
