The "cosmic pinwheel" that astronomers feared could one day shower Earth with lethal gamma rays may not be as dangerous as ...

A new study explains how thunderstorm electric fields produce strong gamma‐ray glows with oscillating gamma‐ray rates, and that these oscillations develop into intense pulse trains that closely ...

The U.S. Naval Research Laboratory (NRL), in partnership with NASA's Marshall Space Flight Center (MSFC), has developed ...

New research led by W. M. Keck Observatory Instrument Scientist and astronomer Grant Hill has confirmed what scientists have long suspected—WR 104 comprises two massive stars: a Wolf-Rayet star and an ...

“Peat soils have a unique ability to block this type of naturally occurring radiation, drastically reducing the number of ...

A new study has shed light on the orbital alignment of the well-known Wolf-Rayet 104 (WR 104) system, long considered a potential threat due to its speculated gamma-ray burst (GRB) risk. Observations ...

The same result is obtained when studying the pulse-height from the gamma-rays emitted by different substances. There is, in this case, a continuous distribution of pulses from zero to a certain ...

An artist’s concept of the famous Wolf-Rayet 104 “pinwheel star,” previously nicknamed the “Death Star.” New research ...

Decades of W.M. Keck Observatory research on the famed Wolf-Rayet 104 “pinwheel star” system has taken a new turn, revealing more mystery but reducing concerns about its potential as the “Death Star.” ...

Researchers at University of Galway have created a new approach to finding peat soil, giving insight to where carbon is ...
