A NASA-funded scientist has produced a new type of picture of the Earth from space, which complements the familiar image of our “blue marble”. This new picture is the first detailed image of our ...

In the early 1930s, Swiss astronomer Fritz Zwicky observed galaxies in space moving faster than their mass should allow, prompting him to infer the presence of some invisible scaffolding—dark ...

"Maybe there are additional mechanisms generating gamma rays that go beyond the interaction of cosmic rays with the surface of the sun." When you purchase through links on our site, we may earn an ...

Researchers may have identified what could be a compelling clue in the ongoing hunt to prove the existence of dark matter. A mysterious diffuse glow of gamma rays near the center of the Milky Way has ...

Astronomers are trying to understand what caused a series of gamma ray bursts, or GRBs — the most powerful explosions in the universe. These energetic bursts are typically unleashed by the incendiary ...

Thunderstorms are far more radioactive than previously thought, routinely producing gamma rays—the highest-energy form of electromagnetic radiation typically associated with supernovas and other ...

NASA sent a retired Cold War spy plane on a storm-chasing mission, and it discovered that big thunderstorms are very radioactive. Large thunderstorms produce so much gamma radiation that the clouds ...

Above the cloud tops, thunderstorms throb with a complex, frenetic light show of high-energy radiation. A view from a retrofitted spy plane soaring at 20 kilometers up revealed storms glowing and ...

Astronomers have determined what caused the brightest cosmic explosion ever recorded. Lasting a matter of minutes, the gamma-ray burst, named GRB 221009A, was observed by astronomers in October 2022.

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. Thunderstorms create a lot of wind, rain, and lightning, but many ...

Where public-health policy is concerned, it makes sense to be conservative. But when we try too hard, we may actually do more harm than good. An egregious example is our policy on low-level ionizing ...

Nearly a century after astronomers first proposed dark matter to explain the strange motions of galaxies, scientists may finally be catching a glimpse of it. A University of Tokyo researcher analyzing ...
