When faraway stars explode, they send out flashes of energy called gamma-ray bursts that are bright enough that telescopes back on Earth can detect them. Studying these pulses, which can also come ...
Light curve of the gamma-ray flare (bottom) and collection of quasi-simulated images of the M87 jet (top) at various scales obtained in radio and X-ray during the 2018 campaign. The instrument, the ...
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 ...
Amy Lien receives funding from the NASA Citizen Science Seed Funding Program. When faraway stars explode, they send out flashes of energy called gamma-ray bursts that are bright enough that telescopes ...
When a distant galaxy briefly outshines everything around it in high-energy light, astronomers usually know which playbook to reach for. Gamma-ray bursts tend to fall into familiar categories, either ...
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 ...
This study is led by Prof. Shaolin Xiong (Institute of High Energy Physics, Chinese Academy of Sciences) and Prof. Jirong Mao (Yunnan Observatories, Chinese Academy of Sciences) and Prof. Shuang-Nan ...
Down here at the bottom of our ocean of air, it’s easy to get complacent about the hazards our universe presents. We feel safe from the dangers of the vacuum of space, where radiation sizzles and ...
The Sun’s most violent flares are turning out to be even more extreme than I, or many solar physicists, had imagined. By tracking how these eruptions light up the high‑energy sky, researchers have ...
