Astronomers are baffled by EP240408a, a rare cosmic explosion that defies explanation, sparking theories of a black hole and ...

In this series, we cover provocative questions in astronomy. This week: the mysterious extragalactic signals known as Fast ...

The Space Coast set a new record in 2024 with 93 launches from all providers, building off the 72 orbital missions flown in 2023. With SpaceX’s continued pace, more launches from United Launch ...

Fast radio bursts (FRBs) are one of the greater mysteries facing astronomers today, rivaled only by gravitational waves (GWs) and gamma-ray bursts (GRBs). Originally discovered in 2007 by American ...

About 13 billion light-years away there is a supermassive black hole actively sending out a spectacular beam of energy directly towards Earth. Interestingly, this isn't just any black hole; it's a ' ...

Radiation within the visible spectrum can appear black if it is low in power – more specifically, lower in power than its ...

Optics and photonics covers the entire electromagnetic spectrum from high-energy gamma rays and X-rays ... to long-wavelength microwave and radio waves. A distinctive multivalent-effect ...

With February’s winter nights regularly dropping below freezing, it’s tempting to take the easy way out and just stay inside.

Shorter wavelength energy includes ultraviolet, X-ray and gamma radiation, while longer wavelength energy includes infrared and radio waves. Color perception is also affected by the quantity of ...

There were no detections in the X- and gamma-ray regimes – likely because the electron acceleration wasn't high enough – but the Submillimeter Array caught a flare of radio waves lagging around 10 ...
