A new infrared photodiode, developed using Germanium, offers a 35% increase in responsivity at a 1.55 µm wavelength, which is widely used in telecommunications. Unlike traditional Indium Gallium Arsenide sensors, this Germanium-based photodiode achieves exceptional performance in infrared light detection, making it a promising solution for various applications, including self-driving vehicles, virtual reality, and telecommunications.

The number of sunrises seen by the crew aboard the International Space Station (ISS) is determined by the station’s rapid orbiting of Earth. As of January 1, 2025, U.S. astronaut Sunita Williams, currently stationed on the ISS, is set to witness 16 sunrises as the world enters the New Year.
Williams, the commander of the “Expedition 72” mission, is joined by her fellow flight engineers: Alexey Ovchini

India is gearing up to launch a massive American communications satellite that will enable phone calls using direct connectivity from space. This innovative approach to satellite telephony is a first for India, which has previously only launched small satellites made by American entities.
The satellite, operated by AST SpaceMobile, a Texas-based company, will allow users to make voice calls u
