Cosmic noise, also known as galactic radio noise, is a physical phenomenon derived from outside of the Earth's atmosphere.It is not actually sound, and it can be detected through a radio receiver, which is an electronic device that receives radio waves and converts the information given by them to an audible form.
The Big Bang Observer (BBO) is a proposed successor to the Laser Interferometer Space Antenna (LISA) by the European Space Agency.The primary scientific goal is the observation of gravitational waves from the time shortly after the Big Bang, but it would also be able to detect younger sources of gravitational radiation, like binary inspirals.
Radio waves (black) reflecting off the ionosphere (red) during skywave propagation. Line altitude in this image is significantly exaggerated and not to scale. In radio communication, skywave or skip refers to the propagation of radio waves reflected or refracted back toward Earth from the ionosphere, an electrically charged layer of the upper atmosphere.
The Laser Interferometer Space Antenna (LISA) is a planned space probe to detect and accurately measure gravitational waves [2] —tiny ripples in the fabric of spacetime—from astronomical sources. [3] LISA will be the first dedicated space-based gravitational-wave observatory.
The Atmospheric Waves Experiment (AWE) is a NASA instrument to be mounted on the exterior of the International Space Station (ISS) for the study of atmospheric gravity waves (not to be confused with astrophysical gravitational waves).
In 2008, the Chinese Academy of Sciences began demonstrating the feasibility of space gravitational wave detection, proposing the "Taiji Program" for China's space gravitational wave detection, and establishing the "single satellite, dual satellite, three satellites" and "three steps" development strategy and road map； and in August 2018, the "Taiji Program" single-satellite program was ...
The European Space Agency has selected a gravitational-wave mission for its L3 mission, due to launch 2034, the current concept is the evolved Laser Interferometer Space Antenna (eLISA). [20] Also in development is the Japanese Deci-hertz Interferometer Gravitational wave Observatory (DECIGO).
The game is set on either an unnamed planet or city (depending on platform) where the player must defeat waves of invading aliens while protecting astronauts. Development was led by Eugene Jarvis, a pinball programmer at Williams; Defender was Jarvis's first video game project and drew inspiration from Space Invaders and Asteroids.
