The environmental impact of electricity generation from wind power is minor when compared to that of fossil fuel power. [58] Wind turbines have some of the lowest global warming potential per unit of electricity generated: far less greenhouse gas is emitted than for the average unit of electricity, so wind power helps limit climate change. [59]
PSR J1719−1438 is a pulsar some 4,000 light-years (1,200 parsecs) away from Earth in the Serpens Cauda constellation, approximately one minute from the border with Ophiuchus. The pulsar completes more than 10,000 rotations a minute. It is approximately 12 miles (19 kilometers) across but with 1.4 solar masses. [3]
PSR J0437−4715 is a pulsar. Discovered in the Parkes 70 cm survey, [5] it remains the closest and brightest millisecond pulsar (MSP) known. The pulsar rotates about its axis 173.7 times per second and therefore completes a rotation every 5.75 milliseconds. It emits a searchlight-like radio beam that sweeps past the Earth each time it rotates.
PSR J0002+6216, also dubbed the Cannonball Pulsar, is a pulsar discovered by the Einstein@Home project in 2017. [2] It is one of the fastest moving pulsars known, and has moved 53 ly (5.0 × 10 14 km; 3.1 × 10 14 mi) away from the location of its formation supernova, where the remaining supernova nebula, CTB 1 (Abell 85 [3]), is.
Environmental assessments are routinely carried out for wind farm proposals, and potential impacts on the local environment (e.g. plants, animals, soils) are evaluated. [84] Turbine locations and operations are often modified as part of the approval process to avoid or minimise impacts on threatened species and their habitats.
X-ray pulsar-based navigation and timing (XNAV) or simply pulsar navigation is a navigation technique whereby the periodic X-ray signals emitted from pulsars are used to determine the location of a vehicle, such as a spacecraft in deep space. A vehicle using XNAV would compare received X-ray signals with a database of known pulsar frequencies ...
A pulsar–neutron star system, e.g, PSR B1913+16. A pulsar and a normal star; e.g, PSR J0045−7319, a system that is composed of a pulsar and main-sequence B star. Theoretically, a pulsar-black hole system is possible and would be of enormous scientific interest but no such system has yet been identified.
Pulse generators are also used to drive devices such as switches, lasers and optical components, modulators, intensifiers, and resistive loads. The output of a pulse generator may also be used as the modulation signal for a signal generator. Non-electronic applications include those in material science, medical, physics, and chemistry.
