In astronomy, an interferometer can be used to [{Blank}]. What is the parallax of a star that is 15.0 light years away? Answer in arcseconds. How does the Sun's diameter compare with the distance between Earth and the Sun? How does the sun's diameter compare...
What is a Galvanometer? What is electric flux? What is the electric flux? What is thermal power plant? What is the PNP transistor? What is the resistance of a 1500 W space heater? What are superconductors? What is an interferometer?
An example is gravitational waves, or ripples in space-time that come from interactions between black holes. This was first predicted by Albert Einstein at the turn of the last century, when he showed that time and space are linked; time speeds up or slows down when space is distorted. As...
The Einstein Cross, aquasarin thePegasus constellation,according to the European Space Agency(ESA), and is an excellent example of gravitational lensing. The quasar is seen as it was about 11 billion years ago; thegalaxythat it sits behind is about 10 times closer to Earth. Because the two ...
In this study, the authors used theAtacama Large Millimeter/submillimeter Array(ALMA) to better look at 16 Psyche. ALMA is a radio telescope composed of 66 high-precision antennae. The separate antennae operate together as an interferometer with a high resolution. ALMA operates at wavelengths sensi...
In a simple example of optical interferometry, an astronomer may choose to take measurements of the same point source, like a star, with two telescopes. Each telescope collects light from the star and feeds it to an interferometer, which combines the information. The astronomer can take note of...
For now, the new object will remain a mystery. Future facilities will have more power and sensitivity. The Australian SKA itself is just one piece of the eventual Square Kilometer Array, an international radio interferometer that will be comprised of thousands of dishes around the world. It ...
Using the Laser Interferometer Gravitational-Wave Observatory (LIGO), physicists have been able to observe the gravitational waves emitted when two neutron stars circle one another and then collide. These powerful mergers might be responsible for making many of the precious metals we have on Earth, ...
Another example of an interferometer is theVery Large Telescopeat the Paranal Observatory in Chile. It has four 8.2-meter (27-foot) mirrors and four movable 1.8 meter (5.9-foot) auxiliary telescopes. It did the first image of an extrasolar planet and also saw the afterglow of the furthest ...
What is Light in astronomy? What is mean by gravitational intensity? What is dark energy? What are radiant waves? What is an interferometer? What is meant by scattering of light? What is meant by electric field intensity? What are the types of luminescence? Explain clearly. ...
