Gravitational wave, Venus missions get European green light

The European Space Agency gave the green light to two missions on Thursday, one to detect ripples in spacetime called gravitational waves and another to probe the secrets of Earth's closest neighboring planet Venus.

Paper explores ideal orbits for space-based interferometers

Ever since the telescope was invented in 1608, astronomers have striven for bigger and better telescopes. When it comes to instruments to observe the sky, bigger really is better whether you are observing faint galaxies or ...

LIGO surpasses the quantum limit

In 2015, the Laser Interferometer Gravitational-Wave Observatory (LIGO), made history when it made the first direct detection of gravitational waves—ripples in space and time—produced by a pair of colliding black holes.

Interferometry

Interferometry is the technique of diagnosing the properties of two or more lasers or waves by studying the pattern of interference created by their superposition. The instrument used to interfere the waves together is called an interferometer. Interferometry is an important investigative technique in the fields of astronomy, fiber optics, engineering metrology, optical metrology, oceanography, seismology, quantum mechanics, nuclear and particle physics, plasma physics, and remote sensing.
