We've talked plenty of times here about the infeasibility of launching a mirror big enough to directly image exoplanets using ...

When astronomers talk about an optical telescope, they often mention the size of its mirror. That's because the larger your mirror, the sharper your view of the heavens can be. It's known as resolving ...

“This three-telescope interferometry is a major milestone toward directly imaging the growth phase of supermassive black holes,” said Sebastian Hoenig, a postdoctoral researcher at the UC Santa ...

Intensity interferometry is a promising technique that enables the precise measurement of spatial properties (i.e., distances, shapes and light properties) by probing fluctuations in the intensity ...

Warming up: illustration of the interferometer. (Courtesy: APS / Alan Stonebreaker) An atom interferometer that does not have to be cooled to cryognenic temperatures has been created by physicists in ...

The ESO (European Southern Observatory) has announced the successful observation of an exoplanet using optical interferometry. It's the first time an exoplanet has been "seen" in this manner and the ...

Purdue faculty dedicate countless hours to exploring the frontiers of their respective fields, pushing the boundaries of knowledge and contributing to the ever-evolving landscape of academia. To ...

The concept of measuring surface roughness originated nearly a century ago as a means to prevent uncertainty and disputes between manufacturers and buyers. Now, it has become a common identifier used ...
