For more than 400 years, astronomers both professional and amateur have taken a special interest in observing Mira stars, a class of variable red giants famous for pulsations that last for 80-1,000 ...

An international research team led by Dr. Cui Lang from the Xinjiang Astronomical Observatory of the Chinese Academy of Sciences has imaged the compact weak radio emission region and measured the ...

Stellar intensity interferometry is a powerful observational technique that exploits second-order coherence properties of starlight to achieve extremely high angular resolution. Building on the ...

Georgia State University's Center for High Angular Resolution Astronomy (CHARA), a six-telescope interferometer, excels at studying stars. It's been observing them for 20 years and has contributed to ...

Using interferometry, an international team led by an astronomer of Paris Observatory (LESIA) obtained an unprecedented image of the surface of the red supergiant Betelgeuse, in the constellation of ...

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 ...

Researchers from the University of Arizona, University of Maryland, and NASA’s Goddard Space Flight Center have proposed a new method for achieving ultra-high-resolution astronomical images using ...

An image of the spiral galaxy NGC 1086 obtained by the European Southern Observatory’s Very Large Telescope (VLT). The galaxy has a distance of 47 million light-years and is one of the nearest ...

Consider this: astronomers think of the Hubble Space Telescope as small. That might surprise you because after three decades' worth of images from Hubble with depth and detail most ground-based ...
