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 ...

The dream of finding life on an alien Earth-like world is hampered by a number of technical challenges. Not the least of which is that the Earth is dwarfed by the size and brightness of the sun. We ...

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 ...

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 ...

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 ...

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 ...
