These distortions can occur when light from an astronomical object passes through the Earth’s atmosphere, for example. Adaptive optics (AO) corrects eye aberrations for sharp imaging ...

Astronomers have made a groundbreaking discovery: a binary star orbiting perilously close to the supermassive black hole at the center of our galaxy, Sagittarius A*. This stellar pair defies ...

She arrived on the front end of what was going to become a blazing meteor of innovation in astronomy. As she entered the field ... The next leap came with another new technology, adaptive optics (AO), ...

(Operated by the National Astronomical Observatory of Japan ... called—brace yourself—the Subaru Coronagraphic Extreme Adaptive Optics (SCExAO, pronounced “skex-a-o”).

Abstract: Atmospheric turbulence generates wavefront distortions in light rays from distant sources, thus reducing the resolution of astronomical images. Adaptive Optics (AO) systems enhance ...

Abstract: Imaging an astronomical object from a ground location suffers from atmospheric turbulence degrading the quality of the image. Adaptive optics systems use bright guide-stars to estimate the ...

Finalising the syllabus for the National Eligibility-Entrance Test Undergraduate (NEET-UG) 2025 examination, the ...

In honor of the telescope's 35th anniversary, NASA and the Astronomical League are launching an observation challenge, encouraging skywatchers on the ground to search the skies for the same ...

While it's definitely cold out there, even in Florida, the problem is that there are actually two different definitions of winter: meteorological and astronomical. So depending on which one you're ...

Earthlings get a second chance to see a blood moon in 2025, as a total lunar eclipse envelopes Europe, Africa, Asia and Australia on the evening of September 7. Earth’s shadow will begin ...
