NASA researchers explore a hybrid observatory using a space-based starshade and ground telescopes to improve direct imaging and detect hidden Earth-like exoplanets.

Plans are underway to add a seventh movable telescope to Georgia State University’s Center for High Angular Resolution Astronomy— known as the CHARA Array—that would increase the resolution, or the ...

The highest angular resolutions for telescopes can be achieved by arrays of telescopes called astronomical interferometers. Hypertelescopes are being worked on that would combine many, many telescopes ...

According to the widely accepted Rayleigh criterion, in order to resolve two distant point sources, their angular separation must be larger than 1.22 (the wavelength of light divided by the ...

The James Webb Space Telescope has captured images of three nearby galaxies with unprecedented resolution at infrared wavelengths, giving them a first look at star formation, gas and dust. Data has ...

Finding Earth-like planets orbiting sun-like stars and identifying signs of life such as oxygen or water is a major goal in ...

The Event Horizon Telescope (EHT) Collaboration has conducted test observations achieving the highest resolution ever obtained from the surface of the Earth, by detecting light from the centers of ...

A ground-based telescope in Chile has shared its highest-resolution image ever, showcasing the final stages of star evolution within our galaxy 1,350 light-years from Earth. The telescope is ...
