Georgia State University's Center for High Angular Resolution Astronomy (CHARA), a six-telescope interferometer, excels at ...

The way to be certain is to observe the planet directly, but that would take a space telescope with a mirror 3–4 times that of Webb. Back in 2002, NASA proposed just such a mission.

NASA showed off a telescope prototype for a new gravitational wave detection mission in space. The telescope is part of the Laser Interferometer Space Antenna (LISA) mission led by the European ...

In fact, an interferometer's resolution is the same as a single telescope with a mirror that covers the entire distance between the telescopes. It feels like magic, honestly, but it's true.

And astronomers have a brand-new, superpowerful eye with which to see the changing cosmos: the Vera C. Rubin Observatory in ...

University of Arizona astronomers have now produced the highest resolution direct images ever taken of a supermassive black hole in the infrared, using the Large Binocular Telescope Interferometer ...

This is an image of the star WOH G64, taken by the GRAVITY instrument on the European Southern Observatory’s Very Large Telescope Interferometer (ESO’s VLTI). This is the first close-up ...

Ars Technica has been separating the signal from the noise for over 25 years. With our unique combination of technical savvy and wide-ranging interest in the technological arts and sciences, Ars ...

The PhaseCam interferometer verified that the surfaces of the Webb telescope’s mirror segments were as close to perfect as possible, and that they will remain that way in the cold vacuum of space.

An interferometer like the VLA or Farview can see the universe in much higher resolution than a filled-aperture telescope like FAST or LCRT, because the interferometer is wider.

NASA showed off a telescope prototype for a new gravitational wave detection mission in space. The telescope is part of the Laser Interferometer Space Antenna (LISA) mission led by the European ...

The Large Binocular Telescope Interferometer combines the light from both mirrors, allowing for much higher resolution observations than would be possible with each mirror on its own.
