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 ...

Earth's atmosphere is an impediment to astronomical observations. Not only is cloudy weather a problem, but temperature fluctuations in the atmosphere mean that ground-based telescopes require ...

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 ...

An image of the spiral galaxy NGC 1068 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 ...

In about 11 years, one of humankind’s most ambitious missions is set to launch into space. Decades in the making, the Laser Interferometer Space Antenna, or LISA, could revolutionize our understanding ...

The post Ultra-High Resolution Telescope Catches A Glimpse Of Object That May Answer Key Questions About Dark Matter first on ...

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 picture of a ...

Engineers and technicians working on the James Webb Space Telescope successfully completed the first important optical measurement of Webb’s fully assembled primary mirror, called a Center of ...

The only major difference between the sun and the stars we see at night is that the sun happens to be close to us—which is advantageous, assuming you enjoy being alive. Astronomers enjoy this as well ...
