Astronomers have captured the first close-up image of a star beyond our galaxy, taken during a dramatic moment near the end of the star’s life. In it, the “behemoth” star appears to puff out gas and ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

Three of the four Auxiliary Telescopes of the Very Large Telescope Interferometer in Chile that were used in this study are visible in this photo. Sandwiched between the orange glow of the sunset and ...

A brilliant comet waved its tail above the site of the world's largest telescope as it lit up the night sky last month. Comet C/2024 G3 (ATLAS) soared through the starry skies above the European ...
