For astronomers, one of the greatest challenges is capturing images of objects and phenomena that are difficult to see using optical (or visible light) telescopes. This problem has been largely ...

HELSINKI — China aims to construct an array of telescopes in deep space to search for habitable planets orbiting other stars. The Miyin project envisions sending four light-collecting telescopes and a ...

This animation, provided by the Max-Planck Institute for Extraterrestrial Physics (MPE), shows the path of light inside GRAVITY+, an instrument and a large and complex upgrade to ESO’s Very Large ...

The digital data produced by each telescope within the observation process of Very Long Baseline Interferometry (VLBI) can be referred to as raw data. The raw telescope data represents the initial ...

For more than 400 years, astronomers both professional and amateur have taken a special interest in observing Mira stars, a class of variable red giants famous for pulsations that last for 80-1,000 ...

The successful creation of a guide star above the European Southern Observatory (ESO) Paranal site in Chile with freshly installed lasers marks a new era of interferometry, according to the ESO team.

If there is a very dense object such as a black hole or large star in the foreground, whatever is shining from behind it ...

When you look at the night sky, do you ever wonder what's going on out there? On a clear night with a dark sky, if moonlight doesn't wash it out, sometimes you can see the arc of the Milky Way. The ...

Consider this: astronomers think of the Hubble Space Telescope as small. That might surprise you because after three decades' worth of images from Hubble with depth and detail most ground-based ...

This photograph shows four lasers at ESO’s Paranal Observatory, each one launched from one of the four eight-metre telescopes on site. The launch of these lasers represents a significant milestone for ...
