Nova explosions, which were thought until now to be relatively simple, are actually turning out to be very different. An ...

Published in Astronomy & Astrophysics, two new studies present an in-depth analysis of the planet Beta Pictoris b's ...

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 ...

Using Georgia State’s CHARA Array, an international team of scientists has uncovered unexpected complexity in how stars ...

Astronomers have obtained remarkably detailed images of two stellar explosions -- called novae -- just days after they began.

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 ...

New high-resolution images show that novae are anything but simple stellar fireworks. One exploded with multiple gas streams ...

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 ...

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 ...
