Able to detect gravitational waves and visible light sources, ESO's BlackGEM telescopic array at La Silla Observatory in Chile is on the hunt for ripples in space-time. And unlike existing observatories, it can pinpoint where they're coming from.

Astronomers from the Event Horizon Telescope Collaboration have today revealed the first image of the supermassive black hole at the center of the Milky Way galaxy, produced using a network of radio telescopes around the world.

Astronomers may have detected a new exoplanet around Proxima Centauri, the star closest to our solar system. This tiny new world is one of the lightest ever discovered, which is even more impressive given the technique the team used to find it.

Astronomers have discovered the closest known pair of supermassive black holes – and that record has two meanings. Not only are they the closest pair to Earth, but they’re the closest to each other as well, heading for an eventual monster merger.

Astronomers have captured the first clear images of a colossal moon-forming debris disk orbiting a distant alien planet. According to the authors of the new study, the disk has enough material to create three satellites the size of Earth’s Moon.

The dual disk structure of our home galaxy may not be as unique as once thought, according to the results of a new study that probed the cross section of a spiral galaxy orbiting the Milky Way, some 320 million light years from Earth.

The first comet known to visit our Sun after being born around an alien star may be the most pristine comet ever discovered, new research has found.

Astronomers have discovered the aftermath of a cosmic hit-and-run in our own neighborhood. While studying the closest star cluster to the Sun, ESA scientists realized it may have been disrupted by a huge lump of invisible mass, possibly dark matter.

Astronomers have discovered a nearby system of exoplanets with unusually orderly orbits but disordered densities. Five of the six planets circle the star in a rare rhythmic dance called a resonance chain, while their densities are weirdly shuffled.

Astronomers have witnessed a rare celestial light show – a star being stretched into “spaghetti” by a black hole. More than 200 million light-years from Earth, the dying star was ripped to shreds by immense gravitational forces over six months.

The way things are in our solar system aren't always how they work elsewhere in the universe. Now, astronomers have observed a triple star system that’s warping and splitting its planetary disc into strange new shapes and multiple rings.

Astronomers have discovered the intact, exposed core of a gas giant locked in a close orbit around a Sun-like star. The discovery will give astronomers a rare opportunity to probe the heart of an ancient alien world.
