The black hole at the center of our galaxy is the subject of a groundbreaking new image from the Event Horizon Telescope collaboration. As the Event Horizon Telescope collected data for its remarkable new image of the Milky Way’s supermassive black hole, a legion of other telescopes including three NASA X-ray observatories in space was also […]
Since 2003, the black hole at the center of the Perseus galaxy cluster has been associated with sound. This is because astronomers discovered that pressure waves sent out by the black hole caused ripples in the cluster’s hot gas that could be translated into a note – one that humans cannot hear some 57 octaves […]
What are black holes? How do they form and evolve? What effect do they have on their surroundings and the rest of the Universe – and why should we care about them? ESA is working on answering these questions and many more using a suite of unique but complementary space missions. Even light cannot escape […]
This image from the NASA/ESA Hubble Space Telescope reveals tendrils of dark dust threading across the heart of the spiral galaxy NGC 7172. The galaxy lies approximately 110 million light-years from Earth in the constellation Piscis Austrinus. The lane of dust threading its way across NGC 7172 is obscuring the luminous heart of the galaxy, making NGC […]
In this illustration, light from a smaller black hole (left) curves around a larger black hole and forms an almost-mirror image on the other side. The gravity of a black hole can warp the fabric of space itself, such that light passing close to the black hole will follow a curved path around it. Credit: […]
The newly-found black hole was spotted in NGC 1850, a cluster of thousands of stars roughly 160,000 light-years away in the Large Magellanic Cloud, a neighbour galaxy of the Milky Way.
Scarier than a ghost? Black holes are regions in space where gravity is so strong that nothing can escape
Halloween is a time to be haunted by ghosts, goblins and ghouls, but nothing in the universe is scarier than a black hole.
A high-energy neutrino traced back to a violent encounter between a black hole and a star needs a different origin story, new research has found.
The first observation of a brand-new kind of supernova had been predicted by theorists but never before confirmed.
Stellar Collision Triggers Supernova Explosion – “This Is the First Time We’ve Actually Seen Such an Event”
Astronomers have found dramatic evidence that a black hole or neutron star spiraled its way into the core of a companion star and caused that companion to explode as a supernova.
