NASA Supports Event Horizon Telescope in Studying Milky Way’s Black Hole

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 […]

New NASA Black Hole Sonifications with a Remix

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 […]

Black holes

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 […]

Hubble Views a Galaxy with an Active Black Hole

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 […]

Astronomers Find Two Giant Black Holes Spiraling Toward a Collision

Astronomers Find Two Giant Black Holes Spiraling Toward a Collision

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: […]
