In the popular imagination, it was thought that capturing an image of a black hole was impossible because an image of something from which no light can escape would appear completely black. NGC 547 has an active galactic nucleus at its core, an extremely bright region with a supermassive black hole in the center.Find out how scientists created a virtual telescope as large as Earth itself to capture the first image of a black hole's silhouette.Īccomplishing what was previously thought to be impossible, a team of international astronomers has captured an image of a black hole’s silhouette.Įvidence of the existence of black holes – mysterious places in space where nothing, not even light, can escape – has existed for quite some time, and astronomers have long observed the effects on the surroundings of these phenomena. Hubble Spots an Energetic Galaxy: A NASA Hubble Space Telescope image reveals NGC 547, an elliptical galaxy that sits about 250 million light-years away from Earth in the constellation Cetus.'H' is for Hot and Huge in Chandra Image: With a single letter seemingly etched in the X-ray glow around it, a giant black hole at the center of a massive elliptical galaxy is making a mark on its surroundings.
Its extreme brightness is caused by matter whirling into a supermassive black hole at the galaxy’s heart. An AGN is an extraordinarily luminous central region of a galaxy. These galaxies contain active galactic nuclei, or AGNs.

If there's a black hole nearby, maybe.Credit: NASA's Goddard Space Flight Center This is a Seyfert galaxy, a class of galaxies that have bright cores – called active galactic nuclei –powered by supermassive black holes.īlack holes can be hard to find unless you know what you’re looking for. Hubble Gazes at the Home of an Enormous Black Hole: A NASA Hubble Space Telescope image looks at a small section of the spiral galaxy NGC 4395.In the center of this galaxy is a supermassive black hole feeding off the gas and dust encircling it, and large jets of high-energy particles and other material spewing out. Galaxy With Black Hole Shines In Image From NASA’s Chandra and IXPE: The galaxy Centaurus A shines bright in this image combining data from multiple observatories.A Mesmerizing Model of Monster Black Holes: A supercomputer simulation is helping scientists understand what kind of light gas would produced around two supermassive black hole systems as they spiral toward a merger.The AGN sits at the center of the galaxy, is extremely bright, and emits radiation across the entire electromagnetic spectrum as the supermassive black hole at its core devours material that gets too close. Hubble Observes an In-between Galaxy: NASA’s Hubble Space Telescope captured an image of the lenticular galaxy NGC 3489, which has an active galactic nucleus, or AGN.These monsters lurk in the centers of most big galaxies, including our own Milky Way, and contain between 100,000 and tens of billions of times more mass than our Sun. NASA Animation Sizes Up the Universe’s Biggest Black Holes: A new NASA animation highlights the “super” in supermassive black holes.Credit: NASA's Goddard Space Flight Center Conceptual Image Lab Scientists think all of these objects shine most intensely in ultraviolet light. Smaller black holes are shown in bluish colors because their gas is expected to be hotter than that orbiting larger ones. Only one of these colossal objects resides in our own galaxy, and it lies 26,000 light-years away.
The black holes shown, which range from 100,000 to more than 60 billion times our Sun’s mass, are scaled according to the sizes of their shadows – a circular zone about twice the size of their event horizons. Watch this video to see how they compare to each other and to our solar system.
