Return to article list The renewed energy flowing from an active galaxy provides astronomers with a high-energy mystery to explore in detail at multiple wavelengths. This artist's impression shows two stages in the formation of a disk of gas and dust around the enormous black hole at the center of the galaxy SDSS1335+0728. The core
Dwarf galaxies like NGC 5264 are thought to host smaller versions of the supermassive black holes found at the centers of all massive galaxies.

43 Using data from NASA's retired Spitzer Space Telescope, scientists have gained new insights into the feeding habits of supermassive black holes at the centers of galaxies across the universe. These black holes often fluctuate in brightness due to the huge clumps of cosmic material falling into them. However, this is not true for black
This artist's impression shows the binary system VFTS 243, located in the Tarantula Nebula in the Large Magellanic Cloud. The sizes are not to scale: in reality, the blue-white star is about 200,000 times larger than the black hole. The lensing effect around the black hole is shown for illustrative purposes only, to make this
