![]() ![]() ![]() They are quasars, incredibly bright sources of light caused by matter heating up and falling into supermassive black holes in galaxies literally billions of light-years from us," Hubble researchers explained. Then there are the three extra bright objects, which are strange interlopers that do not belong to galaxy NGC 1073 or our own Milky Way. A bright X-ray source known as IXO 5 is located inside the ring and is most likely a binary system containing a star and black hole locked in orbit around each other.Īt the top of the image are several objects with a reddish hue, each of which is a distant galaxy lurking far beyond NGC 1073, researchers said. The Hubble image also reveals an odd, rough ring-like structure around the galaxy that is the result of recent star formation, according to a photo description. ![]() In fact, about one-fifth of the spiral galaxies from early universe contain bars, while more than two-thirds of spirals seen today have them, researchers said.Īdding to this idea is the fact that bars are more often found in galaxies full of older, redder stars, and less often in galaxies with bluer, younger stars, researchers said. Scientists think these might form as galaxies age, in part because very distant galaxies dating from the universe's early days tend not to have them. The universe is rife with spiral galaxies both with and without central bars. This inflow of gas can also feed the hungry giant black holes thought to inhabit the centers of most such galaxies. The bars, made of dense lines of stars at the galaxies' centers, are thought to form as gravity causes density waves that push gas inward, supplying material for new stars, Hubble mission researchers explained in a statement. By looking at cosmic wonders thought to be similar to our own galactic home, astronomers hope to learn more about the Milky Way, which we can see from only the inside. ![]()
