The accretion disk(circular rotating matter) solar system matter & nova remains/ binary star sucked into the hole.and jet (yet visible matter,subatomic breakdown, radiation) of a supermassive black hole. All spiral galaxies seem to have supermassive black holes at their center. That and dark matter (invisible) produce the galaxy the high speed of rotation. Jet is the still visible radiation from its breakdown of matter under it's gravity.
The planet-forming disk around the star HD 135344B, which is about 450 light-years away, has a spiral structure that was most likely created by protoplanets on their way to becoming Jupiter-like bodies. The central star is obscured in this image from the SPHERE instrument on ESO's Very Large Telescope in Chile.
Hubble Views the Whirling Disk, image from the NASA/ESA Hubble Space Telescope. It is one of the brightest lenticular galaxies known, a category that lies somewhere between spirals and ellipticals. It has hosted two known supernova explosions and is known to have a colossal supermassive black hole at its center that has the mass of 450 million suns. Virgo cluster of galaxies.
Three teams of astronomers used the SPHERE instrument on the Very Large Telescope to image protoplanetary disks around nearby stars and catch planet formation in action. The post Planet-forming Disks Revealed in Striking Images appeared first on Sky & Telescope.
Looking like a spiders web swirled into a spiral, the galaxy IC 342 presents its delicate pattern of dust in this image from NASAs Spitzer Space Telescope. Seen in infrared light, the faint starlight gives way to the glowing bright patterns of dust found throughout the galaxys disk.
A Tidal Galaxy "A previously unsuspected tidal dwarf galaxy candidate appears only in the ultraviolet, indicating the presence of many hot young stars as seen in this cool space Image. IC 4970, the small disk galaxy interacting with NGC 6872, is located above the spiral’s central region. The spiral is 522,000 light-years across from the tip of one outstretched arm to the tip of the other, which makes it about five times the size of our home galaxy, the Milky Way
