Quasars: Brightest Objects in the Universe | Space.com This artist's concept illustrates a quasar, or feeding black hole, similar to APM 08279+5255, where astronomers discovered huge amounts of water vapor. Gas and dust likely form a torus around the central black hole, with clouds of charged gas above and below. CREDIT: NASA/ESA
Friday, December 2, 2011: Two large coronal mass ejections (CMEs) occurred during November 12-14, 2011, as observed by STEREO Ahead spacecraft's coronagraph. A halo CME event took place first, during which the leading edge of the particle cloud expanded in an arc around the sun. The cloud headed towards the Ahead spacecraft. In the second, larger event the bright cloud headed out into space and away from Earth. The coronagraph's black disk blocks out the sun, represented by the white circle
Black holes are gigantic cosmic monsters, exotic objects whose gravity is so strong that not even light can escape their clutches. This is an artist's conception of a black hole in front of the Large Magellanic Cloud.

A giant, hungry black hole appears to be chowing down on cold, clumpy clouds at the center of a nearby galaxy, a new study finds. The black hole's dining habits are shedding light on how black holes throughout the universe may grow. At the heart of nearly every galaxy is a supermassive black hole millions to billions of times the mass of Earth's sun, most astrophysicists agree. These black holes grow by gobbling up gas, dust and anything else that falls on them (scientists call this process…
In August of 2007, astronomers located a gigantic hole in the universe. This empty space, stretching nearly a billion light-years across, is devoid of any matter such as galaxies, stars, and gas, and neither does it contain the strange and mysterious dark matter, which can be detected but not seen. The large void in the Constellation Eridanus appears to be improbable given current cosmological models. God told Job He was beyond the empty space... The Book of Job in the Holy Bible
An accumulation of 270 hours of Chandra observations of the central regions of the Perseus galaxy cluster reveals evidence of the turmoil that has wracked the cluster for hundreds of millions of years. One of the most massive objects in the universe, the cluster contains thousands of galaxies immersed in a vast cloud of multimillion degree gas with the mass equivalent of trillions of suns.
The centre of the Milky Way (pictured above) holds a dense concentration of mass, including clusters of stars and a black hole, and confirming dark matter collisions in this region would further our understanding of the universe
entaurus A, also known as NGC 5128, is an active lenticular galaxy about 11 million light years distant from Earth in the Centaurus constellation. It contains young blue star clusters, huge gas clouds and dark dust lanes. At the centre of all the activity in Centaurus A are what appears to be disks of matter being sucked into a super massive black hole which has a mass a billion times that of the Sun.
