EMBARGOED UNTIL: 9:20 AM CST, January 6, 1999 CONTACT: John Biretta Space Telecsope Science Institute, Baltimore, MD (Phone: (410) 338-4917; Internet: biretta@stsci.edu) HUBBLE DETECTS FASTER-THAN-LIGHT MOTION IN GALAXY M87 Astronomers reported today discovering clouds which appear to move many times faster than the speed of light, shooting out from the region of a black hole at the center of the M87 galaxy. ... It's an illusion created by the finite speed of light and rapid motion," Biretta said. ...

This picture from the NASA/ESA Hubble Space Telescope shows the most distant gravitational lens yet discovered. The glow at the center of this picture is the central regions of a normal galaxy. By chance, it is precisely aligned with a much more remote young star-forming galaxy. The light from the more distant object is bent around the nearer object by its strong gravitational pull to form a ring of multiple images. ... NASA/ESA/A. van der Wel ...

SAOtng can associate names with region markers in order to aid users in remembering the significance of the region. ... By default, marker regions that you create in SAOtng are defined to be either "source" regions or "background" regions and are colored green and red, respectively. ... This type name is controlled by the "Set Type (and Color)" option in the marker menu (activated using the right mouse button within a region). ... Colors can be associated with names for regions. ...

... Comet Animation . ... Comet structures are diverse and very dynamic, but they all develop a surrounding cloud of diffuse material, called a coma, that usually grows in size and brightness as the comet approaches the Sun. ... As comets approach the Sun they develop enormous tails of luminous material that extend for millions of kilometers from the head, away from the Sun. ... The evaporated molecules boil off and carry small solid particles with them, forming the comet's coma of gas and dust. ...

... A big bright star near the center of the red region appears white hot and emits light so energetic . A Distant Cluster of Galaxies . ... In this 1994 Hubble Space Telescope photograph, every bright object is a galaxy. Oddly - most of them are spiral galaxies. This rich cluster of galaxies, named CL 0939+4713, is almost half way across the visible universe. ... In this dramatic picture, spiral galaxy NGC 5091 appears in the foreground. ... Can you see through the spiral galaxy? ...

... A tussle in the distant Universe. This Hubble Space Telescope image shows evidence for a merger between a quasar and a companion galaxy. The quasar is the bright object just beneath the image center, and the wisps of material around it are remains of a galaxy disrupted by the interaction between it and the quasar. ... Galactic Nuclei: Old Quasars? Quasars as Probes of the Distant Universe . ... Quasars. ... The name quasar is made up with parts of the words "quasi-stellar radio." ...

... Feeding the Monster: Gas Caught in its Death Spiral into a Massive Black Hole . ... Stromlo Professor Mike Dopita have used the Hubble Space Telescope to discover how a massive Black Hole in a nearby galaxy feeds itself. ... Earlier Hubble Telescope data obtained by another team member, Professor Holland Ford of Johns Hopkins University in Baltimore, Maryland, had found a disk of gas rushing around the Black Hole at a speed of 500 kilometers a second. ...

In 1950 Jan Oort noticed that . no comet has been observed with an orbit that indicates that it came from interstellar space, . ... From this he proposed that comets reside in a vast cloud at the outer reaches of the solar system. ... Unfortunately, since the individual comets are so small and at such large distances, we have no direct evidence about the Oort Cloud. ... Its orbit is intermediate between the Kuiper Belt and what was previously thought to be the inner part of the Oort Cloud. ...
