... February 23, 1997 . Cartwheel of Fortune . ... Explanation : By chance, a collision of two galaxies has created a surprisingly recognizable shape on a cosmic scale - "The Cartwheel Galaxy" . ... In fact, the ring-like shape is the result of the gravitational disruption caused by a small intruder galaxy passing through a large one, causing a a star formation wave to move out from the impact point like a ripple across the surface of a pond. ... But ... what happened to the small intruder galaxy ? ...

In this gallery are many images of Low Surface Brightness Galaxies which have recently been discovered and analyzed. ... The central surface brightness of this galaxy is 24.28 . Malin 2 This galaxy is another huge disk galaxy with a scale length of 15 kpc and a redshift of 15000 km/a. The high surface brightness knot in one of its spiral arms actually has the same color, luminosity and H-alpha equivalent width as the entire Large Magellanic Cloud . ... Truly it is a Low Surface Brightness Galaxy. ...

... George Benedict, University of Texas at Austin . ... Abstract . ... Quasars at Redshift z=6 and Early Star Formation History . ... The cosmic distance scale and dark energy are two key issues in modern astrophysics, and HST has played a vital role in probing both. On the one hand, HST has been involved in cosmic distance measurements since its inception, largely through the H 0 Key Project, which used WFPC2 to identify and photometer Cepheids in 31 spiral galaxies at distances from 60 to 400 Mpc. ...

... Each one is part of the galaxy we live in called the Milky Way. ... Galaxies come in a variety of shapes and sizes; many are spiral disc galaxies, like the Milky Way. ... For many years astronomers have believed that when two similar-sized spiral galaxies collide, they will mash together a type of galaxy called an elliptical galaxy, the shape of a giant squashed football. But, if two spiral galaxies make one elliptical galaxy, how are there still so many spiral galaxies in the Universe? ...

... February 22, 1999 . NGC 1316: After Galaxies Collide . ... WFPC2 , HST , NASA . ... A preliminary inspection indicates that NGC 1316 is an enormous elliptical galaxy that started devouring a smaller spiral galaxy neighbor about 100 million years ago. ... Most elliptical galaxies have more and brighter globular clusters than evident in NGC 1316 . ... One hypothesis therefore holds that these globulars survive from an even earlier galaxy that was subsumed into NGC 1316. ... About APOD > . ...

... A radio galaxy is a galaxy that emits an unusually big amount of energy at radio wavelengths. ... Inside of each galaxy with an active nucleus (radio galaxies are among them) there must be a system of a "central machine" responsible for the colossal amount of the emitted energy from radio to gamma ranges. ... Sometimes a radio source in an active galaxy may flare again if the needed conditions appear (a new portion of matter would fall into the furnace of the "central machine"). ...
