On our home page this morning there were a series of slides from NASA showing some
of the views as seen through the Hubble Space telescope. Maybe some of you have not
seen any of these and might like to se them.
#1..Shows a pair of gravitationally interacting galaxies called Arp 147.
#2..This image shows the light echo around the variable star V 838 Monocerotis and
released Oct.27,2006. The unusual variable star continues to puzzle astronomers. This
previously inconspicuous star underwent an outburst early in 2002, during which it
temporarily increased in brightness to become 600,000 times more luminous than our sun.
#3...This image is a false-color picture showing the many sides of the supernova
remnant Cassiopeia A. It is made up of images taken by three of NASA's great
observatories, using three different wavebands of light. Infrared data from the
Spitzer Space Telescope are colored red; visible data from the Hubble Space Telescope
are yellow, and X-ray data from the Chandra X-ray Observatory are green and blue.
Astronomers have unearthed secrets from the grave of the star that blasted apart in a
supernova explosion long ago. The discovery represents the first time astronomers
have been able to resurrect the life history of a supernova remnant in our own galaxy.
Cassiopeia A is a burnt-out corpse of a masive star that ended it's life in a firery
supernova about 11,300 years ago. Because it is 11,000 light years from Earth, the
light from it's explosion would have reached Earth, sweeping right past about 300 years ago.
#4...The Cartwheel Galaxy. Another false-color composit image by the thre telescopes.
About 100 milion years ago, a smaller galaxy plunged through the heart of the Cartwheel
creating ripples of brief star formations. In this image,the first ripple appears as an
ultraviolet-bright blue outer ring. The blur outer ring is so powerful in the Galex
observations that it indicates the cartwheel is one of the most powerful UV-emitting galaxies
in the nearby universe. Although astronomers have not identified exactly which galaxy
colided with the cartwheel, two of the three candidate galaxies can be seenin this image
to the bottom left of the ring, one is a neon blob,and the other is a green spiral.
#5...An impressive pair of interacting galaxies with a feather-like galaxy crossing a companion
galaxy. The two components will probably merge to form a single galaxy in the future.
The pair is adorned with a number of bright blue star clusters.
I hope you enjoy something different again.
