Hubble spots a space invader!
- Object is really a mirage created by the gravitational field of a foreground cluster of galaxies warping space
- The effect, called gravitational lensing, is used to improve Hubble’s view of far away galaxies
It may look like an attacker from a 1980s computer game, but Nasa today revealed this photo taken by Hubble of a massive cluster of galaxies two billion light years from Earth is an optical illusion.
Called Abell 68, the object is really a mirage created by the gravitational field of a foreground cluster of galaxies warping space and distorting the background images of more distant galaxies.
This effect, called gravitational lensing, can make multiple mirror image copies of the light coming from a far-flung galaxy.
Abell 68, pictured here in infrared light, is a galaxy cluster. Hubble operators were stunned to see what looks like a space invader’ character – but in…SEE- http://alien-ufo-community.ning.com/forum/topics/hubble-spots-a-space-invader-the-amazing-image-that-seems-to-show
The photo is amazing and strangely beautiful.
