It will be used much more than this current one. Thankyou :)
"Nebulae, Galaxies & The Universe" is a blog dedicated to everything that resides within the ever expanding cosmos. All things related to the universe will be posted, from news articles to photographs of outer space, to inspirational quotes.
AM 0644-741 is an unbarred lenticular ring galaxy. There are many theories on how it got its odd shape. The favorite theory is that the oblong ring was shaped by a collision with another galaxy. The added gas from the collision had sparked star creation which is why the ring is filled with young blue stars.

The Known Universe takes viewers from the Himalayas through our atmosphere and the inky black of space to the afterglow of the Big Bang. Every star, planet, and quasar seen in the film is possible because of the world’s most complete four-dimensional map of the universe, the Digital Universe Atlas that is maintained and updated by astrophysicists at the American Museum of Natural History. The new film, created by the Museum, is part of an exhibition, Visions of the Cosmos: From the Milky Ocean to an Evolving Universe, at the Rubin Museum of Art in Manhattan through May 2010.

This is my favorite thing in the universe. It is a beautiful picture of gravitational lensing. The bright ball in the middle is the center of Huchra’s Lens. Huchra’s Lens is a galaxy which is about 400 million light years away. The 4 bright balls around Huchra’s Lens are actually the same quasar called Einsteins cross, which sits directly in the line of sight behind Huchra’s Lens about 8 billion light years away.
Basically you are actually seeing the same quasar 4 times around the near galaxy because the extreme gravity is bending the light around the center of the galaxy.
One day when I have a large enough telescope my dream is to find Einstein’s cross.
