Black sun on a star field reversed

Does it is known this strange black ball? If it is, is because it is the Sun

The image shown above is the result of a very detailed view of Sol registered in very specific color of red, then black and white processed and finally displayed in inverted colors. Once completed, the black sun was superimposed on a stellar field whose colors were also reversed.

The highlight allows treatment performed several long filaments , active regions dark bulges of the solar disk and a kind of mobile folder hot gas.

Dark energy has earned the most powerful digital camera

Eight billion years ago, the light rays create by distant galaxies started their way towards the ground. Now, on top of the mountain in Chile, these rays will be fixed with the help of the most powerful in the world of digital cameras. Among other things, the light of distant galaxies can help scientists understand the universe still be expanded and, if so, how concentrated the process.

Astronomers have calculated the ancestors of the Sun

Two astronomers at the Geneva Observatory, and Georges Mathieu Gunel Maine, recently declare that they were able to build out what looked like "ancestors" of our sun. As you know, the birth of stars is in the depth of the gas-dust clouds, "metals" which are the remains of already dead and exploding stars that were ejected into interstellar space and the force of the explosion that ultimately form these same gas and dust clouds.
