Pencil Nebula

This magnificent picture thin, like a carefully woven threads, give the feeling that on the object labored diligent hand, workman. We have previously presented pictures Pencil Nebula, made ​​with the Space Telescope in Chile. Now propose to look at a photo taken by an amateur astronomer.

Martin Pugh took this picture Pencil Nebula or NGC 2736, at home in New South Wales, Australia.

Awaiting the next "doomsday" left in '93

Russian amateur astronomers have found in space potentially dangerous asteroid 2012 YQ1. This unique detection they made ​​to remotely control a remote observatory "Helen" in the Chilean Atacama Desert, where there is also a complex 8-meter VLT telescopes of the European Southern Observatory.

Given that "Elena" is one of the most advanced telescopes in use today, the likelihood that the researchers are wrong is extremely low. 

Secrets of icy Dione

Scientists find out some of the secrets of the fourth moon of Saturn. Dione is the fourth largest natural satellite of Saturn. Dione was release the famous Italian astronomer Giovanni Cassini in 1684. However, officially its current name the given satellite of has received only in 1847. Its diameter is 1 123.4 kilometers. This Saturnine satellite of consists predominantly of water ice with considerable admixture of stone breeds of in internal layers of. Scientists have made a similar postulation proceeding from the density of Dione.

The mystery of spiral galaxies and their mysterious sleeves

Astronomers have discovered the largest recognized spiral galaxies and they have identified the "skeleton" of the Milky Way. Our own Milky Way, most likely, is a spiral galaxy. Indeed, our solar system and the Earth are somewhere close to one of his whiskers, pulled back the sleeves.

And almost 70% of the galaxies closest to the Milky Way are a spiral. But despite their general morphology of galaxies, such as our form and retain their characteristic features, which remains a puzzle in astrophysics. Are their sleeves in spiral galaxies? Whether they can appear and disappear over time?

Classification of meteorites

While there are different classifications, one of the most important is the collecting feature of composition and origin of meteorites. In this division we find:

1) Primitive: is the most primitive material in the solar system (they have several billion years) that have remained virtually unchanged since they formed, ie never suffered melting or differentiation processes.

The universe is older than before idea

The European Planck spacecraft has gained the most accurate and detailed map ever made ​​of the oldest light in the universe. The results of this map suggest that the universe is expanding more slowly than scientists thought, and that is 13,800 million years, 100 million years older than previously believed. The data also show that in the universe there is less energy and dark matter than previously known.

Five quotation marks from Einstein on relativity

A day like today, namely the March 20, 1916, Albert Einstein formulated his theory of relativity. Here are five clever lines set by the German physicist about his most famous creation.

"When courting a beautiful girl, an hour seems like a second. But you sit on red hot coal; a second seems like an hour. That's relativity." Albert Einstein.
