Galactic eyelet

True beauty does not come from the inside, but from the depths of the cosmos

So some galaxy was blurred smoothly before envy. Just as the seven million light-years distant spiral galaxy NGC 300 us "currently" present, she became the choice "Miss Galaxy" determines one of the front places. At least this seems to prove a current series of pictures, which is short of "La Silla Observatory" The European sadswarten (ESO) were included in Chile. NGC 300 does not impress with optical stimuli. The new pictures of the spiral galaxy are also pronounced "informative".

For professionals, initiates, insiders, hobby asas and scientific interested people, it is an old hat that no one might set up anymore. The much cited realization that every look at the moon, every look to the sun, every look into the star sky (strictly speaking even every look no matter where) is at the same time a look in the past, many of them only acknowledge with a mude augurloria. That’s cold coffee. Nothing new. old news. And yet, many people were not all aware that the sparkle of the stars and the highest rare flash of Supernovae or the pulsation of neutron stars are nothing but interstellar cosmograms from the distant past, if they are correct "had read" will be informative, highest informative.

Especially thanks to the ever better instrumentation, the astronomers dive on their "optical" Time travel continuously deeper into the past and learn more and more about that "Life" and the decline of the stars and galaxies.

Astro photo "the end" Further past

Seven million years immersed in the past are now also astronomers of La Silla Observatory in Chile. Using the wide-angle camera Wide-Field Imagers (WFI) of the 2.2-meter telescope, they started a spectacular, beautifully picture that comes from a time when the grooming of Homo Sapiens Sapiens in the encyclopadia of evolution is still an unwritten chapter was.

The astro photo "the end" Furthermore, a foreign milk strain showing in the constellation sculptor (sculptor on the sideline starry sky and pays to the rough and unquestionably with the most beautiful spiral galaxies in the universe. In the sky, the galaxy extends with the catalog number NGC 300 – the short NGC to be applied to galaxies is UBRIGEN for New General Catalogue of Nebulae and Clusters of Stars – over an angle of 25 angular minutes, which corresponds approximately to the rough of the full moon. Already with good binoculars, the spiral structure of NGC 300 is well recognized.

That the Cosmic perspective shines soil spiral galaxy in such beauty and color splendor, was only possible through the combination of numerous shots. The astronomers of the European sadsternewarten ESO succeeded in adding a series of star system to an asthetic color recording a series of 278 images of the seven million light-years away.

NGC 300-BILD dismantled over 100 Cepheiden and 100.00 Other galaxies



On the short-mentioned astro images, the astronomers revolted over 100 Cepheid, with which they could determine the distance to NGC 300 with unprecedented accuracy.

Cepheides are pulsating stars whose light serves astronomers – similarly to a lighthouse – as a cosmic orientation point: but involuntarily for the determination of distances in all. Is significant for Cepheiden that their luminosity is in a particular period of which the star has the same brightness after a precisely determinable time again as before. With the relationship between the brightness of a Cepheid and the period with which its brightness fluctuates, the researchers can calculate how bright the star is de facto and at the same time determine its distance to the earth.

Due to the fact that NGC 300 has so many Cepheiden, the spiral galaxy will undoubtedly be an important cornerstone for the mixing of the cosmos in the foreseeable future.

Incidentally, the scientists spilled around 100 in the nearer environment of NGC 300.000 other galaxies, which nevertheless in far large distance to the earth "settled" are. The fact that some of these remote systems have a bizarre-bizarre and therefore distorted in the pictures is to return to the so-called gravitational lens effect, which causes NGC 300.

After all, the astronomers can accurately determine the distribution of matter in NGC 300 thanks to this effect, possibly even in this way the secret of the "Dark matter" A stucco close coming, which makes a coarse part of the mass of each star system and the – nomen Est omen – is difficult to identify only.

The NGC-300 image in high resolution is wonderful as a desktop wallpaper.
