Nebula Cygnus Loop at 600 million pixels

Nebula Cygnus Loop at 600 million pixels

Among the activities taking place around space exploration, multiple research centers (such as NASA or the great astronomical observatories) often share some of the results of their research as part of their scientific outreach activity. One of the files usually have the greatest impact, besides being one of the most colorful are the photographs, whether of the Earth (as the series Black Marble that NASA shared a few days ago) and some special points of our Universe . In this sense, the last (and amazing) publication that has seen the light comes from the hand of the National Optical Observatory (NOAO) at Arizona (United States) who shared yesterday which is one of the largest astronomical images captured so the date, a photo of over 600 million pixels of the Cygnus Loop Nebula.

The photo, which in its original size weighs 1.65 GB (and indeed is available for download along with other more portable sizes) was captured by the camera Kitt Peak telescope (located in Arizona) and shows a part of supernova remnant that has given rise to the Cygnus Loop nebula, ie the remains of a star that exploded between 5,000 to 10,000 years.

Cygnus Loop is located about 1,500 light years from Earth and because of its size (in the sky occupies the equivalent of 45 times the surface of the Moon) contains within it many unique astronomical objects that have been cataloged along the years since the first time Cygnus Loop was cataloged in 1784 but, earlier, had already cataloged some objects that belong to it.

In Arizona observatory had since 2003 working on these observations and photographs but have had to spend nine years until the technology has enabled all these data could compose and unite them in a very high resolution image, a research also has served to show that, from Earth, large can still go a long way thanks to the new cameras available for research centers.

The picture, certainly, is to enjoy it.
