안녕하세요, 프리덤 알제이입니다. 

오늘은 NASA에서 어떤 우주의 모습을 보여주는지 궁금합니다.

이 사진의 제목은 Three Galaxies in Draco 입니다. 

NASA에서의 공식적으로 제공한 설명을 보시죠.

 

<This tantalizing trio of galaxies sometimes called the Draco Group, is located in the northern constellation of (you guessed it) Draco, the Dragon. From left to right are face-on spiral NGC 5985, elliptical galaxy NGC 5982, and edge-on spiral NGC 5981, all found within this single telescopic field of view that spans a little more than the width of the full moon. While the group is far too small to be a galaxy cluster, and has not been catalogued as a compact galaxy group, the three galaxies all do lie roughly 100 million light-years from planet Earth. Not as well known as other tight groupings of galaxies, the contrast in visual appearance still makes this triplet an attractive subject for astroimagers. On close examination with spectrographs, the bright core of striking spiral NGC 5985 shows prominent emission in specific wavelengths of light, prompting astronomers to classify it as a Seyfert, a type of active galaxy. This impressively deep exposure hints at a faint dim halo along with sharp-edged shells surrounding elliptical NGC 5982, evidence of past galactic mergers. It also reveals many even more distant background galaxies.;

 

오늘도 흥미로운 우주, 광할한 우주영상을 보며, 그 우주에 살고있는 저희가 위대해 보입니다.

오늘도 즐거운 하루 되시고, 우주 영상/사진은 꾸준히 업로드 되니 꼭 또 구경오세요.
