This Glowing Pink Nebula Light up a Satellite Galaxy of the Milky Way
This glowing nebula, named NGC 248, is located within the Small Magellanic Cloud, a satellite galaxy of the Milky Way and about 200 000 light-years from Earth. The nebula was observed with Hubble's Advanced Camera for Surveys in Sept. 2015, as part of a survey called the Small Magellanic cloud Investigation of Dust and Gas Evolution (SMIDGE).

NASA space telescope observes awesome views. Recently, it viewed glowing nebula in pink that’s located in Small Magellanic Cloud, 200,000 light-years away, but still the telescope can see it.

NASA space telescope observes awesome views. Recently, it viewed glowing nebula in pink that’s located in Magellanic cloud, 200,000 light-years away, but still the telescope can see it. In a collective form, the Nebula is called NGC 248.

Milky Way galaxy is a combination of several galaxies, including local group. Milky Way is a huge part of this group that has several small galaxies around it. A good example is that of  Magellanic Clouds which a naked eye can easily see from the Southern Hemisphere.

NASA/ESA Hubble Space Telescope took a picture of small galaxy in Magellanic. The cloud emits nebula that glow with pink light. According to NASA scientists, the glow is due to strong radiations from central stars that gives hydrogen a pink glow.

NGC 248 was discovered for the first time by an astronomer Sir John Herschel in 1836. Nebulae length is 60 light years, and width is 20 light years. There are several nebulae that exist in small cloud, and NGC 248 is located in the Southern Hemisphere known Tucana i.e. 200,000 light-years away.

Nebulae were discovered during Hubble’s survey known as SMIDGE, Small Magellanic cloud Investigation of Dust and Gas Evolution. The purpose of this survey is to detect how small cloud dusts, and see its difference from the Milky Way. The scientists found that the dust is similar to Milky Way, like it was in the early universe.

The discovery will help NASA scientists to understand the history of our galaxy. According to the scientists, most galaxies occurred during earlier periods of the universe when there was little amount of heavy elements in the Milky Way. This amount was lower than the elements which are present in Milky Way in this age.  NASA/ESA Hubble Space Telescope did this survey in 2015.
