Living on Mercury Would Be Hard (Infographic) By Karl Tate, Infographics Artist - Conditions on the planet Mercury would make living there a challenge. See what the days and nights might be like on the closest planet to the sun in our infographic.
The Trifid Nebula (aka M20) lies @ 5,000 lya toward the nebula rich constellation Sagittarius. A star forming region illustrates 3 types of nebulae: red emission, dominated by light emitted by hydrogen atoms, blue reflection, produced by dust reflecting starlight & dark nebulae. Pillars & jets sculpted by newborn stars, below & left of the emission nebula's center, appear in Hubble's close-up images. The Trifid Nebula is about 40 light-years across.
The Carina Nebula (catalogued as NGC 3372; also known as the Grand Nebula, Great Nebula in Carina, or Eta Carinae Nebula) is a large, complex area of bright and dark nebulosity in the constellation Carina, and is located in the Carina–Sagittarius Arm. The nebula lies at an estimated distance between 6,500 and 10,000 light-years (2,000 and 3,100 pc) from Earth
