| This is a picture of cool hydrogen clouds in the Carina Nebula, also known as NGC 3372. These great clouds of cold hydrogen resemble summer afternoon thunderheads. They tower above the surface of a molecular cloud on the edge of the nebula. So-called "elephant trunk" pillars resist being heated and eaten away by blistering ultraviolet radiation from the nebula's brightest stars. The Carina Nebula is 7,500 lighgt-years away from Earth. One light-year = traveling @ 186,000 miles per second, x 60 seconds per minute, x 60 minutes per hour, x 24 hours in one day, x 365 days per year! Multiplied By 7,500 To Reach The Carina Nebula! |
