Applied Technology Institute (ATI Courses) is always following the amazing discoveries made by NASA.  We are sure that the students that attend our Satellites & Space-Related courses are doing so as well. Two new findings this week are worth a look. First is the end of a star’s life as seen by telescopes including the Chandra X-ray telescope. Second is a rare blue planet that it could be a sci-fi fantasy. First, the star. Stars like our sun die when they run out of the hydrogen at their cores. It will happen to our sun, too, in about 5 billion years. They cool and expand outward until a super-fast wind carries away their layers leaving behind a hot core. The ejections from that core and the outer layers create the complex images shown above. In purple, captured by Chandra, is the million-degree gas at the center of the nebula. The red, green and blue parts are ejected layers captured by the Hubble Space Telescope. Read more about the process here. The Chandra telescope program is managed by Huntsville’s Marshall Space Flight Center. Now, the blue planet. Scientists using the Hubble Space Telescope deduced the color of this planet orbiting a star 63 light years away. Seen from space, it would look like the famous images of Earth captured by the Apollo astronauts, but this planet is no Earth. Its daytime temperature is 2,000 degrees Fahrenheit, and NASA the atmosphere may rain glass – sideways – in “howling, 4,500-mph winds.” The color isn’t a reflection of oceans, as it is on Earth, but of the silicate in the atmosphere that scatters blue light.
