A beautiful death
When a star like our sun uses up all of the hydrogen in its core, it becomes what is called a “planetary nebula.” The star sheds its outer layers of gas, leaving behind a hot core.
This composite image of NGC 2392 includes data from NASA’s Chandra Space Telescope, showing the location of million-degree gas near the center of the planetary nebula in pink. Readings from the Hubble Space Telescope - colored red, green, and blue - show the intricate pattern of the outer layers of the star that have been ejected.

Happy Birthday NASA!

July 29, 1958: NASA is Created
On this day in 1958, the United States Congress passed legislation creating the National Aeronautics and Space Administration (NASA). Since its creation, NASA has played a vital role in coordinating all of the US’ activity in space. The agency spearheads and sponsors space exhibitions and has launched numerous orbiting satellites that have produced information about the solar system and universe.
In recent years, many feel that NASA has experienced numerous setbacks. The most significant being the end of the space shuttle program in 2011.
Celebrate NASA’s birthday with PBS NewsHour’s video of the agency’s newest vehicle “Curiosity.”

Boldly 3-D printing where no one has 3-D printed before.

Planetary Resources, the innovative, bold company with plans to strip-mine asteroids for their valuable resources, has revealed it will use advanced 3-D printing techniques to produce its line of Arkyd space telescopes.

And NASA just successfully test-fired a rocket engine that uses a 3-D printed injector component. The advantage of 3-D printing this part is the speed and precision of the process, which NASA notes would otherwise have required a year of careful machining to makeIt doesn’t hurt that it also cost 70% less to produce…
