Many widely known images of the galaxy have been taken by the Hubble Space Telescope, which turns 25 this year (time to rent a car!). NASA has created a fantastic video to discuss one of the later repairs to the Space Telescope Imaging Spectograph (STIS). It's a great example of geniuses at Johnson Space Center in Houston having to quickly come up with a solution when astronauts on a spacewalk could not correctly perform a repair.
Space is truly awe inspiring - and amazingly empty. It's often hard for us to conceptualize both the immense size of planets, stars, and other bodies with the incredible amount of space between them.
To show the immense size, introduced me to a fantastic YouTube video compared planet and star sizes. The video does a great job of showing relative size - once you think you're at the largest size possible, another body comes along and knocks it out of the park!
This background knowledge helps to fully appreciate the Pluto news as covered by the latest This Week in NASA video - check it out!
Pluto is an odd duck. It was known as the ninth planet until early in this millenium, when it was demoted to dwarf planet status. All of this and we never even got a good luck at Pluto!
The current New Horizons mission is out to changed that. Launched almost a decade ago, it took a three billion mile journey to Pluto, and below are the pics to prove it!
If you visit Google today, the awesome woman appearing on the Google Doodle is none other than the late Sally Ride, the first American woman in space.
Check out a Google "Behind the Doodle" video, which mentions other cool facts about Sally, such as the fact that she was a competitive college tennis player!
Also, make sure to check out Janelle Monae's homage to Sally.
