Bubble Nebula by Hubble Heritage Via Flickr: For the 26th birthday of NASA’s Hubble Space Telescope, astronomers are highlighting a Hubble image of an enormous bubble being blown into space by a super-hot, massive star. The Hubble image of the Bubble Nebula, or NGC 7635, was chosen to mark the 26th anniversary of the launch of Hubble into Earth orbit by the STS-31 space shuttle crew on April 24, 1990. The Bubble Nebula is 7 light-years across — about one-and-a-half times the distance from our sun to its nearest stellar neighbor, Alpha Centauri. The Bubble Nebula was discovered in 1787 by William Herschel, a prominent British astronomer. It is being formed by a prototypical Wolf-Rayet star, an extremely bright, massive, and short-lived star that has lost most of its outer hydrogen and is now fusing helium into heavier elements. The star is about 4 million years old, and in 10 million to 20 million years, it will likely detonate as a supernova.

Cargo transfer bags come in various sizes.  I actually fit into this one and as a joke, Thomas and Shane took me over to the Russian segment, zipped inside.  They told them there was a present inside and opened it up.  I popped out and gave them a good surprise!

Comet Catalina Emerges : Comet Catalina is ready for its close-up. The giant snowball from the outer Solar System, known formally as C/2013 US10 tails, making it an impressive object for binoculars and long-exposure cameras. The featured image was taken last week from the Canary Islands, off the northwest coast of Africa. Sky enthusiasts around the world will surely be tracking the comet over the next few months to see how it evolves. via NASA
