First Hint of Sunrise From Space

On July 30, 2013, Expedition 36 Flight Engineer Karen L. Nyberg of NASA took this photograph of a sunrise viewed from the International Space Station. As the space station orbits the Earth every 90 minutes, traveling at about 17,500 miles per hour, the crew sees about 16 sunrises and sunsets daily. > Karen Nyberg (@AstroKarenN) on Twitter Image Credit: NASA (More at NASA Picture of The Day)

Two Moons Passing in the Night

The Saturn moons Mimas and Pandora remind us of how different they are when they appear together, as in this image taken by NASA's Cassini spacecraft. Pandora's small size means that it lacks sufficient gravity to pull itself into a round shape like its larger sibling, Mimas. Researchers believe that the elongated shape of Pandora (50 miles, or 81 kilometers across) may hold clues to how it and other moons near Saturn's rings formed. This view looks toward the anti-Saturn hemisphere of Mimas…

Cloud Streets over the Bering Sea

In early April 2013, clouds stretched in parallel rows for hundreds of kilometers over the Bering Sea. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this natural-color image of the phenomenon on April 7, 2013. The parallel clouds, known as cloud streets, originated along the edge of the sea ice, which extended southward from the snow-covered expanses of Russia and Alaska. The location of the cloud formation was not a coincidence. When cold air…

Labyrinth, by Lois McMaster Bujold

Labyrinth, by Lois McMaster Bujold

This is the next up in this author's Vorkosigan series which I am intermittently working through, following Ethan of Athos which I reviewed in March. That one was unusual in that it did not feature Bujold's hero Miles, a junior officer in the Barrayan Imperial Security service, but he returns in Labyrinth in his role as Admiral Naismith of the Dendarii Free Mercenary Fleet. He is making a visit to Jackson's Whole, an…

Hello from San Diego, CA…

Hello fellow sci-fi fans!

Since self-publishing my first sci-fi book I can say, at some level, that I'm a sci-fi writer. The story evolved over a 10 year period and it took another 10 years to write (I had to learn to write books). All feedback from readers on my first book has been good and Kirkus Reviews has given my book a fantastic review! I think I can safely say it's a 'good' book. Anyone interested in the Kirkus review can see it…

Hubble Eyes a Mysterious Old Spiral

This striking cosmic whirl is the center of galaxy NGC 524, as seen with the NASA/ESA Hubble Space Telescope. This galaxy is located in the constellation of Pisces, some 90 million light-years from Earth. NGC 524 is a lenticular galaxy. Lenticular galaxies are believed to be an intermediate state in galactic evolution — they are neither elliptical nor spiral. Spirals are middle-aged galaxies with vast, pin wheeling arms that contain millions of stars. Along with these stars are large clouds of…
