Saturn and Two Moons: Dione and Titan
Two of Saturn's Moons: Titan and Dione
You know….NASA’s Cassini spacecraft has taken some pretty amazing pictures, but this has to be one of the best. This image, released on December 22, 2011 shows Saturn’s largest moon, Titan, almost eclipsing Saturn’s fourth-largest moon, Dione. Fantastic!
A Barred Spiral Galaxy in a Sea of Galaxies!
Barred Spiral Galaxy - NGC 3259
How many galaxies can you count in this picture? This image of a barred spiral galaxy (NGC 3259) was released this week by the ESA/Hubble Team. What strikes me about this image is the sheer number of galaxies that appear to be surrounding this beautiful barred spiral galaxy. It’s almost as if the barred spiral galaxy is adrift in a sea of galaxies.
Giant Red Gas Bubble in Space
SNR B0509-67.5
I was browsing through images from the Hubble Space Telescope today and came across this beauty. Known as SNR 0509, the giant red gas bubble shown in the image above is the remnant of a violent supernova explosion. It was found in the Large Magellanic Cloud which is a small galaxy that lies about 160,000 light years away from Earth.
What do Scientists Consider the “Habitable Zone” for Planets?
The Kepler Space Telescope Spacecraft
You may have seen recent news stating that scientists have discovered several new planets that may support thanks to the Keplar Space Telescope, a spacecraft that is currently traveling through space and observing distant planets, stars, and solar systems. Thanks largely in part to the work being done by the Keplar Space Telescope, scientists have discovered around 2,300 planets that may be capable of supporting extraterrestrial life. However, this raises the question – what exactly is the Habitable Zone for planets, and what does this have to do with alien life?
