Earth forces have sent an expedition to the Martian moon of Phobos, but to the disappointment of Doom fans there's no hell-portal in sight. What there is (and it's significantly more spectacular than an ancient video game) is an awesome view of both moons at once: Phobos and Deimos passing the probe in a Mars-centric three way.
You wouldn’t believe it, but our own sun is actually relatively small and uneventful. According to Rosina Iping, of the Catholic University, Washington, our sun has remained pretty much the same for four billion years. However, a cosmic event of massive proportions taking place in a galaxy orbiting the Milky Way is providing astronomers with insights in to the lives of much larger celestial bodies.
To the untrained eye, the image of the Grand Design galaxy, or M81, looks strikingly like what our own Milky Way would look like from space. The sharpness and clarity of the new photo, taken by NASA’s Hubble Space Telescope, makes it the most detailed image ever taken of the galaxy. The subtle differences between M81 and the Milky Way, however, include a smaller black hole and a smaller bulge at our center, as well as cleaner-looking spiral arms.
The Hubble Telescope has been patrolling the skies above earth for nearly 16 years. Named after the renowned astronomer Edwin Hubble, it has brought us some of the most majestic and spectacular photos the human eye has ever seen. Images of our own blue globe to photographs of far flung galaxies and stars have captured the imagination of an entire generation.
We've never seen anything as spectacular and informative as this Interactive Sky Map from the Chandra X-ray Observatory. Since its launch on July 23, 1999, the Chandra X-ray Observatory has been NASA's flagship mission for X-ray astronomy, taking its place in the fleet of "Great Observatories."
The map is just dazzling, and it's easy to navigate the universe. Just click on a colored diamond and you're transported into another visual world along with concise descriptions -everything from the "Rivers of Gravity that Define the Cosmic Landscape" to "Astronomers Take the Measure of Dark Matter in the Universe." The Chandra Map's galactic navigation includes galaxies, galaxy clusters balck holes, normal stars, star clusters, white dwarfs.
