Amazingly, a single day on Venus is longer than its entire year. It takes Venus 243 Earth days to completely rotate on its axis, but just 225 days to orbit the sun. Stranger still, Venus is one of two planets that rotates in reverse, a phenomenon called retrograde motion. Most theories attribute the reverse rotation to an ancient planetary collision.
Astronomers have spotted a "rogue planet" - wandering the cosmos without a star to orbit - 100 light-years away. Recent finds of such planets have suggested that they may be common, but candidates have eluded close study. The proximity of the new rogue planet has allowed astronomers to guess its age: a comparatively young 50-120 million years old. The planet, dubbed CFBDSIR2149-0403, is outlined in a paper posted online to appear in Astronomy and Astrophysics.
Remix Nebula ...So what is a nebula? It is a cloud of dust, hydrogen, helium and other gases that attract matter and materials to clump. These so called clumps form stars, planets, and other planetary systems. In simple, Nebulae are where the stars are formed! (Wikipedia)
For the first time ever, we have a complete picture of the planet Mercury. Scientists used thousands of images captured over a period of years to piece together this mesmerizing 360 degree view of the planet.
The Spirograph Nebula - Glowing like a multi-faceted jewel, the planetary nebula IC 418 lies about 2,000 light-years from Earth in the constellation Lepus. In this picture, the Hubble telescope reveals some remarkable textures weaving through the nebula.
