We usually name things after their defining characteristics, such as color. There are exceptions, though. One such exception may be the so-called black hole, which Stephen Hawking theorized as not really being black at all. In fact, professors Ulf Leonhardt and Dr Germain Rousseaux used water to test Hawking's theory. Find out the specifics in the full article after the jump.

Where were you last Tuesday, May 6, just after sunset? If you had swept your binoculars' view across the western horizon at the time, you may have noticed an interesting sight - a "meeting" of celestial bodies. That's right, the planet Mercury and our moon seemed pretty much intertwined. More about the phenomenon in the full article after the jump.

Some of the other planets in the solar system have several moons, while the Earth only has one. If you envy other planets because of this fact, then here's something that may soothe your anxiety: the Earth may have had several other moons in the past. Hit the full article to find out exactly why.

With the vast size of our galaxies, it's easy to get lost in such a massive space, it seems that mini-galaxies have gone missing. Scientists are now wondering where all the mini-galaxies have gone. Have they just disappeared completely? Or have they merged with other galaxies? Details in the full article.

Have you ever wondered what goes on on the inside of a black hole? Wonder no more, as researchers at the National Science Foundation have an idea of the kind of action that takes place within this cosmic phenomenon. It can probably be summed up in one word: corkscrew. More cosmic fury escalates in the full article after the jump.

Few would argue that there are lots of beautiful sights to see in outer space. In fact, one such cosmic wonder is known as the Fox Fur Nebula, which was viewed through the Canada-France-Hawaii Telescope (CFHT). Check out the nebula in the full article, after the jump, why don't you?

Don't you love it when things go boom? So would some astronomers, it would seem, as a recent entry in the latest issue of The Astrophysical Journal reflected much of their excitement. You see, a supernova went nuclear some 1,600 centuries ago in a collection of nebulae called the Large Magellanic Cloud, but even now the after effects of the collapse was readily observed. How is that possible? Prepare for another crash lesson on physics and time at the full story.

Dark matter on Earth? Scientists participating in the Dark Matter (DAMA) Project drew results that could be indicating the presence dark matter - results that mimicked those discovered five years ago. And guess what? The Italian scientists detected the activity 1.4 kilometers deep inside the mountain of Gran Sasso in Italy, where the DAMA observatory resides. Get more at the full story.

The question of how the universe came to be is a common one now, and the Big Bang theory does a good job of giving us clues on what actually happened. However, has anyone stopped to think what there was before the huge explosion of matter? Scientists have, and they say there could very well have been a twin universe to ours before this one came to be. Details in the full article.

Space may not be the final frontier just yet since we still have quite a few mysteries here on Earth, but it does have its own share of unexplained phenomena. One of these mysteries is the neutron star; the remains of a collapsed star. NASA is currently observing what may be a neutron star evolving before their very eyes. Details in the full article.
