The mysterious nature of dark matter has always been a point of contention for some scientists. However, a recent simulation using one of the world's most powerful supercomputers has created a mockup of dark matter clumps possibly existing in the inner regions of the Milky Way. Find out more about this dark matter puzzle in our full article after the jump.

The Earth is old. Far older than we can imagine. It has a history of life we've only glimpsed here and there from fossil records and other clues. It was here long before we came, and will be here long after we're gone. There's no better reminder of this than seeing how vulnerable life on the planet really is. This week's Science Weekend Warrior is all about appreciating life on Earth.

The fate of the world is in the stars. Literally. Scientists believe galactic motion of the Milky Way is the cause of the rise and fall of species in the Earth. Darwin needs to rework his theory. Details in the full article.

Supermassive black holes are so colossal that they are thought to be the center of most galaxies, including our own. Tearing through spacetime, these enormous entities pose a giant question: how do they feed? Scientists may have found a clue. Details in the full article.

Is there such a thing as a killer meteor season for the Earth? Scientists believe so. One theory says that the killer meteor that killed the dinos came during this kind of season. Scientists now believe we are close to another such season. More details in the full article.

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.

In just about every galaxy known to man, the most common feature in them is that they all have a monstrous centerpiece: a massive black hole. For some reason, Milky Way's own Sagittarius A* seems dormant, but Japanese observers say it wasn't always this way. The full story follows after the jump.

Though black holes are often characterized as humongous gravity sinks, scientists believe there's a minimum mass requirement for any black hole in existence. They've got the requirements down pat by way of theoretical prediction only, but two able researchers from NASA finally pinpointed the smallest black hole to date. It could help them judge whether their estimates are accurate enough. More details at the full story.

A recent study has confirmed that there are hundreds of other planets which carry conditions similar to Earth in the outskirts of the Solar System and even across the Milky Way Galaxy.

The scientists hope to know more about this in the continued search for life and possible future colonies. Know more after the jump!

A star nine times the size of our own Sun has been observed speeding away from our Milky Way at 1.6 million miles per hour. While this may not be an unusual event in and of itself (stranger stuff have happened in the universe - game delays for instance), scientists have been puzzled by the star's origins since it didn't come from our own galaxy. Now they believe that the star came from another galaxy, catapulted away by a black hole 1,000 times the mass of the Sun. Details in the full article.
