Hubble Finds That the Nearest Quasar Is Powered by a Double Black Hole
Quasars are the light fantastic. These brilliant cores of active galaxies blaze with the radiance of a hundred billion stars compressed into a region of space not much larger than our solar system. Supermassive black holes, with millions or billions of times the mass of our sun, are the only imaginable powerhouse behind these tsunamis of raw energy.

NASA begins year-long 'Mars isolation' experiment
A crew testing how a small group of humans might cope with a trip to Mars has started their 12-month mission. They will have to eat, communicate, and live exactly as they would on Mars - in a tiny dome in Hawaii.

NASA Chief to Congress: 'Don't Make Us Hitch Rides With Russia'
NASA Administrator Charles Bolden is tired of relying on the Russians to carry American astronauts into space. Currently, the United States pays for spots on Russia's Soyuz spacecraft, which carry people and supplies to the International Space Station (ISS) orbiting Earth. The White House decided to retire the Space Shuttle in 2004 after the Columbia disaster, leading to the final launch in 2011.

1 graphic that shows how we are all related
Scientists have released a new version of the tree of life, showing everything we know about how the living things of Earth are related to one another. With 2.3 million species and counting, it's the most complete model of its kind - but there's a lot more work to do. Everything that lives or ever lived on Earth is somehow related to everything else. But figuring out just how all those critters and plants and pond scums fit together has posed a bit of a challenge.

Elon Musk's Plans for Sending 1 Million People to Mars for $500,000 Each.
Elon Musk has long been a vocal proponent for the quest to send humans to Mars, regularly suggesting that humanity must become interplanetary if it is to survive. In the past, Musk has claimed that the human race has the potential to evolve to an almost god-like level, but has also argued that if we limit ourselves to just one planetary realm, we may not survive long enough to reach our potential.

Exploding star 20 times bigger than Sun captured by Hubble
The expanding remains of a supernova 20 times bigger than the Sun have been caught on camera. Nasa has released images and video of the Veil Nebula, which is debris from a massive star explosion 8,000 years ago, captured by the Hubble space telescope. The nebula resembles a crumpled bed sheet viewed from the side. Ashley Morrow, of Nasa

Nasa scientists find evidence of flowing water on Mars
Rather than being a bone-dry place, it turns out that there is water ice on the moon. It's in small amounts -- think worse than a desert -- but it is there. A key question now is whether the ice would be enough to support a lunar colony. Earlier this year, LRO found that hydrogen (an indicator of water) appears to be more abundant on pole-facing slopes in the studied region, which was the southern hemisphere. These maps will be key in indicating locations for future human outposts.

Gorgeous new images of Charon reveal a violent past for Pluto’s moon
Pluto's largest moon Charon is proving to be a magnificent world in its own right. The latest images from NASA's New Horizons flyby mission -- the highest resolution color images of Charon to date -- show a moon much more alive than our own. “We thought the probability of seeing such interesting features on this satellite of a world at the far edge of our solar system was low,” Ross Beyer, an affiliate of the New Horizons Geology...
