Okay, I have decided to start a space news topic. Anyone willing to contribute too feel free 
After a couple of weeks I will decide if this topic is still worthy of a sticky.

| Quote: | Massive Black Hole Stumps Researchers
A team of astronomers have found a colossal black hole so ancient, they're not sure how it had enough time to grow to its current size, about 10 billion times the mass of the Sun.
Sitting at the heart of a distant galaxy, the black hole appears to be about 12.7 billion years old, which means it formed just one billion years after the universe began and is one of the oldest supermassive black holes ever known.
The black hole, researchers said, is big enough to hold 1,000 of our own Solar Systems and weighs about as much as all the stars in the Milky Way.
"The universe was awfully young at the time this was formed," said astronomer Roger Romani, a Stanford University associate professor whose team found the object. "It's a bit of a challenge to understand how this black hole got enough mass to reach its size."

| Quote: | Cassini Prepares To Put On The Brakes
The two-story tall Cassini spacecraft is ready to end its long interplanetary voyage and begin a multi-year exploration campaign at that gas giant of a world, Saturn.
�It�s been a long time coming,� said Robert Mitchell, Cassini program manager, at a press briefing held today at the Jet Propulsion Laboratory (JPL) in Pasadena, California.
For Cassini the major action item ahead is putting on the brakes -- set to occur tomorrow at roughly 10:36 p.m. (Eastern Daylight Time). The spacecraft�s engine firing will slow the probe down so it can be captured by Saturn's gravity. That engine burn lasts approximately 96 minutes.
�While we�re all a little bit nervous, we�re also very excited,� Mitchell said. Tomorrow�s Saturn Orbit Insertion, or SOI for short, ranks as a �rather hair-graying� event. �There are no problems. We have no indication of any problem with the spacecraft that would have any adverse impact on SOI.�

| Quote: | Ring Around the Planet: Cassini's First Images of Saturn from Orbit
Hours after entering orbit around Saturn, the international Cassini-Huygens spacecraft has relayed its first images.
The international $3.3 billion mission completed its 96-minute Saturn Orbit Insertion rocket burn at roughly 12:12 a.m. Eastern Daylight Time, early Thursday morning. The successful maneuver sparked applause, handshakes and hugs from flight controllers at the Jet Propulsion Laboratory (JPL) in Pasadena, California.
In reaching its initial orbit, Cassini started an initial four-year odyssey of the giant planet, its majestic rings and family of moons.One by one the raw, unprocessed images from Cassini began to reach JPL mission control.
Close-up photo of Saturn�s ring system started to reveal exciting features, said Carolyn Porco, Cassini imaging team leader from the Space Science Institute in Boulder, Colorado.
�They are just beautiful. They are very sharp,� Porco said. �We�re going to have a field day with these.�
