Bush: Human Beings are Heading Into the Cosmos.
As predicted for several months, US President George W. Bush announced his plan for the future human exploration of space. Bush was joined by NASA administrator Sean O'Keefe and the press briefing was introduced by the commander of Expedition 8, Michael Foale - currently aboard the International Space Station.
Spitzer space telescope Image of the Tarantula Nebula.
The latest image from the Spitzer space telescope is of often-photographed Tarantula Nebula. Spitzer, however, is able to pierce through the dust and material that surrounds the nebula to take a good look inside this active star-forming region. This new photograph has turned up previously hidden stars inside the nebula, as well as empty cavities of space around them - their powerful radiation blows all the dust away. Images like this will help Astronomers understand the environments that form stars and get a better sense of where our own solar system came from.
Star Mimics a Black Hole.
Astronomers using the Australia telescope Compact Array have found a rapidly spinning neutron star which is spitting out jets of material at nearly the speed of light. Jets like this have only been seen previously coming out of black holes, and this discovery challenges the theory that only the environment around a black hole can be so energetic. The Astronomers studied Circinus X-1, an object located about 20,000 light years away, which is a bright source of X-rays. They know it's a Neutron star, but it also has these unusual characteristics.
Martian surface - First a Crater, then Head for the Hills.
NASA's Spirit rover has completed its pivoting maneuver atop its landing platform, and it's nearly ready to roll out onto the Martian surface. Mission scientists have decided that the rover's first target will be a relatively nearby 200-metre wide impact crater, which is approximately 250 metres northeast of the landing site. A crater like this is a convenient hole in the ground which allows the rover to look back into Martian history to see if there are sedimentary layers; a sure indication that there was standing water in the past. After studying the crater, Spirit will make for a set of hills approximately 3 kilometres away; although, that could be outside its range.
