This wider view of Uranus reveals the planet's faint rings and several of its satellites. The area outside Uranus was enhanced in brightness to the faint rings and moons. The outermost ring is brighter on the lower side, where it is wider. It is made of dust and small pebbles, which create a thin, dark, and almost vertical line across the right side of Uranus (especially visible on the natural-color image).
Three astronomers will share the Nobel prize in physics, for their finding that the universe's post-Big Bang expansion is neither slowing nor retreating, but is speeding up.
Astronomers are on the cusp of new discoveries in the search for distant planets that could have life. But budget cuts are forcing this branch of space exploration to turn to smaller, less-ambitious projects.
