A newfound planet detected by a small, 4-inch-diameter telescope demonstrates that we are at the cusp of a new age of planet discovery. Soon, new worlds may be located at an accelerating pace, bringing the detection of the first Earth-sized world one step closer.

The planet with the second largest number of moons now has two more. The US Cassini spacecraft discovered them around Saturn, bringing the giant ringed planet&#39;s known total to 33.

The Cassini-Huygens spacecraft, a joint project of the US space administration (NASA), the European Space Agency (ESA) and the Italian space agency (ASI), has discovered two more small moons orbiting the planet Saturn, bringing the total to 33.

A tiny telescope has spotted a giant planet circling a faraway star, using a technique that could open a new phase of planetary discovery, scientists say.
708636
Three new planets have been discovered in other solar systems that are the closest ever found to Earth in size, scientists announced today, marking an important step in the search for planets that could support life elsewhere in the universe.

Science judged that the runner-up to the discovery of water on Mars was the finding of another species of dwarf human which lived on the remote Indonesian island of Flores as little as 13,000 years ago.
485749
US astronomers show that wherever there is room for a planet to form around a young star, it does.

Astronomers have discovered the three lightest planets known outside the solar system, moving researchers closer to the goal of finding extrasolar planets that resemble Earth.
26826
A circumstellar disk of dust and gas, the raw material of a solar system, has been found circling the star TW Hydrae.

Space scientists are sending a small package to Titan, one of the moons of Saturn. The package in question is a space probe called Huygens which is due to be separated from its mother ship, Cassini
282539
Astronomers using telescopes not much larger than the spyglass Galileo wielded 400 years ago have discovered a new Jupiter-sized planet orbiting a bright, distant star.
34606
Astronomers discover a newborn planet in a solar system that is still in the process of forming.
420931
Two new moons orbiting between Mimas and Enceladus, discovered by the NASA/ESA/ASI Cassini-Huygens spacecraft, may be the smallest bodies so far seen around the ringed planet.
270802
It is the first planetary system that really looks like our own, with outer giant planets and room for smaller inner planets, astronomers say.

The roll call of planets beyond the solar system swelled significantly with the announcement of a trio of newly discovered worlds much smaller than any previously discovered around other stars.
