Just as an expert chess player sacrifices a piece to protect the queen, the solar system may have given up a giant planet and spared the Earth, according to an article recently published in The Astrophysical Journal Letters.
While looking for a safe place to weather the cold Martian winter, the rover Opportunity spied something protruding from the Mars regolith -- something it's never seen before.
Astronomers have measured the diameter of the dwarf planet Eris by catching it as it passed in front of a faint star. This was seen by telescopes in Chile, including the TRAPPIST telescope at the European Southern Observatory
The "fifth planet" is a hypothesized giant world that was flung out of our solar system 4 billion years ago.

A team of scientists has discovered a new mineral -- krotite, one of the earliest minerals formed in our solar system. It is the main component of an unusual inclusion embedded in a meteorite (NWA 1934), found in northwest Africa. These objects, known as refractory inclusions, are thought to be the first planetary materials formed in our solar system, dating back to before the formation of Earth and the other planets.
The Asteroid 2005 YU55, about 1,300 feet in diameter, will approach Earth within 0.85 lunar distances in early November 2011. Discovered on December 28,
Scientists have isolated and resolved the mysterious
Are we all Martians?
The vision of a joint US and European mission to Mars faces a radical rethink as the US admits its funding will come up $1bn short.
Planets form in disks of dust and gas that surround young stars. A look at the birth places means a journey into the past of Earth and its siblings. Now, astronomers have been able to obtain detailed images of the protoplanetary disks of two stars using the Subaru telescope in Hawaii.
