From the BBC this morning:
Astronomers have found a large object in the Solar System's outer reaches. It is being hailed as "a great discovery".
Details of the object are still sketchy. It never comes closer to the Sun than Neptune and spends most of its time much further out than Pluto.
It is one of the largest objects ever found in the outer Solar System and is almost certainly made of ice and rock.
And
A giant patch of frozen water has been pictured nestled within an unnamed impact crater on Mars.
The photographs were taken by the High Resolution Stereo Camera on board Mars Express, the European Space Agency probe which is exploring the planet.
The ice disc is located on Vastitas Borealis, a broad plain that covers much of Mars' far northern latitudes.
