Proposed ‘geophysical definition’ re-instates Pluto as a planet — and adds 100 new ones in the Solar System

I never lost faith in you, Pluto.

Scientists find new dwarf planet in our solar system

Astronomers have found a cosmic friend for Pluto.

New dwarf planet discovered in outskirts of solar system beyond Neptune

Pluto and Ceres have a new neighbor.

Welcome back to the family, Pluto!

Before you get overly excited, no, Pluto hasn’t been once again accepted as a planet – it’s still officially a dwarf planet (though in our hearts, you’ll always be a planet, Pluto!). However, this emblematic picture of the solar system from my childhood is now complete, as seen in this great family portrait produced by Ben Gross, a research fellow at the Chemical Heritage Foundation. Basically, we have at least the one good image of all the worlds in our solar system.

NASA’s New Horizons spacecraft set for historic rendez-vous with Pluto

NASA’s New Horizons spacecraft has officially begun its six month approach to the planet Pluto. This is the first time a human shuttle will flyby the icy dwarf planet.

Hints of water found on the giant space rock Vesta

Two studies conducted by scientists at NASA based on data gathered by the Dawn spacecraft, which orbited around the Vesta asteroid, showed that the giant space rock holds tantalizing signs of water on its surface – albeit in very small amounts, in the form of hydrated minerals. These conclusions were drawn after scientists found that volatile, or easily evaporated materials, have colored Vesta’s

Pluto gets a new moonand still isn’t a planet

All eyes seem to be pointed on Jupiter and Mars these days, with NASA probes being planned for both of them, and it’s easy to forget that there’s a spacecraft currently heading towards the edge of the solar system, aimed straight at Pluto at a speed of 80,000 kilometers per hour. Even at this speed though, it will still take

Rugby-ball shaped dwarf planet covered in crystalline water ice

Discovered deep in the farthest reaches of our solar system, Haumea is a tiny dwarf planet which has been fascinating scientists for years now since its discovery in 2004, not only because of its peculiar rugby-ball shaped form, but also because of its surface structure. According to the European Southern Observatory, 75 per cent of its surface is covered with
