Eris - Dwarf Planet
In a tilted orbit in the scattered disk, it shook up the traditional Solar System. Was it bigger than Pluto, and therefore a planet? No, both of them ended up as dwarf planets. Eris – named for the Greek goddess of discord – was an apt name for an object whose discovery started so many arguments.
Eris – Facts for Kids
At first astronomers thought Eris was bigger than Pluto and that it was a tenth planet. But both Eris and Pluto ended up as dwarf planets. Eris is now farther away from the Sun than any known object except for some comets. It's so cold that its atmosphere has frozen and is on the ground.
Eris and Pluto - They're Not Twins
For nearly ninety years Pluto was our ninth planet. Then in 2006, much to the annoyance of some, it was no longer a planet, but a dwarf planet. What happened? Eris happened. Some call Eris and Pluto twin planets, but they aren't twins. Eris has a secret.

It's great to have access to “the Universe under one roof”. When European Astrofest comes to the Kensington Conference Centre in London, it saves many light years of travel. Here are some highlights of the 2016 event.
Exotic Creatures of the Southern Sky

Exotic Exoplanets Tour
We're used to a tidy Solar System. But there are some pretty strange planets orbiting stars far, far away. On one it doesn't rain water, it rains rock. Another has the density of cork. One has a double sun. And what would you do with a diamond the size of a planet?
Experience the Aurora - film review
Try to imagine seeing the northern lights dancing across the sky above you. A film on a flat screen couldn't duplicate this. But what about one made to be projected on the dome of a digital theater? This was the aim of "Experience the Aurora."

Exploring the Apollo Landing Sites
NASA sent the Lunar Reconnaissance Orbiter (LRO) to the Moon to spy out sites for future manned missions. It doesn't look like they'll be sending anybody to the Moon, but LRO has documented the Apollo landing sites. Astronomy writer and space expert Ian Ridpath takes us to the Moon for a look.
Father Hell - Astronomer
The Moon's Hell crater sounds like the last place a space tourist would ever want to visit. But it's named for 18th century astronomer Father Maximilian Hell, director of the Vienna Observatory. He observed the 1769 Venus transit from Norway's far north, surviving the cold by adopting Sami dress.
