| Hottest body outside the sun: Io |

The hottest spot in the solar system is neither Mercury, Venus, nor St. Louis in the summer. Io, one of the four satellites that the Italian astronomer Galileo discovered orbiting Jupiter almost 400 years ago, takes that prize. The Voyager spacecraft discovered volcanic activity on Io over 20 years ago and subsequent observations show that Io is the most volcanically active body in the solar system. The Galileo spacecraft, named in honor of the astronomer Galileo, found volcanic hot spots with temperatures as high as 2,910 Fahrenheit (1,610 Celsius). |

| Discovery of a new particle | |||||||||
|
The SELEX collaboration at Fermilab in the US has discovered a new sub-atomic particle that consists of a strange quark and a charm antiquark . In addition to being the heaviest so-called heavy-light meson ever detected, the new particle also decays in ways not predicted by theory. |
