A first for a planet far, far away
Astronomers have for the first time managed to determine the color of a planet outside our solar system — a blue gas giant 63 light-years away. Using the Hubble Space Telescope, an international team said the planet known as HD 189733B would look like a deep blue dot if viewed up close. "Measuring the planet's color is a real first — we have never managed it before with a planet outside our own solar system," Frederic Pont of the University of Exeter in England said Friday. Discovered in 2005, the planet belongs to a class of giant gas planets called "hot Jupiters" that orbit close to their stars.
Ruling stands: Firing not bias
A dentist acted legally when he fired an assistant because he had grown too attracted to her and worried he would try to start an extramarital affair, the Iowa Supreme Court reaffirmed Friday in its second crack at the controversial case. Coming to the same outcome as it did in December, but clarifying its rationale, the court found that bosses can fire employees that they and their spouses see as threats to their marriages. The court said such firings do not count as sex discrimination because they're motivated by feelings, not gender. The ruling upholds the dismissal of a discrimination lawsuit filed by Melissa Nelson against James Knight of Fort Dodge. The married mother of two had worked for Knight for 10 years.
