Saturn's chilly north pole boasts a hot spot of compressed air, a surprising discovery that could shed light on other planets within our own solar system and beyond, researchers said on Thursday.
The space rock in question - Asteroid 2007 WD5 - is similar in size to the object that carved Meteor Crater into northern Arizona some 50,000 years ago and is approaching Mars at about 30,000 miles per hour (48,280 kph).
Whether the asteroid will actually hit Mars or not is still uncertain.
Scientists at the Max Planck Institute for Astronomy in Heidelberg have discovered the youngest known extrasolar planet. Its host star is still surrounded by the disk of gas and dust from which it was only recently born. This discovery allows scientists to draw important conclusions about the timing of planet formation.
How do planetary systems form? How common are they? What is their architecture? How many habitable earth-like planets exist in the Milky Way? In the past decade, astronomers have clearly come closer to finding answers to these exciting questions. With the discovery of the first planet orbiting another Sun-like star in 1995, the field of extrasolar planet research was born.

In addition, the French government said mobile handsets can be bad for children, and Massachusetts law enforcement authorities said a hit-and-run fatality was caused by a man text messaging on his cell phone.

Comment: Let's do something fun. Here's a true/false question.
Are cell phones...
1. Harmful to children
2. Sources of traffic delays
3. Causes of traffic accidents
4. Not really necessary since we've managed without them for ages
5. A reason to put up a cellular infrastructure for potentially nefarious uses
The answer will be revealed when your children get older.
