Tuning In to Other Worlds
|
| Topic: New Planets |
09/04/02 |
| Some scientists think it may be possible to detect planets beyond our solar system by looking for radio signals generated by same forces that lead to 'Northern Lights'. A team of scientists working on a radio telescope called the Low Frequency Array (LOFAR) plan to do just that, by trying to tune in to other worlds. |
