There's some sad news from NASA: The space agency says its Kepler space telescope is beyond repair.
The $600 million planet-hunting probe whose mission was to search other solar systems for Earth-like planets has lost its ability to keep its gaze on target.
Two of the four gyroscope-like reaction wheels that keep Kepler pointed in the right direction have broken down and can't be fixed, but NASA is still hoping it can find some less-stressful work for the orbiting observatory.
Oklahoma was hit particularly hard by two massive outbreaks this year in what's been another deadly season of tornadoes in the U.S. Despite technology and forecasting improvements, scientists still have plenty to learn about how and why tornadoes form.
Currently, one of the best ways for researchers to understand how tornadoes form is to chase them. So off they go with mobile science laboratories, rushing toward storms armed with research equipment and weather-sensing probes.
Scientists have just solved a case of mistaken identity. It involves a creature that looks like a cross between a house cat and a teddy bear, and it lives high up in the cloud forests of the Andes.
For over 100 years, scientists thought this animal was a well-known member of the raccoon family. Specifically, they thought it was a critter called the "olingo." But one scientist recently took another look and realized he had an entirely new species on his hands.
