Astronauts chat in Google+ Hangout

NASA hosted its first Google+ Hangout with astronauts on the International Space Station, allowing Earthly onlookers to ask questions by video.

Astronauts Kevin Ford, Chris Hadfield and Tom Marshburn answered questions, such as how they prepare for medical emergencies.

The answer is that they have on-board medical kits with everything from aspirin to an IV to a defibrillator. But if there were a real problem with one of the crew members, the Soyuz shuttle would act as an ambulance, they said.

The clip above shows the part of the video chat about dealing with medical problems. NASA also posted the full conversation, lasting more than an hour, on YouTube:

Peter Gabriel hears his song played from the International Space Station

British singer Peter Gabriel got a brief serenade from a member of the International Space Station crew on Wednesday during a visit to Mission Control in Houston.

Canadian Chris Hadfield, Expedition 34's flight engineer, strummed a few chords of Gabriel's hit "In Your Eyes" during a nearly 12-minute chat with Gabriel and his family.

Hadfield told Gabriel that he recorded two songs in space. The first, co-written with his brother, is a "space Christmas carol" called "Jewel in the Night." The second, a space-to-Earth collaboration with Canadian band Barenaked Ladies, is called "I.S.S. (Is Somebody Singing)."

Click on the video above to hear Hadfield's performance.

How to kill a killer asteroid

By Nova Safo, CNN

Follow on Twitter: @nova_safo 

The meteor that wreaked havoc in Russia last week, shattering windows around a 50-acre area and injuring 1,200 people, was not as big as the asteroids that Dr. Bong Wie of Iowa State University is worried about. He is researching how to stop one of the 400 asteroids scientists have discovered, which have some chance of crashing into Earth and potentially destroying a city.

Wie has gotten NASA’s attention with a plan that seems right out of the Hollywood blockbuster "Armageddon." He is working on a plan to bury a nuclear bomb into a potentially deadly asteroid and blow it up into tiny pieces.

Science Seat: Meet a climate change scientist

By Zaina Adamu, CNN

Editor's note: The Science Seat is a feature in which CNN Light Years sits down with movers and shakers from many different areas of scientific exploration. This is the third installment.

Thousands of families were left devastated when Superstorm Sandy destroyed their homes in October. When it comes to these extreme climate events, according to Chris Field, founding director of the Carnegie Institution's Department of Global Ecology, the worst is yet to come.

Field is also a professor of biology and environmental earth system science at Stanford University and a member of the Intergovernmental Panel of Climate Change delegation that won the 2007 Nobel Peace Prize. He holds a doctorate from Stanford University.

CNN Light Years spoke with Field before he headed to Boston for the recent American Association for the Advancement of Science conference. Here is a transcript, edited for brevity and clarity:
