Is there life on Mars?NASA’s Curiosity rover found what the New York Times calls “startlingly high amounts of methane in the Martian air” last week. As the Times explains, this type of gas on Earth is “usually produced by living things.”
The mission’s controllers sent new instructions to the rover to follow up on the readings. When the results came back yesterday, the methane spike had disappeared.
In addition, a glowing object was photographed hovering just above the surface of Mars earlier this month. Whatever it was, it seemed to be moving quickly.
However, NASA notes that such images are seen nearly every week and “can be caused by cosmic-ray hits or sunlight glinting from rock surfaces.” And methane gas can be produced by geological forces that have no connection to biological life. |
