Science gave us some mighty gifts this past week:
1. We learned about a new, nearby, Earth-like exoplanet in a system NASA describes as being more similar to our own than any other yet discovered.
2. We caught a glimpse of some star-forming dust in infrared.
3. From the Rosetta mission, we got a look inside Imhotep, a region of Comet 67P.
4. The mystery of hair ice, a fungus that grows on dead wood, was solved.
This unusual phenomenon occurs during a perfect storm of rotten wood of high-latitude trees at cool temperatures. They're also elusive, growing primarily at night and melting by morning. The study, published in Biogeosciences, revealed the cobwebby filaments grow with the help of a specific fungus called Exidiopsis effusa (and some mad-cap physics).
5. We discovered a fossilized snake with four legs.
The new find, dubbed Tetrapodophis amplectus, may teach scientists about how lizards evolved into snakes.
