1. When cuckoos lay eggs in other birds’ nests, they produce eggs similar in color and pattern to the hosts’ own. With the help of a new computer program, scientists analyze egg patterns to see how certain details could help host birds detect an imposter.

  2. This month's Astro News features a roundup of Mars stories:

    • A high-resolution map of Mars’s surface shows geologic structures in more detail than ever before.

    • Two missions—MOM and MAVEN—made orbit around the Red Planet.

    • 900 images are assembled to create a billion-pixel panorama of Gale Crater.

  3. On November 12, 2014, more than a decade after launching, the European Space Agency’s Rosetta mission was positioned to send a probe to the surface of 67P/Churyumov–Gerasimenko, a small comet orbiting the Sun at a distance of hundreds of millions of kilometers. After a tense 7-hour descent (and a 30-minute transmission delay), mission control confirmed that the Philae probe had reached the comet’s surface.

    But Philae could not anchor itself; its harpoons failed to deploy. It ‘bounced’ twice on 67P, finally coming to rest in shadow, where it would be unable to fully recharge once its battery ran out. Rosetta mission scientists raced against time to gather as much data as they could. On November 14 at 7:36 p.m. EST (0036 GMT), Philae went silent, possibly for good.

    Philae lander manager Stephan Ulamec of DLR German Aerospace Agency, said: "Despite the unplanned series of three touchdowns, all of our instruments could be operated and now it's time to see what we've got."

    Comets are time capsules dating back to the earliest days of our solar system, and the data gathered by this mission will help scientists understand the forces that shaped the planets, and may reveal the role played by comets in delivering water and organic molecules to an infant Earth.

  4. Wildfires, whether ignited by lightning or people, show global patterns that are visible to satellites. In the United States, fire is increasing: on average, millions more acres burn each year than was typical a few decades ago, and fire season is longer. Prolonged drought in the West, provoked by climate change, is encouraging this rise in fire.
