Scanning the heavens, you might very well miss the star Kepler-62. It's a rather typical star, slightly smaller, cooler, and more orange than the Sun, much like tens of billions of other stars in our galaxy. But it holds a surprise: It's orbited by at least five planets… and two of them are Earth-sized and orbit the star in its habitable zone!
These are the photographs and journal of George Murray Levick, who traveled with Captain Robert Falcon Scott (greatest name ever) on the ill-fated south pole expedition.
Levick was one of six men in Scott's Northern Party, who summered (1911-1912) at Cape Adare and survived the winter of 1912 in a snow cave when their ship was unable to reach them. Levick was not part of the team that accompanied Scott on his doomed quest to be the first to reach the South Pole.
After an arduous two-and-a-half month trek, Scott and his crew did make it to the South Pole on Jan. 17, 1912. But they discovered that the Norwegian explorer Roald Amundsen had beat them to it. Scott and his team died on the way back to their base, faced with a blizzard and dwindling supplies.
Physicists Nima Arkani-Hamed and Jaroslav Trnka recently published a significant advance in the study of Scattering Amplitudes. These are formulas that physicists use to calculate everything from the chance an unstable particle will decay to the probability of new discoveries at the Large Hadron Collider. The two reformulated scattering amplitudes within a popular framework called N=4 super Yang-Mills, treating them as properties of abstract geometrical objects. In doing so, Arkani-Hamed and Trnka hope to gain a deeper understanding of the nature of quantum field theory.
