This morning, NASA's NuSTAR telescope was launched into the low-Earth orbit from which it will begin exploring the high-energy X-ray universe to uncover the secrets of black holes, the dense remnants of dead stars, energetic cosmic explosions, and even our very own sun.
Today's Earth Week feature highlights three cross-disciplinary research centers where Caltech scientists and engineers collaborate on projects that will have a positive impact on energy, the environment, and Earth's sustainable future.
Caltech joins the world in celebrating Earth Week, April 21–25, 2014, with events, news, and features highlighting our past, present, and future contributions to a healthier, cleaner, and greener planet.
Number theorists are particularly interested in prime numbers (those integers that cannot be divided by any number other than itself and 1) and Diophantine equations. Diophantine equations are polynomial equations (those with two or more variables) in which the coefficients are all integers. It is these equations that are the inspiration for a recent proof offered by Dinakar Ramakrishnan, Caltech's Taussky-Todd-Lonergan Professor of Mathematics and executive officer for mathematics, and his coauthor, Mladen Dimitrov, formerly an Olga Taussky and John Todd Instructor in Mathematics at Caltech and now professor of mathematics at the University of Lille in France. What Ramakrishnan and Dimitrov showed is that a specific collection of systems of homogeneous equations with six variables has only a finite number of rational solutions (up to scaling).

On Monday, March 17, 2014, collaborators working with the BICEP2 telescope at the South Pole presented the world with its first direct evidence of primordial gravitational waves and thus of cosmic inflation. Caltech professor of physics Jamie Bock, co–principal investigator for BICEP2 and the chief architect of the telescope's detectors, described the finding as "mind-boggling."
