The fingerprint of a cosmos swirling with gravitational waves Recent data from pulsar-timing array experiments are consistent with the Hellings–Downs curve, a unique signature of gravitational radiation. Sarah Vigeland and Stephen Taylor Nearby star hosts a half-dozen synchronized sub-Neptunes The system's planets are in resonant orbits, suggesting that they have enjoyed a relatively quiescent existence. Andrew Grant FROM THE VAULT: October 1948 The origin of the Earth Pouring the evidence of many kinds of science into a single pot to answer this question, the author, an astrophysicist, finds that one is pushed successively from speculating on the origin of the earth to speculating on the origin of the solar system, the origin of stars, of nebulae, of galaxies, of the universe—on to the beginning of time. Thornton Page Webinar Back by Popular Demand: Webinar on Selecting a Laser for Raman Spectroscopy In the webinar we discuss which laser specifications are important to fully understand and appreciate when embarking on Raman spectroscopy based research.
