A new cosmic survey offers unprecedented view of galaxies

By the Office of the Dean for Research The universe has come into sharper focus with the release this week of new images from one of the largest telescopes in the world. A multinational collaboration led by the National Astronomical Observatory of Japan that includes Princeton University scientists has published a "cosmic census" of a … Continue reading A new cosmic survey offers unprecedented view of galaxies

An explanation for the mysterious onset of a universal process (Physics of Plasmas)

By John Greenwald, Princeton Plasma Physics Laboratory Communications Scientists have proposed a groundbreaking solution to a mystery that has puzzled physicists for decades. At issue is how magnetic reconnection, a universal process that sets off solar flares, northern lights and cosmic gamma-ray bursts, occurs so much faster than theory says should be possible. The answer, … Continue reading An explanation for the mysterious onset of a universal process (Physics of Plasmas)

European satellite could discover thousands of planets in Earth’s galaxy (arXiv)

By Morgan Kelly, Office of Communications A recently launched European satellite could reveal tens of thousands of new planets within the next few years, and provide scientists with a far better understanding of the number, variety and distribution of planets in our galaxy, according to research published today. Researchers from Princeton University and Lund University … Continue reading European satellite could discover thousands of planets in Earth’s galaxy (arXiv)

Rife with hype, exoplanet study needs patience and refinement (PNAS)

By Morgan Kelly, Office of Communications Imagine someone spent months researching new cities to call home using low-resolution images of unidentified skylines. The pictures were taken from several miles away with a camera intended for portraits, and at sunset. From these fuzzy snapshots, that person claims to know the city's air quality, the appearance of … Continue reading Rife with hype, exoplanet study needs patience and refinement (PNAS)

Shape from sound — new methods to probe the universe (Physical Review Letters)

By Morgan Kelly, Office of Communications As the universe expands, it is continually subjected to energy shifts, or "quantum fluctuations," that send out little pulses of "sound" into the fabric of spacetime. In fact, the universe is thought to have sprung from just such an energy shift. A recent paper in the journal Physical Review … Continue reading Shape from sound — new methods to probe the universe (Physical Review Letters)
