New roadmap to finding and assessing Earth-like exoplanets for habitability

Press release about the NASA-NSF Extreme Precision Radial Velocity Working Group’s final report, making recommendations for a pathway to achieve Earth analog detections using EPRV.

New technique could elucidate earliest stages of planet’s life

Press release about the PFS observations showing the orbit of a transiting planet around the 45 Myr old star, DS Tuc A, is well-aligned (Zhou et al. 2020, Montet et al. 2020)

Gas giant composition not determined by host star

Press release about Teske et al. (2019), in which we measured the compositions of stars that host cool, giant planets, and found a surprising result that we think is related to giant planet formation!

TESS mission helps uncover trio of planets with one possibly habitable world

Press release about an exciting new three-planet system, which was hiding like buried treasure in our radial velocity data but needed TESS data to help confirm.

TESS finds its first Earth-sized planet

Signs of a ‘super Earth’ discovered around a nearby star

Press release about a small planet detected around Barnard's star, the second closest star (and closest single star system) to our own.

Rocky planet neighbor looks familiar, but is not Earth’s twin

Press release about the composition of exoplanet host star Ross 128, and what it might imply for the composition of the orbiting rocky planet.
