那颗谎报自转速度的行星

一项新研究指出，天文学家在测量遥远系外行星的自转时，可能误将大气风速当作了行星自转速度。研究者建议利用多波段观测来修正这一偏差，这对未来柏拉图卫星（PLATO）的任务至关重要。

A new study warns that astronomers measuring the rotation of distant exoplanets may often be measuring atmospheric winds instead, since the clouds of Venus circle the planet roughly 60 times faster than Venus itself actually spins. Kane proposes using multi-wavelength observations to correct for this, work that will matter enormously once the European Space Agency's PLATO mission launches in 2027 and, researchers predict, discovers several hundred Venus like exoplanets.
