Hubble Measures Rotation of ‘Super-Jupiter’ Exoplanet 2M1207b

Using the Hubble Space Telescope, a team of astronomers has measured the rotation rate of an extreme exoplanet by observing the varied brightness in its atmosphere. This is the first measurement of the rotation of a massive exoplanet using direct imaging. “The result is very exciting,” said Daniel Apai of the University of Arizona in […]
