Mystery of missing exoplanet water solved using NASA space telescopes

14 December 2015 Astronomy Now

A survey of ten hot, Jupiter-sized exoplanets conducted with NASA’s Hubble and Spitzer telescopes has led a UK-US team to solve a long-standing mystery — why some of these worlds seem to have less water than expected. The findings offer new insights into the wide range of planetary atmospheres in our galaxy and how planets are assembled.


5,400mph winds hurtling around exoplanet

14 November 2015 Astronomy Now

Wind speeds of over 2 kilometres per second have been discovered flowing around planet outside of our solar system. The University of Warwick discovery is the first time that a weather system on an exoplanet has been directly measured and mapped. The wind speed recorded is 20x greater than the fastest ever known on Earth, where it would be seven times the speed of sound.
