The massive planet 2M1207b is four times the mass of ******* and orbits a brown dwarf (of course named 2M1207). Using the near infrared camera (Wide Field Camera 3 or WFC3) on Hubble Space Telescope, scientists measured the rotation of this cloudy planet through direct imaging. This is the first time such a measurement has been done. The clouds are patchy but colorless and probably contain silicates (vaporized rock). The atmosphere is very hot, around 2400 degrees F (1315 C).
It may cool down to be more hospitable, but not too soon!
We’ll have the live-chat turned on for this event, so feel free to talk with one another and ask questions for the panelists!
On top of that, we’ll be live-tweeting the event using the hash tag #HubbleHangout, so make sure you give us a follow on Twitter at http://twitter.com/HubbleTelescope
