Carnival of Space #350

Carnival of SpaceIt may be a public holiday here in sunny South Africa, but the Carnival of Space never sleeps. This week's host is Nicole Gugliucci and she presents the 350th Carnival of Space on the CosmoquestX Blog.  Every week the Carnival moves to a new host, who must sift through the past week's space science and astronomy writing and choose the very best.  If you'd like to see your work featured, why not drop a mail to carnivalofspace@gmail.com? Just let us know who you are and what you'd like to submit. Read more about Carnival of Space #350

Roth/SWRI/University of CologneAstronomers using the Hubble Space Telescope have discovered what appear to be enormous seasonal jets of water vapour venting from Europa - one of the four large moons of Jupiter that are visible from Earth through simple binoculars. If these observations can be confirmed, then Europa will be only the third world known to have water geysers, after Earth, and Saturn's moon Enceladus. The jet of water vapour appears to shoot up to a height of over two hundred kilometers before falling back down to the icy moon's surface, and only vents at certain points in its orbit around Jupiter.  Researchers are now trying to confirm if they have found a real phenomenon, and that it is indeed a jet of water coming from the surface of Jupiter's satelliteRead more about Hundred mile high water geyser detected on Jupiter's moon

Weather forecasts beyond the Solar system

Bacon (STScI)For the first time, astronomers are able to make weather predictions on distant planets orbiting stars other than our own Sun.  For two worlds whose atmospheres scientists have been studying, the forecast is overcast, with a chance of additional cloud. The planets, GJ 436b, and GJ 1214b, are 36 light years away in the constellation Leo, and 40 light years away in the constellation Ophiuchis, respectively.
