New Horizons is Approaching Pluto. Here’s How Very, Very, Far Away Pluto Is 

Dan\'s Wild Wild Science Journal [2015-03-26 00:11:05]  recommend  recommend this post  (231 visits) info
Most folks are surprised to know that we have no idea what the surface of Pluto looks like. Even using the Hubble Telescope, we only see a bright star like image, but that is about to change this summer when the New Horizon’s spacecraft flies by it. We are sure to see some strange features on both Pluto and it’s moons. Would you like to help name them? I’ll tell

Capturing Cassini – 10 years of Saturnian science on camera

This year marks the 10th anniversary of the Cassini-Huygens mission to study Saturn and its moons. But what’s 10 years to us is only a fraction of the Saturnian calendar – in the decade we’ve been studying Saturn up close, the planet has only been through a third of its annual cycle. In that short

A New Moon Forming in the Rings of Saturn?

Futurelearn is a network of UK universities offering free online courses, and there is one coming up on Moons starting on 17th March, for 8 weeks - they estimate about 3 hours of study a week. Each week a series of lectures and/or articles is put up on the web, and you can access as and when you choose.  There is a quiz at the end, but there is no requirement to do this - or indeed to do any parts that don't interest you.

The joint NASA-ESA Cassini space probe, exploring Saturn and her moons, has revealed extraordinary lakes and seas of liquid methane around the north pole of Titan. Scientists associated with the Cassini mission described a strange rectangular area of large seas, picked out by imaging instruments aboard the probe. I heard all about it at the

Europa Might Have Had an Axial Tilt (and lost it)

By analyzing the distinctive cracks lining the icy face of Europa, NASA scientists found evidence that this moon of Jupiter likely spun around a tilted axis at some point. This tilt could influence calculations of how much of Europa's history is recorded in its frozen shell, how much heat is generated by tides in its ocean, and even how long the ocean has been liquid.
