Check out Tvashtar volcano on Io seen spewing molten material into space, as seen from New Horizons probe in 2007. Io experiences massive tidal forces from Jupiter’s gravity and this kind of volcanic eruption is not uncommon for Jovian moons. For a sense of scale, the volcanic plume is about 330 Km in altitude. New Horizon was built by John Hopkins Applied Phyisics Lab for a mission to Pluto. This photo was taken when it flew past Jupiter for a slingshot course correction towards Pluto.

Dance of the Planets 26th Jul 2015
Earlier this month the close conjunction of the two brightest planets Venus & Jupiter was observed all over the world. The planets came so close to each other that they were visible in the field of view of a telescope. The two planets will still be close together as they move into the morning sky, where both will meet-up with Mars later this year.
This Sunday Noon, let’s take a look at how the planets are moving in their orbits and what face and size do they present to the observers on the Earth in the remaining 2015. We will also look at other great observations that you can make this year like the Geminids Meteor Shower, Occultation of Aldebaran by Moon.

Jupiter Venus Conjunction Tonight
Greetings Fellow Earthlings
Tonight step outside the house for a change and look West at sundown. You’ll be greeted with a spectacular planetary pair of Jupiter and Venus almost hugging each other in a nice visual conjunction. Kind of ironical considering Jupiter is God of War, and Venus is the God of Loveeee. This treat will continue for a few days so do not worry if you’re sitting under the clouds right now.
Sky and Telescope astronomy magazine suggested that the event closely resembles the Star of Bethlehem which, according to Christian tradition, revealed the birth of Jesus to the Biblical Magi, and later led them to Bethlehem.
