NASA’s Phoenix Mars Lander won’t attempt that final precarious 7 minute descent until 25th May.. so expect more coverage as that date approaches. Meanwhile you could spend some time exploring the universe with the wondrous Microsoft Worldwide Telescope. The Guardian’s Jack Schofield has some useful background – it made Robert Scoble cry – although Jack’s Guardian colleague can’t get past his Mac fixation.. ANYhoo.. the Guided Tours are magnificent – the image is from the tour of the Centre of the Milky Way and is a radio-wave view, taken by the Very Large Array Telescope, of Sagittarius A, within which likely lurks a super-massive blackhole at the Galactic Centre, surrounded by supernova remnant shells and filaments created by magnetic fields. NASA seem happy too. Some FAQs here. What would Galileo say?..
