Pluto flyby: New Horizons probe makes contact with Earth – live | Science | The Guardian.

london 6.08am wednesday 2015

a running update in real time of the pluto flypass. it seems it is the only time any of us living now can see a new planet up close. put that way it is quite exciting. and this one is not obscured by atmosphere. (which kinds of justify its status as a planet being downgraded.) i think that a planet by definition should have a atmosphere.

added.16.7.15 5.20am. Pluto sometimes has an atmosphere:
During Pluto’s elliptical when Pluto is closer to the Sun its surface ice thaws and forms a thin atmosphere primarily of nitrogen with a little methane and carbon monoxide. When Pluto travels away from the Sun the atmosphere then freezes back to its solid state.

starting from about 8pm bst we shall be able to see more of pluto’s surface.
