    So, this is a fascinating development from , the exploration and sea-floor mapping outfit. It's creating a new company called "Armada" that will command a fleet of Uncrewed Surface Vessels. h/t

    French start-up raises €100m for its Internet of Things constellation. The company name may not mean anything to you but "Argos" might. The venerable system for tracking the movement of animals worldwide. Kinéis has taken over this system.

    And here's your update on (AKA ). It too has been on the move. In the bottom right of this image you can see the ice segment that everyone long predicted would break free from the Amery Ice Shelf butt is still attached.

    So I know everyone's got their eyes on Pine Island Glacier because a biggish calving is imminent, but keep some of your gaze on . It really is motoring. Now poking above 63 degrees S and about to break free of surrounding sea-ice.

    And this. Eddington's photographic plate of the 29 May 1919 total solar eclipse that essentially told us that Mr Einstein's musings on general relativity were bang on. Amazing to witness these historic artefacts.

    So, you think the "first light" images of the Sun from the Daniel K Inouye Solar Telescope were cool. How about these? Just hanging out at the (as you do) and here is Carrington's drawing of the sunspot group that yielded his famous flare "event" in 1859.

    The US Government Accountability Office says the project "is now managing to a March 2021 launch date but estimates only a 12% likelihood that this date will be achieved. NASA plans to reassess the launch date in the spring of 2020."

    We're putting the spotlight on today on the BBC. And here's a graphic that illustrates how meltwater from the glacier doesn't make the oceans rise equally everywhere. The way the oceans work means the distribution is uneven.

    Like many of its neighbours in West Antarctica, has an Achilles heel. And that's the inclination of the seabed underneath the glacier which promotes further melting and mass loss as warm water increasingly impinges the underside of its floating front.

    The second thing about to recognise is that it's losing mass, and the rate of loss is accelerating.
