In the 1990s, they worked out one Venusian day – the time for the planet to spin round once – lasted 243.018 Earth days.
But now, the European Space Agency’s Venus Express orbiter shows Venus’ spin is getting even slower and a day on Venus is now six and a half minutes longer.
Scientists aren’t sure why.
It doesn’t matter. There are far more pressing things to be looking this. Scientists – and indeed the people that fund these things – should be looking at humanity now and doing what they can now because the now is far far more important.
You’d stop a kid daydreaming and tell them to get on with things wouldn’t you? So what makes these grownups special?
