I still recall looking at pedestrians(!) while driving, and hearing a cold voice in the car asking "Is she nice?..."

driving with the family a few years back and after a few good looks  and comments ,my duaghter says:" Dad! you are worse than Johnny Bravo!" My wife just laughed. she is so used to me.

This is pretty exciting I think. Love all the space stuff. Just wish I was intelligent enough to really understand it.

Here it is...

A black hole and its shadow have been captured in an image for the first time, a historic feat by an international network of radio telescopes called the Event Horizon Telescope (EHT).

A black hole is an extremely dense object from which no light can escape. Anything that comes within a black hole’s “event horizon,” its point of no return, will be consumed, never to re-emerge, because of the black hole’s unimaginably strong gravity. By its very nature, a black hole cannot be seen, but the hot disk of material that encircles it shines bright. Against a bright backdrop, such as this disk, a black hole appears to cast a shadow.  

The stunning new image shows the shadow of the supermassive black hole in the center of Messier 87 (M87), an elliptical galaxy some 55 million light-years from Earth. This black hole is 6.5 billion times the mass of the Sun. Catching its shadow involved eight ground-based radio telescopes around the globe, operating together as if they were one telescope the size of our entire planet.

Just a little more on the black hole photo, I don't think enough people realise the significance of the image, and how difficult it is to photograph.

 

Here is a TED Talk from over a year ago by Dr Katie Bouman, one of the members of the team, who created the algorithm making the image possible, explaining it in more detail. It's truly fascinating stuff
