Re: Elon Musk promotion

The global population level is slowing and set to stabilise at 8 billion. It’s HOW we live at this point in time that’s fouling the nest. We need total system change, not half-baked reformist solutions. But that’s politics .. .

Re: IC 1805

I thought it was the Eagle neb because at the centre of the nebulosity there appear to be structures that look like the so-called Pillars of Creation.

Re: IC 1805

There’s plenty of extended detail in there. Are we looking at the Eagle Nebula?

Re: Elon Musk promotion

The Moon and Mars were messed up long before showman Musk burst onto the scene Mike, by asteroids and comets.

National star-count completed ..

The countryside charity CPRE has completed its survey with over 8000 results. The star count has revealed a ten percentage drop in people experiencing severe light pollution since February. The CPRE attributes this reduction probably to the Covid lockdown. The number of stars counted in Orion betwee...

Re: Another Interstellar Visitor Is Headed Our Way

Apparently, these interstellar visitors to the Solar System are more frequent than was previously thought.

Gosky sounds Russian like Gorky. It’s a company in America.

Re: Asteroid Apophis Flyby

A century from now they’ll easily be able to deal with rogue comets and asteroids. In fact, with proper planning they could do it now.

Re: Lonesome planet

What a revelation it would be Eva, if one of those thousand or so exoplanets so far discovered was found to have an atmosphere indicating possible life on the planet. :D

Re: Chang'e 5 on the Moon

In the 1970s, I did a geology course at a further education college. On one occasion, a lecturer from Manchester University gave a talk and brought with him a small glass vial containing Apollo lunar material. It looked like sand. With care the vial was passed round the class. The lecturer said that...
