An animation showing the 1.255 light second distance between us and the moon (the Sun is about 8 light minutes from us) created by planetary scientist Dr. James O’Donoghue using NASA imagery. and that’s not all. To wit:

This is the distance between the Earth and Moon with the correct sizes and scales. The real-time speed of light is also shown.

For the day that’s in it, YouTube learning channel Kurzgesagt explores the possibility of humanity progressing from a near Type I planet harvesting civilisation (on the Kardashev scale) to a Type II star harvesting civilisation.

It’s easy. All we need to do is build a Dyson Sphere, or Dyson swarm around the sun and tap its power.

Next Tuesday alright for you?

Late last month, NASA’s Insight mission probe landed on the Martian surface and began sending data from various measuring instruments, including an air pressure sensor and a yet-to-be fully deployed seismometer.

Both (in their own way) heard the sound of the martian wind.

YouTube education channel Kurzgesagt explores the increasing hazard caused by every new rocket we launch into space and the deadly cloak of debris that may one day make space travel too dangerous to attempt.

Data scientist Neil Kaye shows how the ubiquitous Mercator Projection distorts the real scale of countries (dark blue = actual size in the map above).

The visualisation shows land masses nearer the Poles [including our own] to be much larger than they actually are.

Take aways: Mercator Alaska is larger than Mexico (it’s not). Mercator Russia is ridiculously exaggerated (it is). Africa is very large indeed.

Web education channel Kurzgesagt explains why meat is the best worst thing in the world.

Which is to say, it’s the worst, least efficient, most environmentally damaging and ethically dubious thing.

Nano-scale images of kidney stones from a report published recently in the Journal of Scientific Research showing the painfully-passed little buggers as strangely beautiful microscopic coral reef like structures, very different to the homogenous, insoluble nuggets they were once thought to be.
