    We instinctively think of planets as rocky or gaseous bodies orbiting a star like our sun, with sunrise, sunset, heating and maybe even seasons. But what if a planet didn't orbit a light source? What if it just floated through space vaguely orbiting the centre of the galaxy, but tugged this way and that way by nearby stars and stellar systems. These are rogue planets. No sunrise, no sunset, no heat from an outside source. Just starlight and blackness as it wandered aimlessly through lonely interstellar space. And they just might be the most common type of planet in our galaxy.

  • #88 Is the Universe Infinite? It’s almost an instinctive question, but maybe it’s unknowable.

    Most people have looked to the skies and wondered if the universe has a boundary, or maybe it goes on for ever. The universe might be finite, with and end somewhere. Or, it might be infinite, with an infinite amount of space and matter. Both of thos throw up some mind bending questions, and maybe even real life duplicates of ourselves. Problem is, we would never be able to observe them, or even test for their presence, or even know if they exist. So does it matter?

    The launch window for Artemis II opens on 6 February 2026. Humans will fly a test mission, swinging around the far side of the moon for the first time since Apollo 17 in 1972. There won’t be a landing, but just like Apollo 8 tested systems in the lunar vicinity before Apollo 11, Artemis II will test the modern systems under the same conditions the landing missions. There will be a crew of 4 including the first person of colour, the first woman and the first non American to fly beyond low Earth orbit. It really is a historic flight in so many ways.
