A real life Planet Midnight?

Doctor Who has inadvertently predicted many things, from the iPad in the 80s to a second Earth in ‘New Earth’, but now it something far more interesting has come along. Astronomers have now recently spotted an “exotic planet, that seems to be made of diamond, racing around a tiny star in our galactic backyard”.

As you’ll remember, way back in 2008 there was an episode in Series Four (episode 10, to be precise) called ‘Midnight’, which was set entirely in the future on the planet Midnight – a planet made entirely out of diamond. We all recall how the Tenth Doctor got into a bit of a pickle and almost got thrown out of the tourist buggy into the fatally strong “Xtonic radiation” that would vaporise any unprotected living thing on its surface in a split second!
The new planet is far denser than any other known so far and consists largely of carbon. Because it is so dense, scientists calculate the carbon must be crystalline, so a large part of this strange world will effectively be diamond. The evolutionary history and amazing density of the planet all suggest it is comprised of carbon -- i.e. a massive diamond orbiting a neutron star every two hours in an orbit so tight it would fit inside our own Sun," said Matthew Bailes of Swinburne University of Technology in Melbourne.

Lying 4,000 light years away, or around an eighth of the way toward the centre of the Milky Way from the Earth, the planet is probably the remnant of a once-massive star that has lost its outer layers to the so-called pulsar star it orbits. Pulsars are tiny, dead neutron stars that are only around 20 kilometres (12.4 miles) in diameter and spin hundreds of times a second, emitting beams of radiation.

The measurements suggest the planet, which orbits its star every two hours and 10 minutes, has slightly more mass than Jupiter but is 20 times as dense, Bailes and colleagues reported in the journal Science on Thursday. In addition to carbon, the new planet is also likely to contain oxygen, which may be more prevalent at the surface and is probably increasingly rare toward the carbon-rich centre.

Its high density suggests the lighter elements of hydrogen and helium, which are the main constituents of gas giants like Jupiter, are not present. Just what this weird diamond world is actually like close up, however, is a mystery. In terms of what it would look like, I don't know I could even speculate," said Ben Stappers of the University of Manchester. "I don't imagine that a picture of a very shiny object is what we're looking at here."

Let’s just hope they never build a Leisure Palace or set up any shuttle buss tours across this planet then, eh?

  1. In which episode do we see the iPad like device??? Just curious.

    I'm not entirely sure as I can't remember :P
    But I do remember it and I'm 99% certain it was a Davison story. I know that doesn't narrow it down a great deal, but you can at least cut out all the ones set in the past. :)
    If I remember I'll get back to you on it


Do you want Christopher Eccleston back for the 50th Anniversary?
YES!! - That would be absolutely brilliant!
Not sure - I'm not bothered either way, to be honest...
No - it's good to see the back of 'im!
