Distant Galaxies and Nearby Nuts

Far away, on the edge of our galaxy lies a teeny tiny other galaxy - except that this one (M60-UCD1) has a humongous black hole to outshine (in a dark sense) any other.
It has a mass of 21 million suns.
But fear not, it won't be devouring Earth anytime soon - it's 50 million light years distant.
On the other hand, we also know that the light we see from M60-UCD1 is showing us how it was 50 million years ago, so it could already be gone.
And the bottomless time distorting maw of the black hole could be looming ominously overhead, even as we speak.
Which is cheerful.
Sorry...

 Our night sky (viewed away from big cities and their light pollution), contains 4000 stars.
Which is quite a lot, if you ask me - but M60-UCD1 contains 140 million stars, of which 1 million  are visible simultaneously (if there was an Earthlike world there, and you looked to the night sky).


This is an artists impression of the galaxy M6 UCD1

On the similar but opposite end of the spectrum, we have Triangulum II , a really tiny ghost galaxy with a paltry 1000 stars - but the largest detectable quantity of dark matter.


To put the old space race in perspective, there was a nuclear powered spacecraft that was considered for travel to Saturn - in 1958 . It was known as the Orion project, and would have been propelled by exploding hundreds of atomic bombs ....



Oddly enough, the current craft for Mars is also known as the Orion, although its proposed use of nuclear fuel is a little less dynamic...
NASA have revealed their reluctance , however, to engage in deep space travel -
which, given the proposed 2030 manned landing on Mars gives cause for concern - personally I think the journey will be made by a commercial firm - SpaceX and Blue Origin seem capable, although almost certainly with a rather more cavalier attitude towards health and safety...
Recent announcements state the terrible risks involved, apart from issues like loneliness and 'cabin fever', the very real threat of meteor impact, cancer and fatal irradiation.

Recent revelations tell us that the humble water bear or Tardigrade has no less than 17.5 % of  its DNA adapted from other species ; the process by which it does so is unknown, but it surely makes them the prize candidates for deep space travel , with their resistance to extremes of temperature and lethal doses of radiation - they have already been to space (and seem decidedly alien after all) ...
On the other hand, shouldn't we be concentrating on Terraforming, right now ?
Certainly the Moon needs a makeover, what with all that greyness and corrosive moondust.

There is a new mission called Luna 27 which aims to establish a presence in the lunar South Pole  in 2020, so we should spruce it up a little...at least a shiny shopping mall or two.
Perhaps with Holsts Planet Suite as piped muzak.
I'm joking of course, but seriously - recent laws passed Stateside allow for the mining and possession of minerals occuring in asteroids.
This piece of unilateral granting of rights strikes me as a tad premature.
Do we know of any other body perhaps laying claim to mining rights or even ownership of our asteroid belt ?
I'm getting into Hitchhikers Guide to The Galaxy territory here, but let me pause to show this -

Bill passed recently in the U.S.A.

In my slightly naive way, I'm amazed that this is a real document .
Funny how reality is mimicking fiction on an almost daily basis now.
Just this morning , I was ruminating on the fact that we live in a world where The Man In The High Castle is a popular media show.

Original edition cover . Fair Use is invoked.

That such an obscure work by Phillip K. Dick should be fĂȘted, restores my faith in humanity.
Then I get a rude awakening with endless news from the GOP rallies in the US, and I think how bizarre that reality Trumps fiction - in a cartoon way, almost.


To my mind, the evil spectre of modern Nazism was effectively lampooned in the film Iron Sky, in which a thinly veiled Sarah Palin - lookalike aims to lead the exiled Nazis from their hidden moonbase , on a warpath back to reclaim Earth.
Which was darkly funny.
Because it would never really happen...


Meanwhile, back in space...

The buzz at the moment seems to be around black holes - what they look like, how they grow, their potential for swallowing entire planetary systems, that sort of thing.
With this in mind, I share this download and print DIY  black hole game!
Fun for all the family - unless you lose the game and have to watch 'Event Horizon', with its grand guignol horrors , in which deep space exploration invokes a hellish reality . .literally.

In Closing...

 I am UK based and have been attempting to ignore the encroaching 'Black Friday' consumer thing - but Cards Against Humanity won the day for me, with their 'Nothing' sale, in which they sold absolutely nothing at five dollars a go, and raised over $70, 000 !
An admirable response to the lure of pure consumerist greed , except that I am also annoyed at my own failure to see the potential wealth inherent in exploiting irony. dammit.
