It's a Sainsburys placcy bag. Just the light reflecting off it. ****ing things get everywhere.
Monster "El Gordo" Galaxy Cluster is Bigger Than Thought

This is a composite image of X-rays from Chandra and optical data from Hubble of the galaxy cluster ACT-CL J0102-4915, located about 7 billion light years from Earth. This cluster has been nicknamed "El Gordo" (or, "the fat one" in Spanish) because of its gigantic mass.
Scientists first announced the discovery of El Gordo with Chandra and ground-based optical telescopes in 2012. They determined that El Gordo is the most massive, the hottest, and gives off the most X-rays of any known galaxy cluster at its distance or beyond.
New data from the Hubble Space Telescope suggests El Gordo weighs as much as 3 million billion times the mass of our Sun. This is about 43 percent higher than the original estimate based on the X-ray data and dynamical studies.
The new Hubble study determined that most of the mass is hidden away as dark matter. The location of the dark matter is mapped out in this composite in blue. Because dark matter doesn't emit any radiation, astronomers instead precisely measure how its gravity warps the images of far background galaxies like a funhouse mirror. This allowed them to come up with a mass estimate for the cluster. Chandra's X-ray data are shown in pink and these have been overlaid on optical data from Hubble that shows the individual galaxies in the cluster as well as stars in the field of view.
The X-ray image of El Gordo reveals a distinct cometary appearance. Along with the optical data, this shows that El Gordo is, in fact, the site of two galaxy clusters running into one another at several million miles per hour. This and other characteristics make El Gordo akin to the well-known object called theBullet Cluster, which is located almost 4 billion light years closer to Earth.
As with the Bullet Cluster, there is evidence that normal matter, mainly composed of hot, X-ray bright gas, has been wrenched apart from the dark matter in El Gordo. The hot gas in each cluster was slowed down by the collision, but the dark matter was not.

Just remember that you're standing on a planet that's evolving
And revolving at nine hundred miles an hour
That's orbiting at nineteen miles a second, so it's reckoned
A sun that is the source of all our power
The sun and you and me and all the stars that we can see
Are moving at a million miles a day
In an outer spiral arm, at forty thousand miles an hour
Of the galaxy we call the 'milky way'
Our galaxy itself contains a hundred billion stars
It's a hundred thousand light years side to side
It bulges in the middle, sixteen thousand light years thick
But out by us, it's just three thousand light years wide
We're thirty thousand light years from galactic central point
We go 'round every two hundred million years
And our galaxy is only one of millions of billions
In this amazing and expanding universe
The universe itself keeps on expanding and expanding
In all of the directions it can whizz
As fast as it can go, the speed of light, you know
Twelve million miles a minute and that's the fastest speed there is
So remember, when you're feeling very small and insecure
How amazingly unlikely is your birth
And pray that there's intelligent life somewhere up in space
'Cause there's bugger all down here on Earth
Makes you feel quite insignificant doesn't it?
Is that all youve got to offer???
It's the entire ****ing universe, what more do you want?
Now that hurts....
It was tongue in cheek Tigre
So you agree it's a placcy bag?
All of that for 5p? ****ing amazing.
