this is the single saddest post I have ever seen on tumblr.

I relate so much

i posted this as a joke why does it have 3,000 notes and hipster urls everywhere it was probably a homeless crack addict who got hold of a spray can


Well maybe because to some people it does mean something. I reblogged it and then read your comment and it means something to me because I dropped out of school freshmen year and would be graduating right now. Just because it’s a joke to you, doesn’t mean it is to everyone.

Mapping the Mass of an Enormous Galaxy Cluster

You are looking at the most precise gravity map ever made of a distant galaxy cluster. Using the map, astronomers have determined that the cluster is roughly 650,000 light-years across and contains enough matter to make 160 trillion suns.

The cluster, known as MCS J0416.1–2403, is located about 4 billion light-years away and consists of hundreds of galaxies all orbiting one another. Newton’s gravitational equations can tell you the mass of two objects orbiting one another, provided you already know the mass of one of them. However, because these galaxies are all so distant, there is no way for scientists to determine any of their individual masses.
But there is another way. Einstein’s theory of general relativity tells us that heavy objects warp the fabric of space-time around them. As light travels through these warped regions it will become distorted, and we see that as smeared out rings and arcs in our telescopes, an effect known as gravitational lensing. Using the Hubble space telescope, astronomers identified smudges in the light seen around MCS J0416.1–2403. These distortions are images of even more distant galaxies sitting behind the cluster; their light has been lensed by its enormous mass. By carefully determining just how much the light is smeared out, researchers can calculate the amount of matter sitting within the galaxy cluster.
The 160 trillion solar masses includes both visible matter and dark matter, which gives off no light but makes up the bulk of the cluster’s mass. By studying the dynamics of all the galaxies within the cluster, astronomers can better understand this mysterious substance. Researchers will also continue mapping the smeared out images to increase the precision of their mass calculations, learning about the cluster’s finer details to figure out its history and evolution.

sorry satan, I was kinda busy

No matter what I totally would have taken this call.

I’m reblogging this again because I love the message behind it and I think it needs to be passed on.

The Cassini spacecraft looks down on the north pole of Saturn. The scene is serene only from a distance—raging storms are clearly visible in the atmosphere. In this image you can even make out Saturn’s hexagonal storm. The hexagonal vortex is about 20,000 miles (30,000 km) across and is a jet stream made up of 200 mph winds (322 km/h) surrounding a huge storm, Scientists have not found another weather feature exactly like this anywhere in the solar system.
