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.

Comic book character Archie Andrews is being killed off this month.
Bob Montana created the Archie comic book series in 1941. ”The Archie Show” cartoon debuted on CBS in 1968. The characters play in a pop rock band called The Archies, which produced a real-life hit single: ”Sugar, Sugar” hit No. 1 in 1969.
According to Wikipedia:

A typical episode started with the first Archie story, introduced by Archie and occasionally a different character. Next was a “dance of the week” segment starting with a teaser, then after the commercial break Archie introduced the dance, followed by the song of the week performed by The Archies. After that was a short joke followed by the 2nd Archie story. 

"The Archie Show" was the first Saturday morning cartoon to feature a laugh track. It lasted only one season, with 17 half-hour episodes at the end of its run, but the franchise continued for years in various formats. Later incarnations included an hour-long program, a show with live-action kids, a series in which the characters run a TV station and several other incarnations.
Most episodes were repurposed for syndication in 1976 under the title “The Archies.” The Family Channel later aired reruns in a half-hour format as “The Archie and Sabrina Surprise Package.” Retro Television Network aired reruns beginning in 2010.

"Three faces among the countless who belong to the New Culture, setting forth on a final voyage through a dying world…searching for a way to bring us all closer to home." — Inscription across the bottom of this block-long billboard for Grand Funk Railroad, which hung in Times Square for three months.
