The Visible Universe, Then and Now Before the telescope was invented in 1608, our picture of the universe consisted of six planets, our moon, the sun and any stars we could see in the Milky Way galaxy. But as our light-gathering capabilities have grown, so too have the boundaries of the visible universe. Our interactive map shows how the known universe has grown from 1950 to 2011. In the late 1700s, William Herschel, an English astronomer using a telescope with an 18.7-inch aperture, made the first systematic surveys of the skies, revealing more than 2,000 distant galaxies, nebulae and other objects invisible to the naked eye.

[SURVEY STUDY] +46% Of a brand’s Twitter followers are bots Twitter has proven itself as a fantastic community-building resource for brands of all shapes and sizes, but new research has suggested that the follower counts of these company profiles might not be as receptive to product and sales messages as their marketers might have hoped. That is, unless they’re using Twitter to sell oil baths. Marco Camisani Calzolari, a professor of corporate communications and digital languages at Milan’s IULM University, analysed the Twitter networks of 39 major consumer brands, including Samsung, Starbucks, Blackberry, Wholefoods and Pepsi, and discovered that an alarming number of their followers were provably non-human – that is, bots, or other fake accounts. And in the case of @DellOutlet, that number was as high as 46 percent. That’s right – almost half of @DellOutlet’s 1.5 million strong network is made up of non-human accounts. Dell were understandably tetchy about the results.

New Tweets per second record, and how Recently, something remarkable happened on Twitter: On Saturday, August 3 in Japan, people watched an airing of Castle in the Sky, and at one moment they took to Twitter so much that we hit a one-second peak of 143,199 Tweets per second.

This particular spike was around 25 times greater than our steady state.

How black people use Twitter. - By Farhad Manjoo As far as I can tell, the Twitter hashtag #wordsthatleadtotrouble got started at about 11 a.m. Pacific Time on Sunday morning, when a user named Kookeyy posted this short message: "#wordsthatleadtotrouble 'Don't Worry I gotchu." A couple minutes later, Kookeyy posted another take on the same theme: "#wordsthatleadtotrouble - I Love Yuh *kiss teeth*." On Twitter, people append hashtags to categorize their messages—the tags make it easier to search for posts on a certain topic, and they can sometimes lead to worldwide call-and-response conversations in which people compete to outdo one another with ever more hilarious, bizarre, or profane posts. A woman in South Africa named Tigress_Lee moved the chatter in that direction: "#wordsthatleadtotrouble 'the condom broke'!"

An Annual Report on One Man's Life Nick Bilton/The New York TimesNicholas Felton and his 2008 annual report.

Twitter *Is* A Newsroom Earlier this morning Twitter released “Twitter for Newsrooms,” its primer on how to use Twitter to gather and report news in the 21st century. #TfN is Twitter’s official nudge to old school reporters, a heavy handed reminder to get with the program and embrace Twitter as media production and consumption device. The company’s missive to journalists is pure straight talk, “We know you come from different generations. Some are native to the pilcrow, others native to the hashtag. You began your careers in different media: radio, print, broadcast, online and mobile.” … And you have all somehow ended up on Twitter.
