In its early stages of development, LIVESTREAM television employed a combination of optical, mechanical and electronic technologies to capture, transmit and display a visual image. By the late 1920s, however, those employing only optical and electronic technologies were being explored. All modern television systems relied on the latter, although the knowledge gained from the work on electromechanical systems was crucial in the development of fully electronic television.

According to a report from the International Centre for Radio Astronomy Research (ICRAR), astronomers have found a powerful black hole, named MQ1, in the nearby galaxy M83. Previously, astronomers have located several compressed objects that are as powerful as MQ1, but have not been able to determine the size of the black hole contained within them until now.
Using several telescopes, the astronomers found that the MQ1 system is a standard-sized small black hole, as opposed to a somewhat larger version that was hypothesized to account for all its power.
“MQ1 is classed as a microquasar - a black hole surrounded by a bubble of hot gas, which is heated by two jets just outside the black hole, powerfully shooting out energy in opposite directions, acting like cosmic sandblasters pushing out on the surrounding gas,” noted team leader Dr. Roberto Soria, who is part of ICRAR, in a statement.
“The significance of the huge jet power measured for MQ1 goes beyond this particular galaxy: it helps astronomers understand and quantify the strong effect that black hole jets have on the surrounding gas, which gets heated and swept away,” he added.
According to astronomers, the most powerful microquasar in the Milky Way, called SS433, is approximately 10 times less powerful than MQ1.
With the help of NASA’s Hubble Space Telescope, astronomers determined that the jets around the MQ1 structure extend approximately 20 light years from either side of the black hole.
MQ1 is a stellar-mass black hole, meaning that it is less than approximately 70 times the mass of our Sun, and was likely formed when a star died, collapsing to leave behind a compact mass. NASA notes that stellar-mass black holes usually weigh between five and ten times the mass of our Sun.
The finding of MQ1 and its features is just one of the discoveries of the exhaustive study of galaxy M83.

SNOWDEN ON GOOGLE HANGOUTS IN AUSTIN TX
Snowden, a former CIA technician, addressed the audience in Austin, Texas, in a live broadcast using Google Hangouts, given the web giant's involvement with surveillance of the population. He claimed government spies were "setting fire to the future of the internet."
But the SXSW organizers joked that Snowden's video signal, presumably originating from somewhere in Russia, was being bounced off "seven different proxies" before hitting the Chocolate Factory's video chat software. In an hour-long session, Snowden discussed the state of surveillance, how it could be countered, and took questions from the public - including a query from Sir Tim Berners-Lee, who asked for the "privilege" of the first question.
"Your actions were profoundly in public interest. If you could design a system from scratch, an accountability system for governance over national security agencies, what would you do," the World Wide Web creator asked during the webcast's Q&A.
"It's clear that intelligence agencies are going to be using the internet to collect information from all of us, is there any way we can make oversight more accountable and improved?"
Snowden said there were technological measures that could be used - tools to encrypt communications and thwart tracking, for example - but the biggest issue was in layer eight of the network: in other words, the difficulty in getting ordinary people to use technology effectively and the politics preventing that from happening. Crypto and privacy systems are useless if humans won't, can't or are forbidden from using them properly.
As an example of the political problem, the whistleblower highlighted the fact that the US director of national intelligence James Clapper misled US Congress and suffered no rebuke. Snowden accused congressional overseers of failing to protect privacy and "cheerleading for the NSA."
What was needed, he said, was for independent public figures to have an oversight role in the intelligence community. They are needed to scrutinize spies and Congress, and make sure they are being honest. But internet users need to be responsible, too.
Gear up, it's encryption for all
On a most basic level, the only way forward to combat mass surveillance is for a corresponding mass encryption of data, Snowden said. The NSA has poured money into cracking algorithms and protocols, and has managed to subvert a few too, but the agency was thwarted by the sound mathematics at the heart of every good cipher; strong cryptography exists and should be relied upon.
Snowden said that strong crypto will hold until "concepts of mathematics and physics change on a fundamental level."
He advised netizens to ensure their hard drives and all their network connections are securely encrypted end to end so as to avoid mass surveillance. Doing so would force government eavesdroppers to focus on compromising particular targets rather than operate today's planet-wide dragnets, which effortlessly pull in pretty much everyone's unprotected internet traffic - whether or not they were suspected of any wrongdoing.
Ciphering everything would derail that approach by making it too costly or too much hassle for government snoopers.
Thus, while almost no one can stop the NSA actively hacking your PC and stealing your secret keys, he said, just adding basic encryption on a mass scale could vastly improve the situation for millions of spied-upon innocents. And that needs developers to step up to the plate.
"There's a technical response that needs to occur. It's the makers, it's the thinkers, it's the development community that can really craft the systems to make sure we're safe," Snowden told the conference. "This is a global issue. They are setting fire to the future of the internet and the people who are in this room now are the firefighters and we need you to help us fix this."
Developers can help enforce standards of privacy even though the US Congress hasn’t got around to enforcing them, Snowden said. Software needs to pass a Glen Greenwald stupidity test, the ex-contractor added, referring to the careful coaching he had to give the journalist in how to communicate securely using PGP before he could leak a cache of top-secret documents about the US and UK's online surveillance programs.
"This is something people have to be able to access and really the way we interact with it now is not good," Snowden said.
"If you have to go to the command line people aren’t going to use it. If you have to go three menus deep, people aren’t going to use it. It has to be out there, has to happen automatically, and it has to happen seamlessly."
