Our sun’s long-lost stellar sibling found at last, astronomers say

A star born from the same cloud of gas as our sun 4.5 billion years ago has been found at last, astronomers say.

This solar sibling is a little bigger than our sun, and a little hotter at its surface. But an international team of researchers says it has the same chemical fingerprint as the star at the center of our solar system, leading them to conclude both stars were born in the same stellar nursery, at the same time.

“Stars that were born in different clusters have different compositions,” said Ivan Ramirez, an astronomer at the University of Texas at Austin. “If a star has the exact same chemical composition as our sun, that establishes that they were born in the same place.”

Ramirez is the lead author of a paper about the discovery that will be published June 1 in the Astrophysical Journal.

Like most stars, our sun emerged from an immense cloud of gas and space dust that gave rise to 1,000 to 10,000 stars. Those baby stars stayed clustered together for hundreds of millions of years — a relatively short time on the astronomical scale.

But as they grew up, their cluster broke up and the individual stars began to drift apart. Billions of years later, these stellar siblings are now scattered across the Milky Way galaxy.

Our sun’s newly discovered solar brother from the same gas-cloud mother is known as HD 162826. It is just 110 light years away from our sun, which Ramirez said is remarkably close.

“It is almost certain that if there is another star like this one this close to us, we would have found it already,” he said, “so the next siblings we find are going to be further away.”

Ramirez wasn’t expecting to find a solar sibling even this close to our own sun. In an interview with the Los Angeles Times, he explained that the original intent of his research was to determine efficient ways of identifying our sun’s closest relatives in the future when surveys like space-based telescope Gaia’s provide astronomers with a flood of new data.

Crowdfunded Tesla tower project seeks to recreate inventor’s wireless energy transmission system

By many accounts, the iconic inventor Nikola Tesla was years ahead of his time. His ideas for a worldwide wireless communications system, and a wireless energy transmission technology, never got the traction they perhaps may have deserved during his lifetime, and but now, over a century later, two scientists are retracing his steps and plan to build a prototype of his Wardenclyffe tower using modern materials and advanced electronics.

The Planetary Energy Transmitter project seeks to crowdfund $800,000 in donations in order to build the Tesla Tower prototype, and to continue Tesla’s research intowireless energy transmission and reception, which is intended to demonstrate the viability and efficiency of the technology. If the prototype functions as intended, and further research into wireless power reception plays out as well, the Tesla tower and wireless receivers could “allow transmission of large amounts of energy via ground to any kind of distances – instantly, safely and without losses.”

Tesla was right and we are ready to prove it!

Tesla Releases Patents in Unprecedented Move to Advance Electric Vehicles

Other automakers, you, too, can build like Tesla.

CEO Elon Musk says so.

Tesla is now an open-source company, allowing its electric vehicle patents for outside use. Musk made the unprecedented announcement Thursday on his company’s blog.

“Tesla Motors was created to accelerate the advent of sustainable transport,” he wrote. “If we clear a path to the creation of compelling electric vehicles, but then lay intellectual property landmines behind us to inhibit others, we are acting in a manner contrary to that goal.

“Tesla will not initiate patent lawsuits against anyone who, in good faith, wants to use our technology.”

Robert David Steele, former Marine, CIA case officer, and US co-founder of the US Marine Corps intelligence activity, is a man on a mission. But it’s a mission that frightens the US intelligence establishment to its core.
With 18 years experience working across the US intelligence community, followed by 20 more years in commercial intelligence and training, Steele’s exemplary career has spanned almost all areas of both the clandestine world.

Steele started off as a Marine Corps infantry and intelligence officer. After four years on active duty, he joined the CIA for about a decade before co-founding the Marine Corps Intelligence Activity, where he was deputy director. Widely recognised as the leader of the Open SourceIntelligence (OSINT) paradigm, Steele went on to write the handbooks on OSINT for NATO, the US Defense Intelligence Agency and the U.S. Special Operations Forces. In passing, he personally trained 7,500 officers from over 66 countries.

In 1992, despite opposition from the CIA, he obtained Marine Corps permission to organise a landmark international conference on open source intelligence – the paradigm of deriving information to support policy decisions not through secret activities, but from open public sources available to all. The conference was such a success it brought in over 620 attendees from the intelligence world.

Elon Musk and SolarCity Executives Announce Plan For World’s Largest Solar Panel Production Plant

Musk is also chairman of SolarCity, a firm responsible for three times the solar panel installations as its closest competitor. Along with executives Peter Rive and Lyndon Rive, Musk announced this week that the company will create a solar plant that would be the equivalent ofTesla’s “gigafactory” plan announced earlier this year.

“We are in discussions with the state of New York to build the initial manufacturing plant, continuing a relationship developed by the Silevo team. At a targeted capacity greater than 1 GW within the next two years, it will be one of the single largest solar panel production plants in the world,” the trio wrote in a company blog post.

Researchers have worked out how to make matter from pure light and are drawing up plans to demonstrate the feat within the next 12 months.

The theory underpinning the idea was first described 80 years ago by two physicists who later worked on the first atomic bomb. At the time they considered the conversion of light into matter impossible in a laboratory.

But in a report published on Sunday, physicists at Imperial College London claim to have cracked the problem using high-powered lasers and other equipment now available to scientists.
