Radio astronomers have now made a new map of the radio sources near our galaxy's core.
Astronomers think our galaxy contains at least 100 billion stars, and perhaps as many as 400 billion.
This information is expected to unlock new information about the structure, origin and evolution of our Galaxy.
Right now there's a flux of stuff from other stars from our galaxy that's flying into the solar system.
We would have learned vastly more things about our region of our galaxy.
As an aside, we also tested the tags with our Galaxy Nexus and had no problem picking up the associated message.

There are tens of thousands of black holes, which can be formed by massive dying stars, in our galaxy, Levin said.
The current research estimates that there are at least 361 intelligent civilisations in our Galaxy and possibly as many as 38, 000.
"We now know the rate of occurrence of habitable planets around the most common stars in our galaxy, " said Prof Charbonneau.

New data from the Chandra X-ray Observatory indicates that this distorted supernova remnant potentially hosts the youngest black hole in our galaxy.

The Galaxy Camera is a fantastic example of our continued passion for innovation and we are excited to be evolving our Galaxy range even further.

Longevity or "L" is the last term in the Drake Equation, a formula designed to estimate the number of communicative civilizations in our galaxy.
Drake Deming, professor at the University of Maryland, points out that Earth can be seen transiting the sun from many vantage points throughout our galaxy.
Through the book we come to appreciate just how big our galaxy--not to mention the universe--is, while understanding how small life's essential particles and agents truly are.
But despite being millions of times more massive than our own Sun, the black hole at the centre of our galaxy would be relatively small in cosmic terms.
We might, for example, find the particles that make up more than 90% of the matter in our galaxy and all galaxies, which look dark to our eyes.
An analysis of small, dim "red dwarf" stars - which make up a majority of stars in our galaxy - shows that 6% of them host such a planet.

By the time any change occurred, humans might even have generated technology that could speed up the Earth's rotation or transport us to other liveable planets within our galaxy.
The Kepler mission has identified 132 planets beyond our solar system since its launch in 2009, leading scientists to believe that most stars in our galaxy have planets circling them.
"Samsung Epic 4G is a powerful member of our Galaxy S smartphone portfolio which offers premium screen, speed and content features, " said Omar Khan, chief strategy officer for Samsung Mobile.

Indeed, when Rees raises the prospect that the atom-smashers may not compact the planet, but instead create a novel vacuum that eliminates our galaxy, the reader can't resist a sci-fi cry of "coool!"
" This incredible image gives us a new perspective of our galaxy, and illustrates the far-reaching discoveries we can make from large sky surveys, " Nick Cross, of the University of Edinburgh, said in a statement.
Mars is more like Earth than any other place in the known universe, and while astronomers now believe there may be millions of earth-like planets in our galaxy, Mars is the only one that is within reach.
On 17 March 2005, Andrzej Udalski, professor of astronomy at Warsaw University, Poland, and leader of the Optical Gravitational Lensing Experiment (Ogle), noticed that just such an event was about to occur near the centre of our galaxy.
Yet, even roughly Earth-sized planets abound - more recent research suggests that one in six stars has a planet of about Earth's size in an orbit close to their host stars - making for at least 17 billion in our galaxy alone.

Welcome aboard, John, and thanks for adding another star to our growing galaxy of leadership experts.
Our own galaxy, which seems so immense, is just one among 100 billion galaxies.
No supernovae have been observed in our own galaxy since 1604, but astronomers have seen many supernovae in other galaxies since.
Most spiral galaxies, including our home galaxy the Milky Way, have a large concentration of ancient stars surrounding the centre that astronomers call the bulge.
