Astronomers believe super-Earths are the most abundant planets in our galaxy. The term describes any world heavier than Earth but not as massive as gas giants like Saturn and Jupiter.

The planetary systems are in the deepest recesses of our galaxy and probe the early universe's 'Dark Ages', when dust obscured the cosmos and the first stars flickered into existence. Unique knowledge is expected to flow from
When completed, these machines will allow the world's astronomers to view the birth of thousands of planetary systems in the deepest recesses of our galaxy.
Even at 10%, the high possibility of life is overwhelming. There are at least a few hundred billion stars in our galaxy, which means that around 20 to 40 billion planets have the potential for the development of organisms.
Astronomer David Field of the University of Aarhus says, "The fainter the galaxy, the more distant it is. And given that light travels at a finite speed, faint galaxies are also the oldest."
Our Milky Way galaxy and the neighboring Andromeda galaxy are destined to collide! This illustration shows what the night sky might look like in 3.75 billion years.
“Space Lawyer” sounds like a job that’s too awesome to exist, but it’s not — you really can practice space law. It's a fascinating realm of study that's becoming more and more relevant as we get farther out into the galaxy.

There are at least 3 billion stars in the galaxy. And here is an idea of its size: For light from the middle of the galaxy to reach the sun, it takes about 27,000 years!
A new picture helps scientists unravel the mystery of a vast green blob discovered in a galaxy millions of light years away. Part of a streamer of gas stretching around the galaxy, it may be giving birth to new stars.

Discovered on Sept. 18, 2006, the explosion actually transpired in a distant galaxy about 238 million light years away -- meaning it happened about 238 million years ago.
