- Star Astronomy
Astronomy is as large as the universe that it seeks to discover. Star astronomy is just one part of the overall science and hobby. It would take a lifetime just to learn about all the objects that orbit our own small sun. Some people, then, decide to...
- Planets Like Binary Stars, Too
In our solar system, planets, comets, asteroids, and dwarf-planets all orbit around a single star, our Sun. But imagine if we could witness two Suns in our sky. NASA's Spitzer Space Telescope has helped astronomers see that planetary systems are...
- Most Earth Like Worlds Have Yet To Be Born.
According to a new theoretical study, Earth came early to the party in evolving universe. When our solar system was born 4.6 billion years ago, only 8 percent of the potentially habitable planets that will ever form in the universe existed, which means 92...
- Our Neighbors In Space
We have a special feeling toward the other planets that circle our sun. Maybe it?s all the science fiction stories about visiting the moon, Mars and other planets. But we love to think about those planets that make up what we call ?the solar...

The history of Hubble Space Telescope
The Hubble Space Telescope has cost U.S. taxpayers some $10 billion in the quarter century since the project was approved. But to astronomers around the world, the high-flying satellite is, in a word, priceless.
The solar-powered spacecraft has helped astronomers confirm the existence of super massive black holes, pin down the true age of the universe and spot the faint building blocks of the first galaxies as they collided, merged and grew just a billion years or so after the birth of the cosmos.
Its mind-bending photographs have charted the life cycles of distant suns in unprecedented detail, providing unmatched views of the vast stellar nurseries where stars are born to the supernova bangs and whimpers marking old age and death.
It has catalogued myriad infant solar systems in the process of forming planets and provided flyby-class views of the outer planets in Earth's own solar system, routinely capturing phenomena as common as dust storms on Mars to once-in-a-lifetime events like the 1994 crash of a comet into the atmosphere of Jupiter.
